Wesneski (forearm) began a rehab assignment with Triple-A Iowa on Sept. 6 and has given up three earned runs on seven hits and two walks while striking out seven across five innings over his four appearances.
After throwing two scoreless innings for Iowa on Tuesday, Wesneski could be on the cusp of activation from the 15-day injured list. According to Ryan Herrera of AllCHGO.com, Wesneski was spotted in the Cubs' clubhouse Wednesday, which suggests his rehab assignment has come to an end. Once he's formally reinstated, Wesneski will likely serve as a multi-inning option out of the bullpen.
