Extra bases

The Cubs have played two extra-inning games this season, and even though they have six quality starts in the first nine games, the bullpen has been busy.

Chicago's relievers rank sixth in the National League in innings pitched with 32 1/3 heading into Friday's game against St. Louis.

Renteria said they're keeping tabs on how much work the relievers get. Justin Grimm and Hector Rondon are tied for eighth in the NL in innings pitched with six each, while Brian Schlitter is right behind with 5 2/3 innings.

One pitcher who hasn't gotten much work is lefty Wesley Wright, who has been in two of the nine games, and last pitched April 4.

"Wesley is up and ready to go," Renteria said Friday. "We haven't used him, but he's available."
