Here is Dayn's blurb on Bartolo in his AL West preveiw.
8. When will Bartolo Colon be back?
Los Angeles/Anaheim/O.C. ace Bartolo Colon missed most of the second half of 2006 with a torn rotator cuff, and he's still recovering from surgery. At first, it appeared that Colon might miss most of the upcoming season, but now the organization believes he'll be back in advance of the All-Star break. Colon himself insists he might be ready for opening day. While that seems highly unlikely, it does suggest he's ahead of schedule. Whenever he returns, Colon needs to be effective so he can relieve the pressure placed upon young arms like Jered Weaver and Joe Saunders and on injury-prone hurlers like Kelvim Escobar.
Last time I checked he went the rehab route - - what an asshat this guy is. How does he get paid to write?
