Russell, who is 1-2 with an 8.00 ERA in two starts with the Cubs, giving up eight earned runs over nine innings, was expected to start Tuesday against the Rockies. Only this time, the Cubs will give him a little more time to prepare.
Before his last start against the Padres on April 20, Russell pitched in two games in relief against the Rockies. This time, they'll have the lefty do a side session just like the other starters.
"The one thing we're going to try to do ... is instead of pitching him an inning or giving him a few hitters before his next start, we're going to try to stay away from him," Cubs manager Mike Quade said. "We'll let him prepare and maybe change his repertoire a little bit, particularly against right-handed hitters and give him his best chance to be successful."
Right-handers are batting .469 against Russell while lefties are hitting .111, so Quade hopes the side session will give the pitcher a chance to fine-tune his stuff.
Russell is subbing for Andrew Cashner, who is rehabbing from a strained right rotator cuff and just began his throwing program on Friday. There's no timetable for Cashner's return.
