Wells leaves camp to see blood clot specialist

BRADENTON, Fla. -- Pittsburgh Pirates starter Kip Wells was
examined Saturday by a St. Louis surgeon who specializes in blood

Wells left the Pirates on Friday night and was checked by Dr.
Robert Thompson, a vascular surgeon at Washington University,
general manager Dave Littlefield said.

Littlefield called the move "a precautionary measure" and said
he had no further details. Wells, who approached team officials
Thursday to complain of arm fatigue, is expected to rejoin the team
Sunday, Littlefield said.

Thompson has operated on two major league players, Colorado Rockies pitcher Aaron Cook in 2004 and Arizona Diamondbacks
outfielder Luis Terrero in 2003. Each needed to have a rib removed
and a vein redirected to remedy an affliction known as thoracic
outlet syndrome, one in which a vein from the chest to the arm is

Cook returned to playing baseball in eight months, Terrero in
five months.

The 28-year-old Wells is coming off a disappointing season in
which he went 8-18 with a 5.09 earned run average. The Pirates
signed him to a one-year, $4.15 million contract in January and
avoided arbitration.
