ST. PETERSBURG, Fla. — Whether Jazz Chisholm Jr. could have pulled off a double play if he had fielded the ball cleanly in the bottom of the 10th inning Saturday night remains up for debate.

So, apparently, does his knowledge of the rulebook.

While talking through his thought process on the play — with one out and the bases loaded in a tie game, he cost himself a chance at a tag-and-throw double play because of a bobble — Chisholm wondered aloud if he could have thrown to first and then tried to get the runner at second on a tag play for an inning-ending double play, admitting, “I don’t know what the rule is.”

Sitting at the locker next to him after the 5-4 loss, Trent Grisham informed him that the runner would have scored from third before the tag at second base, thus ending the game anyway.

Sunday morning, manager Aaron Boone insisted that Chisholm does, in fact, know the rule.

“We’ll talk through it,” Boone said before the Yankees got swept by the Rays at Tropicana Field. “He’s not confused on it. I think that’s kind of the default answer when he’s got [reporters] in front of him. Look, it turns out to be a tough play. Watching it back, there might have been a chance to where if he gets it cleanly, he gets the tag off, it’s hard to know how exactly [Yandy] Díaz reacts in that moment [running from first to second]. Once it chops like that, you know it’s going to be a tough one to turn the normal 4-6-3.”

Asked directly about Chisholm saying he didn’t know the rule, Boone replied, “I think he knows the rule.”

Chisholm, who is in the minority in that he typically does not just give canned answers to reporters, has been crushed on social media for saying he did not know the rule.

“Look, I think part of it comes to answering those things in a better way,” Boone said. “You guys are around — Jazz is not a dumb guy. So it’s just sometimes how you present yourself in certain situations, coupled with he’s off to a little bit of a slow start too. Some good play changes that narrative.”

After going 1-for-4 with a double Sunday, Chisholm finished the day batting .179 (10-for-56) with a .501 OPS through 15 games, a rough way to start a contract year with plenty hanging in the balance. He lamented that he has been popping everything up no matter what he does, saying, “I just can’t not hit the ball 50 degrees up.”

Of course, Chisholm is not alone in struggling at the plate, but the Yankees could certainly use the kind of production he had last season, especially during this rough stretch.

“Jazz is going to hit. Jazz will get it going,” Boone said. “Right now, it’s just working on getting that ball on a line. Once he does that, he’ll take off as well.”
