"It doesn't look like it's anything serious, but there's no reason 24 hours later to run him out there and have him make a start." Right-hander Jhoulys Chacin was scratched from a scheduled start Friday with back spasms and gave up two home runs in two innings Saturday night. Chacin, 25, is still expected to make his first career Opening Day start April 1 at Milwaukee. Weiss said he would like to see Chacin throw a couple of innings Saturday, either in the team's game against the Padres that night or in a Minor League game. This spring, Chacin has devoted himself to working on his fastball and changeup, and he has a 7.00 ERA in three Cactus League starts.
