The world No6 led the playoffs heading into the tournament and, providing he maintains his form over the final two rounds, Stenson will receive a US$10 million prize to go along with his winner's cheque.
Meanwhile, fellow Kiwis Steve Alker and Tim Wilkinson are firmly in the hunt to retain their PGA Tour cards for the 2015-16 season. With Lee the only New Zealander to finish in the top 125 on the money list - currently sitting in 20th spot - Alker and Wilkinson were unable to automatically claim their cards.
Alker had four top-30 finishes to manage 185th on the money list with earnings of US$236,862, while Wilkinson finished nine spots further back after making only eight cuts all season to earn US$171,654.
But both Kiwis have a chance to retain their playing status on the major tour through the second-tier Web.com tour finals, a four-tournament series that rewards the top 25 earners with PGA Tour cards.
And Alker and Wilkinson are right in the mix during the third tournament of the four, the Nationwide Children's Hospital Championship. The Kiwis are 11th and 14th respectively at the halfway mark in Ohio, sitting right on the cusp of the top 25 overall.
