Sean O’Hair posted his first win on the PGA Tour in three years Sunday by tapping in for a bogey to edge Kris Blanks in a playoff at the $5.2 million Canadian Open. It was the fourth PGA Tour victory for O’Hair, who started the fourth round three shots off the lead. The win takes some of the sting off what has been a frustrating season for O’Hair who missed 10 of 17 cuts coming into the Canadian Open. “It has been a humbling year,” said O’Hair, who sacked two of his swing coaches this season. “I don’t know what to say. It has been a tough road.” O’Hair, who turned 29 earlier this month, shot a final round two-under 68 to get into his first career playoff with fellow American Blanks as they both finished at four-under 276.
