Veras says his oblique started hurting him "a couple days" ago but he "didn't pay attention to it." He appeared in Thursday's game against the Arizona Diamondbacks, giving up two home runs in an inning of work.
"I felt I could pitch with that," he said Saturday afternoon. "The next day I said, 'Oh, my God, it's just not a little (thing).' "
Veras has struggled since signing a one-year deal with the Cubs in the offseason. He has a 15.88 ERA in six appearances and lost the closer role after blowing his first two save opportunities. He was asked if the DL stint might give him a chance to clear his head.
"Maybe," he responded. "Who knows? At the same time I don't want to be in a position not to help the team win ballgames. Hopefully, when I come back, I can start over."
Manager Rick Renteria added: "You give yourself a little distance, maybe it will clear his mind a little bit."
This will be Schlitter's second stint with the Cubs after breaking camp with the team at the beginning of the month. He's appeared in six games this year, giving up four runs in 5 2/3 innings.
