The marvelous golf of German Marcel Siem kept him at the top of the leaderboard at the Trophée Hassan II competition in Morocco on the European Tour. Marcel Siem / GettyImages Marcel needs a win here at the Trophée Hassan II, to stand any chance of climbing into the Official World Golf Ranking’s top 50 and earn himself a debut Masters Tournament appearance next month. His second round of -4 under par 68 keeps him on top of the leaderboard, and maintains a comfortable three shot lead over the field. Marcel admitted that his round could have been better, but he still has the Masters appearance in his sights and actually hopes the wind does get up a little bit because he enjoys the challenge; " I think it should have been better than it was to be honest, the bogeys on four and seven were a bit weird because I was in the middle of the fairway there. But otherwise, this course is always tricky and I should accept the 68 because it’s always nice to go under par after such a low round the day before because that can be quite difficult to follow up on sometimes. I actually hope the wind blows a little bit more because I actually enjoy the challenge of playing into the wind and it would also keep the guys behind me away from me because if there is no wind out there then people can go very low around this course." David Horsey remains in second place at -9 under par, tied alongside Mikko Ilonen. David had a -5 under par 67, while Mikko took a big leap up the leaderboard with his round of -6 under par 66. Alone in third spot is Spaniard Pablo Larrazabal after his sudden surge up the leaderboard with his wonderful -8 under par 64 around the Golf du Palais Royal course.
