This article is part of our DraftKings MLB series.
Robbie Ray, ARI vs. SF ($12,300): The Giants enter with a second-lowest .292 wOBA against southpaws in the second half, and Ray is an outing removed form a dominant five game stretch with a 1.30 FIP and 44.7 strikeout percentage. He also allowed a single earned run and fanned 10 Giants in one of those five starts. This is a strong setup for Ray to rebound from a disappointing showing against San Diego last time out.
James Paxton, SEA at OAK ($7,600): The hard-throwing lefty has only pitched five innings through two starts since returning from the disabled list, so he checks out as a high-risk, high-reward option. However, his fastball hit 98.4 mph in his latest outing, and he owns a 2.57 FIP and 27.9 strikeout percentage for the season. Additionally, Oakland sports a mediocre .307 wOBA and target-worthy 26.0 strikeout percentage against lefties in September.
CATCHER
J.T. Realmuto, MIA at COL ($4,000): Not only does Realmuto receive the Coors Field boost, he's posted a rock-solid .364 wOBA against southpaws this season. This is a manageable salary, and especially with Tyler Anderson allowing a .372 wOBA to right-handed batters at home this season.
FIRST BASE
Chris Davis, BAL at PIT ($3,100): Even with a disappointing campaign on the books, Davis checks out as a low-priced flier who should be scarcely owned. While Trevor Williams has held lefties to a .322 wOBA, he's been inconsistent and projects as neutral matchup. Davis' salary opens up spending room without sacrificing upside. After all, he still boasts a .270 wOBA against righties over the past four years.
SECOND BASE
Jonathan Schoop, BAL at PIT ($3,900): Another underpriced Oriole, Schoop has posted a .352 wOBA against right-handed hurlers in the second half. As noted, Trevor Williams isn't a slam-dunk matchup (.301 wOBA allowed to righties), but Schoop offers contrarian appeal and cap relief without punting a lineup slot.
THIRD BASE
Alex Bregman, HOU at TEX ($4,200): This is a tough matchup against Cole Hamels, as the veteran lefty has limited right-handed hitters to a .314 wOBA and pitched well in consecutive outings. Still, Hamels owns a 5.00 xFIP against righties, and Bregman enters with an elite .403 wOBA against southpaws.
SHORTSTOP
Corey Seager, LAD vs. SD ($4,000): It's been a disastrous month for the shortstop, as he'd battling an ankle injury and hasn't recorded an extra-base hit since Sept. 15. This is a potential buy-low spot, though. The Dodgers have won four of five, and Seager still boasts a career .380 wOBA against righties. Dinelson Lamet has surrendered a .500 slugging percentage and .363 wOBA to left-handed hitters, too.
OUTFIELD
Giancarlo Stanton, MIA at COL ($5,700): As noted, Tyler Anderson has struggled at Coors Field this season, and Stanton's salary isn't prohibitive enough to ignore him in the favorable setup. The slugger sports a .440 ISO and .473 wOBA against lefties this season, and Stanton owns a career 1.142 OPS at Coors.
Jay Bruce, CLE vs. MIN ($4,100): This is a reasonable price to target Bruce in a plus-matchup. He's posted a rock-solid .273 ISO and .365 wOBA against right-handed pitchers this season, and Bartolo Colon has allowed a .387 wOBA to lefties. Hitting in the heart of the scorching Cleveland lineup is a nice bonus for Bruce, too.
Kole Calhoun, LAA at CWS ($3,400): The RotoWire lineup optimizer highlighted Calhoun's value at this salary. While the outfielder isn't having his best season, he's been better in the second half with a respectable .338 wOBA against righties and lands in a ripe matchup. Chris Volstad hasn't made a start in the majors since 2012, and he allowed a .346 batting average to left-handed hitters this season with Triple-A Charlotte.
