MIAMI — Jazz Chisholm Jr.’s gaffe at first base in the second inning, getting doubled off on a routine pop fly in the infield, wasn’t the only jaw-dropping mistake the Yankees made in Saturday’s ugly loss to the Marlins.

Following Sunday’s loss, Yankees manager Aaron Boone addressed the team’s poor outing. He had a three-word message that summarizes where his team is at following a third straight loss. “Gut check time,” Boone said, describing the urgency to turn things around at a crucial point of the season.
