Kyle Schwarber crushed the fourth pitch of the game into the stands, and it was clear from then on what type of game it would be Friday night at Camden Yards.

No, not a high-scoring one, despite the matchup featuring baseball’s two best offenses. It was a playoff-caliber game — from the elite starting pitchers to the star hitters to the sold-out crowd — with twists and turns, clutch hits and an extra-inning rain delay to boot.

From the moment Schwarber’s 406-foot blast carried over the fence, and the significant portion of Philadelphia Phillies fans showered Oriole Park in cheers, it was clear this was no regular-season game — no matter what the schedule or standings say.

But that wasn’t the biggest hit from a Phillies batter on the night.

After a 1-hour, 11-minute rain delay before the 11th inning thinned the raucous announced crowd of 43,987 to roughly one-third of that, Phillies cleanup hitter Alec Bohm’s tiebreaking two-run double and the Orioles offense’s inability to come through in the clutch in the bottom half handed Baltimore a 5-3 loss. The Orioles went 1-for-13 with runners in scoring position and left 10 on base.

Anthony Santander’s game-tying solo homer in the eighth breathed life into a lineup lumbering with the lumber. But it couldn’t manage a hit in the final three innings against the Phillies’ bullpen.

The Orioles’ bullpen nearly escaped the 10th inning without surrendering a run, aided by second baseman Jorge Mateo throwing Bryson Stott out at the plate on a grounder. But Yennier Cano allowed two base runners, and southpaw Cionel Pérez allowed a left-on-left single to Schwarber, allowing one of Cano’s runners to score. Santander nabbed Johan Rojas trying to score, keeping the Orioles’ deficit at one run.

Down to the Orioles’ last out, Gunnar Henderson walked to load the bases, and Mullins raced home to score on Phillies reliever Orion Kerkering’s wild pitch. He was originally called out, but the replay review clearly showed Mullins touched home before catcher Rafael Marchán’s tag. Seconds later, rain poured in Baltimore, delaying one of the Orioles’ most exciting games of the year.

Baltimore is 45-24 and has lost its past two after winning six straight.
