Jon Rahm turned the final round of the Hero World Challenge into a victory procession, surging to a four-stroke win in the Bahamas on Sunday.
Englishman Justin Rose, requiring a top-three finish to return to world number one, is in a three-way share of eighth, five strokes back, after a 68.
Rahm and Stenson were at 10-under 134.

Sweden's Alex Noren went even closer at the 181-yard par-three, holing his nine-iron tee shot.
The ball pitched a foot short of the flag and it trickled into the cup, completing a remarkable run of eagle, triple bogey, ace in three holes for the world number 18, who is level with Rose at eight under.
