The 2022 MLB season continues on Saturday, and one of the marquee games on the schedule will be Red Sox vs. Cardinals at 7:15 p.m. ET as both teams are in the thick of the MLB playoff hunt. St. Louis is currently first in the NL Central while Boston is fourth in the AL East, but with a 35-30 record the Red Sox are only a half-game out of the final AL Wild Card spot. The Red Sox survived a four-run ninth inning from the Cardinals to win Game 1 of the series 6-5 on Friday night and will send Kutter Crawford to the mound to take on Dakota Hudson on Saturday.

Boston is the -120 (risk $120 to win $100) home favorite in the latest MLB odds from Caesars Sportsbook and the over-under for total runs is at 10. It's one of two games on the Saturday MLB schedule with a total listed in double-digits, and it will be interesting to see if these two offenses can stay hot against a couple of back-of-the-rotation pitchers.

One of the MLB picks the model likes for Saturday: San Diego (-120) beats Colorado (see tickets at StubHub). These division rivals split a four-game series last weekend and the Rockies won Game 1 of the series 10-4, which has helped created some value on the side of the NL West leaders. San Diego has a half-game lead over the Dodgers in the division and is 11-6 with a 45-run differential in the month of June.

The Padres have a 3.43 team ERA on the season that ranks second in the National League and Nick Martinez is scheduled to take the bump on Saturday. After four seasons in Japan, the 31-year-old has been a pleasant surprise for the Padres with a 3.74 ERA and 56 strikeouts over 55 2/3 innings. The model expects Martinez to continue pitching well and has San Diego winning in nearly 60 percent of simulations.
