Red Sox vs. Cardinals: Over 8 runs (-108)

Expectations weren't high for the Cardinals entering this season, but their offense has performed well lately. St. Louis has scored at least five runs in five of its last six games, however, pitching has failed them at times, allowing at least six runs in three of those contests. This is the ideal recipe for an Over bet, though. The Over went 3-2-1 over those six games, with at least eight runs scored in four of those six games. The Cardinals are scheduled to start Kyle Leahy, who has a 5.40 ERA in two starts. The Red Sox are scheduled to start Ranger Suarez, who has an 8.64 ERA in two starts this season. The model projects the Over to hit in 65.6% of simulations. Back the Over at DraftKings here, and claim $300 in bonus bets if your first $5 bet wins as a new user:

Golden Knights vs. Avalanche: Over 6.5 goals (+114)

Colorado is the top-scoring team in the NHL at 290 goals (3.7 goals per game), while the Golden Knights have an above-average offense of their own, ranking 14th at 3.18 goals per game. The Knights and Avalanche played to a shootout after a 5-5 regulation when they last met on Dec. 27. Four of the last seven Las Vegas games went Over this total, with two of the three that didn't being six-goal contests. The model projects the Over to hit in 67.8% of simulations.

Carlos Ulberg to defeat Jiri Prochazka by KO/TKO/DQ (+175)

"This is a fun fight that I don't expect to go the distance," SportsLine expert Kyle Marley said. "Both guys are dangerous and throw solid volume. Either can mix in takedowns, but I expect a striking match. Jiri is more wild and unpredictable. Ulberg is more technical and defensively sound. I think Ulberg should be the slight favorite here, so I'll take him by knockout." Back Ulberg to win at DraftKings here, and claim $300 in bonus bets if your first $5 bet wins as a new user:
