It's no secret that the Yankees have been unhappy with the backup first base options they have on the team. Well, duh. That's what you get for not actually having a backup first baseman on the roster in the first place. Kelly Johnson has been shaky, and they likely don't want to rely on Brian McCann, Carlos Beltran, Brendan Ryan, and whoever else. While it's probably very low on their list of needs, the Yankees might still be looking around for a better option, and that option might be John Mayberry Jr.
According to John Salisbury of SCNPhilly.com, "the Yankees are also a team to watch on Mayberry, a plugged-in major-league source said. They had a scout in Atlanta on Wednesday." The Red Sox are also said to be looking at him as outfield depth. Say what you will about his career .246/.308/.437 batting line, Mayberry has some value as someone who can play all three outfield positions and first base. The Yankees might have a full outfield, but they could definitely use his abilities at first; everything else would just be a bonus.
Aside from the fielding benefit, Mayberry would also give the Yankees a right-handed hitter off the bench who has hit lefties well, something they really don't have. He'd also come with three years of arbitration at the age of 30, making a potential cog in the longterm machine. The organization might have a few backup first base options in Peter O`Brien, Tyler Austin, and Jose Pirela, but in 2015 Alfonso Soriano and Ichiro Suzuki are gone, so Mayberry would be useful there as well.
In all honesty, I don't expect much to come of this rumor; who knows who the team was actually scouting, but it's worth to at least consider. The biggest hindrance to making this happen is the roster itself. With Kelly Johnson, Brian Roberts, Brendan Ryan, and Yangervis Solarte all in the infield mix, where would they make room for Mayberry? Unless they plan to cut Roberts soon (they don't), I don't see this one happening.
