Start up the flake/corner to easy cracks on the slab up and to the left.
Hike underneath and past the slabs leading to the cave/crack on Short Barrel up to a flat, grassy area below the short, clean wall. Climb the large, right-facing flake/corner on the left (west) side of the wall. See the topo.
Sling a big boulder with cordalette or build a gear anchor to TR. It could go clean on gear.
