The Red Sox rotation ranks 21st in baseball in ERA. With Kutter Crawford and Tanner Houck progressing and two rookies piggybacking, tough decisions may loom for Craig Breslow.

The Red Sox face a make-or-break June, and if things don’t turn around the club could potentially sell aggressively at the trade deadline.

Fitts tossed three scoreless innings Tuesday against the Brewers, allowing two hits and a walk while striking out two. Fitts tossed just 44 pitches over three innings, as it was expected to be a short outing for the 25-year-old in his return from a pectoral strain.

The next big starting pitcher is Chase Burns, but the fantasy market will have to wait for him to be called up.

As Richard Fitts returns from the IL, the Boston Red Sox now find themselves with a bit of a rotation logjam — and a former cornerstone could find himself the odd man out if he doesn't pick up his play.
