PITCHER
Tanner Roark, WAS at ATL ($42): I was actually a bit disappointed when I saw that Roark and his 2.81 ERA was facing the Braves, as we likely won't get anywhere near the scarcity we would get with a struggling or unknown pitcher. We still need to roll with Roark for the matchup, as the Braves have the second-lowest wOBA in the league against right-handed pitchers, and they should struggle against a hurler with such a heavy ground ball profile.
Adam Wainwright, STL at PHI ($32): The reduced price comes courtesy of Wainwright's dreadful ERA away from Busch Stadium, which currently stands at 6.72. He is worth a look against the Phillies, however, as they have the third-lowest wOBA in the league against righty hurlers. It is also worth noting that they are a bottom-10 team against the curveball and cutter, according to runs above average, and those two offerings make up nearly 60 percent of Wainwright's pitch usage this season.

CATCHER
Evan Gattis, HOU at BAL ($15): Gattis packs a serious punch against left-handed pitchers, as evidenced by his .290 ISO over 124 at-bats. Meanwhile, Wade Miley has had trouble keeping the ball in the park against righties, surrendering 17 homers in 97.1 innings.
FIRST BASE
Mike Napoli, CLE vs. TOR ($24):Francisco Liriano should have his hands full with Napoli, as he has the third-highest runs above average score against the slider, a pitch the southpaw throws 31 percent of the time. Napoli has shown a tremendous amount of power against lefties this season, having tallied a .272 ISO in 114 at-bats.
SECOND BASE
Jonathan Schoop, BAL vs. HOU ($9): Schoop has gone through hot and cold streaks this year, and while he seems to be dealing with the latter at the moment, he still has a .205 ISO against right-handed pitching. Opposing starter Collin McHugh has struggled mightily on the road this season, logging a 5.23 ERA over 63.2 innings.
THIRD BASE
Kris Bryant, CHC at COL ($24):Tyler Anderson has pitched fairly well against both righties and lefties, but the profiles match up so well that I couldn't fade a hitter like Bryant at Coors Field. The first thing to note is Bryant's incredible .310/.416/.628 slash line against left-handed pitching. He also carries an 8.0 runs above average mark against the slider, a pitch Anderson turns to on 27 percent of his offerings. Lastly, Bryant should be able to get some lift off those Anderson offerings, as he hits the ball in the air more than 45 percent of the time.
SHORTSTOP
Didi Gregorius, NYY at LAA ($12): It's never a bad idea to stack hitters against Jered Weaver, as he has tallied a 5.86 xFIP and 1.8 HR/9 rate over 133.2 innings. Gregorius has improved his power numbers against righties of late, and he now has a .190 ISO in 105 games.
OUTFIELD
Stephen Piscotty, STL at PHI ($13): Opposing starter Adam Morgan threw the ball reasonably well while on his rehab assignment, but he has been torched by righties at the major league level, allowing a .614 slugging percentage over 53 innings. Piscotty has had his way with left-handed pitchers this season, compiling a .314/.409/.593 batting line.
Brandon Guyer, CLE vs. TOR ($12):Guyer needs to be considered whenever a lefty is on the mound, as he sports a .602 slugging percentage against his opposite hand over 83 at-bats. Guyer may not have to worry about the strikeout prowess of Liriano, as he goes down on strikes less than 10 percent of the time against lefties.
Bryce Harper, WAS at ATL ($16):Julio Teheran's 2.81 ERA makes him look like an ace, but his peripherals reveal a somewhat startling 5.48 xFIP and 37 percent hard contact rate against left-handed hitters. Harper has continued his fall down the mountain, but his power numbers have remained in tact, as he has a .217 ISO against righty pitchers.
Other options: Coco Crisp, OAK at CWS ($16); Melky Cabrera, CWS vs. OAK ($16); Jackie Bradley Jr., BOS at DET ($13)
