With minor league spring training in full swing, I got my hands on the Yankees list of work groups this afternoon. For those who don't know, the work groups are simply the way the Yankees arrange their prospects for the day's prospect. There are four groups: Scranton, Trenton, Tampa and Charleston. Despite the names, the groups have absolutely no bearing on where a player will wind up once the season begins. 

After perusing the list this afternoon, I found three players of whom I simply had never heard. After a little research, however, I found out who they are:

Rigoberto Arrebato: This is a Cuban signee who just seems to have shown up without any fanfare, a la Yadil Mujica last year. From what I can gather, he's a left-hander who had a tryout with the Cardinals at some point, and has a cousin, Frank del Valle Arrebato, also left-handed, who also tried out.

Giovanny Gallegos: This appears to be the work of Lee Sigman, the scout who helps the Yankees pluck talent from Mexico. Gallegos, it seems, was part of a package of three players the Yankees signed this January out of the Mexican League. The other two, Luis Niebla and Jose Figueroa, do not appear on the work group lists. If you speak Spanish, this link will explain it.

Pedro Guerra: This one's a little easier. Guerra is a 22-year-old Venezuelan who pitched in the Twins' system last year. Between Elizabethton and Beloit, he went 4-2 with a 4.21 ERA in 66.1 innings. He fanned 80 against 18 walks. According to Baseball Reference, he's 6-foot and 180 pounds.

That's all I know about the trio, but I'll see them in Tampa in a few weeks.
