Milwaukee is one win from the first championship in franchise history. The Brewers lead the World Series 3-0 after winning Game 1 3-2, Game 2 5-4 and Game 3 10-1. Game 4 starts at 8 p.m. ET Tuesday, October 27, 2026, at Tropicana Field in St. Petersburg.
Tampa Bay has never won a title. The Rays lost to the Phillies in five games in 2008 and to the Dodgers in six games in 2020. They now face elimination behind Griffin Jax. Milwaukee has not announced a starter, and manager Pat Murphy is expected to use a bullpen game.
Our pick is Under 7.5.
The number
- Model total: 7.5 - Market total, per our engine: 8.5 - Gap: 1.0 run toward the Under - Model confidence: 52.2 - Projected score: Milwaukee 5, Tampa Bay 2, which is 7 combined runs
The pick summary lists model probability and market-implied probability as n/a, edge as None, and model confidence as None. The verified game data, however, reports confidence at 52.2. We are publishing both values as they appear rather than choosing one. We are not presenting a percentage edge because the engine did not produce one. The only quantified signal here is the one-run gap between our total and the market total.
Quoted totals for this game vary. One listing in our research shows the total at 7, with Milwaukee at -142 as road favorites. We cannot reconcile that figure with the 8.5 in our engine, so we set it aside.
This pick is graded at 7.5. The number matters a great deal. At 7.5, a 7-run game clears the Under. At 7, the same game is a push.
Why the model leans this way
Projection versus line. The model's projected 5-2 score totals 7 runs, half a run under the pick line and 1.5 runs under the market's 8.5. Of the three games in this Series, the two closest went 5 runs (3-2) and 9 runs (5-4). The 11-run Game 3 is the outlier.
Neutral environment. The park factor is 1.0, so the model adds no run-scoring boost or penalty for Tropicana Field. The total rests on the two teams themselves.
Evenly matched offenses. Tampa Bay's offense rating is 40.2 and Milwaukee's is 40.0. Neither lineup grades as a significant edge over the other, and the model does not project either one to run away from opposing pitching.
Milwaukee's pitching depth. The Brewers' expected bullpen game draws on a fully rested group:
- Possible early-innings options: Shane Drohan, Dustin May and Kyle Harrison - Available late: Abner Uribe, Aaron Ashby and Trevor Megill
Brandon Woodruff, once lined up for a Game 4 role, pitched the ninth inning of Game 3 instead. Even so, Murphy can match up inning by inning, and every reliever enters fresh.
Jax's regular season. Griffin Jax went 8-10 with a 3.53 ERA. That is a run-suppressing baseline for a pitcher starting at home with the season on the line.
Tampa Bay's bullpen. Closer Bryan Baker has not pitched in the Series. If the Rays hold a lead or stay close late, he is available.
Form. Milwaukee has won 5 straight, and Tampa Bay has lost 1 straight in the model's form inputs. The model reads that as Brewers control of the game, not as a high-scoring game.
The case against
This is a thin position, and the reasons it loses are concrete.
Jax's postseason has been worse than his regular season. He has a 6.00 ERA across two playoff appearances, including three runs over four innings in ALCS Game 3 at Cleveland. If he gives up three runs early again, the Under is under pressure before Milwaukee's bullpen faces many hitters.
Milwaukee's lineup is producing. The Brewers scored 10 runs in Game 3. William Contreras had three hits Monday and is 7-for-13 with three RBIs in the Series.
Bullpen games add variance. Using several pitchers means more matchups and more chances that one reliever has a bad night. A single crooked inning from any of the arms named above could decide the total.
Elimination games create late-inning pressure. Facing a sweep, Tampa Bay may push its pitching usage hard and play for big innings. A game that is tied or close late can stretch into extra innings, and extra innings tend to add runs.
Ordinary baseball variance. A model total of 7.5 sits exactly on the line. The model's projection reaches the Under by only half a run. With confidence reported at 52.2, this is close to a coin flip. We expect this pick to lose a large share of the time, and a loss here would be consistent with a sound process.
Line availability. If the only total available is 7, the projected 7-run outcome becomes a push rather than a win. Grading at 7.5 reflects our published number, not a guarantee that number is widely available.
