The Boston Red Sox have been relatively inactive at the trade deadline compared to other contending teams. The latest rumor from Francys Romero suggests that may change soon.
Romero reports that the Red Sox have been in contact with the Arizona Diamondbacks about pitcher Merrill Kelly. Kelly is on an expiring contract and would be a true rental, which chief baseball officer Craig Breslow initially hoped to avoid. Teams selling controllable starters have requested astronomical returns, so Kelly may be the best option for Boston in the tight American League, despite Breslow's previous desires.
Kelly is possibly the best rental pitcher available on the market this year.
