The Tampa Bay Rays defeated the Chicago Cubs 6-4 at Tropicana Field on April 6, 2026, with the DiamondIQ model's estimate of a home win moving from 54% before the game to 100% at its conclusion. The Rays built their advantage in bursts, with the critical sequence beginning in the second inning when Cedric Mullins hit a home run off Jameson Taillon that added 12.0% to Tampa Bay's win probability. Junior Caminero followed with another home run off Taillon in the third, contributing an additional 9.9%. The Cubs managed a brief foothold in the sixth when Ian Happ doubled off Ian Seymour for a 7.8% swing, and Nico Hoerner's single off Shane McClanahan in the second had provided an earlier 7.7% boost, but Chicago's offense produced only four hits on the night and committed one error.
The decisive blow came in the bottom of the seventh when Jonathan Aranda connected for a home run off Phil Maton, a swing worth 21.5% in win probability that effectively put the game out of reach. Aranda finished as the game's top performer by WPA at plus 20.9% with a RE24 of plus 1.4, while Mullins posted plus 6.5% WPA and Caminero plus 5.9%. The Cubs added single runs in the sixth and ninth but could not mount a meaningful comeback against a Tampa Bay bullpen that closed the game efficiently. Hunter Bigge led the Rays' pitching staff with plus 9.0% WPA, followed by Kevin Kelly at plus 5.9% and Bryan Baker at plus 2.4%, as Tampa Bay held Chicago to a four-hit effort and secured a clean win with no fielding errors.
