SCOTTSDALE, Ariz. (AP) _ San Francisco Giants pitcher Danny Darwin was hit in the right knee by a line drive Monday during an exhibition game against Oakland and carried off the field.

Darwin was taken to a hospital across the street from Scottsdale Stadium, and X-rays were negative. He was expected to be sore for the next several days, Giants trainer Mark Letendre said.

Darwin, 42, was hit in the knee by Mike Blowers' line drive in the sixth inning. He fell to the mound, clutching his leg, as the Giants' trainers ran from the dugout.

Giants manager Dusty Baker and A's manager Art Howe also went to the mound. After several minutes, Darwin was carried off and replaced by Chris Brock.

``That was frightening right there,'' Baker said. ``It looked like it was real serious.''

Darwin's right knee was wrapped in ice in the Giants' clubhouse before he was put in a waiting ambulance. He was taken to Scottsdale Memorial Hospital, accompanied by his wife and three daughters.

Letendre said the ball hit Darwin on the inside of the right knee.

``Danny's going to be stiff and sore for the next few days,'' Letendre said.

Immediately following the hit, Darwin's younger brother Jeff expressed concern.

``He wanted to walk out of here, I guess that's kind of a good sign,'' said Jeff Darwin, who also pitches for the Giants.

Howe, who worked together with Danny Darwin in Houston, said he rarely goes on to the field when a player from the other team is injured, but he was especially concerned about the veteran right-hander.

``He's a great guy, a great competitor, and that's his bad knee,'' Howe said. ``I'm thankful it didn't hit the kneecap.''

Darwin, a 19-year veteran, was acquired by the Giants last season in a nine-player deal with the Chicago White Sox.
