With one out, Lorenzo Cain sent a hopper to Sandoval, who reached over in a unsuccessful attempt to catch Alcides Escobar off the third-base bag. When Escobar didn't budge, Sandoval turned and overthrew to first base, extending his leg and crumpling to his knee in obvious pain.
Sandoval rose after a few minutes and seemed to try walking it off before returning to the dugout under his own power. Travis Shaw replaced him at third.
"I thought he still had a shot," Farrell said. "It's a one-hop play that his momentum was taking him into the runner. He tags him, tried to correct himself, and deliver a throw across the infield, but I think if he makes the throw on line, he's got a chance to knock down the out."
Both players underwent X-rays, which Farrell said did not indicate fractures or any structural damage.
"It's pretty sore right now, but I'll be fine," said Swihart, who also said he didn't foresee a trip to the disabled list.
"That's not my decision, but it's just sore, that's all."
