After Doubront suffered his latest rough start on Friday against the Blue Jays, manager Bobby Valentine said the club would at least discuss shutting him down for the season.
Doubront, who allowed Toronto five runs on six hits over four-plus frames, wants no part of that, and while Valentine said no decision had been made, he didn't necessarily sound in favor of it.
"You'd have to consider it, but if he comes into the next season and he gets to this high water mark and then everyone starts to think about shutting him down again, it's probably best if he feels good to let that bar be as high as possible so he can extend it," said Valentine. "As long as he's not going to be injured. You take that from him and the medical room and we'll see."
Doubront felt that declining confidence -- and perhaps some concentration lapses -- had played the biggest role in his recent slide, which has consisted of an 0-4 record and 8.27 ERA in seven starts.
"I think what is affecting me now is my confidence or something like that," Doubront said. "It's not because I'm tired. I feel good, my body feels good."
What's the difference between April and May -- when Doubront was arguably Boston's best starting pitcher -- to now?
"I'd say control," Doubront said. "A couple things, but control is one. Sometimes it's good -- my mechanics are good -- but I need to finish the hitters. That's most important."
