Thames swung at a 2-2 pitch from Scott Proctor and the ball ricocheted off the bat directly into his face. The impact sliced open the outfielder's eyelid but vision tests came back normal. Thames is currently listed as day to day.
"That's kind of a scary moment," Blue Jays manager John Farrell said. "At first, you thought it hit him in the helmet, to take the helmet off, but it was a direct blow to the eye and then caromed to the visor and took it off.
"But I think, right now, he's fortunate that the laceration is the only thing that is sustained."
Thames wanted to remain in the game but Farrell and the club's medical staff noticed the area around the eye was starting to become swollen. He was taken out of the game to undergo further examinations and rule out a possible concussion.
The 24-year-old rookie spoke to reporters after Toronto's 3-0 victory with a noticeable cut that started on his eyelid and extended just below his left eyebrow. The injury did not require stitches, and Thames thinks he'll be fine moving forward.
"I think it looks worse than it actually is," Thames said. "Tomorrow we'll see if it's swelling and what not, but it should be OK.
"I got away with it. I'm lucky."
Thames is batting .259 with 10 homers and 33 RBIs in 85 games this season.
