BRADENTON, Fla. -- As has been the case for the team for much of the spring, the Pirates continue to be plagued by nagging injuries.

Left-hander Phil Dumatrait has had to halt his throwing program again after being bothered by arm soreness while throwing live batting practice earlier this week. General manager Neal Huntington said that though this type of soreness is common in the rehab work that Dumatrait is doing, the soreness is still going to set Dumatrait back a bit in his attempt to pitch in a game this spring.

The Pirates have shut Dumatrait down for the time being, hopeful that the inflammation in his left shoulder will subside with rest. Huntington estimated that it could be about seven to 10 days before Dumatrait gets back on the mound to throw live batting practice again. That timetable is quite fluid, though, as it depends on how long Dumatrait is out and how much the Pirates will have to back him up in his rehab work now.

In other words, when Dumatrait is cleared to return, he'll likely have to play catch for a day or two, progress to throwing side sessions and then move back to the live batting practice session. How much time Dumatrait would have to spend at each of those steps will depend on how long he is shut down in the meantime.

Dumatrait was already expected to start the season on the disabled list and certainly will now. As a result, the Pirates are not overly concerned by this setback since there are no long-term warning signs with the soreness Dumatrait is experiencing.

Additionally, both Andy Phillips and Shelby Ford will also be out for a few days. Phillips is dealing with a stiff lower back, which first tightened up after the Pirates' game in Fort Myers, Fla., on Saturday. Though Phillips reported feeling better on Thursday, he said there is still some stiffness lingering.

Phillips, who is fighting for one of the final bench spots with the club, will not play on Friday and will continue to be evaluated daily to note his improvement. The Pirates want him to be able to compete in a full workout before getting back into a game.

As for Ford, it looks like he will be out through at least the weekend after jamming his right wrist diving for a ball up the middle in Wednesday's game. Ford took some swings on Thursday, but did not take part in the team's full batting practice because of some tenderness in that wrist.

Like Phillips, Ford will continue to be listed as day-to-day.
