Steve Wheatcroft hates going to Monday qualifiers. He was reminded Friday why they can be worth it.Wheatcroft, who narrowly qualified for the Houston Open at the start of the week, ran off three straight birdies early in his round and kept bogeys off his card for a second straight 5-under 67. That gave him a one-shot lead over D.A. Points and Jason Kokrak going into the weekend at Redstone Golf Club.Rory McIlroy also will be around for two more days, but just barely.In only his 10th full round of the year, McIlroy walked onto the seventh green — his 16th hole of the day — and saw that he was tied for 77th. He two-putted from 85 feet on the fringe for birdie on his next hole, and then safely found the green at the par-3 ninth for a 70. By the end of the day, McIlroy made the cut on the number.“It a weekend where I can have a couple more rounds and try and get confidence in what I'm doing,” McIlroy.His big surprise came later. McIlroy, feeling as though he needs more rounds to get ready for the Masters, decided to enter the Texas Open in San Antonio next week.Phil Mickelson also made the cut on the number after a bogey on the last hole for a 71. Mickelson, who has played the Masters with two drivers in the bag, decided to play Redstone on Friday with two 3-woods in the bag, though one of them is so strong it acts like a driver.“If I can play like I did the back nine, I'm going to give myself a lot of birdie chances,” Mickelson said.Wheatcroft can't bank on anything.Not only does he have no status on the PGA Tour, he has only conditional status in the minor leagues. After missing out on a Web.com Tour event last week in Louisiana, he figured he might as well enter the Houston Open qualifier Monday.“Monday qualifiers are terrible. They're just not fun, plain and simple,” Wheatcroft said. “I was on the PGA Tour in `07, played terribly. I had no status. So I had to be back to Monday qualifiers and pre-qualifiers the next year. I hate them.”Wheatcroft had some good sessions with swing coach Matt Killen, felt his game was getting better in the last month, and figured it was all about timing. He made it by one shot into the field, and he's playing well against a strong field at Redstone.He was at 10-under 134, the first time he has ever been atop the leaderboard on the PGA Tour. The tournament is only halfway over, and Wheatcroft has been around long enough to not look too far ahead. Even so, this has Cinderella ramifications.Wheatcroft can become the first Monday qualifier to win on the PGA Tour since Arjun Atwal at the Wyndham Championship in August 2010. A win would put him into the Masters for the first time, and perhaps more importantly, give him a two-year exemption.Points had a 71 with 17 pars and one birdie. He didn't make anything on the greens, which he attributed to his putting stroke and firm, afternoon greens instead of the old putter he once borrowed from his mother.Kokrak at a 69 and will play in the final group with Wheatcroft, whom he knows well.Stewart Cink, winless since the British Open in 2009, showed more signs of getting his game on track. Cink contended in the Humana Challenge on late Sunday afternoon, and feels as if he's getting closer. He had a 66 and was tied for fourth with Brian Davis (70). Two-time major champion Angel Cabrera, the Argentine who has a home at Redstone, had a 72 and was four shots behind, along with Bill Haas (70) and Cameron Tringale (73).Also lurking was Dustin Johnson, who threw away careless shots but was still only five shots out of the lead.‘Dufnering‘ all the rageJason Dufner is all the rage on the PGA Tour without even playing this week in the Houston Open.Dufner was at a school Irving to help promote one of the charities of the Byron Nelson Championship. After sitting on the floor for a few hours, his back was sore and he leaned against the wall. That's when a photo was taken of the two-time tour winner.Dufner is shown slouched against the wall, with a vacant look on his face as the teacher speaks to the children. Dufner is known for showing little emotion, even with a major championship on the line. But the photo went viral on Twitter, and it wasn't long before Rory McIlroy, Luke Donald and others struck similar poses.It's now called “dufnering.”Briefly• European Tour: Marcel Siem of Germany shot a 4-under 68 Friday to move to maintain his three-shot lead after the second round of the Hassan II Trophy tournament in Agadir, Morocco. The French Open champion made seven birdies mixed with three bogeys on the Golf du Palais Royal course to move to a 12-under total of 132. Mikko Ilonen (66) of Finland and 2011 winner David Horsey (67) of Britain were tied for second.• McIlroy stays in Texas: Rory McIlroy is going to play another week in Texas to get ready for the Masters. McIlroy decided Friday to play next week in the Texas Open, wanting one more tournament to try to find his form ahead of the first major of the year. The two-time major champion has only played five tournaments this year, making just two cuts.He has completed only 10 rounds through Friday of the Houston Open.McIlroy lost his No. 1 ranking last week to Tiger Woods, who won at Bay Hill. Even so, it gives the Texas Open its biggest name in more than a decade.It's a big change from last year, when McIlroy took off three weeks before the Masters.
