OAKLAND, Calif. — There would be no opportunities for another late-game reversal Saturday night in Oakland — the Orioles made sure of that before their first chance to bat was through.

In their 12-5 win over the Oakland Athletics at Oakland Coliseum, the Orioles sent 11 men to bat in the first inning and nine of the first 10 reached base as they scored seven runs. That big inning was all right-hander Dylan Bundy needed to improve himself to 12-8 on the season, and the Orioles back to just a game below .500 at 58-59.

Their 20 hits tied a season-high, and their eight doubles were their most of the season.

The list of offensive standouts was long, and all parties got involved in the seven-run first inning. Shortstop Tim Beckham’s leadoff walk was the first of five times he reached base, and he scored from first on a double by third baseman Manny Machado. Center fielder Adam Jones’ double scored Machado and provided the first of his three RBIs, a count that could have been higher had second baseman Jonathan Schoop not been thrown out at home on the play.

Rookie designated hitter Trey Mancini singled to score Jones, and after a double by Mark Trumbo moved him to third, first baseman Chris Davis singled to drive in the Orioles’ fourth run. That chased Oakland starter Sean Manaea, whose only out came courtesy of Schoop on the base paths. Michael Brady allowed another run when catcher Welington Castillo grounded into a forceout, and two more scored when Beckham doubled to left field.

All told, it was the Orioles’ first seven-run first inning since May 20, 2005 against the New York Yankees, according to STATS, LLC.

Bundy backed up his first career 10-strikeout game on Monday with another one Saturday, fanning the last two batters he faced to give him 10 again and complete his 16th quality start in 23 tries.

His 17 swinging strikes — 11 of which came on his slider, according to Baseball Savant — tied a career high for the 24-year-old right-hander, whose ERA is now 4.17 on the season after he allowed three runs on seven hits with three walks.

Most of the damage came early, as he walked leadoff man Boog Powell and saw him score on a home run to left fielder Khris Davis in the first inning, and allowed a leadoff home run to first baseman Matt Olson in the second inning.

Oakland’s other two runs came off reliever Miguel Castro in the eighth inning.

After their explosive first inning, the Orioles only put runs across again in the fourth and ninth innings. Brady hit left fielder Joey Rickard to open the fourth and allowed another double to Beckham before a two-out single by Jones.

Jones also singled in the eighth inning to make him 8 for 13 with a pair of home runs and seven RBIs since the Orioles re-installed him as the cleanup hitter when they arrived in Oakland, raising his average to .273.

Craig Gentry came off the bench to double in the ninth, and scored on a single by first baseman Chris Davis. Davis had two RBIs and reached three times in the win.

Beckham’s eye-popping start for the Orioles continued when he reached base in his first four plate appearances and five of six overall Saturday, scoring three times and driving in three to give him nine RBIs and 14 runs scored with the Orioles.

He has 12 extra-base hits in 12 games, and ended the day hitting .531 since joining the Orioles on July 31.
