More on the prospects headed to Miami from CBS Sports:
Augustin Ramirez, 22, has split the season between Double- and Triple-A, hitting .269/.358/.505 with 20 home runs. Ramirez is considered to be a bat-first backstop with good power. He needs to work on his defense, however, and the Yankees have cross-trained him at first base, suggesting they weren't completely sold he'd stick behind the dish.
Serna, 22, has hit .253/.341/.444 with 13 home runs and 11 stolen bases in 88 games at High-A. He's an offense-first player who has experience at second and third base and shortstop, in addition to some time spent in the outfield.
The other Ramirez, 19, has hit .348/.447/.513 with nearly as many walks as strikeouts in the Florida Complex League.
