After opening in 75, Na shot 67-64-64 to reach 14 under. He was two strokes off the lead when he finished play but finished three back of winner Jimmy Walker.
“I shot 4 over the first day and it wasn’t looking too good to make the cut,” Na said. “Played awesome the second day and survived the cut. … And, you know, I just tore it up on the weekend. Just absolutely tore it up.”
Na said he spent two and a half months in Korea rehabbing his back – “acupuncture, chiropractic, physical therapy, and rehab all in one spot.” He then eased his way back into competition.
Na will play next week’s Shriners Hospitals Open in Las Vegas, where he lives and won in 2011.
