Roy Halladay could miss up to eight weeks this summer because of a shoulder issue, which could eventually lead to him hitting the free agency earlier than expected. Halladay signed a three-year, $60 million deal before 2010 with a $20 million vesting option for 2014 that automatically activates if three conditions are met: 1. He throws at least 225 innings in 2013. 2. He isn't on the disabled list at the end of 2013. 3. He throws at least 415 innings total in 2012 and 2013. If Halladay misses eight weeks this season, reaching No. 3 would be very difficult for the right-hander.
