Baker said he would like to play on Sunday.
"It blew up and got purple right away," Baker said. "I was worried about it.
"Thankfully, the X-rays were negative. I'll ice it all night and get some treatment from our trainers and try to get out there as soon as possible."
Baker took a ball off of his hand during batting practice and was scratched from Saturday's lineup, in which he was penciled in to play third base.
