HP Byron Nelson Championship: Hanson leads by one stroke in Texas
Peter Hanson stormed into a one shot lead at the HP Byron Nelson Championship in Texas, despite barely knowing its layout.
The Swedish golfer, still yet to win on the PGA Tour, flew out of the traps and found himself on five under after nine holes; a bogey on the par 14th eventually pegging him back. He then made a six-foot birdie putt on the 18th which saw him card a five under 65 to grab a priceless one shot lead.
Hanson holds that lead over a chasing trio of David Duval, Marc Leishman and Tim Wilkinson.
"It's always nice to get off to a fast start," said Hanson, who withdrew from the Wells Fargo Championship two weeks ago through back injury.
"I gave myself a few chances on the back (nine), made a bogey on 14 from the middle of the fairway and had a reasonable chance to make a birdie on 16.
"It was nice to get off with a birdie at the last. With the greens and how small they are and the run-off areas, if you start missing greens you get some very, very difficult lies and up and downs. Once you start chipping, you will make bogeys."
Elsewhere on the field, defending champion Bae Sang-moon of South Korea endured an up and down sort of round, mixing in five birdies with six bogeys, including a frustrating double at par four eighth, to card a three over 73.
Local boy Jordan Spieth opened his account with a 70, while Players Championship winner Martin Kaymer is two shots further back on three under.
