It looks like UM landed one hell of a softball player and home run slugger here. She was ESPN California All-State as multi-purpose player.  She's also a pitcher. 

According to Strictly Softball, Ms. Gardner is apparently the "take no prisoners" type:

"Mandy earned a 0.43 earned run average, 91 strikeouts and 14-2 record through 97 innings pitched and batting .476 with 15 home runs and 27 runs batted in.  Gardner was named the South Coast League MVP and led Aliso Niguel High School to the league championship."

Aliso Niguel's High School mascot:  The Wolverines, of course.

And uh, about those home runs:  l'd like to hereby advise all softball fans in Ann Arbor and around the Big Ten conference to please park their vehicles well away from the outfield fence.  Thank you.
