Extra bases

• Third baseman Luis Valbuena was back in the Cubs lineup on Sunday, after missing two games because of a sinus infection.

Valbuena, who had five hits in his last 44 at-bats (.114) entering Sunday, told Renteria he was feeling better.

"[Saturday], he was taking ground balls and working extremely hard," said Renteria, "and came out and said, 'Hey, I'm ready to go.'"
