Cardinals acquired RHP Justin Masterson from the Indians in exchange for OF James Ramsey. Masterson has struggled in his walk season, posting a 5.51 ERA over 19 starts. However, he's dealt with a knee issue and the Cards are hopeful that he'll pick things up if that injury is behind him. He should also certainly benefit from a move to the National League. Masterson will make his Cardinals' debut on Saturday against the Brewers.
