TORONTO -- Rangers outfielder Nelson Cruz may miss the rest of the three-game series with the Blue Jays because of tightness in his left quadriceps muscle.
Cruz left Friday's 3-2 loss in the fifth inning when the muscle tightened up on him. This was the first of three games for the Rangers on the artificial turf at Rogers Centre, and Cruz missed 16 days in May because of a strained right quad.
The Rangers expect Cruz to be ready when they play in Detroit on Tuesday, but they aren't likely to take a chance with him on the unforgiving turf in Toronto.
"We weren't going to take a chance, especially on this turf," Rangers manager Ron Washington said. "You may not see him tomorrow. You may or you may not."
Cruz had given the Rangers a 1-0 lead in the second inning with a home run over the left-field fence. It was his 23rd home run of the season. He struck out in the fourth inning. When the Rangers went to the field in the bottom of the fifth, Endy Chavez had replaced him.
Cruz said he felt the muscle tighten on him doing nothing more than playing catch with the bat boy while warming up for an inning. He said this does not feel as bad as the injury in May.
"It's just tight," Cruz said. "It's a precaution because we don't want it to get any worse. When I walk around, I don't feel any pain."
