This was supposed to be a golden, glorious week for New York baseball fans.

The Mets are in the playoffs! The Yankees are too! A fated Subway Series, the first time the teams would be meeting in the World Series in more than two decades, is but a few wins away. You’d think fans would be happier than a kid in Cooperstown.

But then, on Monday, Mayor Eric Adams marched down Fifth Avenue during a Columbus Day parade, wearing a baseball cap that pleased exactly zero New York sports fans.

The hat featured a Mets logo on the right side and a Yankees logo on the left. If there’s no crying in baseball, to Mr. Adams there’s apparently no picking of sides either.

At the moment, as he’s facing federal charges and a sinking approval rating, the mayor’s fair weather hat seemed to be an I’m-With-You plea to baseball fans of all five boroughs.

“I’m like everyday New Yorkers,” Mr. Adams told reporters on Monday, with the curved brim cap situated on his head.

Fabien Levy, a spokesman for the mayor, said that the hat captured a mayor caught between his personal fandom and his political duties.
