Pitcher
Mike Foltynewicz, ATL vs. MIL ($6,300): Foltynewicz has never reached the level of "good pitcher," but he's maintained a solid 18.8 percent K-rate and has encouragingly brought his BB-rate down to just 2.2 percent so far this season. The number of home runs he allows is a major issue but at such a low tag and facing the most strikeout-prone team in the league, he warrants consideration. It also helps to swallow the pill on such a cheap, risky play when the highest-priced pitcher on the slate is a knuckleballer in a 9.5 over/under game.
Catcher
Evan Gattis, HOU vs. BAL ($3,000): While Gattis's seasonal number still lag, narrowing down to just the last week he has a .435 wOBA and 183 wRC+. His continued eligibility at catcher boosts his value via opportunity cost. Opposing pitcher Tyler Wilson has been fairly equally mediocre against both righties and lefties throughout his brief career.
First Base
Steve Pearce, TB vs. MIA ($3,600): When a lefty is on the mound, especially one that struggles mightily against righty batters as Justin Nicolino (6.02 xFIP against them on the season), all hands aboard the Rays' stack. The lineup will read righty from top to bottom, many of which are specialists in the southpaw-rocking department. Pearce owns a .447 ISO, .566 wOBA and 279 wRC+ against lefties this season. Safe to say he's a lefty-killer specialist.
Second Base
Phil Gosselin, ARI at PIT ($2,000): Gosselin has a solid .338 wOBA and 115 wRC+ against lefties in his career. He may find himself slotted in the two-hole against lefty Jeff Locke, an undeniable bargain for the minimum price if he does get the nod.
Third Base
Evan Longoria, TB vs. MIA ($4,000): Longoria's career numbers against lefties include a .247 ISO, .384 wOBA and 146 wRC+. Longoria's career has seemingly past its peak, but the high potency of both himself and the Rays lineup against lefties is explosive. The Miami bullpen may end up being the number one limiting factor for the Rays on Wednesday.
Shortstop
Manny Machado, BAL at HOU ($3,700): It feels almost as if I'm copying and pasting every week, but shortstop eligibility and an unquestionably low price has kept Machado's spot as an excellent play on nearly every slate. Collin McHugh is a mediocre pitcher with a 5.13 ERA this season, while Machado ranks near the top of every hitting category with a .313 ISO, .414 wOBA and 166 wRC+ on the season.
Outfield
Mikie Mahtook, TB vs. MIA ($2,000): Mahtook is finding his way back into the lineup against lefties. Now listed at min price, a likely spot in the two-hole and career numbers of .347 ISO, .423 wOBA and 173 wRC+ against southpaws makes him an optimal play. It's worth noting though that once the bullpen was called upon last time Mahtook got the start against a lefty, he was removed for a pinch hitter.
Brandon Guyer, TB vs. MIA ($3,400): Take those Rays bats against the mediocre southpaw, Justin Nicolino. I'm sounding repetitive, but it's for good reason. This season, Guyer owns a .470 wOBA and 212 wRC+ against lefties. He also owns the number one spot in the order. He's the last of four Rays bats I'll mention in the article, but he's far from the last bat you should consider.
Joc Pederson, LAD vs. CIN ($3,100): Dan Straily's career xFIP against lefties: 5.23. Joc Pederson's wOBA against righties this season: .398. After an abysmal end to last season and despite his inability to hit fellow lefties, Pederson has somewhat quietly returned to his righty-hitting ways.
