The 38-year-old grinder shot a two-over 74 Saturday to remain in the lead at the Nationwide Tour's Livermore Valley Wine Country Championship. At 4-under 212 overall, he is the only player below par after 56 holes.
'It was a crazy day,' Uresti said, and he was right.
Only nine of the remaining 61 players broke par Saturday at Wente Vineyards, pushing the average score so far this week to 75.112. The course ranked No. 1 in difficulty on last year's Nationwide Tour schedule.
'I've never played in a U.S. Open, but I can imagine it is just like this,' said Gary Christian, who had a 72. 'You just try and do whatever you can to shoot whatever you can.'
Uresti opened his round with a double-bogey at No. 1, then posted a bogey five holes later to drop to 3 under. He rebounded with a birdie at No. 10 and finished with eight consecutive pars -- a small miracle in the third round.
'To start off with a double and then stay right there -- I feel pretty good about that,' Uresti said. 'Today was a patient day. You just go out there and keep grinding.'
Uresti hit 9-of-14 fairways and 12 greens in regulation.
'Today has really been the only windy day,' he said. 'The ability to keep it low is an advantage out here.'
On Sunday, Uresti will be playing for his first win since the 1994 Shreveport Open -- which still ranks as his only career title. But it won't be a cakewalk.
There are five players tied for second place at even-par 216, including one who has already won this season: Skip Kendall (Chitimacha Louisiana Open).
'When you have greens like your garage floor, it gets pretty tough,' said Kendall, who shot a 72. 'It is tough and playing really difficult -- a 72 is a pretty good score.'
Jason Day and Arjun Atwal shared the round of the day, 4-under 68, and were tied for second place with Kendall, Christian and Mario Tiziani (70).
