BOSTON -- After sitting through a home opener ceremony for the third time this season, Baltimore was more than happy to play the role of spoiler at Fenway Park on Tuesday, beating the Red Sox, 7-1, behind the efforts of Colton Cowser and Corbin Burnes.

In his third start for the O’s, and his first career start in Boston, Burnes gave up a solo home run over the Green Monster to Tyler O’Neill in the bottom of the first followed by a single off the bat of Triston Casas. After that, the 2021 National League Cy Young Award winner cruised, allowing just two walks and no hits over the next six innings.

“That was really good,” manager Brandon Hyde said. “It was kind of a tough start for him there, he hung a breaking ball to O’Neill, but besides that, he gave up two hits through seven innings. He was in total command, pitching in a tight game. He punched out a bunch. That’s number one starter stuff right there.”

The Orioles weren’t down for long, as they evened the score in the top half of the second inning when Cedric Mullins came around on a Cowser double.

Baltimore took advantage of some sloppy fielding by the Red Sox to take the lead in the fourth inning. After the first two batters were retired, Ryan Mountcastle reached on a hot shot to third that third baseman Rafael Devers couldn't corral.

Cedric Mullins was up next, and he sent a routine fly ball into left field, but Jarren Duran lost the ball in the sun, and the Orioles found themselves with runners on second and third with two outs. Cowser came through again, this time lacing a double into left-center field to score both runners and give Baltimore a 3-1 lead.

Cowser was 2-for-4 with a sac fly on the day, driving in four runs for the first multi-RBI game of his career. In the process, he became the youngest Orioles player (24 years, 20 days) with two doubles and four RBIs in a game since Cal Ripken Jr. (23 years, 10 days) on Sept. 3, 1983, at Minnesota.

“Big hits for us there early in the game,” said Hyde of Cowser’s efforts. “He played really well. That was a great addition today.”

“As a whole, I think it was a great team win,” noted Cowser.

Burnes admitted that it took him a bit longer into the game than usual to find his groove, but with the help of Adley Rutschman, they were able to maintain until he found it.

“It took me until about the third inning to feel comfortable out there,” Burnes said. “For whatever reason, the first two innings, command wasn’t right, didn’t really spin the ball good. The third inning we kind of locked it in, started mixing a little better, got them off balance, started to get the punchouts late. … Adley did a great job behind the plate, mixing it up.”

The Orioles’ starter retired the last 12 batters he faced and finished his seven-inning outing with six strikeouts, earning his second win of the year and lowering his ERA to 1.93.

“It was good to get through seven,” said Burnes. “It was good to get a win.”
