EDGE Analysis

Phelps had been rehabbing at High-A in an effort to make it all the way back from Tommy John surgery, and it appears he's closing in on a return to the big leagues. The Blue Jays figure to continue to exercise caution with the right-hander, so he may need a handful of appearances with the Bisons before coming off the injured list.
