The Yankees have called up eight players as September call-ups, bringing up Dustin Ackley, Andrew Bailey, Caleb Cotham, Rico Noel, James Pazos, Jose Pirela, Rob Refsnyder, and Austin Romine. Most of these players have already been up this year and are on the 40-man roster already, but a few–Bailey, Noel, Pazos, Romine–need to be added to the roster before they can play in the big leagues.
Ackley isn't as much of a call-up as he is really just an activation from the disabled list.
