Merrill Kelly, the club’s reliable front-line starter, was placed on the 15-day IL with a teres major strain in his right shoulder.
Manager Torey Lovullo said that Kelly will not need surgery and said that the "concern (level) is yet to be determined." Still, it did not sound as if the Diamondbacks have been encouraged by the news on Kelly thus far.
“We’re not looking in terms of weeks as what we had hoped for," Lovullo said. "So I think the next step up is a month, more than that.”
When asked whether Kelly will be back by the All-Star break in mid-July, Lovullo responded, "I don't know. Hard to say."
