The Indians could be without 28-year old righty starting pitcher Justin Masterson for the rest of the season due to an oblique injury. If Masterson is out for the rest of the season, it will be a major blow to the Tribe as they try to make the playoffs. They are currently 3 games behind the Tampa Bay Rays for the second Wild Card spot. Masterson has pitched in 29 games (all starts) for the Indians so far this year and he is 14-10 with a 3.52 ERA and a 1.22 WHIP. He has thrown three complete game shutouts this year, as he has been the workhorse of the rotation so far in 2013. Masterson has given up only 155 hits and 75 walks while whiffing 188 batters in his first 189 1/3 innings this year, which are pretty impressive numbers. Masterson has now pitched in 142 games (135 starts) in his first five years with the Indians and he is 44-55 with a 4.10 ERA and a 1.38 WHIP.
