Baltimore has lost seven of its eight home games.
Irvin (2-2) had won back-to-back starts just once before, his first two career starts for Philadelphia in May 2019. Coming off six shutout innings against Detroit on Saturday, he stymied the Orioles for five innings. But Baltimore stitched together four singles in the sixth, capped by Pedro Severino’s RBI single, to end Irvin’s night.
Jake Diekman worked the ninth to earn his second save in as many tries.
Jorge López (1-3) was the loser.
