In a historic moment for baseball, brothers Willson and William Contreras both homered in the same inning during the St. Louis Cardinals' 8-5 victory over the Milwaukee Brewers. The ninth inning saw Willson, playing for the Cardinals, hit a solo home run, followed closely by William's homer for the Brewers. This marked the first time in 90 years that brothers have homered as opposing players in the same inning, a feat last accomplished in 1933.

The Contreras brothers' competitive spirit was palpable, as Willson exchanged no words with William as he crossed home plate, despite their familial ties. William, however, remarked on the competition saying that during the game, they are just that—competitors.
