The Arizona Diamondbacks have sent Shelby Miller to the Minor Leagues.
"I've been struggling up here for a while," Miller said. "I'm surprised I stayed up here this long."
Miller has been a major disappointment after the Diamondbacks got him in an offseason trade with the Atlanta Braves for outfielder Ender Inciarte, 2015 No. 1 overall draft pick Dansby Swanson and top pitching prospect Aaron Blair.
"We just have to find a way to get him back to pitching the way he can," manager Chip Hale said.
The right-hander is 2-9 with a 7.14 ERA.
