In a wild finish just as the Academy Awards was getting started, Hahn saved par on the 18th in regulation for a 2-under 69 that got him into a playoff with Dustin Johnson (69) and Paul Casey (68).
Casey was eliminated on the second extra hole — No. 10 — when Hahn and Johnson hit dangerous flop shots over the back bunker and converted birdie putts.
On the par-3 14th, Hahn made his birdie and then kept his head down as Johnson missed a 12-footer.
