Oosthuizen, Todd face off on Sunday

Louis Oosthuizen joined Brendon Todd at the top of the leaderboard after a scintillating 64 at the HP Byron Nelson Championship.

However, it was a very slow start for the South African, who carded two bogeys in his first four holes but brought it back with three birdies in a row over the next three holes.

Oosthuizen would hole five more birdies on the back nine, including a birdie on the par four 18th, to card a six under 64 to grab the lead on ten under for the tournament.

“I made a nice birdie on 5, and just really made some good putts,” said the former Open winner, who withdrew from last year’s Byron Nelson championship with a neck injury.

“Every opportunity I had for birdie I actually made. My eye was good today, and I hit a lot of them really close.”

Meanwhile, Todd’s scorecard was dominated by 12 consecutive pars, with the only blemish being the bogey on the par five fourth. A couple birdies and a good putt on the 18th saw him step up to share the lead.

“I wanted to get one more birdie under my belt so I could be that much closer to shooting the score I need to win Sunday,” said Todd.

Just one shot back of the leading duo are American’s James Hahn and Gary Woodland, alongside Canada’s lefty Mike Weir.

Meanwhile, Morgan Hoffman was shaping up to hold a share of the lead before he found the bunker on the 18th and ended up dropping two shots to leave him on eight under overall, along with Ireland’s Padraig Harrington .
