Hunter Renfroe hasn't been posting jaw-dropping numbers this season, with a .326 wOBA and solid .197 isolated slugging (ISO), but it's what he does against left-handed pitching that really stands out.

He has a .357 wOBA and .233 ISO in 51 plate appearances against southpaws this year, and if we extend our view to all three of his Major League seasons (giving us a much more significant 191-plate-appearance sample), he has turned a 40.5% hard-hit rate and 51.1% fly-ball rate into an outstanding .418 wOBA and .337 ISO.

Texas Rangers lefty Cole Hamels is having a decent season so far, but he's giving up some huge contact to right-handed bats. The 47.6% hard-hit rate, 14.8% soft-hit rate and 37.8% fly-ball rate that he is allowing in the split make this a terrific spot for Renfroe to continue his excellent work against southpaws.
