The Yankees have a recent history of making roster upgrades — minor upgrades, but upgrades nonetheless — in Spring Training, most notably landing Chris Stewart in 2012 and Shawn Kelley in 2013. There are still some decent free agents available and reportedly plenty of teams are still looking to swing trades. The opportunity to upgrade is there.
As Brian Cashman tells it, the Yankees are unlikely to make any moves prior to Opening Day. The GM told Brendan Kuty he “doesn’t anticipate anything in the short term,” though of course that could change in an instant.
