Friday had already started off in a festive way for Khalil Lee. That morning, the Flint Hill senior walked across the stage and graduated in his cap and gown before heading to Tyson's Corner to celebrate over a meal with his family.

The occasion allowed Lee to briefly shift his focus from the one thought that had dominated his mind during the previous weeks: the MLB draft. That is, until his phone range in the middle of brunch.

An adviser from the Kansas City Royals, the same team Lee had flown out to work out for the previous week, was on the other end, alerting the outfielder that the Royals planned to select him in the third round with the No. 103 overall pick.

After getting off the phone, Lee pulled up the MLB draft livestream on his phone to watch his dream come true — in the same year that Lee earned All-Met honors and the Virginia Gatorade Player of the Year and on the same day he received his high school diploma, Lee had become a Major League Baseball player. He was the second of six prep players from the Washington area to be selected in the 40-round draft this past weekend.

A day later, Lee signed with the Royals for undisclosed terms, and on Monday, he flew out to Arizona, where he will compete in the rookie-level Arizona League. Though Lee elevated his draft stock this spring by excelling at the plate (.471 batting average, six home runs, 37 runs, 23 RBI) and on the mound (7-0, 0.33 ERA, 87 strikeouts), he said he will focus on his natural position of outfielder at the pro level.

"I'm ready to take my physical exam, get to work and doing whatever it takes to get better and ready to play," said Lee, who was committed to play at Liberty. "I want to help my team and make my mark any way that I can."

A day before Lee was selected, Oakton's Joe Rizzo was snatched up by the Seattle Mariners with the 50th overall pick. Lauded for his powerful swing, Rizzo did not last past the draft's first day, as most had expected. While Lee signed immediately, Rizzo's negotiation process will take a bit longer, as he and Seattle sort out how to dole out the $1.252 million slotted for his draft position.

In the meantime, Rizzo, who batted .606 with seven home runs as a junior and .392 with four home runs this spring, spent his Saturday taking in the Virginia 6A state final at Robinson in Fairfax. There, the South Carolina commit told The Post he had an idea that Seattle would draft him, after the organization contacted his adviser Wednesday to say it would take the slugger with the 50th pick if he was still available.

"It feels good and exciting to be picked that high," Rizzo said. "The next steps from here depend on the contract negotiations, but I'll more than likely be moving in the direction of going pro."

A quartet of other area high school standouts heard their names called over the weekend. West Potomac two-sport standout Jamie Sara was snagged in the 12th round by the San Diego Padres. Sara, who earned all-region honors in basketball and baseball, is the first West Potomac player picked straight out of high school and is committed to play at William & Mary.

And finally, the Washington Nationals took two Maryland-based prep standouts in the final two rounds. Georgetown Prep third baseman-pitcher Matt Mervis, who signed with Duke, was picked in the 39th round, and Whitman pitcher Sean Cook went in the 40th.
