Good description and photo
Although I have little experience with White-rumped Sandpiper, I believe that the bird's white rump that's visible in flight is distinctive for the species. The flanks of this bird seem almost unstreaked, but perhaps that's a feature that can vary quite a bit. The reddish base to the bill was also convincing.
