Points closed with a 6-under 66 on Sunday, saving par on the last two holes at Redstone Golf Club to outlast Masters-bound Henrik Stenson and Billy Horschel. The final round was halted for nearly three hours because of storms that soaked the golf course.
Points kept alive the streak of Americans winning all 14 events on the PGA Tour this year.
The victory gives Points a spot in the Masters, just like his only other victory did two years ago at Pebble Beach with actor Bill Murray as his partner.
Graham DeLaet of Weyburn, Sask., shot a final-round 72 to finish 10 shots back in a tie for 31st.
