DETROIT - Boston Red Sox right fielder Shane Victorino left Sunday's 7-5 loss to the Detroit Tigers due to tightness in his back.
Victorino was lifted for pinch hitter Daniel Nava in the eighth inning. The St. Anthony High School graduate slammed into the wall in foul ground in the fourth to catch a ball hit by Torii Hunter with two outs and the bases loaded.
"General soreness, general tightness," Boston manager John Farrell was quoted as saying on Major League Baseball's website. "He caught the ball and ran into the wall. That's why he couldn't swing the bat in his final at-bat. He's done that on a number of occasions. We'll get a full workup on him tomorrow."
Victorino missed seven games over a stretch of late April and early May because of a stiff back, and was examined at Massachusetts General Hospital after crashing into the Fenway Park wall on May 12 while pursuing a ball hit for a home run. Additionally, he has spent time on the disabled list this season because of a hamstring strain - he returned from that injury on June 8.
Victorino drove in a run Sunday on a fourth-inning groundout, giving him seven RBIs in his last six games. The 32-year-old, who is batting .285 this season, has 426 career RBIs - he needs six more to surpass Mike Lum for the most by a Hawaii-born player in major league history.
Nava remained in Sunday's game and was involved in a controversial play in the eighth.
Avisail Garcia lifted a fly ball to right field, and Nava appeared to have the ball in his glove, but when it came free second-base umpire Mike DiMuro ruled that no catch was made - the first of two errors against Boston that helped Detroit score three runs in the inning.
"I know I made the catch," Nava said. "Sometimes calls go your way, sometimes they don't."
A replay showed Nava might have lost the ball while transferring it from his glove to his throwing hand.
"To have a catch, you have to have complete control and voluntary release," said crew chief Ted Barrett, the third-base umpire. "(DiMuro) had him with control, but did not have the voluntary release. When he flipped the ball out of his glove, he never got it into his hand. That's not voluntary release."
Boston manager John Farrell was ejected for arguing the call.
"When you spend the rest of the game in the clubhouse, you probably have a difference of opinion," Farrell said. "Clearly, the call was missed. He caught it, he went to transfer to his throwing hand, dropped it at that point."
Joaquin Benoit (2-0) got the final four outs for the Tigers, although he allowed a run in the ninth.
Detroit won three of four games in the series.
"Sometimes it's your day, sometimes it isn't," said Tigers manager Jim Leyland.
Andrew Miller (0-2) threw wildly to first base for another error in the eighth.
