From Yahoo's fantasy baseball player notes:

May 23 The Cubs instructed pitcher Carlos Zambrano to cut back on his computer time because the hours he's spending typing could be contributing to his elbow problems, according to the Associated Press. This came about after Zambrano had to leave his May 14 start against Washington early with a sore elbow that the team determined was the result of a non-pitching condition and activity. "I have to spend one hour and take it easy," Zambrano said, after it came to light that he had been spending as much as four hours a day communicating via e-mail with his brother.
