Irving, Texas — Jordan Spieth wasn't sure what par was at his hometown AT&T Byron Nelson and thinks it actually might have helped him through some frustrating early holes.
There's a reason the Masters champion was uncertain — overnight rain turned one of the signature par 4s at the saturated TPC Four Seasons into a pitch-and-putt par 3 at 105 yards for the second round Friday.
Spieth had a birdie 2 along with most players within three shots of second-round leaders Steven Bowditch, Jon Curran and Texan Jimmy Walker. Gary Woodland had a hole-in-one when it was still possible that the easy wedge over a pond would play as a par 4, before tour officials made the switch.
"I was able to fire at more pins, not really worry about anybody else," said Spieth, who shot 64 — 5 under because par became 69 to put him at 6 under for the tournament. "Really actually helped because I didn't know what score I was at when it's a par 4, 4 par, par 3, don't really know what it's at."
Walker, who won the Texas Open not far from home in San Antonio in March, finished with a par at 18 just before play was halted by darkness. He had a 66 to reach 9 under.
There were 33 players on the course after the start was delayed three hours.
"I got little kids," said Walker, a five-time winner who is second to Spieth in FedEx Cup points. "We didn't want to have to get up earlier again and go do that."
Bowditch, the first-round leader, shot 68 with seven birdies and six bogeys. Curran matched the day's low round at 63. All three were at 130 with the two-round par total at 139 instead of 140. Cameron Percy was a shot back after an eagle at the par-5 seventh for a 64.
Defending champion Brendon Todd shot 68 and was 1 over for the tournament with the projected cut at 1-under 138.
The fairway at the normally 406-yard 14th was deemed unplayable in the landing area after 5 inches of rain fell starting about midnight, pushing the total to about 17 inches in less than three weeks at the Four Seasons course. Texas officials have declared May the wettest month in the state's history.
Muddy footprints marked the area where a dip in the fairway funneled down to a rain-swollen canal off to the right. Standing water covered the ground under some trees, about the same spot where Spieth chipped out in Thursday's first round and ended up with a bogey.
The temporary tee box was on the fairway side of a pond that wraps around the left side of the green. Tour officials believe it was the first such alteration since the 2005 WGC-Match Play Championship, when flooding at La Costa in Carlsbad, California, temporarily turned a 467-yard par 4 into a 162-yard par 3.
"It was really tricky," said the 21-year-old Spieth, who birdied his final three holes at Nos. 7-9. "We get up there and it's 105 yards, but it's off a steep upslope and really muddy. I don't think we'll see that, if ever, again, something like that."
Curran, a 28-year-old rookie looking for his first PGA Tour win, shot 29 starting on the back nine, with the same boost as others on the 300-yard head start at 14. He had bogeys on the first and sixth holes to prevent a serious run at a 59 — with an asterisk of course.
Percy, a fellow Australian with Bowditch, played the 14th while going 5 under through his first 10 holes. He shared fourth with Dallas resident Ryan Palmer (66).
"I quite enjoy it. I love that tee shot," said Percy, who turned 41 this month and has never won on the PGA Tour. "Happy to get out there and drop it at 105 yards. I got up and down, so that was nice."
Nick Watney had a bogey-free 65 and was in a group at 7 under that included 48-year-old Jerry Kelly, who also shot 29 while starting on the back nine. Yes, he had a 2 on 14.
"I would have counted those as 1-under par 4," said Kelly, who had the last of his three tour wins in 2009. "That's all I got to say."
There's another strong chance of overnight storms into Saturday, but the forecast improves considerably later in the day and into Sunday. Workers spent about six hours getting the course ready starting around 4 a.m. Friday and might have to do it again.
"They've probably not really enjoyed each night for the last month or two months," said Spieth, who finished 16th in his first pro tournament as a 16-year-old amateur at the Nelson five years ago. "But hats off to them and hopefully they can catch a break now."
And the players can know what par is.
