Detroit The highest-ranked player at the Rocket Classic went low on Friday.Cameron Young, No. 3 in the Official World Golf Ranking, came out blazing in the second round and shot a 9-under 61 to tie the course record and vault to the top of the leaderboard halfway through the final playing of the PGA Tour tournament at Detroit Golf Club.Young opened with a first-nine 28, or 7 under, on the strength of six birdies in a row at one point. He even birdied the long, tough, par-4 17th, which yielded only five birdies in Round 1. Already a member of the exclusive 59 Club, he had thoughts of a double dip there until he grinded his way through the second nine, before rolling in a 20-footer for one more birdie at the par-4 eighth hole.Young missed a 17-footer for birdie on his last hole, but it still was a clean, bogey-free card and Young, 29, who already has won twice this season including at The Players Championship, was at 10 under at the halfway point of the tournament. He was one shot ahead of first-round leader Peter Malnati.
