PHOENIX -- For Robbie Ray, the news wasn't the worst it could have been, but it certainly wasn't the best either.
An MRI of Ray's ailing right oblique showed a Grade 2 strain and he was placed on the 10-day disabled list Monday afternoon. No one with the organization wanted to speculate on just how long Ray would be out, but it certainly seems like it will be more than just 10 days.
D-backs starter Zack Greinke missed around six weeks with a similar injury a couple of years ago, and Randall Delgado is still working to come back from an oblique strain he sustained during Spring Training.
"It's not terrible," Ray said of the MRI results, "but it's definitely something that's going to take a little bit of time to come back from. It's one of those things where it's really just how your body reacts to it. The biggest thing is not rushing it, not try to come back before I'm ready."
Ray left his start Sunday in the second inning with pain in the oblique, the first time he had ever experienced an injury to that area in his career.
"Injuries happen in this game and it's time for our guys to step up," D-backs manager Torey Lovullo said. "And we have that mentality every single time somebody goes down -- to get involved, get engaged and pick up the slack. That's what we do here in Arizona."
The D-backs have had plenty of practice with outfielder Steven Souza Jr. and third baseman Jake Lamb missing significant time already and right-hander Taijuan Walker having recently been lost for the season due to Tommy John surgery.
For now, the next man up is Silvino Bracho, who will be in his second stint for the D-backs this year. Bracho, a reliever, will give the team an extra arm in the bullpen for now until a starter is needed to take Ray's place.
Ray's next turn would have been Friday, but it's possible the D-backs could tweak the rotation a bit before then, depending on matchups over the next three days with the Dodgers.
"We have internal candidates that we're walking through right now," Lovullo said. "We're leaving all of our options open."
Reliever T.J. McFarland, who threw 4 2/3 innings in relief of Ray on Sunday, has been stretched out to 77 pitches and is a candidate to start.
Others include Triple-A Reno right-handers Kris Medlen and Braden Shipley. Medlen was scratched from his Monday start, while Shipley was heavily considered before Matt Koch was called up to replace Walker earlier this month.
In other injury news, Souza (right pectoral strain) and Lamb (sprained left AC joint) both threw from 120 feet on Monday. Souza also took five at-bats in an extended spring game, but has yet to play in the field. Lamb has taken ground balls but hasn't thrown across the diamond since suffering some elbow tendinitis.
