Preview
The Cleveland Guardians visit the Tampa Bay Rays in MLB on Monday, October 19, with first pitch at 8:00 p.m. ET. The regular season is complete, and this is a postseason game. Recent meetings have gone both ways, while Goalorithm’s model gives the Tampa Bay Rays the likelier result.
The model’s probabilities are estimates, not certainties. It gives the Tampa Bay Rays 58.9% to win and the Cleveland Guardians 41.1%. Its likelier result is a Tampa Bay Rays win.
What the model expects
Goalorithm projects 4.5 runs for the Tampa Bay Rays and 4 for the Cleveland Guardians, with 8.5 in all. The model gives the Tampa Bay Rays a 38.7% chance of winning by two runs or more, compared with 26.2% for the Cleveland Guardians.
That is a projected game with a narrow scoring gap, even as the model leans toward the Tampa Bay Rays to win. The margin probabilities offer a separate view: the model’s chances of a win by two runs or more are lower for either club than its overall win probability.
