ANAHEIM, Calif. -

The Minnesota Twins surprised many by calling up 20-year-old shortstop Jorge Polanco from Class A Fort Myers on Thursday, giving the club some depth at the position with the injury to starter Danny Santana.

Santana twisted his left knee running out a double on Wednesday and is listed as day-to-day.

Polanco was hitting .289 with five homers and 35 RBIs in 72 games for Fort Myers, and might be returning to the minors shortly if Santana's knee feels better soon.

While Polanco is up with the big club, manager Ron Gardenhire said he has no problem using Polanco, who is the second youngest player in the majors (Texas' Rougned Odor is five months younger).

"I saw him in spring training, and we all know he's very talented," Gardenhire said. "He can swing it. He's a little loose defensively, which some young players happen to be. But he has a lot of really good skills, so it's exciting."

Polanco got his first major league plate appearance as a pinch hitter in the ninth inning and walked on four pitches from Angels reliever Ernesto Frieri.
