It’s no secret that the Chicago Cubs will be pursuing reinforcements in the bullpen at the trade deadline. They've been connected to some big arms so far, like Jhoan Duran of the Twins and David Bednar of the Pirates. All of these would be massive improvements to a unit that has seen some regression of late. One thing they could seriously use, though, is another lefty.
A southpaw hasn't been a serious need for a while now. After a brief, shaky start, Caleb Thielbar has been among their most dominant arms this year. The real feel-good story, however, has been Drew Pomeranz.
