Cole Irvin started for Baltimore, giving up five runs on seven hits and three walks in five innings. He struck out four.

Triston Casas hit a two-run homer to give the Red Sox a 5-0 lead in the fifth.

The Orioles scored three times in the sixth, with four consecutive hits off reliever Isaiah Campbell to open the inning. Holliday snapped the streak with a groundout that drove in a run.

Baltimore added four runs in the seventh off Chris Martin (1-1), including Westburg’s three-run shot that gave the Orioles a 7-5 lead. It was his second homer of the season.

Mike Baumann (1-0) struck out three in a scoreless inning and Craig Kimbrel fanned two in the ninth for his second save.
