Braves' pitcher Tom Glavine is expected to throw off the mound on Saturday as he works towards returning from a strained elbow, according to The Associated Press. The session will mark the first time he's thrown off a mound since going on the disabled list on June 11. "After that, I don't know," Glavine said. "The key thing now is to get some arm strength. I don't know how long that's going to take." Said Manager Bobby Cox on Glavine's schedule, "It's going to be a while."
