NEW YORK — Jacoby Ellsbury stole second base with two outs in the eighth inning Thursday night and the Red Sox leading the Philadelphia Phillies by five runs. It gave him five steals in the game, a new team record. But it also left him with an injury.
Ellsbury was scratched from Friday night's lineup with tightness in his left groin, the result of the final steal.
"It tightened up on me," he said. "I just want to play it safe today."
Ellsbury said he felt pain when he broke for second base. He stole the base easily and then went to third when the throw from Phillies catcher Erik Kratz went into center field.
Ellsbury was walking cautiously in the clubhouse. He said he wasn't sure about playing Saturday.
"We'll go day-to-day, we'll see how it is tomorrow," he said. "I got in here early and got all the treatment and everything. It stayed tight. I want to do the right thing so it doesn't get worse."
Jackie Bradley Jr. will replace Ellsbury in center field in tonight's series opener against the Yankees. Daniel Nava will take Ellsbury's spot as the leadoff hitter.
Manager John Farrell said Bradley would play center field for as long as Ellsbury is out.
"We're expecting this to be a day-to-day and hopefully not too long of a situation," Farrell said. "We'll treat it accordingly."
Ellsbury is 16 of 40 (.400) in his last 10 games with eight walks.
"I always want to be in there, especially a game like this," said Ellsbury. "It's always fun to play. Take care of it and shouldn't be a problem."
