Derek Jeter walked to home plate, toyed with his batting gloves, stepped into the batter's box as fans chanted his name and legged out an infield hit. A feeling of normalcy returned to the Yankee Stadium. The captain was back after a nine-month layoff. But, perhaps, only for a few innings. Jeter singled on his first pitch of the season, then felt a tight right quadriceps and was pulled for a pinch-hitter in the eighth inning of New York's 8-4 victory over the Kansas City Royals on Thursday.
