Peter Hanson and Sueng-Yul Noh were tied for third at 65. Martin matched his career best Sunday with a third-place tie in the RBC Heritage at Hilton Head, S.C. He also finished third last month in the Puerto Rico Open.
Martin opened with a 10-foot birdie putt, the first of six birdies on the front nine, most set up by approach shots within 10 feet. One exception was his 26-foot birdie putt on No. 5. He opened the back nine with a 14-foot birdie putt, made a 10-footer on 11 and a 20-footer on 13.
Svoboda birdied six of his last nine holes.
Like Martin, the 34-year-old Svoboda has never won on the PGA Tour and appreciates how much can change in the next three rounds. At the same time, New Orleans has seen its share of maiden tour triumphs. It has happened in six of the past nine years, and 10 of the past 16.
"I'll take that stat," Svoboda said.
Svoboda's best career finish on the PGA Tour is a tie for 15th at the Shriners Hospitals for Children Open in Las Vegas last October.
Hanson's round was highlighted by an eagle on the par 4 sixth hole. After a 277-yard drive to the middle of the fairway, Hanson knocked in his second shot with a 6-iron from 183 yards.
Hanson noted that he used the same club for a hole-in-one during a practice round at Lake Nona in Orlando, Fla., last weekend.
"So it's holed out twice in the last five days," Hanson said.
Hanson, who missed the cut at the Masters, said the key to his strong start in New Orleans was probably putting away his clubs for four days after returning from Augusta and trying to relax more.
"We want to do this so exact and be so precise," Hanson said. "I over-read putts and overanalyze the shots, trying to figure this game out. I think sometimes you have to let the score come to you instead of you going after it."
Daly City, Calif. • Karine Icher of France birdied four of her first seven holes and finished with a 6-under 66 at Lake Merced to take the lead in the inaugural Swinging Skirts LPGA Classic.
The start was delayed two hours because of fog and play was suspended because of darkness with 24 players unable to finish the first round.
The gallery sang "Happy Birthday" to Lydia Ko on her 17th birthday as she started from the first tee, and Ko delivered with a 68 that left her tied for second.
