PITCHER
Dan Straily, CIN at LAA ($37): With a 1.98 ERA, six wins and 43 punchouts through 50 innings in his last eight starts, Straily has been one of the best arms since the All-Star break. He has allowed two runs or fewer in each outing and faces the Angels, who have averaged just three runs per game over their last nine outings and the second fewest runs this month.
Matt Boyd, DET vs. CWS ($32): Boyd is settling in as a reliable hurler, winning five of his last eight with a 2.38 ERA over his last nine (one in relief). He's even struck out 43 batters over 45.1 innings during the span, which makes him a potential low-priced flier Monday. Chicago is a middle-of-the-pack team against lefties (.325 wOBA and 101 wRC+), and the White Sox have scored the eighth-fewest runs in the league in August.

CATCHER
Wilson Ramos, WAS at PHI ($13): Despite being a right-handed hitter, Ramos has posted a .359 wOBA and 123 wRC+ against right-handed pitchers this season. He has a great matchup against Jake Thompson on Monday, too. The rookie righty has allowed 21 runs over 19.1 innings through his first four career starts.
FIRST BASE
Eric Hosmer, KC vs. NYY ($13): Hosmer has six runs, two homers, 11 RBI and a .543 slugging percentage through his previous 11 games and a .365 wOBA and 129 wRC+ against righties the last two seasons. He presents great value in a matchup against Michael Pineda, who has served up a .469 slugging percentage and .344 wOBA to left-handed batters this season).
SECOND BASE
Jose Altuve, HOU vs. OAK ($22): The salary isn't prohibitive enough to fade Altuve with a lefty on the hill. He's posted a .440 wOBA and 184 wRC+ against southpaws this season, and Sean Manaea has allowed a .493 slugging percentage and a .350 wOBA to right-handed hitters.
THIRD BASE
Matt Carpenter, STL at MIL ($14): At this cap hit, Carpenter is a steal. He has a .403 wOBA and 154 wRC+ against right-handed hurlers for the season, and Zach Davies has surrendered a .334 wOBA to left-handed batters this year.
SHORTSTOP
Troy Tulowitzki, TOR at BAL ($17): The last two seasons, Tulowitzki has returned a .370 wOBA and 127 wRC+ against left-handed pitchers, and he makes an affordable stack option in the Blue Jays lineup. Additionally, Wade Miley has struggled against right-handed bats this season, allowing a .509 slugging percentage and .367 wOBA.
OUTFIELD
George Springer, HOU vs. OAK ($20): The third-year outfielder has eaten up southpaws this season for a .300 ISO, a .425 wOBA and 173 wRC+. He's a lineup building block at a reasonable salary against Sean Manaea, who has allowed a .350 wOBA to right-handed batters this season.
Christian Yelich, MIA at NYM ($18): It's been a solid campaign against righties for Yelich, as he's posted a .397 wOBA and 149 wRC+ with a .933 OPS. He also lands in a nice matchup Monday. Rafael Montero has rewarded left-handed batters with a .585 slugging percentage and a .423 wOBA the last three seasons.
Jose Bautista, TOR at BAL ($14): This is a nice price point to target Bautista. He has a .391 wOBA and 151 wRC+ the last three seasons against southpaws, and Wade Miley has served up a .340 wOBA to right-handed batters during the same timeframe.
