Troy Merritt one-upped Masters champion Jordan Spieth at the RBC Heritage.
Merritt, a Spring Lake Park High School graduate, shot a 10-under-par 61 on Friday in Hilton Head Island, S.C., to tie the course record at Harbour Town Golf Links only a few hours after Spieth wowed the gallery with a 62 to match his lowest PGA Tour round.
Merritt tied David Frost's tournament mark set in 1994 and topped the leaderboard at 12-under 130, a stroke off the 36-hole event record.
Merritt, who opened with a 69, saw Spieth's score in the morning and knew the opportunity was there to go low.
"Anytime that you match shot for shot with the Masters champ, with the way he's playing, it's a pretty good feeling," said Merritt, whose career best in four seasons on the PGA Tour is a tie for second last year at the St. Jude Classic.
Merritt had a four-shot lead and was six ahead of Spieth after a day of low, low scoring.
Spieth had the lowest round since Peter Lonard opened the 2005 event with a 62. It was a distinction that lasted just a few hours. Still, Spieth showed the energy and skill missing when he shot 74 Thursday.
