Some teams can relax because their 2011 rotations are more or less set, but that's not the case for every club. That's why the nine teams below will be eyeing the starters that become available through trades and free agency. They'll either have to re-sign their own free agents or acquire a starter if they'd prefer not to rely on younger in-house options.
- Yankees – Javier Vazquez and Andy Pettitte hit free agency.
- Tigers – Jeremy Bonderman is a free agent (Detroit could hand Andy Oliver a starting job).
- Mariners – Erik Bedard (mutual option) and Ian Snell (club option) are likely gone and the M's may want rotation depth.
- Brewers – Dave Bush and Doug Davis (mutual option) are eligible for free agency.
- Cardinals – Are the Cards going to enter next season with Kyle Lohse and an inexperienced starter at the back of the rotation? They'll presumably keep an eye out for cheap rotation candidates.
- Dodgers – Ted Lilly, Hiroki Kuroda and Vicente Padilla hit free agency.
- Rockies – Jeff Francis (club option) and Jorge de la Rosa could hit free agency.
- Diamondbacks – Rodrigo Lopez hits free agency.
- Padres – Jon Garland (mutual option), Kevin Correia and Chris Young (club option) may hit free agency.
