How to Use Underdog Promo Code LABSNEWS for MLB Lineups
Right now, you can use the Underdog promo code LABSNEWS to submit a $5 MLB lineup. Win or lose, you get $50 in fantasy bonus entries, making it one of the best MLB DFS promos today.
On Sunday, May 31, you can submit an MLB DFS lineup with picks from Sunday Night Baseball. Tune into Cubs vs. Cardinals at 7:20 p.m. ET on NBC. Check out my favorite MLB DFS picks for tonight’s game.
Pete Crow-Armstrong Higher Than 0.5 Hits: Crow-Armstrong enters tonight’s matchup with massive momentum after exploding for a 4-hit performance, including a home run, against St. Louis yesterday. Facing left-hander Matthew Liberatore, the red-hot outfielder is in a prime position to carry that rhythm forward and cash this line with a single knock.
Masyn Winn Lower Than 1.5 Hits + Runs + RBIs: Winn has cooled off significantly at the plate, carrying a quiet .234 batting average into Sunday’s contest after a hitless 0-for-2 performance yesterday. Going up against Jordan Wicks and a tough Cubs pitching staff makes it highly probable he stays under this multi-stat threshold tonight.

If your Underdog lineup includes three or more picks, you choose between Standard and Flex entries. The Standard format offers a higher payout but requires every pick to hit, while the Flex entry lowers payout upside but allows you to still cash in if one pick misses.
Don’t miss this offer from one of the top DFS sites. Use the Underdog promo code LABSNEWS and claim your $50 bonus for today’s games. Be sure to check confirmed MLB lineups before locking in your entry.
