The versatile pitcher struggled in Chicago with an unusually high fly ball rate
In the previous offseason, the Yankees traded RHP Adam Warren and IF Brendan Ryan to the Chicago Cubs for 2B Starlin Castro. The versatile Warren had pitched well for the Yankees as a starter, and in relief, over the previous three seasons and was seen as a good fit for the Cubs, a team expected to contend for a championship. Only eight months later, the Yankees sent the hard throwing Aroldis Chapman to the Cubs for Warren and three prospects, including SS Gleyber Torres, who instantly became the Yankees top prospect.
