The Arizona Diamondbacks have sent starting pitcher Madison Bumgarner back home for further medical evaluation after he cited arm fatigue following his road start on Saturday against the Los Angeles Dodgers, per Reuters (h/t ESPN.com).
Bumgarner gave up five earned runs, four hits and four walks in four innings of a 10-1 loss in his first start of the year.
"My mechanics were fine. It was just one of those days you have during the year, and mine just happened to be the first one," Bumgarner said after the game. "It wasn't like I went out there and threw the ball really well, but I was just one pitch away in the first of it being a completely different game.
