ST. PETERSBURG, Fla. -- Rookie outfielder Andrew Benintendi left Wednesday's game with a knee sprain and will be further evaluated Thursday.
Benintendi was on second base in the seventh inning, with teammate Travis Shaw on third. The Tampa Rays pulled the infield in, and with no out, Dustin Pedroia hit a grounder to short.
Initially, Benintendi was intent on getting to third, but with the infield in, Shaw didn't break from third. That forced Benintendi to head back to second. Tampa shortstop Matt Duffy chased him back to the bag and tagged him out. As he attempted elude the tag, Benintendi's left leg buckled underneath him.
He fell to the ground and got up very gingerly. Benintendi was helped off the field by two members of the training staff, unable to put any weight on the left leg.
"Right now, it's just stiff," explained Benintendi. "We're just going to come back tomorrow and see how it feels.
"It was bad baserunning. It shouldn't have happened. I shouldn't have made a move toward third base. That was my mistake."
Manager John Farrell said the team is trying to get an MRI scheduled for Thursday, but they hope to have more information so they can make a roster decision.
"We're still in the works of getting the appropriate information," explained Farrell. "if we have to make a (roster) move, based on that MRI finding, we'll do so. It's an unfortunate situation with a guy who's been doing a great job for us.''
"That hurt. That kid's been doing so good for us," said David Ortiz. "Losing him that way. . . the way they took him off the field, it seemed like it wasn't good. Let's see what they say. Hopefully, it's (just) a couple of days thing."
One thing that might indicate how painful the knee injury was: until he saw the video, Benintendi was unaware that he had also rolled his left ankle.
"Yeah, I watched the replay," he said. "But I didn't even realize I did that, so, I guess I did.''
Only two nights earlier, Benintendi had made one of the best catches of the season when he leaped above the wall in left to prevent a two-run homer by Rays outfielder Steve Souza Jr.
Benintendi was 1-for-3 with a double Wednesday and is hitting .324 after being promoted from Double A to the big leagues three weeks ago.
