Kevin Na and Jason Kokrak rallied to win the QBE Shootout after birdieing 12 of their last 13 holes.

Na and Kokrak faced a three-shot deficit, but the American duo fought back in Naples, Florida, where they dazzled in Sunday's fourballs.

A combined 12-under-par 60 saw Na and Kokrak prevail by a stroke ahead of Billy Horschel and Sam Burns (61) at the unofficial PGA Tour team event.

Na and Kokrak, who also reeled off nine consecutive birdies, ended the week 33 under as overnight leaders Marc Leishman and Jason Day (65) finished third alongside defending champions Matt Kuchar and Harris English (62).

"We got off to a poor start," Na said. "We kept telling ourselves there are plenty of birdie holes out there. I started making some birdies and we got hot."
