Take Caden Cole out to the ball game.

Before the Yankees dominated the Tampa Bay Rays in Game 1 of the ALDS on Monday, Gerrit Cole’s wife Amy was photographed at Petco Stadium in San Diego, where she held the pitcher’s No. 1 fan: his 3-month-old son.

Repping Cole’s “45” on her navy blue cap and jacket, Amy — who has been married to the Yankees ace since 2016 — made sure young Caden also sported his pinstripe pride, wearing a mini jacket to match his mom’s.

Last week, Caden took in his first-ever baseball game at Progressive Field in Cleveland, where the Yankees defeated the Indians in the American League wild-card series.

“Caden’s first game was one for the books,” Amy posted to Instagram at the time.

As for Monday’s outing, the Yankees torched the Rays, 9-3, with Cole pitching six innings.
