A.J. Burnett laboured through four innings as the Toronto Blue Jays lost 4-1 to the Pittsburgh Pirates in a Grapefruit League matinee at Bradenton, Fla., on Monday.

Burnett surrendered four runs on four hits and four walks, and failed to register a strikeout.

Jason Bay of Trail, B.C., reigning National League batting champion Freddy Sanchez and Nate McLouth each had a run batted in for the Pirates (7-12).

Pittsburgh starter Zach Duke scattered three hits over five scoreless innings, tossing just 51 pitches.

Reed Johnson drove in Toronto's only run with a ninth-inning sacrifice fly off reliever Evan Meek.

Lyle Overbay had the only extra-base hit for the Blue Jays (7-12), stroking a leadoff double in the sixth inning.

Toronto finished with five hits overall.

Closer B.J. Ryan threw a scoreless inning, allowing one hit and striking out one batter in his second appearance this spring.

"I was sore and did not feel as sharp as I was my first time out," he said. "But I made some good pitches and battled through it and put up a zero."

Ryan pitched in five games last season before having season-ending left elbow surgery.
