Polymarket MLB Thursday Probabilities

Here is a look at today’s implied (vig-free) probabilities to help you find the best value on the board.

MatchupProbability
TOR @ TBTOR 34% / TB 66%
ARI @ BOSARI 40% / BOS 61%
SEA @ MILSEA 46% / MIL 55%

When handicapping these probabilities, the stats show exactly why Tampa Bay is favored so heavily. The Rays carry a major advantage on both sides of the ball, boasting a 3.83 team ERA and a .740 OPS, while the Blue Jays lag behind with a 3.96 ERA and a sluggish .682 OPS.

I am also looking closely at the Milwaukee Brewers at home against Seattle. The Brewers just handed the Mariners an absolutely historic 22-0 shutout yesterday. To make matters worse, Seattle’s Julio Rodrรญguez literally threw the ball into the stands thinking there were three outs during the game. With an elite 3.43 team ERA compared to Seattle’s 3.97, and a much more productive lineup (.733 OPS vs. .686), Milwaukee looks like a prime spot to lock in a wager.
