The Orioles’ game Sunday against the Atlanta Braves was the earliest they’ll play this season.

Baltimore’s bats never woke up.

The Braves ended the Orioles’ streak of seven straight series victories as Michael Harris hit a walk-off double off reliever Cionel Pérez in the 12th inning of a nationally televised game that started at 11:37 a.m.

Baltimore’s lineup managed just five hits in 40 at-bats and went 1-for-14 with runners in scoring position, offensive futility that spoiled nine stellar innings from its pitching staff and sent the game to extra innings.

The Orioles (22-12) took a one-run lead in the 10th on Anthony Santander’s double, but closer Félix Bautista allowed the automatic runner to score in the bottom half to blow his second save of the season. But the lineup stumbled in the 11th and 12th, failing to score the automatic runner in either frame.

Mike Baumann bailed out the club’s bats in the 11th by tossing a scoreless inning, but Pérez couldn’t replicate Baumann’s heroics.

Harris’ double was the Braves’ first hit since the fifth inning, as the Orioles’ bullpen had gone 6 1/3 innings without allowing a hit before Pérez gave up the walk-off hit.

Tyler Wells has started six games this season. He’s given the Orioles a chance to win in all six.

Wells wasn’t efficient Sunday, but he allowed only one run in five innings. He scattered three hits and one walk while striking out four on 96 pitches.

The right-hander gave up a solo home run to slugger Matt Olson in the first inning, as Wells left a fastball over the plate that the first baseman blasted 413 feet to center field. Wells didn’t allow a batter to reach safely until there were two outs in the fourth. From there, the 28-year-old had to battle to record his next four outs and keep the game tied.

After Eddie Rosario’s single, Wells walked Marcell Ozuna and then gave up a 406-foot fly ball to Harris that was caught by center fielder Cedric Mullins at the wall in center field. The batted ball would be a home run in 14 of 30 MLB ballparks, according to Statcast, but not at Truist Park.

Orlando Arcia led off the fifth with a double, but Wells retired the next three batters to strand another runner.

Through the first fifth of the season, Wells has been Baltimore’s best starting pitcher with a 3.15 ERA and a 0.78 WHIP. No other Orioles starting pitcher has an ERA under 4.60 or a WHIP under 1.34.
