Sit start a bit left of the tree on a good flake/jug. Head straight up with a long move to a an obvious vertical pocket, and continue up on pockets and side pulls, trending a bit right when nearing the top. Finish with a slightly dicey top out.
This is on the first boulder above the parking, the same as Stir the Pie. From the trail head, take one of two trails up the hill to the right to the first boulder. Wretch is in the middle of the long face, vertical face that faces the trail head, around the corner to the right of Stir the Pie. It starts just left of the tree.
2 or 3 pads. The route migrates a bit. A spotter would be nice as the top out is a little dicey.
