Parker had a pair of rough starts near the end of his season, a sign that something wasn't right with his elbow. He gave up five earned runs in each of those starts, spanning just nine innings. In his other 18 starts, including a six-inning, one-run outing between the two bad ones, he gave up two or fewer earned runs in 17 of them (he allowed three in the other one).
Scouting report: Before having Tommy John surgery in October that will keep him out for the 2010 season, Parker had four pitches he could throw for strikes. He throws two breaking pitches, a plus slider and an outstanding curve. His changeup, which at one time lagged behind, came along nicely before he got hurt, and has the chance to be at least above-average. He can command all of his pitches, has a clean delivery and has shown a tremendous work ethic.
Upside potential: It's obviously going to take him longer to get there because of the TJ surgery, but the expectations are still there for Parker to be a top-of-the-rotation starter.
They said it: "With the track record of this surgery, I'm very optimistic. Most important, knowing the type of player having it helps. Nobody works like him. He will do everything within his power to get back to 100 percent." -- Diamondbacks farm director, Mike Berger
He said it: "The organization is going to work with me rehabbing, and we're going to bust our butts to get back, get healthy and mature a little bit more."
