By Fred Albers, PGATOUR.COM Correspondent Thirty Minutes: Tiger Woods had a bad half hour. He had a four-foot birdie putt on the 11th hole to take sole possession of the lead and missed. Woods then made double bogey at the 12th. In thirty minutes he went from a chance to take the lead to outside the top 20. Woods was in danger of losing the round but made an eight-foot par putt on the 13th hole that changed his demeanor. He then birdied two of his last four holes to finish at 5 under. Throughout the round, Woods did a very good job of controlling the trajectory of his golf shots on a windy day. Water ball: Rory McIlroy is in need of a new sleeve of golf balls. He put five balls into the water on the back nine at Muirfield Village in the first and second rounds. McIlroy had three water balls on Thursday then another two on Friday. To his credit, McIlroy rallied to shoot 71 on Thursday but could not recover on Friday as he posted a 79 and missed the cut by three. Waterfall: The streams at Muirfield Village tumble down into gentle waterfalls throughout the golf course creating a “babbling brook” effect and a very pastoral setting. That wasn’t the case on Friday. Following a downpour, those little streams and waterfalls looked and sounded like Niagara Falls. The golf course took on a tremendous amount of water in a short period of time but remained playable. The greens retained their speed although the fairways were soft. Golf balls that were running out into the rough on Thursday, hit and barely left their own divot following the rain delay. Tough finish: The last three holes on the golf course took their toll. Players staggered to a finish with the par-3 16th hole playing to a stroke average of 3.257. The 17th hole was slightly less dangerous at 4.227. They were the second and third most difficult holes on the course. The 18th, with a back left hole location, played the sixth hardest on Friday but was still scoring a difficult 4.164. That’s a tough threesome to finish off a round. The tenth hole was the most difficult giving up just eight birdies and playing to an average score of 4.328.
