Stinson did not pitch particularly well, as he surrendered four home runs in 5.2 innings. The right-handed only allowed five runs despite the four homers, striking out three while walking one in the 76-pitch effort. Stinson did not factor into the decision, but the Orioles ended up losing 6-5 in 11 innings.
The 25 year-old pitcher has bounced around the league in his short career. He made three apperances for the New York Mets out of the bullpen in 2011, then made a start for the Milwaukee Brewers last season. The Orioles picked Stinson up from the Oakland Athletics on a waiver claim earlier this season.
Stinson is a pitch-to-contact style thrower who survives on forcing groundballs and keeping the ball in the ballpark. That makes Toronto's four home-runs hit against him particularly problematic, and the issue will need to be resolved before he makes his next appearance in the major leagues.
The Orioles will announce a corresponding roster move tomorrow. The team is expected to recall an extra arm for the bullpen, which threw 5.1 innings on Wednesday and 34 innings during the nine-game homestand.
