Red Sox relief pitcher Jeff Gray's condition continued to improve yesterday while doctors at Boston's Beth Israel Hospital tried to determine the cause of his collapse in the clubhouse.
Dr. Arthur Pappas, the team physician, said at a news conference that Gray took a few steps Saturday and walked down the hospital hall "with minimal support" yesterday.
Gray, 28, suffered dizziness, slurred speech and weakness in his right arm and leg after a routine pregame workout Tuesday in an attack described as similar to one he had 10 years ago at Florida State.
Tests, including CT scans and Magnetic Resonance Imaging, have failed to determine the cause of the seizure, Pappas said. An arteriogram, described as a study of blood vessels, is scheduled today.
* YANKEES: Pascual Perez made his minor-league rehabilitation debut with Class AA Albany-Colonie, giving up two hits in 2 1/3 innings against New Britain.
Perez, trying to return to the major leagues for the second time this year, threw 33 pitches, struck out two, walked none and allowed a run in a 5-4 loss.
* REDS: Pitcher Jack Armstrong was optioned to Class AAA Nashville, a little more than one year after starting the All-Star Game.
The Reds replaced Armstrong with Mo Sanford, a right-hander who started the season at Class AA Chattanooga and has spent less than a month with Nashville. It's Sanford's first major-league experience.
Armstrong's demotion completed a one-year fall from All-Star status. He was 11-3 at the All-Star break last year, but has gone just 7-16 to lose his spot in the rotation and, finally, his spot on the club.
"There's nothing really to say," Armstrong said. "I've just got some work to do, things to do better. I just want to leave it at that. I'll go down and give it my best shot."
