Who Stands Out with Underdog Tonight?

Underdog has one of the widest player lineup boards out there right now. With two NLCS series set for tonight, we have done a deep dive on who is performing in their series right now, and who we’re watching coming into Tuesday.

Dodgers vs. Braves (series tied 1-1)

• Max Muncy (LAD): Muncy homered in both games, including a two-out solo shot in the ninth inning of Game 2.
• Michael Harris II (ATL): Harris collected three hits in Game 2 (a single, a double and a triple) and scored the go-ahead run.
• Teoscar Hernández (LAD): Hernández went 2-for-4 in Game 1 with a two-run homer and two runs scored.
• Ozzie Albies (ATL): Albies crushed a two-run homer in the ninth inning of Game 1.

Brewers vs. Padres (Milwaukee leads 2-0)

• Jackson Chourio (MIL): Chourio hit a two-run homer in Game 1, then won Game 2 with a two-out, two-run single in the ninth.
• William Contreras (MIL): Contreras broke a 2-2 tie with a solo homer in the seventh inning of Game 1.
• Ty France (SD): France drove in runs in the first and seventh innings of Game 2.

For my first entry last postseason, I paired one hitter's total bases with another's runs plus RBI. That simple two-pick approach keeps things easy for beginners. Use your first $5 entry on either game to unlock the Underdog promo code TOPACTION bonus.
