NEW YORK — 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.He scored a run and went 1 for 4 with an RBI groundout as the designated hitter in his return from a broken ankle sustained in last October’s AL championship series opener. After icing the leg, the 39-year-old was headed to a hospital for a scan.In a season thus far memorable for sidelined stars rather than sustained success, the Yankees anxiously awaited the test results.“It’s not frustrating, yet.
