The competition for the final spot in the Rays' rotation is down to four candidates after Enny Romero and Alex Colome were optioned to the minors Saturday. Jake Odorizzi, Nathan Karns, Erik Bedard and Cesar Ramos are the four remaining options for the last spot in the team's rotation.

"You look at each one individually," manager Joe Maddon said, per MLB.com. "Let's say Odorizzi. Here's a guy vying for a job and he's out there working on a new pitch (changeup). It's a beautiful thing. And now he's made some progress with that.

"Karns had a little bit of a setback the other day [general soreness]. He came back and was throwing the ball well, kept the ball down. And Bedard had a nice outing his last time out. Bedard's velocity came up a little bit. Odorizzi's developing this other pitch. And Karns is just kind of interesting the way he throws the ball hard and down. That's what I've focused on with all three."
