Dontrelle Willis' first appearance in a Chicago Cubs uniform came to an abrupt end. The much-traveled left-hander hopes his latest comeback attempt does not meet a similar fate.

Willis came on in relief in the eighth inning of the Cubs' 7-6 loss against the Los Angeles Dodgers and walked leadoff hitter Nick Evans, then left with tightness in his left shoulder after throwing one pitch to Brian Barden.

"It's a mild setback, I guess. Hopefully it's nothing serious and I don't miss a lot of time,'' said Willis, who will be reevaluated by the Cubs medical staff. "It's probably just fatigue. Hopefully just a couple of days and I'll get back on it. I'm going to go back to the yard and let them give me some TLC.''

The 2003 National League rookie of the year with the then-Florida Marlins, Willis is trying to make a comeback with the club that drafted him out of high school in 2000.
