FanDuel Price: $3,100

As the Philadelphia Phillies try to claw their way to the top of the National League East, they've received a major shot in the arm from starter Zach Eflin. The 24-year-old righty has been solid this year, and he's performed well largely due to holding same-sided bats to a 28.4% hard-hit rate and .261 wOBA.

Amed Rosario has risen to the leadoff spot in 9 of the last 10 games for the New York Mets, and that's made him an attractive DFS asset. Unfortunately, against righties this season (308 plate appearances), Rosario has logged a .273 wOBA and 28.3% hard-hit rate.

Despite seven hits, including a home run, and three steals in his last six contests, Rosario is tough to get behind versus a righty-killer like Eflin.
