Renato Nunez, a 3B for Oakland is the biggest name so far. He signed with Oakland for 2.2 million dollars. His biggest asset is his bat. He will need some time to grow into his power, but he has a nice swing and doubles should come easy to him.
Yoel Araujo is an athletic CF who signed with the Rays for 800k. He has a big body structure and will probably end up as a corner OF'er. He has a good bat and that is his best tool.
Some other players have signed Danry Vazquez, OF,DET(1 millionish) and Jose Tovar, LHP, COL for 350K.
Kinda slow to start but that is the way the international signings go.
