Tiger & Rory / Getty Images Rory McIlroy and Tiger Woods both missed the cut after the second round at the Abu Dhabi HSBC Golf Championship, played on the Abu Dhabi Golf Course. Rory McIlroy collapsed to a second successive round of 75, to bow out of the event in which finished as runner-up last year. Guess the new clubs are not working yet. He put it down to the speed of the greens and even changed putters for the second round, to no avail; "I just felt the greens I have been practicing on were much faster. It was just a weight issue. I've got four weeks to work on it. I knew it was going to be a tough week. I hit the ball really well in Dubai last week, but it just got worse for some reason. I'm very disappointed, you never want to get off to a poor start, but I've got to realize it's only the start of the season." Tiger Woods thought he had finished safely inside the cut mark on one over, but his bogey five was changed to a triple-bogey seven after discussions with European Tour Senior Referee Andy McFee. Tiger had taken a drop from an embedded ball on the 5th hole after his tee shot had gone way right. Tiger asked Martin Kaymer about the embedded ball and they both agreed that he could get relief, citing rule 25/2 Embedded Ball. Tiger explained; "I called Martin over to verify the ball was embedded. We both agreed, but evidently it was sand. It's tough, I didn't get off to a very good start and I fought hard. I battled back and got it to where I thought I could play the weekend, and thought I might have a chance, just post two low rounds. But I won’t be able to do that.” As no referee was involved at the time, some spectators later asked a referee why Tiger was allowed a free drop, because the ball was in sand. The referee involved and Andy McFee investigated the incident, this is how he explained it; “Tiger hit his tee shot on the fifth way out to the right and when he got over there to the ball, he called Martin Kaymer over and said, ‘look, I've got an embedded ball here’. So Martin came and had look at it, agreed the ball was embedded; Tiger proceeded under the embedded ball rule, dropped the ball and played on. No referee was involved in that situation. It was only later that a couple of spectators walking past the referee who had seen that asked, 'Why did Tiger get a drop there?' and the referee didn't know. Obviously no referee was involved but we suspected it might have been embedded ball. So we went and had a look at the area and thought, well, embedded ball rule just does not apply in that rule. The embedded ball rule is for a closely mown area, only. There's a note to that rule, which all the major tours in the world use, which extends embedded ball relief to through the green, but that is very specific in that it says, in ground other than sand. So wherever you are, you do not get a relief for a ball which is embedded in sand, and that's just a bad lie and you have to play it. Obviously we want people to deal with rules issues themselves, providing they get it right, but unfortunately in this one, they didn't, and it incurred a two-stroke penalty.” Meanwhile Justin Rose is the tournament leader, adding a second round 69 to his opening round of 67 and at -8 under par was one shot ahead of Welshman Jamie Donaldson, Spaniard Gonzalo Fernandez-Castaño and Dane Thorbjorn Olesen. Justin Rose / Getty Images Justin said he had to play a patient game; "I felt like my game definitely sharpened up, when you have perfect distance control you know you are swinging it well. I thought it was a decent enough score to keep the momentum going. I was pin-high probably eight times, but kept leaving myself awkward distances and had to keep patient."
