AUGUSTA, Ga. -- A day after international players hogged the top of the leaderboard, Americans Fred Couples and Jason Dufner share the second-round lead in the 76th Masters, each completing 36 holes at 5-under-par.
Couples started the day even and shot 67, the low score of the second round. Dufner followed his opening 69 with a 70.
Lee Westwood held the lead at 6-under until he bogeyed the 18th hole. Dufner also bogeyed the 18th.
Phil Mickelson had 68, which has him just three shots off the pace and he tries to win his fourth Masters in a nine-year span. Tiger Woods is going in the opposite direction. Woods, who had a first-round 72, is 2-over through 14 holes. While not in danger of missing the cut (5-over and better seems safe) he'll be well off the lead, with a whole bunch of players ahead of him.
Keegan Bradley has had an interesting day, with five bogeys and three birdies on his front nine. He's 4-over with two holes left, and 3-over for the tournament.
3 p.m.: Lee Westwood continues to hold the lead in the 76th Masters, but 52-year-old Fred Couples is turning the clock back and making a huge push, just a shot off the pace.
Couples is 5-under for his round and just birdied No. 16, his second straight and seventh of the day. He's 20 years removed from his only victory in the Masters, but he's played well here the past two years: sixth in 2010, tie for 15th last year.
Westwood is playing the 18th, and has had a very steady round. He opened with 10 pars, bogeyed No. 11, birdied 12, and birdied 15. He's at 6-under, looking to win his first major.
Jason Dufner and Sergio Garcia are tied with Couples at 5-under. Dufner briefly took the lead from Westwood when a birdie on the 16th got him to 6-under, but he bogeyed No. 18 to fall a shot back. Garcia, like Couples, is 5-under on his round, and is playing the 16th hole.
Keegan Bradley has played four holes and has yet to make a par: bogey-birdie-birdie-bogey. He's 1-under for the tournament. Tiger Woods opened with birdies on Nos. 1 and 3, but just bogeyed the fourth. He's also 1-under for the day and the tournament.
Noon: Lee Westwood has been a par-making machine so far in the second round, making seven straight to remain in the Masters lead. He's been joined at 5-under by Peter Hanson, who has yet to make a par through four holes: double bogey-birdie-birdie-birdie.
Rory McIlroy is making a move. He closed with two straight birdies in his first round, and has opened with two birdies in his first four holes today to push to 3-under, two shots behind the leaders.
Ben Crane (10 holes) and Jason Dufner (eight) both started the day at 3-under, and are both 1-under for the round, tied for third.
Phil Mickelson has made two early birdies; because he opened with 74, he'll need a few more to work his way onto the first page oif the leaderboard.
10 a.m.: The weather for the second round is much different, with cooler temperatures, stronger wind, and another chance for rain.
Roughly one-third of the field is on the golf course, and there's been some movement on the leaderboard. Louis Oosthuizen, who shot a first-round 68 to trail leader Lee Westwood by one, double bogeyed the par-5 second hole, and after a birdie on No. 3, has bogeys on Nos. 4-5 to fall back to 1-under. Westwood has just started his round, making a par on No. 1.
Ben Crane is 1-under for his round through three holes and is a shot behind Westwood at 4-under. Jason Dufner has also reached 4-under after a birdie on No. 2.
Phil Mickelson (2-over) has a 10:46 a.m. tee time, while Tiger Woods (even-par) is in the second-last group of the day, off at 1:42 p.m. Keegan Bradley (71) also has an afternoon tee time, at 1:31.
