The first round was also very solid for him (-4).If we are talking about a dream round, it was Tyrrel Hatton's. He scored -8 this Friday at the Canadian Open (the best of the day) to advance 68 places to T2. Corey Conners and Aaron Rai remained among the leaders, although they dropped one place compared to Thursday.The fourth occupant of second place is C.T. Pan, who posted the second-best round to climb 27 places and claim his place among the leaders.The defending champion of the Canadian Open and most renowned golfer in the field, Rory McIlroy, had a much better day than Thursday by scoring -5. With this, he has an overall score of -6 and will start Saturday's round in T12, three strokes behind the leader.A special mention for Michael Block, who was in the Canadian Open thanks to an exemption he received for his outstanding performance in the PGA Championship. Block had a rather poor first round (+7), so although he managed to improve his performance with a -3 on Friday, he failed to make the cut.Canadian Open leaderboardBelow is the complete Canadian Open Leaderboard after the second round.
