Aaron Brooks

The Cubs acquired Brooks from Oakland for Chris Coghlan in February, but he was never healthy in 2016 after landing on the disabled list with a hip contusion in early April. Despite efforts to get back in the mix at Iowa, Brooks was limited just five appearances -- four starts -- in the Pacific Coast League before he was moved to the 60-day DL in August. In his last healthy campaign (2015), Brooks was effective as a starter at Triple-A, relying on good control to survive in the hitter-friendly PCL, but his limited exposure to big league hitters yielded poor results (6.67 ERA, 1.46 HR/9). Brooks remained on the Cubs' 40-man roster at the start of the offseason, suggesting that the front office sees him as a useful organizational piece, perhaps capable of contributing in long relief or as an option to make spot starts while working mostly as a starter at Iowa if he's able to return to health in 2017.
