PITCHER
Carlos Martinez, STL vs. MIL ($45): Martinez's ground ball tendencies should work to his advantage against the Brewers, who are a bottom-10 team when it comes to fly ball percentage. The 24-year-old should also have a significant edge in his home ballpark, as the Brewers have just a .307 wOBA in games played on the road. Martinez has been on a nice run of late, allowing five runs and striking out 31 batters over his last four starts (27 innings).
Robert Gsellman, NYM at ATL ($31): Gsellman is unlikely to hold onto his 2.87 ERA unless he improves his strikeout and walk numbers, but his 48 percent ground ball rate should give him a leg up against the Braves, who hit the third fewest fly balls in the league by percentage. It is also worth noting that the Braves have the third-lowest ISO against right-handed pitchers.

CATCHER
Wilson Ramos, WAS vs. PHI ($11): Ramos has been significantly better against lefties this season, but he still carries a .351 wOBA and a 35 percent hard contact rate against righties. We should be looking to stack as many cheap options against Jake Thompson as possible, as he has a 6.48 ERA and a 1.9 HR/9 rate over 33.1 innings (six starts).
FIRST BASE
Mike Napoli, CLE at MIN ($13):Tyler Duffey pitched well at Triple-A Rochester this season, but he has been hit hard by major leaguers, as he has been saddled with a 6.24 ERA over 115.1 innings. Napoli sports an impressive 7.0 runs above average mark against the curveball, a pitch Duffey throws 38 percent of the time.
SECOND BASE
Ryan Schimpf, SD vs. COL ($14): Schimpf is a fly ball machine, putting the ball in the air more than 63 percent of the time. Opposing starter Tyler Chatwood leans heavily on his fastball to get grounders, which should allow Schimpf to feed his .367 ISO.
THIRD BASE
Todd Frazier, CWS vs. KC ($13): The beat goes on for Frazier, who has 35 homers despite posting just a .214 batting average. Yordano Ventura is able to get a ground ball 51 percent of the time, which should play into Frazier's 49 percent fly ball rate.
SHORTSTOP
Asdrubal Cabrera, NYM at ATL ($19): Cabrera has shown solid power against righties this year, notching a .199 ISO over 331 at-bats. Julio Teheran is the best pitcher in Atlanta's rotation, but he has allowed 1.4 HR/9 rate and a 5.48 xFIP against his opposite hand.
OUTFIELD
Jackie Bradley Jr., BOS at TOR ($13): While opposing starter Marco Estrada has been successful this season, he may not have the ideal profile for the Rogers Centre, as a 47 percent fly ball rate has led to a 1.3 HR/9 rate. Bradley has performed well against righties this season, logging a .268 ISO and a .383 wOBA over 126 games.
Carlos Beltran, TEX at LAA ($17):Tyler Skaggs has pitched well in his last two outings, but he still carries a 1.4 HR/9 rate over 31.2 innings against righties. Beltran has impressed against lefties on the road this year, amassing a .365/.390/.608 slash line with four home runs in 74 at-bats.
Corey Dickerson, TB at NYY ($15):Michael Pineda needs to find a way to keep the ball in the yard at Yankee Stadium, where he has allowed 16 homers in just 74.2 innings. Corey Dickerson has shown significant power against right-handed pitchers this season, logging a .249 ISO over 121 games.
Other options: Adam Duvall, CIN at PIT ($17); Gregory Polanco, PIT vs. CIN ($13); Angel Pagan, SF at ARI ($12)
