Blue Jays ace Roy Halladay left his start against visiting Florida after apparently injuring his groin.
Halladay grimaced after throwing his second pitch in the third inning last night. Catcher Rod Barajas went to the mound, then motioned to the dugout, calling manager Cito Gaston and trainer George Poulis to join him.
Toronto's infielders huddled on the mound as Halladay spoke with Gaston and Poulis. Halladay threw one warm-up pitch, then flipped the ball to Barajas and headed to the dugout.
The Jays said Halladay tweaked a muscle in his right groin.
Halladay, whose next scheduled start is Wednesday against the Phillies, leads the major leagues with 10 wins and 103 innings pitched. He has won seven straight decisions and entered last night's game having thrown back-to-back complete games.
Cody Ross hit a tiebreaking grand slam, Chris Coghlan had a career-high four hits and the Marlins went on to beat the Blue Jays, 7-3.
