Washington hasn't officially announced its starting pitcher for Tuesday, but it will be a bullpen-type start with Joe Ross or Reynaldo Lopez toeing the rubber first.
PITCHER
John Lackey, CHC vs. SF ($43): The veteran owns a career 3.11 ERA in the postseason, with 20 starts and three relief appearances on his resume. He also finished 2016 strong with 24 strikeouts and a 3.00 ERA over 30 innings through his final five outings. San Francisco also posted a middle-of-the-pack .318 wOBA against righties this season.
Julio Urias, LAD vs. WAS ($31): In addition to the unknown of Washington's starter, Chicago has dominated lefties (.347 wOBA this season), which limits Matt Moore's appeal. Urias has a difficult matchup in his own right, as the Nats returned a solid .332 wOBA against southpaws this season. Still, Urias has strikeout upside (25 percent K-rate) and has allowed just five earned runs over his past 33.2 innings for a 1.34 ERA with 33 punch outs.

CATCHER
Buster Posey, SF vs. CHC ($16): Hitting in the heart of the Giants' order, Posey is 5-for-13 in this series with a .429 OBP. He slowed significantly over the second half of the season (.324 wOBA), but checks out as the top option from the shallow pool of catchers. Plus, he boasts a .351 wOBA against right-handed pitchers over the past three seasons.
FIRST BASE
Adrian Gonzalez, LAD vs. WAS ($15): While 2-for-13 during the series, Gonzalez posted a .362 wOBA against right-handed pitchers this season. He also hits in the heart of the order and has five postseason home runs during his career.
SECOND BASE
Ben Zobrist, CHC at SF ($15): The veteran has a .367 wOBA against southpaws this season and continues to hit in the middle of a potent lineup. His 160 postseason plate appearances should be viewed as a positive, too.
THIRD BASE
Kris Bryant, CHC at SF ($18): Look for Bryant to parlay his ninth-inning heroics and monster fantasy showing Monday into another big return on investment against Matt Moore. Bryant posted a whopping .438 wOBA against lefties this season, after all.
SHORTSTOP
Corey Seager, LAD vs. WAS ($19): Since entering the league, Seager owns a .405 wOBA against right-handed pitchers, and he already has two home runs during the series. He's worth spending up for.
OUTFIELD
Dexter Fowler, CHC at SF ($18): A key offensive catalyst for the Cubs, Fowler's .396 OBP and .380 wOBA against lefties this season are target-worthy marks. With a 2-for-12 start to the series and a high salary, Fowler's ownership could be low, too.
Joc Pederson, LAD vs. WAS ($17): The sophomore has teed off on right-handed pitchers this season with a .278 ISO and a .386 wOBA. There is a chance his ownership is low because of his hefty price, too.
Jorge Soler, CHC at SF ($8): While definitely a sit risk, Soler has another opportunity to cash in against a left-handed arm Tuesday. He returned a .200 ISO and .351 wOBA against lefties this season and showed well last season with three playoff bombs.
