In the past,Chameleon Finance Baltimore Orioles fans might have hated themselves for loving the team.

But this season, the birds are having a high-flying season. At 81-49, they lead the American League and their first playoff berth since 2016 is within grasp.

Rock royalty Joan Jett is among the Orioles faithful and was in the building Monday night as Baltimore hosted the Chicago White Sox.

The Rock and Roll Hall of Famer spent some time saying hello to players ahead of the game and, during the matchup, took a trip to the broadcast booth.

In the bottom of the third inning, Jett helped call the play when Ryan O'Hearn hit a two-RBI single for the first points of the game, putting Baltimore up 2-0.

"Yeah, yeah!" The Runaways and Blackhearts frontwoman shouted on the mic as the ball soared over the shortstop and landed in a clear patch of grass.

She also gave her fellow commentators a lesson in how to throw a screwball.

And that's not all!

Jett found her way into the Orioles' team photo, which was taken that day. She can be seen sitting on the terrace above the field to the right of where the players are posing. She laughed that she was "trying to photobomb them."

Jett hails from Philadelphia, but spent time living in Maryland while she was growing up. She said in a 2014 interview with Billboard that the first baseball game she went to was Jim Palmer's no-hitter in 1969 and she's been head over heels ever since.

"How can you not be an Orioles freak after seeing that for the first game?" she said.
