4 best relievers available - 3. Wandy Peralta
Southpaw Wandy Peralta is another name the Cubs can swoop in for to make a dramatic acquisition to the bullpen. Regarding numbers, Peralta posted a 2.83 ERA, and although his FIP was alarming at 5.05, his batting average against was only .190. Mainly, this was due to him being in the bottom 5% of the league in BB%. However, he still owns a respectable 2.96 ERA combined in the last three seasons, so it's hard to argue too much.
Peralta throws four pitches in total. Three are above average, with his fastball/sinker combo and his changeup sitting in at least the 73rd percentile. He served as more of a setup man with the New York Yankees last season, but for the Cubs, he is the perfect compliment to Adbert Alzolay for manager Craig Counsell to utilize based on matchups late in ball games. The Cubs would be wise to swoop in here, even if they must up the ante and secure him on a multi-year deal.
