Arroyo misses start due to back tightness

PEORIA, Ariz. -- D-backs right-hander Bronson Arroyo was scratched from his Tuesday start due to tightness in his back.

The decision was made Monday when Arroyo began experiencing the discomfort.

"I didn't see him," D-backs manager Kirk Gibson said when asked Tuesday morning how Arroyo was doing. "I think he's still pretty jammed up. I don't know what's going on with that. He's not going to do any throwing today I know that."

Arroyo was already a bit behind the other pitchers because he did not sign his free-agent contract until a few days after camp opened.

The 37-year-old is known for his durability, having made at least 32 starts in each of his nine seasons as a full-time starter.

"Not at this point," Gibson said when asked if he was concerned about Arroyo's condition. "We've got a long ways to go. He's never really had a history of missing starts so I feel confident he'll be fine."
