Rodriguez, McDonald deal with injury setbacks

PITTSBURGH -- The uglier underside of the dark-horse pitching depth that has carried the Pirates to the top of the Major League standings -- the injuries that have put that depth into play -- got a bit drearier on two fronts Saturday.

Wandy Rodriguez and James McDonald are both dealing with setbacks that are certain to shelve them for a long time. A.J. Burnett, another sidelined member of the season-opening rotation, is making good progress from the torn left-calf muscle that landed him on the DL two weeks ago.

Rodriguez, who experienced tightness in his left forearm while doing some flat-ground throwing on Friday, has been shut down and has an appointment with the team's medical staff. It is the same condition that forced him out of a June 5 start in Atlanta and onto the DL.

McDonald will see Dr. Keith Meister in Dallas on Tuesday for confirmation of diagnosis of the source of his shoulder discomfort by team doctors. McDonald declined to disclose that diagnosis, characterizing it as premature.

If Dr. Meister's findings differ, McDonald plans to seek a third opinion from Dr. James Andrews. Otherwise, he will turn his attention to curing the condition that has ailed him all year.

"I'm eager to find out just what's going on," said McDonald, who conceded that he hasn't felt right, even while he was part of the Pirates' regular rotation through April. "At the beginning, there really was no pain, it just felt different. Then when it started to hurt, I thought, 'There's something wrong. We've got to look at this.'"

McDonald was on a conservative throwing program until starting a Minor League rehab assignment on May 27.

"After not throwing for a while, my first couple times out, I felt fine," McDonald said. "Then the same pattern started over again, where I couldn't get loose and had the discomfort."

McDonald made the last of his six rehab starts on June 22.

On the positive side, Burnett had a problem-free 38-pitch bullpen session on Friday. On Tuesday, he will throw a simulated game spiced with elements of his biggest challenge, the ability to charge off the mound to field the position.
