Pitcher
Dallas Keuchel, HOU at KC ($52): The Royals have tallied the second lowest wOBA in the league against lefties, while notching a bottom five RAA against the fastball. Keuchel has registered a 12.0 RAA with the pitch, and he carries an ERA of 1.67 in 11 starts this season.
Mike Foltynewicz, ATL vs. PHI ($34): It can be argued that Zack Greinke is the next best play, but Foltynewicz represents an intriguing option for those who do not wish to get too heavy with the chalk. The Phillies hit the ball on the ground at a 47 percent clip, which should allow the 25-year-old to get his share of stress-free outs. Philadelphia will also come into the contest sporting a bottom 10 ISO against right-handed pitchers.

Catcher
Manny Pina, MIL vs. SF ($8): It should come as little surprise that Ty Blach struggles away from the cavern that is AT&T Park (5.64 ERA), as he has struck out just 10 percent of the batters he has faced this season. Pina has notched a .340 wOBA against his opposite hand while securing a 47 percent hard contact rate over 39 at-bats.
First Base
Matt Carpenter, STL at CIN ($17): Players need to consider stacking against Bronson Arroyo for as long as the Reds keep throwing him out there. He throws a fastball that has tallied a -16.4 RAA, which may help explain his 6.24 ERA over 11 starts. Carpenter may be cooling down a bit after a nice start to the season, but still carries a 3.7 RAA against the fastball along with a .203 ISO against righty pitching.
Second Base
Javier Baez, CHC vs. MIA ($13): Right-handed hitters have gotten the better of Jose Urena since his first pitch of 2017, as he has allowed a .618 slugging percentage against same-handed bats over 25.1 innings. Baez shouldn't have to worry about punching out against Urena, and will bring a .221 ISO against righties to the matchup.
Third Base
Miguel Sano, MIN at SEA ($22): It's hard to imagine a better matchup for Sano, as opposition starter Yovani Gallardo likes to keep the ball on the ground, and has tallied a -4.2 RAA with his fastball. Sano has logged a 15.4 RAA against the fastball, while hitting the ball in the air at a 46 percent clip.
Shortstop
Elvis Andrus, TEX vs. NYM ($21): Zack Wheeler's strikeout numbers take a sizeable dip against same-handed batters, as his 17 percent punchout rate represents an 11-point drop from his numbers against lefties. Andrus has swung the bat well against righty hurlers, having logged a .160 ISO and .356 wOBA against them over 181 at-bats in 2017.
Outfield
Ender Inciarte, ATL vs. PHI ($17): Jerad Eickhoff's below average fastball (-5.0 RAA) has contributed to a 5.13 ERA this season. Meanwhile, Inciarte has notched a 4.2 RAA against the pitch, and has collected a .398 wOBA at hitter-friendly SunTrust Park over 101 at-bats.
Brett Gardner, NYY vs. BOS ($21): Rick Porcello has actually upped his swinging strike rate nearly three percentage points, but three below average pitches have resulted in a 4.24 ERA for the right-hander over 12 starts. Gardner has tallied an improbable 10.1 RAA against the fastball, while sporting a .253 ISO against his opposite hand.
Mookie Betts, BOS at NYY ($22): CC Sabathia has thrown the ball well this season, but he may be dancing through some raindrops, as he has allowed a 39 percent hard contact rate against right-handed hitters. Betts has shown his power stroke against southpaws, notching a .243 ISO and a 34 percent hard contact rate over 37 at-bats.
