ST. PETERSBURG, Fla. -- The Red Sox said Thursday that they still don't have a definitive diagnosis on Andrew Benintendi's injured left knee -- but they know enough to place the rookie outfielder on the disabled list.
Benintendi underwent an MRI Thursday morning and the results were being sent back to the Red Sox medical staff in Boston -- led by team orthopedist Dr. Peter Asnis - to be reviewed.
Marco Hernadnez was recalled from Pawtucket to take Benintendi's spot on the roster.
"The initial read down here was enough to place him on the disabled list,'' said John Farrell. "To what severity the injury is, I don't have that exactly. That will be determined after the review by Dr. Asnis and people back in Boston.''
Benintendi injured his knee on the basepaths in the seventh inning of Wednesday's 4-3 loss to Tampa Bay. The outfielder attempted to elude a tag and return to second base when he wrenched his knee and rolled his ankle.
Asked if Benintendi's injury could be season-ending, Farrell said: "That's probably too early to tell. We're hope that it's not. We've just got to wait and see what comes out of this. And then depending on the findings, what is the safest thing for Andrew to get him back on the field. Optimistically, it's still this year.''
Farrell said there's little swelling and that Benintendi slept fairly well. He also noted that the ankle -- which he rolled -- isn’t a problem.
"Those are the positives,'' he said.
Boston has used seven players in left field this year -- Benintendi, Chris Young, Brock Holt, Blake Swihart, Rusney Castillo, Ryan LaMarre and Bryce Brentz.
Benintendi, Young, Swihart and Holt have all spent time on the DL, leading the manager to refer to the position as a "kind of a Bermuda triangle unfortunately...it's been little bit of a dark hole.''
Farrell said Young will get the majority of playing time in left, according to Farrell. Holt will also see some playing time, though he won't necessarily play against all right-handers.
Hernandez, meanwhile, will serve as another utility option in the infield.
"We'll mix and match out there,' said Farrell. "But CY will probably get a good portion of the at-bats [in left].’’
Farrell added that, regardless of who gets the playing time in left, the Sox need others in the lineup to step forward.
"We need guys to revert back to their normal contributions,'' Farrell said. "We've been in a dry spell of late...We've got a few guys who are in a little bit of rut since the All-Star break.''
Shortstop Xander Bogaerts is an obvious example, having gone just 10-for-41 on the long road trip. Jackie Bradley is another who's slumping, with just six hits in his last 36 at-bats. Finally, Travis Shaw is 3-for-20.
