Phillies pitcher Sean O'Sullivan surrendered four earned runs on five hits and four walks in four innings while striking out two and fiving up two home runs in his team's 10-6 loss to the Blue Jays.

"It didn't quite go as well as I would have liked it," O'Sullivan said after the outing, per MLB.com. "I felt a little off on my release points. That's mostly because I've only been on the mound once in the last 11 days."

O'Sullivan is the favorite to serve as the team's fifth starter but didn't help his candidacy Tuesday, as his spring ERA rose from 6.75 to 7.59 after the mediocre showing. He ends Grapefruit League action with an 8:5 K:BB ratio and four home runs allowed in 10 2/3 innings.
