"I am going to pitch Friday," Scherzer said Wednesday morning. "Being sick doesn't get you injured. If something could hurt my arm, I would be smart about it. But I didn't work hard all my life to get here and then miss a start because I was sick."
Scherzer said he has been dealing with a sinus infection, low energy, body aches and night sweats. However, he said illness played no role in his last start, when he gave up seven runs over 2 2/3 innings to the Red Sox on Sunday.
Scherzer was scheduled to throw his regular bullpen session Wednesday morning.
Ramon Santiago has had one of the worse cases of illness on the team. What began as a sinus infection in the final week of Spring Training led to strep throat in recent days, knocking him out of the starting lineup Tuesday. He was back in the lineup on Wednesday against the Rays.
Most of the clubhouse has had some sort of symptoms, including manager Jim Leyland.
"Most of it has been the general cold and allergies," head athletic trainer Kevin Rand said.
