Michael Zegen owns more baseball caps than you’re likely to spot at a Yankee doubleheader; they hang in clusters, like rogue plants, around his one-bedroom apartment in the West Village.

Mr. Zegen, who plays Joel, the estranged husband of the title character in the Amazon series “The Marvelous Mrs. Maisel,” is pretty crazy about the national pastime. There you have reason No. 1 for his impressive cache of baseball haberdashery.

And now here is reason No. 2: Mr. Zegen, 39, labors under the quite mistaken impression that he can pop on a piece of brimmed headgear and go forth into the world, wholly unrecognizable to all who behold him.

Best of luck, pal, what with the long longed-for second season of the Emmy-winning “Mrs. Maisel” set for release on Dec. 5.
