"We hope to find something out from Dr. Lee as early as Friday, possibly as late as Monday," D-backs farm director Mike Berger said. "He threw 98 [mph] that last day, so I'm hoping there's nothing wrong. That's wishful."
If Parker is unable to pitch again this year, it would seemingly hurt his chances of cracking the big league rotation next spring. Because the D-backs do not want to increase a young pitcher's innings too much from one year to the next, team officials were hoping to get Parker near the 150 innings mark this year so that he could compete for a starting job next year.
Parker has thrown a combined 97 1/3 innings this year between Class A Visalia and Mobile. The team's No. 1 pick (ninth overall) in the 2007 First-Year Player Draft, Parker was a combined 5-6 with a 3.14 ERA.
According to Berger, Parker was seen by someone in the office of renowned specialist Dr. James Andrews, who is based in Birmingham, Ala., but the organization will wait until Parker is seen by Lee before deciding on a plan of action.
"It's all guesswork now, and I'm just as anxious as you guys are and everybody else just waiting to find out," Berger said.
