The Cincinnati Reds defeated the San Francisco Giants 2-1 on April 14, 2026, at Great American Ball Park in a tightly contested, low-scoring affair that the DiamondIQ model's estimate opened at 54 percent in favor of the home side and closed at 100 percent. The Reds built their winning margin through a pair of solo home runs in the middle innings, with Spencer Steer connecting off Robbie Ray in the third and Sal Stewart following suit off Ray again in the fourth, each swing worth roughly 10.5 to 10.6 percent in win probability added. San Francisco's only answer came in the fifth, when Willy Adames launched a solo home run off Brady Singer that momentarily shifted the balance by 10.7 percent and briefly kept the Giants within striking distance.
The Giants' best opportunity to change the outcome arrived in the eighth inning, but it unraveled quickly. Luis Arraez opened the frame with a single off Tony Santillan, a hit worth 7.9 percent in win probability, putting San Francisco in position to threaten. That hope dissolved when Matt Chapman grounded into a double play, a swing of negative 16.4 percent in win probability that effectively extinguished the rally and represented the single most consequential play of the game. The Giants finished with seven hits but were unable to convert the necessary runners.
Brady Singer led all pitchers with 16.6 percent in win probability added, controlling the Giants' lineup through the heart of the game, while Emilio Pagán contributed 15.2 percent and Santillan added 10.8 percent to close it out. Among position players, Arraez finished as the top batter by WPA at plus 10.9 percent, followed by Matt McLain at plus 9.6 percent. Despite outpacing Cincinnati seven hits to three, San Francisco's inability to string together runs against a disciplined Reds pitching staff proved decisive.
