MLB playoff odds: the race is narrowing fast

MLB playoff odds are at the point where one game can flip the shape of a team’s September. Cleveland (70-70, 30–40%Exact) and Detroit (64-75, 30–40%Exact) are both on the board in the night’s most consequential matchup, and the margin is thin enough that the loser takes a real step back from the field.

Toronto Blue Jays at Kansas City Royals carries almost the same weight: 13.7 points of expected impact, with Toronto favored at 50–60%Exact. A Blue Jays win lifts playoff odds from 30–40%Exact to 40–50%Exact; a loss leaves the door noticeably tighter at 30–40%Exact versus 40–50%Exact for the swing.

Texas Rangers vs Tampa Bay Rays is the other clean leverage game. Texas (70-71, 30–40%Exact) is the underdog at 40–50%Exact, and the swing runs from 20–30%Exact with a loss to 40–50%Exact with a win.

Arizona Diamondbacks at Houston Astros is a smaller but still meaningful postseason hinge. Arizona (74-67, 40–50%Exact) is at 40–50%Exact win probability, and the playoff picture shifts from 40–50%Exact to 50–60%Exact depending on the result.

San Diego Padres vs New York Yankees rounds out the top group. San Diego (73-67, 40–50%Exact) is at 40–50%Exact to win, with playoff odds moving from 30–40%Exact to 50–60%Exact on the result.
