NEW YORK -- One day after setting a Red Sox franchise record for most stolen bases in a game, Jacoby Ellsbury was scratched from Friday night's game against the Yankees because of tightness in his left groin.
Ellsbury, who was in the original lineup before being removed, said he felt he felt the groin tighten after the record-setting steal of second base in the eighth inning Thursday night in Philadelphia.
"It tightened on me," said Ellsbury. "I just want to play it safe today. It's day to day; we'll see how it is tomorrow. I got in here early and got some treatment, but it continued to stay tight. I want to be careful so it doesn't get worse. I just want to do the right thing so it doesn't get worse."
With Ellsbury sidelined, the Red Sox shifted left fielder Daniel Nava to the leadoff spot in the batting order and replaced Ellsbury in the field with Jackie Bradley Jr., who will be making his first major-league start in center field Friday night.
"It kind of tightened up right when I [stole the base]," said Ellsbury. "You could see me kind of jogging to third (when the catcher's throw went into the outfield)."
The setback comes as Ellsbury has begin to heat up. Thursday night against the Phillies he reached base five times (three hits, one walk, one hit by pitch), and had multiple hits in four of his last five games.
