How Underdog Pick'em Works

Underdog Pick'em is a daily fantasy contest format where you build an entry ticket choosing whether selected athletes will finish with More or Less than their listed stat totals. You can combine player stats across different teams or within a single game like Boston vs. New York.

Entries require a minimum of two players (from two different teams) and can include up to eight picks. Underdog offers two distinct payout structures:

1. Standard Play (All-or-Nothing): Every pick on your card must be correct to win. The payout multiplier increases with every pick added (e.g., a 2-pick entry pays 3x your entry fee, 3-pick entries pay 6x, up to higher multipliers on larger cards).

2. Insured Play: You accept a slightly lower maximum payout multiplier in exchange for insurance if one pick fails on a multi-pick entry, you still receive a payout.

Worked Example Walk-Through: Red Sox vs. Yankees

• Pick 1: Aaron Judge (Yankees) - More than 1.5 Total Bases

• Pick 2: Rafael Devers (Red Sox) - More than 0.5 Hits

• Entry Type: Standard Play

• Entry Fee: $10

Outcome Breakdown:

If Aaron Judge records 2+ total bases (e.g., a double or two singles) AND Rafael Devers records at least 1 hit, your 2-pick entry hits. A standard 2-pick Pick'em entry pays 3x the entry amount, turning your $10 entry into a $30 total payout ($20 net profit). If either player fails to reach their stat target, the standard entry settles as a loss.

Red Sox vs. Yankees: Players in the Spotlight

Tonight’s clash in the Bronx features high-profile star power across both dugouts. Here are key performers to keep an eye on when analyzing player statistics:

• Aaron Judge (NYY): The slugger continues to drive the New York lineup, maintaining a heavy slugging percentage against AL East rivals. Judge has recorded multi-base hits in four of his last six starts.

• Juan Soto (NYY): Exhibiting elite plate discipline, Soto has drawn at least one base on balls or recorded an RBI in five consecutive home appearances.

• Rafael Devers (BOS): Boston's premier corner infielder historically thrives in Yankee Stadium, entering tonight's game on a multi-game hit streak and leading the Red Sox in extra-base hits against left-handed pitching.

• Jarren Duran (BOS): Serving as a dynamic spark at the top of the batting order, Duran has logged a combination of runs scored and stolen bases across four of Boston's last five games.

Where Underdog is Available

Underdog Fantasy operates legally across most US states, but specific game formats vary based on local state regulations governing real-money daily fantasy sports.

• Underdog Pick'em Available States (15 States):
  AK, GA, IN, MN, NE, ND, NM, OK, OR, RI, SC, SD, TX, UT, and WI.

• DFS / Draft-Only States (17 States + DC):
  AL, AZ, AR, CA, CO, DE, FL, IL, KS, KY, MO, NC, NH, NY, VA, VT, and WV (+ Washington, D.C.).

Important Distinction: In Pick'em states, users can play both traditional Best Ball/DFS draft contests and More/Less stat projection pick entries. In DFS-only states, statutory guidelines restrict games to standard peer-to-peer draft contests (such as daily snake drafts and season-long Best Ball tournaments).
