Montero allowed five runs on seven hits and a walk across 4.2 innings of work in Friday's 7-1 loss to the Orioles. He struck out seven.
Montero followed opener Tyler Holton, who allowed two runs of his own, so the former wasn't charged with the loss. However, Montero still struggled as he gave up four home runs and saw his ERA climb from 4.60 to 4.86. The silver lining was the seven strikeouts, which were one away from matching a season high. Montero was previously penciled in to start Sunday's contest against Baltimore, but the team will likely go in a different direction after the righty tossed 82 pitches on Friday. Montero would then likely start or serve as a bulk pitcher sometime next week.
