Yankees vs Red Sox Underdog promo code details

The Underdog promo code COVERS delivers $50 in fantasy bonus entries after placing an initial $5 entry. This welcome bonus applies perfectly to Wednesday's Yankees-Red Sox game, where left-handers Ranger Suarez and Max Fried are set to duel at Fenway Park. New users can create fantasy lineups featuring players like Giancarlo Stanton, who homered and doubled in Tuesday's victory, or Cody Bellinger, who extended his hitting streak to nine games.

The bonus entries arrive within 72 hours and carry a 1x wagering requirement that must be completed within 14 days. Users have 60 days to utilize their bonus before expiration. For example, if you place a $5 entry on a Yankees-Red Sox player prop and win, your winnings are immediately withdrawable after account verification. If your initial entry loses, you still receive the full $50 bonus to continue playing. This offer excludes residents of New Jersey, New York, Maryland, Ohio, Michigan and Pennsylvania.
