The Houston Astros are calling up prospect George Springer from Triple-A Oklahoma City on Wednesday.

The 24-year-old outfielder had 37 homers and 108 RBIs with 45 stolen bases combined in Double-A and Triple-A last year.

"It's just an indescribable feeling," Springer said. "I'm speechless right now."

Springer was selected 11th overall by the Astros out of UConn in the 2011 amateur draft.
