Young struggled with his command and velocity in a 35-pitch outing with the Double-A San Antonio Missions on Sunday, and according to sources, his velocity ran between 81-84 mph, well below normal.
On Monday, Young had an MRI with contrast to enhance the scan. The results were not available as of Tuesday afternoon. The MRI is being sent to noted orthopedic surgeon James Andrews for evaluation.
Young is set to have a traditional MRI on Thursday or Friday as the team attempts to determine what is wrong with his shoulder.
At this point, no one is sure.
"I want answers," Young said. "I had this cleaned up last August. Why am I having trouble now? It's extremely frustrating. All the time and effort and sweat I put back into getting healthy ..."
Young had his 2009 season cut short because of arthroscopic debridement surgery that removed loose fragments in his shoulder in August. Young's rehabilitation program, by his own admission, was smooth and without setback, including his time in Spring Training.
Young tossed six scoreless innings in his first and only start of the season on April 6 at Arizona and complained of soreness in the shoulder the following day. The right-hander was later placed on the 15-day disabled list, retroactive to April 7.
Young was encouraged by how he felt after a simulated bullpen session in Cincinnati on April 23. He threw around 75 pitches and felt good about his command. He was set for a Minor League rehabilitation start the following week, but it was scratched because he felt some soreness in his shoulder.
Finally, last week, Young felt good enough to make a start with Double-A San Antonio. He allowed five earned runs and four walks in two-thirds of an inning. He returned to San Diego on Monday to have an MRI.
"I didn't feel pain during the start, but my stuff wasn't where it should be," said Young, who said the pain he's feeling now isn't in one specific spot and that it moves around.
"Velocity, life, crispness, sharpness on the breaking ball ... it's not what it should be or what it was this spring."
Like Young, Padres manager Bud Black didn't have a lot of answers to offer on Tuesday.
"Chris is sore. It was not normal soreness," Black said. "He's going to rest until he can get a handle on the shoulder. We haven't been able to get a handle on what's going on. Time will give us a better indicator of where we're headed."
