After Mike Mussina learned he’d been elected to the Hall of Fame, he said he would have a hard time choosing which cap to put on his plaque, since his career was evenly split between The Bronx and Baltimore.

In the end, Mussina decided to go with neither.

The Hall of Fame announced on Friday that Mussina, along with Roy Halladay, will have blank hats on their plaques in Cooperstown.

“Both the Yankees and the Orioles were instrumental in my reaching Cooperstown,” Mussina said in a statement. “I am proud to have played for these great organizations, in front of the tremendous fans in Baltimore and New York, and I am honored to have the opportunity to represent them both in the Hall of Fame.”

Mussina was drafted by the Orioles and spent the first 10 years of his major league career with the organization before he signed with the Yankees and pitched for them for eight seasons.

The right-hander had slightly better overall numbers with Baltimore, but pitched in more postseason games with the Yankees and had his lone 20-win season — his last — in The Bronx.

During a press conference on Wednesday, Mussina called his situation “unique.”

“I almost split my career down the middle between the two organizations,’’ Mussina said Wednesday. “Right now, I couldn’t sit here and choose between one or the other. They were both instrumental to me sitting here. … We’ve got a little bit of time here to talk it over with the Hall of Fame and with the people there. I think we’ll come to the right decision, whatever it is.’’

Halladay, who was killed in a plane crash in 2017, spent the first 12 years of his career with the Blue Jays — with whom he won a Cy Young Award — but only pitched in the playoffs with the Phillies.

Mussina’s former teammate, Mariano Rivera, obviously, will enter as a Yankee.
