The two-time Cy Young Award winner made the announcement before the Phillies played the San Francisco Giants on Wednesday. He says "I have a good chance to come back and pitch this year, hopefully be a lot more effective." On the 15-day disabled list because of inflammation in his throwing shoulder, Halladay is 2-4 with an 8.65 ERA in seven starts this season after missing nearly two months last year because of a strained back muscle.
