"You know what? I'm not used to seeing that," Gaston said. "They didn't beat him up badly. I think he just didn't locate the way he wanted to, and when you don't, you're going to get hit sometimes."

Jeff Bailey went deep in the second, Jed Lowrie homered in the third and Chris Carter connected in the fifth against Halladay, whose nine-inning scoreless streak ended when Lowrie doubled in a run in the first.

"Most of the fastballs, both sinker and cutter, I left quite a few over the middle," said Halladay, who was 20-11 with a 2.78 ERA last season. "Especially, I was trying to go away and brought a lot of them back over the plate."

Justin Masterson pitched three-plus innings for Boston, allowing three runs and six hits.

Red Sox manager Terry Francona said Masterson "had good velocity. A couple of left-handers got into fastball counts and they hit it. He'll come back in his next rotation and start again. By then we'll be pretty deep in camp."

Travis Snider hit his third home run for Toronto.

NOTES: Jays optioned pitchers Robert Ray, Bill Murphy and Davis Romero to Triple-A Las Vegas, optioned pitcher Matt Bush and Luis Perez to Class A Dunedin.
