Colvin Makes Debut At First Base
Tyler Colvin made his major league debut at first base for the Cubs on Tuesday against the Diamondbacks.
He replaced Carlos Pena, who is dealing with a sprained right thumb.
Pena suffered the injury during Monday's 4-1 victory over the Diamondbacks on a play to his far right.
"I actually made the play in the seventh on a ball into the hole," Pena said. "As I threw the ball, I put my glove hand down and kind of jammed it into the ground."
