The best and worst moments from the Wizards’ 121-102 win in Game 4 at Verizon Center.

Best home-court advantage: The Wizards improved to 4-0 against the Celtics at Verizon Center this season and remained unbeaten at home in the playoffs to even the series at two games apiece. Game 5 is Wednesday in Boston.

Best backcourt: John Wall and Bradley Beal combined for 56 points, while Wall added 12 assists and five steals.

Worst disappearing act: Isaiah Thomas made his first five three-point attempts and appeared headed for another monster game, but 17 of his 19 points came in the first half.

Best manners: After they combined for eight technical fouls and three ejections in a chippy Game 3, the Wizards and Celtics kept their emotions mostly in check Sunday. A frustrated Thomas was whistled for the game’s first technical with 6:37 to play and Washington leading by 23. He promptly took a seat on the bench to start resting up for Game 5.

Best honesty: During a second-half timeout, Wizards Coach Scott Brooks told his team, “You guys are good, but I didn’t think you were gonna be this good.”

Best quarter: The Wizards weren’t just good in the third quarter, they were sweep-the-Cavaliers dominant, outscoring the Celtics 42-20 in the frame to take a commanding 22-point lead into the fourth. The 42 points were Washington’s most in a quarter in a playoff game since the Bullets scored 43 in a quarter against Philadelphia in 1971.

Best run: Bradley Beal had a relatively quiet first half, but scored eight points during a 26-0 Wizards run early in the third quarter that turned a 53-48 deficit into a 21-point lead.

Worst turnovers: The Wizards finished with one more turnover (19) than the Celtics, but Boston’s carelessness with the ball helped fuel Washington’s third-quarter blitz.

Best crowd: This was the scene inside Verizon Center after Washington’s 26-0 run, which didn’t even involve free chicken.

Best chant: When Markieff Morris stepped to the line with less than three minutes to play in the third quarter after a foul on Kelly Olynyk, fans started chanting, “Kel-ly Ou-bre! Kel-ly Oub-re!”

Best assist: John Wall scored all 14 of his first-half points in the final 6:22 of the second quarter, but his top highlight was this spinning drive and dish to Marcin Gortat. The Wizards used a 20-8 run to pull even, 48-48, at the break.

Worst shooting percentage: Zero. Wall finally cracked the scoring column with a couple of free throws to cut Boston’s lead to eight with 6:22 remaining in the first half, but the Wizards point guard missed his first nine shots.

Best confidence: Wall made three of his next four shots, including a three-pointer as part of an 11-2 Wizards run that pulled Washington to within 42-39.

Best IT: Okay, who knocked out another one of Isaiah Thomas’s teeth after Game 3? The Celtics point guard made his first five three-pointers and eclipsed his point total from Thursday’s loss less than two minutes into the second quarter to help Boston build a double-digit lead.

Worst deficit: The Wizards led by no fewer than 13 points after one quarter in Games 1,2 and 3. On Sunday, they trailed 24-20 entering the second quarter and John Wall was 0 for 5 from the field.

Worst B-roll: Weirdest B-roll, anyhow. That TNT is using Verizon Center footage from an old Capitals game is just more fuel for John Wall’s contention that the Wizards don’t get the national respect they deserve.

Best boos: The Verizon Center crowd booed every time Kelly Olynyk touched the ball, because #FreeOubre, and erupted in cheers when he missed the first of two free throws late in the first quarter. There’s no word on whether Olynyk is still welcome at the Italian Store in Arlington.

Best Otto: Averaging 16 points per game this series, Otto Porter Jr. continued his strong play Sunday with 10 points in the first 10 minutes. He finished with 18 points, eight rebounds and four steals.

Best start: What else is new? Washington outscored the Celtics, 119-70, in the first quarter in the first three games of the series and built a 22-point lead after 12 minutes en route to Thursday’s blowout win. The Wizards led 8-0 on Sunday before the Celtics scored.

Best statement: Wizards owner Ted Leonsis is sitting courtside as usual and showing his support for Kelly Oubre Jr. by wearing his No. 12 jersey. Three years ago, Leonsis did the same thing for Nene when the Wizards’ big man was suspended for Game 4 of a first-round series against the Chicago Bulls. Washington won that game.

What you need to know

● You know where Otto Porter Jr. got his name from, writes Jerry Brewer. His sweet shooting stroke, however, came from his mother. “He’s come a long way,” said Elnora Timmons Porter, a former high school star. Now, however, “He needs to start shooting more.”

That fire Brandon Jennings fueled in the Wizards-Celtics series? It started in Compton. When the Wizards’ backup point guard wants to make an impact, he mimics his days as a playground pest.

● NBA top cop Kiki VanDeWeghe explained to Tim Bontemps why Kelly Oubre Jr. had to be suspended for Game 4. “It was a non-basketball play, it was a very dangerous play, and you can’t retaliate in that type of manner.” Coach Scott Brooks noted his team’s “next man up mentality” when discussing the suspension on Saturday. The Wizards’ already-thin bench will be even thinner come Sunday evening.

● It’s official: Oubre will miss Game 4 on Sunday night after being suspended by the NBA on Saturday afternoon. Oubre, ejected from Game 3 for charging at Boston’s Kelly Olynyk and leveling him with a shove after taking offense to a high, hard screen, took the punishment in stride, saying he was concerned about the possibility of a suspension almost immediately after leaving the floor, but added “it happened, [the league] made it their rule and I have to follow it.”

● John Wall has always been viral, writes Dan Steinberg. Thursday night, Wall scowled and danced and kept the gif-makers engaged throughout Washington’s blowout win over the Celtics, which got Washington back into this second-round series. Wall has left little doubt that he is now the (scowling) face of D.C. sports.

● By the time the Wizards gathered for practice Friday afternoon, gone was the agitated, sputtering Oubre who needed to be held back by teammates as he strained his neck and head toward Boston’s Olynyk and jerked his arms forward in a punching motion during the second quarter of Game 3. The Wizards’ young forward said he’d learned his lesson, while offering no excuses for the play that got him run on Thursday night.

● Desperate after losing two games in Boston that they could have won, the Wizards made sure the Celtics couldn’t rally in Game 3. How did they do it? They pushed back, Jerry Brewer writes. They didn’t whine about how physical the Celtics were in the first two games. They just competed harder, and in doing so, they took the series to another level of ruggedness.

● Wizards contain Isaiah Thomas on offense by making him play defense, Boston’s dynamic point guard finished with 13 points on 3-for-8 shooting, missing both of his three-point attempts, for his lowest scoring performance of the Eastern Conference semifinals.

● Olynyk clobbered Oubre on a screen and the Wizards forward popped right back up  and shoved Olynyk to the ground, running into a ref along the way. The young Wizards forward was immediately ejected from the game, bringing the tensions between the two teams to a boil.

● The Wizards spent the first two games of these Eastern Conference semifinals building leads and losing them. In Thursday’s Game 3, they set a physical tone early, built another big lead and maintained the edge en route to a 116-89 win.

● Wall has felt ignored by officials whenever he aggressively drives to the rim. This has been his season-long gripe that naturally has carried over to the rough-and-tumble playoff series against the  Celtics. While this is nothing new, on Thursday Wall revealed for the first time that he views himself similarly to LeBron James in this aspect.

● Isaiah Thomas’s illegal free throw shooting form has been the subject of multiple Reddit threads this season, including one titled, “Why are we ignoring how Isaiah Thomas cheats on every free throw?” Tweets about Thomas stepping over the line, which he does on most, but not all, of his attempts, seem to have increased in frequency during the playoffs. “To me, it doesn’t help him, but is it a violation? Yeah, it is,” said Steve Javie, a longtime NBA referee who now does analysis for ESPN.

● Oh no they di’int! Oh yes they did. Twenty-three years after the Bullets released one of the great team-produced rap videos of all-time, Monumental Sports Network dropped a reboot of “You Da Man” ahead of Game 3 of the Wizards’ second-round series against the Celtics. It is fantastic.

● The comeback defines this Wizards season. For some reason, they perform best when chasing. During the regular season, the Wizards won 17 games after trailing by double figures. They’re the only team in NBA history to win at least 49 games after starting with a 2-8 record. As the first two games against Boston and, really, the entire playoffs have shown, they know how to blow leads, too. They live and die by the comeback. Down two games, the Wizards have struck desperation again, which is a strangely comfortable state for them, writes Jerry Brewer.

● Scott Brooks is taking the heat. The Wizards coach shouldered responsibility for digging out of the 2-0 hole. When questioned about pivotal moments of the 129-119 overtime loss in Game 2, as well as poor individual performances, Brooks accepted blame.

● Doesn’t it sometimes look like Isaiah Thomas has a bit of Kobe Bryant in him? There’s a reason for that. “He made me figure out a lot of things,” Thomas said of Bryant to reporters. “He’s just been a very helping hand when it comes to the film and figuring out what to do the next day.”

● In Game 2 of the Eastern Conference semifinals, this best-of-seven matchup rose from a mellow first game and provided the thrills and strain to justify the anticipation, writes Jerry Brewer. This was a bloody good game, literally, the perfect combination of brutal and appealing. It was painful to watch. It was beautiful to watch.

● If this past week has felt particularly exhausting and exhilarating, abusive and absurd, there’s a rational explanation, writes Dan Steinberg. We’re currently in the middle of a nine-day stretch in which either the Wizards or Capitals will play a postseason game every day. That has never before happened this late in the season, not in this town. It’s a foolish marathon none of us has ever attempted, and we’re running it without knowing whether finishers will receive laurel wreaths or whoopee cushions.

● Markieff Morris played — and played well Tuesday. In fact, Morris’s night started so well in Boston, the injured Wizards forward’s game spawned conspiracy theories that he had swapped places with his pro basketball playing, identical twin brother, Marcus. He scored 16 points on 6-for-11 shooting, pulled down six rebounds and dished out three assists.

● In a Game 2 duel featuring two all-star guards, Washington’s John Wall performed as a singular force with 40 points and 13 assists, but Isaiah Thomas shined brightest by scoring 53, the second-highest point total for an individual in Boston’s storied playoff history. Here are the best and worst moments from the Wizards’ loss.

● An offensive outburst by Boston in Game 1 is the result of a craftily designed plan by Coach Brad Stevens, one hatched in Game 3 of the Celtics’ series against the Chicago Bulls. By swapping in Gerald Green or Marcus Smart for the struggling Amir Johnson, Boston gains speed and versatility at the expense of size. And they’ve been gaining wins as a result.

● For different reasons, the Wizards and Celtics exemplify the merits of patient team building, writes Jerry Brewer. They won’t be celebrated for it, however. Patience is a sin to the passionate.

● The 6-foot-11, 240-pound center with a tattoo of a hammer on his left biceps is not fragile. Not only is Marcin Gortat not fragile by nature, but right now, he cannot afford to be fragile. Not with the Wizards’ roster of big men as battered as they are. Gortat twisted his ankle slightly in Game 1, but there will be no sitting out for the starting center.

● Even if Markieff Morris makes a quick recovery and plays in Game 2, the Boston matchup should force the Wizards to play small for stretches. That means possibly more Otto Porter and Kelly Oubre Jr. on the floor together, but Sunday’s third quarter showed that the Wizards will need more than just “energy” out of their forwards.

● The Wizards are a very good, very talented team. But like all very good, very talented teams, they still have bad habits. And sometimes, those bad habits supersede all of their talent. Such was the case on Sunday during Game 1 in Boston, when Washington raced out to a 16-0 lead only to see the Celtics not only climb back into it, but use a third quarter as dominant as the Wizards were in those opening moments to ultimately come out on top. As Jerry Brewer writes, “Some might consider it a ridiculous way to lose. For the Wizards, it’s just typical. And that’s the problem.”

● That hot start was the Wizards running on all cylinders. But the momentum started to shift before the end of the first quarter. And then, as if Washington didn’t already have enough to worry about concerning its frontcourt depth, Markieff Morris badly turned his ankle and was forced to the locker room. He wasn’t able to return, and when the Wizards lost Morris, they essentially lost the game as well.

● Boston’s Isaiah Thomas has been through a lot since the start of the playoffs. He learned that his younger sister, Chyna, was killed in a car accident on the eve of the Celtics’ first-round series with the Chicago Bulls. He played in every game of that matchup, though, so it was no surprise to see him back on the TD Garden court at the start of Sunday’s contest despite attending Chyna’s funeral in Tacoma, Wash., on Saturday. In the first quarter, Thomas lost a front tooth when he caught an elbow from Otto Porter trying to get around a pick. But as his 33 points, five three-pointers and just two turnovers will attest, his game was anything but toothless.

● Among the many story lines percolating within this Eastern Conference semifinal stands the matchup between two of the NBA’s best point guards. John Wall and Isaiah Thomas are not only the most valuable players on their respective teams, they’re fringe-y MVP candidates for the entire league, and while neither of them will win that award, this series will shine a bright light on each of them. Wall, for his part, is getting an “opportunity to show the world” what he’s truly capable of doing, beginning Sunday afternoon in Boston.

● The Wizards advanced on Friday night on the stellar play of John Wall, who scored 42 points against the Hawks in Game 6. If there was any doubt about Wall’s status as a superstar in the NBA, there is none left, writes Post columnist Jerry Brewer. In the fourth, he scored 19 points on 7-for-10 shooting. And he added a signature and very Wall flurry when his team needed him most.

● From 2013-15, Andre Miller spent 79 games teaching younger players within the Wizards’ locker room. Those kids — Bradley Beal and John Wall — are now the team’s top dogs, and during Washington’s first-round series against the Hawks, the former player, nicknamed “the Professor,” marveled at the growth displayed by the two star guards. “They’re on the job and learning a lot and they’re healthy. They’re leaders. They’re doing a great job,” Miller said.

● Wall never forgets. And two years removed from an apparent slight on Instagram by Atlanta’s Dennis Schroder, the Wizards superstar got his sweet, sweet revenge. How long can one man dream about posting an Instagram rejoinder? Apparently at least two years.

● Phil Chenier isn’t done in the booth, but the Bullets great and CSN color analyst won’t be the same fixture during Wizards games as he has in the past. Chenier and play-by-play man Steve Buckhantz had their final ride Friday night during Game 6, and he left fans watching with a “Dagger!” call and his booth partner with a kiss.
