The Chicago Cubs have suffered consecutive losses to the Arizona Diamondbacks. In the first instance, the Cubs lost 5-4 after a bullpen collapse, where reliever Daniel Palencia surrendered three runs in the eighth inning and a two-run home run by Ryan Waldschmidt secured the win in the ninth.

In the following game, the Cubs lost 2-0, a result influenced by a missed balk call in the sixth inning. Crew chief Alfonso Márquez later admitted the umpiring error, stating, “We just didn’t see it,” confirming that video evidence showed Arizona pitcher Eduardo Rodríguez had stepped off the rubber during his motion.
