While the Cubs acquired swingman Jesse Chavez late Thursday night, I would be shocked if he’s the only addition Theo and Co. make at the deadline this year. Chaves is a 34-year-old right handed pitcher who’s a free agent at the end of the year, and it’s difficult to imagine him making much of an impact over the next two months. Assuming that the Cubs are not 100 percent confident in Justin Wilson, Brian Duensing and Mike Montgomery (if he returns to relief) as the only southpaws out of the pen, here are a few names that the Cubs could be eying here in the next 12 days.
