Things didn't go so well for three former US. Open champions: Angel Cabrera, Graeme McDowell and Jim Furyk. These guys, if you can believe it, are a combined 44 shots over par through two rounds.

They won't be playing the weekend, even though the cut right now is projected at nine over. "I putted poorly, I drove the ball poorly, just things you can't do at a U.S. Open," Furyk, who could have been speaking on behalf of the group, said.

Tiger Woods update: He said after his second-round 70 he injured his left elbow at the Players' Championship: "It is what it is," Woods, using one of his most popular responses, said. Does Tiger still like his chances?

"Yes," he said. "Just keep grinding. You just don't ever know what the winning score will be."

Here are the grisly mid-day course statistics: Merion is playing more than five shots over par at 75.50. The only hole playing under par is the short, 123-yard par-three 13th (2.92). Toughest hole is the 219-yard, par-three ninth (3,69), followed by the par-four 18th (4.62). The course played to a first-round average of 74.21.

Tiger Woods wraps up second round | 1 p.m.

Tiger Woods has left the Merion arena so now all eyes focus on Phil Mickelson, who picked up ground on the field while... sleeping.

Mickelson just started his second round at three-under overall. He and Nicholas Colsaerts (one under) were the only players in the field under par. But for how long?

Mickelson made bogey five on No. 1 and brought every one closer to the top.

Tiger Woods recap: Five years ago he won the U.S. Open at Torrey Pines limping on a left knee so badly his 14th (and last) major victory would be followed by major surgery.

Woods is dragging another left limb at the 113th Open, only this time it's his arm. Woods is clearly suffering some sort of left elbow ailment that puts his chances in jeopardy.

Woods completed his second round Friday with a series of grunts and grimaces as he fought to stay in contention.

The good news is Merion is playing so tough that no Mickelson lead appears safe.

Woods clearly had one of his "grind it out" rounds. He muscled a third shot out of the rough and ended up with a birdie on the 628-yard par five fourth hole. Most amateurs, citing orders from their doctor, would have picked up after hitting into rough that deep.

The birdie got Woods to two-over, only five shots back. He then made a great par save at No. 5 but gave a shot back after chunking a green-side chip at the par-four seventh.

Woods followed his three-over 73 in the first round with an even-par 70.

It wasn't a good first two rounds for the "Supergroup" of Woods, Rory McILroy and Adam Scott. The world's top three players are a combined 13-over par. McILroy is three-over while Scott, this year's Masters winner, is seven-over.

Luke Donald had the lead at one point Friday at four-under before an awful stretch where he bogeyed five of six holes. He fell to plus one overall but made two terrific shots on the par-three ninth to go to the clubhouse at an even-par 140. He followed his opening-round 68 with a two-over 72 and left the course trailing Mickelson by only three.

"I'm very satisfied to be even par," he told NBC right after his round. Donald scoffed at suggestions Merion would be an easy mark this week.

Said Donald: "I didn't quite believe 15-under was going to win this thing."
