Rain pushed back the start of the second round of the AT&T Byron Nelson Championship, but once players got on the course they made plenty of birdies. Here's how things stand after the second day at TPC Four Seasons Resort, where three players share the lead:
What it means: Heavy rains delayed the start of the round by three hours, and in a rare decision tournament officials reduced the course to a par 69. Bowditch began the day with sole possession of the lead, but he was first caught by Curran and then by Walker, who won earlier this year in the Lone Star State at the Valero Texas Open.
Round of the day: Curran lost in a playoff earlier this year in Puerto Rico, and he is again in contention after a 6-under 63 in the second round. The rookie opened with five birdies across his first seven holes and made eight during his round, taking a share of the 36-hole lead as he looks to win for the first time.
Best of the rest: Jonathan Randolph matched Curran's total of 63, moving from the cut line to within two shots of the lead. The Mississippi native made seven birdies and only one bogey, including four birdies en route to a 30 on the back nine.
Biggest disappointment: Keegan Bradley won here in 2011 and set the course record in 2013, and after an opening 66 he appeared ready to contend once again. But Bradley followed with a 1-over 70 to drop six shots off the pace, carding only two birdies against a bogey and a double bogey on No. 6.
Main storyline heading into Saturday: Once the second round is complete, the player to watch is Walker, who already has two wins this season but still seeks his first top-20 finish in this event after nine prior starts. Another contender is Jordan Spieth, who moved into contention with a 5-under 64 after runner-up finishes at each of the first three Texas events this season.
Shot of the day: The par-4 14th hole was reduced to a 104-yard par 3 because of overnight rains, and Gary Woodland made the most of the change. Woodland holed his wedge for his first career ace, a shot that helped him to a 6-under 63 in the second round.
Quote of the day: "I just need to go out tomorrow and shoot a round like I did today, really zero in on the targets and see if I can get some mid-range putts to go." - Spieth
