But the defending champ wouldn't circle another hole on his back nine.
On Sunday (Monday NZT), it wouldn't budge.
The big-hitting American fired a four-under-par 66 at Missouri's Bellerive Country Club to earn a 16-under total and a two-shot victory from 14-time major victor Tiger Woods (64), with Australian Adam Scott (67) third at 13 under.
