Jon Heyman of CBSSports.com reported the Yankees will send infielder Brendan Ryan and pitcher Adam Warren to Chicago in return for Castro.
Warren is a 28-year-old right-handed pitcher who played for the Yankees his entire four-year career. 2015 was his first year as a five-day rotation pitcher, going 7-7 with a 3.29 ERA and striking out 104 batters.
Versatility is what makes Warren valuable. The Cubs can move him into the fifth spot in the rotation or count on him for a relief role, as Joel Sherman from the New York Post noted:
Jesse Rogers from ESPNChicago.com thinks the opposite and believes Warren is meant to be just a bullpen guy or a fringe end-of-the-rotation pitcher:
Jeff Passan from Yahoo Sports thinks Warren is a good asset for the Cubs to obtain but that this deal was more so Chicago's attempt to replace Castro with Ben Zobrist, who signed with the Cubs on a four-year, $56 million deal on Tuesday, as Fox Sports' Ken Rosenthal first reported and the team later confirmed:
Warren is a young arm who could add some depth to a Cubs rotation that needs it at the back end. After Jon Lester and Jake Arrieta, the bottom of the rotation is unknown. If Warren has a good spring training, he could be in line for a fifth-day starting spot.
