Given their roster makeup, the Indians can afford to keep Andy Marte with the major-league club, but he'll make it in a reserve role:
After hitting .275/.372/.506 in AAA at the age of 21, Marte's regressed the past two seasons. Injuries and a couple of poor major-league stints makes this season extremely important both for Marte and the Indians. He's only 24 years old, and current third baseman Casey Blake is only signed through this season, so Andy remains the long-term solution at the hot corner. But he'll have to win the job playing only sporadically. And third base is really his only opportunity to play, since the Indians aren't going to want to sit Ryan Garko or Victor Martinez that often.
Shin-Soo Choo, who is also out of options, won't be able to play in the field until May, though he's hitting now. Like third base, left field isn't a settled position, so I would imagine the Indians will make sure Choo's rehab is very thorough, if you know what I mean.
Eric Wedge will go with seven pitchers in the bullpen:
Whoever loses out shouldn't feel that disappointed, for bullpens almost never keep the same configuration over the course of a season, let alone a month. I'm partial to Edward Mujica over the long haul, but Mastny seems to be a better fit for long relief.
