Start: September 14th vs. Miami Marlins
ESPN ownership: 30.4%

Even more so than Rodon, Zach Eflin is hanging onto his owner's good graces by a thread. The Philadelphia Phillies righty sports a cringe-worthy 6.35 ERA across 43.1 frames since the All Star break, a far cry from the terrific 3.15 mark that he amassed in 63.1 first-half frames.

If there was ever a time for Eflin to break out of his slump, it's this week's matchup against the hapless Marlins. Miami has been the worst offense against righties in the second half, with a team-wide OBP of .285 and a group ISO of .110.
