In addition to boosting Milwaukee’s morale toward capturing a maiden title, Monday’s 10-1 dominant win arranged their pitching staff ideally for Game 4. As Tampa Bay was forced to cycle through six different hurlers, the Brewers managed to rest key relief pitchers such as Aaron Ashby, Abner Uribe, and Trevor Megill. This bullpen unit has consistently dominated opposing batters this October, posting a stellar 1.24 ERA across 11 postseason contests, which has propelled the club to a 10-1 playoff record. According to the SportsLine Projection Model, which runs 10,000 simulations for every MLB matchup, Milwaukee holds a 59% chance of emerging victorious.

Tampa Bay victory: $0.47
Tampa Bay hopes to harness the energy of an energetic home crowd at Tropicana Field, though that environment failed to shift momentum in their favor on Monday. The Rays plan to open Tuesday’s contest with Griffin Jax, who was tagged with the loss during Game 3 of the ALCS. Nevertheless, the right-handed pitcher surrendered merely one run through the opening four frames prior to giving up two additional runs during the fifth inning. Tampa Bay utilizes an approach similar to Milwaukee’s—focusing on situational hitting and solid defensive play—yet their offense has faltered during this series. Facing elimination on home turf, Tampa Bay aims to secure a single win to stay alive. The SportsLine computer model projects a 41% chance for a Rays victory.
A Tampa Bay triumph trades at $0.47 per contract on Kalshi, representing a 47% chance according to current Brewers vs. Rays pricing. Execute trades on Kalshi with the leading Kalshi promo code CBSSPORTS55 to claim a $55 bonus:
Over 7.5 total runs: Yes $0.45, $0.56
Because each franchise relies primarily on two or three top starters, Game 4 will heavily depend on relief pitching right from the opening pitch. Jax recorded an 8-10 record alongside a 3.53 ERA during the regular campaign, though his ERA stands at 6.00 across two playoff outings. Milwaukee is expected to send Dustin May to start, who carries a 5.63 ERA across six postseason relief and starting stints. Both lineups feature dangerous sluggers, including Junior Caminero for Tampa Bay along with Milwaukee’s Jackson Chourio and Jake Bauers. Simulations from the SportsLine model indicate the combined score exceeds 7 runs in 61.9% of iterations.
Trading on the teams combining for over 7.5 runs sits at $0.45 per share on Kalshi, whereas predicting under 7.5 runs is priced at $0.56 per share. Create an account using the top Kalshi promo code CBSSPORTS55 to collect a $55 bonus:
