CHICAGO — Backup catcher David Ross, who is out with a concussion, was cleared to start working out. He then threw, hit off a tee, and rode an exercise bicycle.
"The symptoms have resolved," manager John Farrell said. "We'll look to increase the intensity of the work tomorrow. So he's turning the corner."
When the Sox get back to Fenway on Friday, they'll decide whether Ross gets activated or plays in a minor league game or two.
• Farrell played and coached at Oklahoma State and he was following the news of the tornadoes there the last few days. "Our thoughts are with all the people," he said.
Will Middlebrooks also was following the news. His sister, Lacey, is a recent graduate of Tulsa University and his father, Tom, is from Oklahoma.
• Ryan Dempster played for the Cubs from 2004 until he was traded to the Rangers last July. This is his first time back in uniform in Chicago.
Dempster's children live in Chicago and he had his son, Brady, with him in the clubhouse.
• The Cleveland Indians are 26-17 under Terry Francona after beating Seattle today. Has Farrell heard much from his old friend?
"He's too busy winning," said Farrell. "I think everybody in baseball is watching. They have a very good team. They're playing with a heck of a lot of confidence."
The Indians arrive at Fenway Park on Thursday for four games.
