"Halladay grimaced after tossing his second pitch of the inning. After manager Cito Gaston and trainer George Poulis visited the mound to talk to him, Halladay tried one warm-up pitch, then tossed the ball to catcher Rod Barajas and left for the dugout. More news as it becomes available. Hopefully it's nothing serious and the Jays erred on the side of caution."
