Roy Oswalt allowed three runs while striking out five over seven frames in a rehab start for Double-A Tulsa on Tuesday. He permitted seven hits and didn't walk a batter. Oswalt told the Tulsa World that the performance was "as good as the last outing," when he tossed six innings of one-run ball. The Rockies haven't revealed a specific plan for the veteran righty, but he could need just one more minor league start before joining the big league rotation.
