NEW YORK -- The New York Yankees have summoned right-hander Kevin Whelan from Triple-A Scranton/Wilkes-Barre, adding another fresh arm to their depleted bullpen.
In a corresponding roster move, outfielder Chris Dickerson has been sent down to Triple-A.
The 27-year-old Whelan, who was called up before Friday night's game against the Cleveland Indians at Yankee Stadium, was 1-1 with a 1.67 ERA and 18 saves for the Yankees' International League affiliate.
The Yankees, who are already without setup man Rafael Soriano and left-handers Damaso Marte and Pedro Feliciano, were dealt a devastating blow on Thursday when they learned that 25-year-old Joba Chamberlain has a torn ligament in his elbow and will require Tommy John surgery.
To clear room for Whelan on the 40-man roster, the Yankees moved Chamberlain to the 60-day disabled list.
General manager Brian Cashman said Thursday that the organization is unwilling to call up highly-touted Double-A prospects Dellin Betances and Manuel Banuelos.
The 29-year-old Dickerson was batting .357 with three RBIs in 15 games for the Yankees.
