Extra bases

Anthony Rizzo and pitcher Jeff Samardzija combined on three straight defensive plays in the seventh inning on Friday, and the first two were pretty impressive stops by the first baseman.

"I think we've seen enough out of Riz at first to know he's a premium first baseman defensively," Samardzija said. "I always need to be on my toes when the ball heads that way, because he plays deep and plays in the hole. We're kind of on the same page. I'd rather have him cover a lot of ground.

"We've made that play a lot of times," Samardzija said. "It's nice to have that over there. It's a nice commodity to have a first baseman who can pick it like Riz."

• Looking ahead to the Cubs' series against the Diamondbacks, Travis Wood will start Monday and Jason Hammel on Tuesday. Wood and Hammel had both pitched Wednesday in the Cubs' doubleheader against the Yankees.
