Marcum said he “absolutely” considered retaliating, but didn’t want to risk a suspension.
“I guess that’s how they do things over there,” Marcum said. “I think we have a little more respect for the game and respect for players on other teams. We’re not going to throw at them on purpose, even if they have 50-plus homers. It is part of baseball, I understand you have to pitch people inside, but to bring a guy in from the bullpen and throw two pitches at him and then get ejected, it seemed like it was very intentional.”
The loss was the fourth straight for the Orioles, their longest skid since Showalter took over as manager in early August.
Toronto went 15-3 overall against the Orioles this year, outscoring them 93-51 and outhomering them 34-8.
Marcum (13-8) pitched seven innings and set a career high for victories, completing this three-game sweep. He allowed one unearned run and struck out seven while improving to 3-0 with an 1.13 ERA in four starts against Baltimore this season.
The righty missed all of 2009 after elbow ligament replacement surgery in Sept. 2008.
“Missing last season obviously was unfortunate,” Marcum said, “but to be back here and have one start left and to finish the whole season without going under the knife again is a pretty good feeling.”
Shawn Camp got two outs in the Baltimore eighth but was lifted after Adam Jones hit an RBI single. Jason Frasor struck out Matt Wieters to end the inning, then finished in the ninth for his fourth save in seven chances.
John McDonald drove in three runs and Adam Lind had three hits for Toronto.
Notes: Blue Jays SS Yunel Escobar was held out of the lineup with McDonald starting in his place. … The Orioles are 98-144 all-time in Toronto. … The Blue Jays failed to homer for the first time in 14 home games.
