Last summer, with a middle-infield prospect crunch, Breslow traded infielder Nick Yorke to Pittsburgh for starter Quinn Priester, whom he then traded to Milwaukee for an outfield prospect and a draft pick after the first round, which the Red Sox used to net right-hander Marcus Phillips this year.

Marcelo Mayer's injury is leading to a lot of moving parts for the Red Sox. It could also impact how Craig Breslow approaches next week's trade deadline.

The Boston Red Sox are named by MLB insiders as a potential landing spot for former aces Sandy Alcantara and Zac Gallen at the trade deadline.

The Sox throttled Cubs ace Shota Imanaga and homered four times to grab their sixth win in seven games, a stretch in which they've scored 61 runs.
