This is kind of old news(this came out yesterday), but I've been AWOL due to personal stuff(nothing bad, just life getting in the way of bloggin) and have pretty much been out of the loop for a few days. Anyways...
Roy Oswalt underwent an MRI on Saturday morning that confirmed the right-hander is still recovering from a left hip abductor strain he suffered on June 30.Oswalt was previously scheduled to throw a bullpen session on Saturday afternoon in hopes that he could reenter Houston's rotation on Tuesday. But following the MRI results, he was placed on the 15-day disabled list retroactive to his one-inning, 17-pitch start on July 11 against the Nationals.

This basically just shows that the Astros mishandled Roy by letting him make the start on July 11th and now will not be able to use Roy if they wanted to until the 26th(I think). It really isn't a big deal and didn't hurt much(I'm not sure Roy will be ready to come back on the 26th anyways), but who knows when he would have been back if they would have just put him on the DL in the 1st place and let him rest the back instead of having him do the bullpen before the 11th and then start the game on the 11th.
