The high-end pitching options are slim Saturday night, but some still provide value with a surprising Colorado arm leading the way. On the other end, there are a few pitchers you can stack against, with Yefry Ramirez moving back into a starting role for Baltimore.
PITCHER
German Marquez, COL at SF ($51): Marquez costs the most, yet there are no other reasons not to use him. He's hit 11 strikeouts in his last three starts and has managed at least 29 fantasy points in each of those performances. It matches well with the Giants, who have been the worst team against righty arms since the beginning of August with a brutal 25.3 K%, .112 ISO and .260 wOBA.
Reynaldo Lopez, CWS at BAL ($34): Lopez has gone under the radar mainly because he wasn't good during the first half of the season and also plays for the White Sox. That hasn't stopped him from allowing just 15 hits and four runs over his last four starts. He's hit 20 fantasy points in each of those and most recently went six scoreless and struck out 10 against the Angels. The Orioles should help even more with a 22.7 K%, .118 ISO and .283 wOBA against righties in the last month.

CATCHER
Omar Narvaez, CWS at BAL ($11): Narvaez doesn't break the bank and his numbers against righty hurlers are respectable with a .351 wOBA standing out. The Orioles are turning to Yefry Ramirez once again, who last made a start on Aug. 19 and allowed seven runs. In fact, he never made it more than five innings in any of his starts, allowing at least three runs in six of those.
FIRST BASE
Josh Bell, PIT at MIL ($16): Bell's on a nice run with three doubles and two home runs in the last week – and that's only adding to his .335 wOBA against righty arms. Zach Davies is unpredictable on the mound with a .374 OBP allowed to lefty bats this year after allowing a .335 wOBA last season.
SECOND BASE
Jose Altuve, HOU vs. ARI ($15): Altuve's always worth using when he comes at a discount with a .376 wOBA against righties shining through after it was at .403 last year. Zack Godley has fallen apart in the last month, giving up at least four runs in four of his last five starts.
THIRD BASE
Yolmer Sanchez, CWS at BAL ($15): The White Sox could go off on Ramirez so I'm planning on using a few of their bats. Sanchez sports a .382 OBP over his last 100 plate appearances against righties, which is enhanced by 42 extra-base hits – including 27 doubles. Ramirez doesn't possess many good numbers against lefty bats, with a 6.32 xFIP maybe the worst indicator.
SHORTSTOP
JT Riddle, MIA at PHI ($12): There aren't many desirable places to go for Miami, but Riddle's at least been productive with a .391 OBP against righties in his last 64 plate appearances to go with a .171 ISO for this season. That puts him in the conversation against Vince Velasquez, who has struggled with a 1.64 HR/9 and .359 wOBA allowed to lefties this year. If Riddle doesn't start because of a sore wrist, Andrelton Simmons is worth a look in the same range.
OUTFIELD
Mitch Haniger, SEA at LAA ($20): Haniger's been Seattle's most productive bat against southpaws with a .385 OBP in his last 52 plate appearances and .353 wOBA for the season. Andrew Heaney has been fine against the Mariners in three starts this year, allowing 11 runs and five home runs in 18 innings. To help, all 21 of Heaney's homers allowed have come against righties, as seen in a 1.48 HR/9.
Marwin Gonzalez, HOU vs. ARI ($15): Gonzalez still comes at a discount after missing a few games last week. His overall numbers aren't amazing, but he's been one of Houston's better bats against righty arms with a .364 OBP and .206 ISO since the break. Godley is struggling a bit and owns an inferior .325 wOBA allowed to lefty hitters.
Adam Engel, CWS at BAL ($12): If you need to save cash, Engel is worth a look against an iffy pitcher. He also comes in with a nice .358 BABIP over his last 80 plate appearances against righties, including all six of his homers. That's not a ton of power, though Ramirez is giving up 1.69 HR/9 to righty bats.
