The Masters: Report Card\nHow the top-10 players on the World Ranking entering the Masters fared\nWhat worked: Tiger hit 50 greens in regulation, sticking plenty of approaches, but he didn't make birdies.\n\n What didn't: Notably, his putter, but he also hit too many drives into the pine needles.\n\n U.S. Open prospects: Solid. Woods has won the Buick at Torrey Pines six times, including four in a row.\nWhat worked:There was little to take from a week that began with him hiring a new teacher, Butch Harmon.\n\n What didn't: Only Søren Hansen and amateur Drew Weaver hit fewer fairways in two rounds than Els (16).\n\n U.S. Open prospects: Who knows, but like Mickelson, after he signed with Harmon, will Els win the Players?\nWhat worked:He was pleased with his ball-striking (29 greens hit in rounds one and two) and his chipping.\n\n What didn't:Like Woods, his putting. "I think I've been neglecting it a little bit," Mickelson said.\n\n U.S. Open prospects: It's a home game for Lefty, who has won the Buick three times, but not since 2001.\nWhat worked: Believe it or not, he was on the leader board early, with two birdies in his first four holes.\n\n What didn't: Like Els, Stricker didn't hit fairways, but this normally solid putter needed 60 in two days.\n\n U.S. Open prospects: Usually, he'd be a favorite, but you worry about his accuracy and putting woes.\nWhat worked: He had a solid round from start to finish with a tournament-best 54 pars.\n\n What didn't: He couldn't get his approaches close to the pin and was hard-pressed to make any long putts.\n\n U.S. Open prospects: Torrey hasn't suited him. Ogilvy has three missed cuts and a 67th in four starts.\nWhat worked: He hit 16 greens during Thursday's 70, making many par-saves after tough two putts.\n\n What didn't: Hit just eight greens Sunday, his lowest total of the week, and made seven bogeys.\n\n U.S. Open prospects: The '03 champ has never liked Torrey, making only one Buick cut (2008).\nWhat worked: Choi hit 12 fairways and 13 greens Thursday during a week-best 72.\n\n What didn't:Played the par-5s in one over par, never the way to go about winning a green jacket.\n\n U.S. Open prospects: With a spotty record at Torrey Pines (four MCs, no top-10s), he won't be a favorite.\nWhat worked:Middle rounds of 71-70 represent his only consecutive subpar rounds at Augusta.\n\n What didn't: Is there too much pressure to win a Masters for Australia? Opening rounds in '07, '08: 74, 75.\n\n U.S. Open prospects: There isn't much history. He has never played the Buick and has no top-20s at the Open.\nWhat worked: He led after round one for the third time thanks to hitting 15 greens in regulation.\n\n What didn't: Rose needs to avoid the distractions that come with the lead. He shot 78 on day two.\n\n U.S. Open prospects: A solid Open player with two top-10s in three tries, he has no prior success at Torrey.\nWhat worked: Singh's three rounds at par or better were his best at a major since the 2005 PGA.\n\n What didn't: Couldn't convert putts from less than 10 feet, by his count making just one of seven Friday.\n\n U.S. Open prospects: He has no top-10s in six tries at Torrey Pines but has seven in 14 U.S. Opens.
