But prior to Sunday's game, Leyland added that Sanchez "just didn't look right" in his start and was admittedly concerned.
"The funny part about it is, there's no pain or anything," Leyland said. "That's the information I'm getting. … I'm concerned about it. You don't have to be a rocket scientist to smell something. It just didn't look right coming out [of his hand]."
Sanchez did say after the game that despite feeling fine physically, his pitches didn't have their usual power and velocity.
"I can't explain it, I would like to know how this happened," Sanchez said.
