The Cubs have designated pitcher Randy Wells for assignment, according to Carrie Muskat of MLB.com (via Twitter). The club also announced that fellow right-hander Rafael Dolis has been recalled from Triple-A Iowa.
Wells allowed four walks in just three innings against the Mets on Tuesday, leading manager Dale Sveum to hint that he could be bumped from the rotation. In four starts and eight relief appearances this season, Wells has a 5.34 ERA with 4.4 K/9 and 7.5 BB/9. The 29-year-old also made six Triple-A starts, posting a 7.71 ERA with 6.5 K/9 and 3.6 BB/9.
