Houston Astros outfielder Taylor Trammell appeared to hit his sixth home run of the season during a game against the Toronto Blue Jays, rounding the bases after connecting with a fastball to the deepest part of the ballpark. However, by the time he reached home plate, it emerged that the hit had not counted as the home run he believed it to be, turning his celebratory jog into a wasted effort. The mishap became a notable moment from an otherwise unremarkable loss for the Astros.

The incident occurred in the seventh inning of Monday's game, which Houston went on to lose to Toronto. Trammell struck the ball hard enough to think he had cleared the fence, and ran the bases accordingly, only for the outcome to be reversed or reassessed after he touched home. The mix-up added an embarrassing footnote to an already disappointing result for the Astros.
