SAN DIEGO -- The Cubs will adjust the rotation, the bullpen and the bench on Tuesday, with one of the moves being to designate left-handed reliever Phil Coke for assignment.
Coke had a 6.30 ERA in 16 games with the Cubs, giving up seven earned runs on 14 hits and three walks over 10 innings. Left-handers were batting .304 off Coke, while right-handed hitters were batting .389. The Cubs had signed the lefty to a Minor League contract on March 7.
The Cubs need to make room on the roster for lefty Tsuyoshi Wada, who will start Wednesday against the Padres, taking Travis Wood's spot in the rotation. Wood has been shifted to the bullpen after going 2-2 with a 5.59 ERA in seven starts. He made his first relief appearance on Saturday against the Pirates, pitching the ninth and picking up the save.
On Tuesday, the Cubs also are expected to send right-hander Brian Schlitter back to Triple-A Iowa and call up outfielder Junior Lake. On Saturday and Sunday, the Cubs were carrying 14 pitchers, which left manager Joe Maddon with three position players, and two were catchers.
Schlitter was 0-2 with an 8.10 ERA in nine games overall this season. He pitched in relief Saturday and Sunday against the Pirates.
This will be Lake's second stint with the Cubs. He was called up in late April and appeared in four games, going 4-for-14. He was batting .250 at Iowa.
A Major League source confirmed the moves Monday; the Cubs will make a formal announcement on Tuesday.
