Jeff Samardzija is considered by some to be in line for a contract extension from the Cubs, but while the team discusses one with Starlin Castro, he gave no indication that he's doing the same.

"I'm not really too worried about that. I like to leave that front-office stuff to my agent," Samardzija said.

"That's what they do and that's what they are paid to do, to talk about that stuff. I'm here to play baseball and that's just what I'm going to do. When things like that happen it's kind of out of your control to tell you the truth. You can just prove to them that you are valuable on the field and whatever happens, happens."

In 23 starts this season, Samardzija is 8-10 with a 4.06 ERA and 141 strikeouts in less than 140 innings.
