Toronto's Ricardo Nanita started the rally with a leadoff single off Baltimore reliever Pedro Strop, and Nanita advanced to second base when Strop unleashed a wild pitch to the next batter, Yan Gomes. After Gomes singled to push Nanita to third, David Cooper walked, and the bases were full.
Nanita came home, tying the score, on Jonathan Diaz's sacrifice fly, which allowed both Gomes and Cooper to advance a base. Strop's wildness came back to hurt him again, committing a throwing error on a ball hit by Andrew Gose, allowing Gomes to score and Cooper to reach third.
That was all for Strop, who was replaced by Stuart Pomeranz, who quickly recorded the second out of the inning. But the Blue Jays weren't done scoring, as Brian Bocock singled to plate Cooper and Gose.
The rally ended there, as Pomeranz got Chris Woodward to fly out and bring the top half of the inning to a close.
Orioles starter Tommy Hunter went five innings in his Grapefruit League debut, allowing two runs on five hits and a pair of walks. Hunter -- who has been slowed this spring by discomfort in his lower back -- had no problems in the 74-pitch outing, picking up a pair of strikeouts along the way.
Toronto righty Kyle Drabek, who is in contention for the fifth starter spot, allowed two runs on three hits and two walks over 3 1/3 innings in his fourth spring outing. He also struck out three before being replaced by Luis Perez, who tossed 1 2/3 innings of scoreless relief.
Blue Jays catcher J.P. Arencibia hit his fourth homer of the spring, connecting on a 2-0 offering from Hunter in the third inning, and Omar Vizquel had two hits, including a double. Orioles outfielder Endy Chavez reached base safely in all three of his at-bats and scored twice.
Up next for the Blue Jays: Right-hander Brandon Morrow will make his fourth start of the spring when the Blue Jays host the Phillies on Thursday at 1:05 p.m. ET at Florida Auto Exchange Stadium. Morrow is scheduled to throw five innings, and he enters the game having surrendered just one earned run in 7 1/3 innings of Grapefruit League work. He will be followed on the mound by Carlos Villanueva, Darren Oliver and Jason Frasor. Brett Lawrie likely won't play until Saturday because of tightness in his left groin.
