Yanks call up Kevin Whelan

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.

He was acquired by the Yankees in 2006 as part of the blockbuster trade which sent slugger Gary Sheffield to the Detroit Tigers.

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.

Currently, the Yankees' patchwork bullpen includes steady right-hander David Robertson, future Hall of Famer Mariano Rivera and pleasant surprise Luis Ayala, but not much else.

Left-hander Boone Logan has been unable to retire left-handed hitters, while Jeff Marquez, Lance Pendleton and Amauri Sanit are -- for the most part -- unknown and inexperienced.

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.
