Only Mesa and Almonte are on the 40-man roster. The others are Spring Training invitees.
When I look at this list I see the experience in Diaz and Rivera but I also see the hard work that Mesa and Almonte have put in as Yankee farmhands. In fact, I am partial to Mesa who I saw play at single A Staten Island several years ago. I also like the fact that he decided not to play in the World Baseball Classic because he really wants to be in left field on Opening Day.
It would be fun seeing a new Melky in the outfield, even if it is only for six weeks (and even if if the original one did turn out to be a bad guy). My cries of "Bring back the Melkman" would finally be answered and, as long as he doesn't forget to touch third base again, I'll be a happy woman.
