But even if he had not done that, his demeanor has spoken volumes.
Davis on Friday revealed that he found out last week that he has thyroid cancer, and the veteran insisted on pitching that night against the Rockies and plans on making his first two regular-season starts, April 3 and 8, before undergoing surgery April 10.
"It was shocking," catcher Chris Snyder said. "But to see the way he carries himself and the way he's going about it, he's not down by any means; he's the same guy. So I think the best thing for everyone in here to do is be the same guy we've always been with him."
Davis said he's gone through his preparation for Thursday's start just like the 33 he made in 2007.
"It's tough news to hear," shortstop Stephen Drew said. "But Dougie has a positive attitude and it's pretty much cureable, according to the doctors, and that's a good thing. He's a good clubhouse role model for us."
It's not known how much time Davis will miss. Team physician Dr. Michael Lee said it could be four to six weeks following surgery, but only time will tell.
Davis was a valuable contributor to the rotation last year, his first in Arizona, when he went 13-12 and, maybe even more importantly, ate up 192 2/3 innings.
"He's going to fight through it and we're going to have his back, and hopefully we get him back as soon as possible," Snyder said.
