Thanks to readers Ian and Mark for the stories on Jamie Kureluk's jaw-dropping back nine 25--and 12-under on his last 10--in yesterday's opening round of the RBC Insurance Alberta Open.

Twenty-five on the back nine. Is your head spinning yet? Kureluk, a pro at the Cottonwood Golf and Country Club in Calgary, shot 25 to shoot 61. He was two-over-par after four holes and 12-under for his last 10 holes. He was 11-under on the back nine alone. His back nine is by all accounts a competitive record.
