Rookie of the Year possibilities has top prospect hopeful for callup

Pirates GM Neal Huntington has hinted around that a callup of top prospect Pedro Alvarez could be close and those close to Alvarez are hopeful for a late May callup which would give Alvarez Rookie of the Year possibilities.
The belief around the Pirates organization is that Alvarez will be called up no later than June 15, despite hitting just .250 in Triple-A Indianapolis.
Alvarez has 9 home runs and 36 RBI’s in 38 games.
Scouts will contend that Alvarez needs more time in the minors to improve his hitting against lefties but the Pirates have been pleased with his progress as a hitter and his improvement in the field at third base.
