By Rory Carroll AUGUSTA, Georgia (Officialsportsbetting.com) – Justin Rose said a couple of key mistakes kept him from having a run at the lead in Friday’s second round at the U.S. Masters and expected calm weather and faster greens to play to his strengths this weekend. The 36-year-old Olympic gold medallist from England was lurking just three strokes behind the tournament leaders after shooting an even-par 72 in gusting winds for a one-under-par 143 total heading into Saturday’s third round. “We have actually been quite lucky with the weather, with all the storms of Monday and Wednesday to have the course playing somewhat firm and fast is going to be a lot of fun.” Rose, one of the best ball strikers in the game, balanced four bogeys with four birdies, gaining strokes on both of the par-fives on the back nine.
