Top MLB picks for Friday, July 31

After simulating every Friday MLB game 10,000 times, the model is backing the Cardinals +1.5 (-149) to cover the run line against the Blue Jays. St. Louis has been the better team from a season-long perspective, but the Blue Jays are favored in this game largely because Dylan Cease (7-5, 2.46 ERA) is on the hill. St. Louis, however, counters with Kyle Leahy, who has been strong as well with a 3.55 ERA. 

The model is projecting this game to be almost 50/50 with the Blue Jays winning 53% of the time. With such a small margin, the Cardinals covering +1.5 runs hits 70% of the time, making it an A-rated value, according to the model. See which other MLB parlay picks to make here.
