This article is part of our DraftKings MLB series.
PITCHER
Johnny Cueto, SF at MIA ($12,400): The price and a tough draw against Jose Fernandez may force some to shy away from Cueto, but the matchup suits his profile so well that I can't resist. The Marlins have the lowest fly ball rate in the league this season, which plays into Cueto's extreme ground ball tendencies. It is also worth noting that Miami has the sixth-lowest runs above average mark against the cutter, a pitch Cueto throws 22 percent of the time.
Michael Wacha, STL vs. CIN ($6,500): Wacha has an xFIP under 4.00 and has not allowed more than three earned runs in a start since July 4. The Reds haven't hit well away from Great American Ballpark this season, notching a wOBA of just .293 on the road.
CATCHER
Cameron Rupp, PHI at LAD ($3,700): Opposing starter Julio Urias bounces from the bullpen to the starting rotation these days, meaning he is unlikely to throw more than three or four innings against the Phillies. Rupp could make things difficult for Urias during his abbreviated stay, as he has a 1.063 OPS and a .346 ISO over 52 at-bats against southpaws.
FIRST BASE
Chris Davis, BAL at OAK ($3,400): Davis has been in a slump for so long his slugging percentage is now below .450, but there are definitely things to like about him in a matchup against Kendall Graveman. The first thing to note is Davis still carries a 46 percent fly ball rate, which should give him an edge against Graveman's extreme ground ball profile. Davis also ranks more than three runs above average against the cutter, a pitch Graveman throws 25 percent of the time.
SECOND BASE
Jorge Polanco, MIN vs. HOU ($3,300): Polanco has hit the ground running since being recalled from Triple-A Rochester late last month, tallying a .315/.377/556 batting line over 20 games. Collin McHugh has had a bit of an issue with the long ball when it comes to left-handers, as evidenced by his 1.3 HR/9 rate in 54.2 frames.
THIRD BASE
Nolan Arenado, COL vs. TEX ($4,700): Arenado has the highest fly ball percentage in the league, which could create an issue for Cole Hamels, whose 49 percent ground ball rate is the second highest mark of his career. Few pitchers are safe from Arenado at Coors Field, where he has a .322 ISO.
SHORTSTOP
Manny Machado, BAL at OAK ($4,100): While not as pronounced as Davis', Machado also has a platoon advantage over Graveman, as he hits the ball in the air more than 43 percent of the time. Machado has shown the majority of his power this season against righties, tallying a .242 ISO over 318 at-bats.
OUTFIELD
Stephen Piscotty, STL vs. CIN ($4,400):Cody Reed needs to be looked at as one of the primary stack options of the main slate, as he has allowed 10 home runs to right-handed hitters over 33 innings. Piscotty has done his best work against his opposite hand this year, resulting in a .441 OBP and .310 ISO in 100 at-bats.
Jose Bautista, TOR vs. TB ($3,500): It seems odd to see Bautista below $4,000, but Joey Bats has struggled since his return from the disabled list, logging just seven hits over 12 games. Still, his .223 ISO is good enough to take against Jake Odorizzi, who holds a 4.77 xFIP against right-handed hitters.
J.D. Martinez, DET vs. SEA ($4,000): Martinez resides on the other end of the spectrum, as he has logged eight hits in 17 at-bats after being sidelined for nearly two months because of an elbow injury. Martinez will bring a .228 ISO against righties into the matchup against Hisashi Iwakuma, whose xFIP against right-handers stands at 4.60.
Other options: Miguel Sano, MIN vs. HOU ($3,900); George Springer, HOU at MIN ($4,200); Joc Pederson, LAD vs. PHI ($4,200); Kirk Nieuwenhuis MIL vs. ATL ($3,800)
