Red Sox left-hander Eduardo Rodriguez left Saturday's start against the Blue Jays after colliding with a runner at first base, ending what had been his most efficient outing of the season.
The team announced that he suffered a sprained right ankle. X-rays were negative, but he'll undergo further evaluation.
Rodriguez had been dealing to that point with one out in the sixth. Lourdes Gurriel Jr. then rolled one to first base, where fill-in Blake Swihart tossed errantly while trying to lead Rodriguez to the bag.
Gurriel dove and Rodriguez tripped over him, clipping his helmet with his left cleat. Both players stayed down momentarily, with E-Rod on his hands and knees and Gurriel sprawled next to the bag.
Rodriguez tentatively took his feet before throwing a series of warmup pitches. At that point, he was removed from the game, favoring what looked like his right leg.
Rodriguez remained on track for his 12th victory, however, leaving with a 1-0 lead after striking out five and allowing four hits in 5 1/3 innings.
