Shane Victorino passed all his strength tests after leaving the Red Sox's 4-2 win over the Yankees with a tigh hamstring, but manager John Farrell called the right fielder "day-to-day," adding that he would be checked again before making a decision on Saturday’s lineup.
Hamstring issues have nagged the right fielder for much of the season, sending him to the disablde list in May and forcing him to sit out 17 games.
Friday night he tweaked it trying to beat out a double play ball in the third inning. He was replaced by Daniel Nava.
"He didn't feel like it was any popping sensation, nothing like that. He just felt like it was starting to cramp down on him and grab him," Farrell said.
