BOSTON -- Red Sox center fielder Mookie Betts crashed face-first into the low barrier that defines Fenway Park's center-field triangle while running full speed and exited Friday night's 13-10 loss to the Toronto Blue Jays after two innings.
The team later announced that Betts had sprained his lower back on the play. Manager John Farrell said after the game that X-rays were negative and Betts had some scratches on his face below his bottom lip.
"Obviously the impact of the wall, and also when he landed there was a little bit of a twisting effect where he's got a sprain in the back," Farrell said.
Betts was injured while pursuing Justin Smoak's deep drive that carried almost to the 420-foot sign in center. His face struck the metal screening above the padded wall, and he fell to the ground. Right fielder Rusney Castillo eventually retrieved the ball, and Smoak wound up with a triple.
Farrell said Betts did not exhibit concussion symptoms.
"All those tests were done at the ballpark," Farrell said. "He took quite an impact obviously. The facial abrasions are very minor."
Betts remained in the game for one more out to conclude the top of the second and came out to the on-deck circle at the end of the second, but when the Red Sox came out in the third, Castillo had moved to center field and Alejandro De Aza had replaced Betts in the lineup, playing right field.
"[His back] was tightening up with each stride he was taking," Farrell said.
Betts hit a solo home run in the first inning against the Jays. The Red Sox squandered an 8-1 lead, allowing the Jays a nine-run seventh inning.
