Tampa Bay Rays at Chicago Cubs: Final Score & Recap

The Chicago Cubs defeated the Tampa Bay Rays 2-1 at Wrigley Field on May 30, 2023, in a tight, low-scoring contest that the DiamondIQ model's estimate found decidedly one-sided by the end despite giving Chicago just a 30 percent pre-game win probability. The Cubs scored once in the first inning and added their decisive run in the sixth, while Tampa Bay's lone run came in the fifth. Kyle Hendricks worked efficiently enough for Chicago, and the bullpen closed the door without incident, with Adbert Alzolay leading all pitchers with a plus-25.9 percent win-probability contribution, followed by Hendricks at plus-22.5 percent and Mark Leiter Jr. at plus-8.5 percent.

The game's most consequential sequence came in the bottom of the sixth inning against Shane McClanahan. Ian Happ opened the frame with a double worth plus-8.2 percent in win probability, and Mike Tauchman followed with a single that added another plus-12.4 percent, providing the margin that would hold as the final difference. On the Tampa Bay side, the opportunity to shift momentum never fully materialized. Francisco Mejia grounded into a double play in the second inning, a swing of minus-12.1 percent, and Trey Mancini's ground-ball double play in the eighth erased minus-10.9 percent of win probability, effectively sealing the Cubs' victory. Randy Arozarena's fifth-inning single off Hendricks, adding plus-10.9 percent, accounted for the Rays' most impactful offensive moment but ultimately proved insufficient.

Happ finished as the game's top batter by WPA at plus-14.6 percent with a RE24 of plus-1.2, and Tauchman was close behind at plus-13.2 percent and plus-1.0 RE24. The Cubs held Tampa Bay to one run on seven hits without committing an error, mirroring Chicago's own clean defensive effort, and the DiamondIQ model's estimate reached 100 percent certainty by game's end, a reflection of how thoroughly the Cubs controlled the late innings despite entering as a decided underdog.
