Palm Harbor, FL (SportsNetwork.com) - With scores not going quite as low as they were in the first round, Brendon de Jonge carded a 2-under 69 in Friday's second round and he took a 1-shot lead over five others heading into the weekend at the Valspar Championship.

De Jonge, still looking for his first career victory in his 221st start on the PGA Tour, finished 36 holes at 6-under-par 136. The 34-year-old finished tied for second at the McGladrey Classic early on this season.

"It's tricky out there, you know," said de Jonge. "It's one of those golf courses where it's tough enough to get it in the fairway when it's still and then when the wind blows it obviously added difficulty."

A couple big names sit just one shot back of de Jonge, including world No. 3 Henrik Stenson (70) and Jordan Spieth (67). That duo is joined in a tie for second at 5-under 137 with Ryan Moore (68), Kevin Streelman (69) and Derek Ernst (70).

Lucas Glover (69), Ian Poulter (70), Ricky Barnes (72) and 2008 champion Sean O'Hair (72) are one shot further back at minus-4 on the Copperhead Course at Innisbrook Golf & Spa Resort.

First-round leader Brian Davis struggled on his way to a 5-over 76 and that dropped him into a tie for 27th at 1-under 141. Defending champion John Senden (71) finished at 3-over 145 and he missed the cut.

Beginning the day two shots behind Davis, de Jonge started his round on the back nine, where he did not get off to an ideal start.

Four pars from No. 10 began de Jonge's round before he made a mess of the par-5 14th on his way to a bogey, dropping him back to 1-over for the round.

Following a trio of pars from No. 15, de Jonge made the turn in a big way as he drained a 27-foot birdie putt on No. 18, pulling him back to even par.

De Jonge made it back-to-back birdies as he poured in a 16-foot birdie putt on No. 1, getting him into red numbers for the first time. De Jonge went on cruise control for a while when he made four straight pars from No. 2

De Jonge traded a bogey on six for a birdie on seven and he later closed out his second round with a 6-foot birdie conversion on No. 9.

Spieth tied for the best round of the day, which is why he was able to jump into a tie for second. He had a great start to his round with birdies on one, three and six before tripping to a bogey on seven.

It was an up-and-down back nine for Spieth as he made four birdies and two bogeys. A birdie at the last completed Spieth's 67.

Stenson, making his first appearance at this event, holed a 20-foot eagle putt at the par-5 first, but he gave those two shots back with bogeys on two and nine. Stenson then made eight straight pars from No. 10 before draining a birdie at the last.

"It was a bit of a weird day or a bit of a slow day for me," said Stenson. "I got off to a great start ... A lot of fighting, grinding for pars. It was blowing pretty hard there and you have to hit some good shots to hit some greens."

Moore converted four birdies and just one bogey in his round, while Streelman also had four gains to go along with two bogeys.

Ernst, playing in the later pairings, held the lead throughout most of the day before a tough finish. He did not get off to a great start, however, as he made two bogeys on 12 and 13 to go along with a birdie on 11.

Ernst surpassed de Jonge, who had the clubhouse lead as a member of the early groups, with five straight birdies from No. 17. Now at 8-under and two shots ahead of de Jonge, Ernst began his move down the leaderboard with a bogey on four.

Still in the lead at minus-7, Ernst closed with bogeys on seven and eight along with pars on five, six and nine.
