2015 U.S. Open: Live scores, leaderboard updates and more from Friday’s second round

Patrick Reed and Jordan Spieth are just 24 and 21 years old respectively, but they already have one of the best budding rivalries on the PGA Tour. The rivalry could hit a new level this weekend with Spieth and Reed dueling for the U.S. Open title. They share the 36-hole lead and will go head-to-head on Saturday, paired in the final group together.

The two reportedly maintain a friendly relationship off the course and have teamed well in international competitions before -- including a memorable run as Ryder Cup rookies -- but there is no question they are two of the brightest young stars on Tour. Spieth already has one major championship on his resume, while Reed is aiming for his first ever top 10 in a major. Head-to-head battles between the two are also becoming more of the norm. Reed topped Spieth in a playoff at the 2013 Wyndham Championship. Spieth got even earlier this year, outlasting Reed in a playoff at the Valspar Championship in what was arguably the most-exciting finish of the year.

The top 60 players plus ties make the cut at the U.S. Open. The “plus ties” aspect is a major factor as typically more than 60 players make the cut while groups of tied players dangle on the edge of the cut line. On Friday at the U.S. Open, the fate of 15 players hinged on 19-year-old amateur Nick Hardy, one of the final players on the course.

A freshman at the University of Illinois, Hardy played well on Thursday to position himself to make the cut at Chambers Bay and he appeared in good shape to do so easily well into his second round. Then, he started to stumble down the stretch. Playing in one of the final two groups, Hardy entered No. 9 -- his 18th hole -- at 4-over, right on the cut line. At that time there were 60 players at 4-over or better, while 15, including Sergio Garcia, Ian Poulter and Webb Simpson, sat on the outside looking in at 5-over.

Two rounds of the 2015 U.S. Open are in the books and Tiger Woods, Bubba Watson and Rickie Fowler will be among the notable names not sticking around for the weekend. It was no surprise to see Woods and Fowler miss the cut after disastrous opening rounds. Watson ran into major problems on Friday, shooting a 77 to jump to 7-over and miss the cut. The cut settled at 5-over with 75 players making the weekend.

Woods remains unable to find any sort of consistent success. He was far from in top form coming into the event and the issues just snowballed during 36 holes at Chambers Bay. Woods finished at 16-over, the worst 36-hole score in a major championship of his career. He followed n opening round 80 with a 76 on Friday and found himself near the bottom of the leaderboard. Whatever Woods is working on, he still needs plenty more work before he’s ready to contend for another major.

FOX’s first week covering golf has drawn mixed reviews. But one of the better things about their coverage so far have been the open microphones all over the course picking up player and caddie interaction, which we always want more of as golf watchers.

Those mics are also picking up the occasional fan comments and well, they got one individual clearly heckling the hell out of Ian Poulter. The Englishman is certainly one of the more precocious players and often pisses people off on Twitter. But this was an aggressive move by this fan, and Poulter obviously heard it loud and clear.

The second round of the 2015 U.S. Open is beginning to wind down, which means the cut is looming. As things stand right now, the cut line is sitting at 3-over, but could easily jump to 4-over before the round is done. Several big names, including Rory McIlroy and Phil Mickelson, are a little too close to the cut line for comfort.

After a solid opening-round 69, Mickelson has run into a bit of a struggle on Friday. He’s yet to card a birdie in the round and three bogeys have him at 2-over for the tournament. If he manages to stay there, he will make the cut as the number is unlikely to be lower than 3-over. Mickelson still has six holes to play and any slip-ups could put him on the wrong side of the line.

It’s no secret Phil Mickelson has a terrific short game. Golf fans have watched him hit countless shots around the game that seemed impossible -- and may have been for any other player. Yet it can still be mind-boggling to watch him work his short game magic.

After hitting an errant approach, Mickelson was left with a buried lie in deep fescue and a treacherous stance. Of course, he pulled it off with ease.

Jordan Spieth captured the first major championship of his career in April at the Masters and the 21-year-old is right in the thick of contention for his second major at the 2015 U.S. Open. Spieth shot a 3-under round of 67 to move to 5-under for the tournament and a share of the lead. Spieth does have the advantage of being in the clubhouse at 5-under, especially with conditions becoming more difficult throughout the day.

In the early going, it appeared Spieth might really post a low number. He birdied his first hole of the day and tallied three more birdies on his next seven holes to move to 4-under on the round through seven. That run came to a screeching halt on No. 18 when Spieth ran into trouble in a bunker and wound up making a double bogey. He steadied the round on his second nine, carding two birdies and a bogey on the side to finish off the 67. Depending on how the afternoon wave fares, Spieth could find himself in the lead heading to the weekend at a major, a position he’s becoming very familiar with.

Jordan Spieth was cruising along at the top of the U.S. Open leaderboard on Friday, thanks to four birdies in his first eight holes. That’s when the S.S. Grand Slam momentarily ran aground on a sand bar.

More precisely, Spieth’s second shot found a troublesome lie in a bunker, which he proceeded to shank into a side-hill lie in some of that pesky knee-high fescue.

Roughly half the field is yet to even begin their second rounds at the U.S. Open, but the field and the cut line are already beginning to take shape. The top-60 players plus ties will make the weekend at Chambers Bay, which currently projects the cut line to be at 2-over.

It should rise slightly as the day goes on with the course drying out and becoming more difficult in the afternoon. While it might jump to 3-over, beyond that appears unlikely unless conditions really get difficult. That means several notable players are already on the way to an early exit while others will need to play well on Friday to ensure they make the cut.

If Tiger Woods needs any bucking up, as he slogs through another uninspired U.S. Open round at 1-over through 11 holes for the day (11-over for the tournament), he might take some comfort from knowing another past U.S. Open winner is having a far worse day than he is.

Lucas Glover, who prevailed at the 2009 national tournament, was at 11-over 47 in Friday’s second round at Chambers Bay. That’s a 47. After nine holes.

There have been several indignities suffered by Tiger Woods just 24 hours into the U.S. Open. He ended Thursday topping a ball into the turf in one of the more embarrassing sequences in this embarrassing stretch of his career.

Friday did not start much better. Woods missed the fairway again on his first hole, and went off exploring on one of the many fescue hillsides here at Chambers Bay. And Tiger bit it right in front of the cameras -- another insult on the way to a bogey at his first hole.
