SCOTTSDALE, Ariz. Giants manager Bruce Bochy said RyanVogelsong would test his strained lower back by playing catch on Sunday, butthe right-hander plans to take an additional 24 hours to make sure hes right.Vogelsong was encouraged after doing a sequence ofrotational exercises on Saturday the first time hes tested his range ofmotion since injuring himself while doing power squats earlier this month.We had no issues, Vogelsong said. Well make sure thisthing is knocked out. One more day of these exercises with no setbacks and Illbe out there.Bochy said it looked like Vogelsong was getting to the tailend of his back issue and likely would get on a mound in another week. Hestill has enough time this spring to build requisite arm strength, but anothersetback could endanger his ability to be ready.The Giants also continue to operate with an abundance ofcaution with Tim Lincecum, who was the only pitcher to throw a side sessionSaturday. Trainers brought him in the clubhouse early rather than have him standon the field for the entirety of Saturdays workout.Buster Posey caught Lincecum and said the two-time Cy YoungAward winner showed no signs of discomfort.He lookedgood, Posey said.
