Yankees shortstop Derek Jeter, on the 15-day disabled list because of a strained right calf, took batting practice on the field for the first time and started a running program Monday. Jeter took 30 swings in batting practice and fielded seven grounders on the grass before rain forced a stop. After a brief delay, Jeter returned to the field for three light sprints and some agility-related drills. "Everything's good," Jeter said. "Steps in the right direction."
