Jason Hammel gave up a career-high four homers to the Toronto Blue Jays, and it was their aggressive swings on his breaking balls that left the right-hander asking questions.

Jason Hammel had given up three home runs in nine starts before giving up four to the Blue Jays on Wednesday.

Edwin Encarnacion hit one of Toronto’s four solo home runs, pitcher Brandon Morrow left the game after being struck by a line drive and the Blue Jays beat the Baltimore Orioles 4-1 Wednesday night to complete a three-game sweep.

Hammel (6-2) lost for the first time since April 30 at the New York Yankees. He gave up four runs and a season-high nine hits in 6 ? innings, walked two and struck out five.

“When you’re not locating your fastball, you’re going to give up some home runs there,” Hammel said. “But the swings they were taking on the breaking stuff, it was pretty amazing to me. I don’t think you can take swings like that not knowing they’re coming. I don’t know. That’s all I can say.”

The Blue Jays were featured in an ESPN report in August that accused the team of using a man dressed in white in the centre-field seats to relay information to hitters. Weeks earlier, Yankees manager Joe Girardi accused the Blue Jays of stealing signs during a visit to Toronto.

Hammel acknowledged being aware of the prior accusations.

“There’s rumours and things like that,” he said. “I don’t know. I can’t speak on that, but they were taking very big, strong hacks on breaking stuff. It’s something I’ve never seen before.”
