"Well, I just gave up a double, so I was a little bitter, so I probably chomped my gum a little harder than normal," Chafin said.
So hard, in fact, that he snapped a crown off one of his teeth.
"It was a tooth I had root canal on and fillings and then we put a crown on top of it, so once you grind it all the way down and put a crown on it, there ain't much," Chafin said. "It's like a little stir stick straw thing holding my tooth together."
Chafin didn't tell anyone about the tooth until later.
"I took it and casually put it in my back pocket," he said of the crown. "I proceeded to walk the next two guys because I was not very focused, but I was able to get the last guy out and even when [pitching coach Mike Butcher] came out for a visit, he didn't notice. I went back in the dugout and smiled and everybody said, 'What happened?'"
Chafin went to the dentist the next day and got the tooth fixed.
The 27-year-old gave up smokeless tobacco this year and replaced it with the gum. It was suggested to him that maybe he should stop chewing it so hard in the future, but he had a better idea.
"Stop giving up doubles," he said.
No decision yet on Ray
The D-backs have not announced what the next step will be for left-hander Robbie Ray, who is on the disabled list after being struck in the head with a line drive during the last road trip.
Ray threw a simulated game Saturday and came through it without any problem. D-backs manager Torey Lovullo said the team is discussing whether Ray will need an additional rehab start and when he might rejoin the rotation.
