Eickhoff is working on improving his changeup this spring, Todd Zolecki of MLB.com reports.

EDGE Analysis

Eickhoff used his changeup just 5.2 percent of the time last season. If he can make strides with the pitch this spring it could help him improve on the .274 average and .822 OPS that left handed batters had against him last season. Eickhoff, who allowed one run over two innings in his spring debut Monday, is expected to start the second game of the regular season for the Phillies.
