Gardner has been drawing a lot of interest this offseason and could eventually be traded for the right price. He hit .259 this year with 16 homeruns and 20 steals in 151 games, and is owed $38 million over the the next three years.
If Gardner is moved, the Yankees will presumably start Aaron Hicks in left field, who they acquired last week.
Castro provides a potential upgrade for the Yankees at second base.as they currently have a platoon of Dustin Ackley and Rob Refsnyder. Castro transitioned to the position this season and is a three time All-Star.
However, he disappointed this year with a .265 average and .671 OPS in 151 games.
Castro has been a trade target for the Mets for years, but the two teams could never work something out. The Cubs wanted the one of the Mets’ top young pitching prospects in return, which is something that Sandy Alderson and the front office refused to do.
