Before dating Yankee slugger Derek Jeter, Minka Kelly struck out when it came to her knowledge of baseball.
“When I met Derek, I didn’t know anything about baseball at all,” Kelly says in a new HBO documentary, Derek Jeter 3K, which premiered last week.
“I didn’t know the difference between a run and a homerun,” the actress, who’s been dating Jeter since 2008, continues. “I thought if you made a connection with the ball, that was an automatic hit.”
