Canada's Brooke Henderson moves into a tie for 5th at CPKC Women's Open

Even Brooke Henderson, the winningest professional golfer in Canadian history, can still learn on the job.

Henderson, from Smiths Falls, Ont., climbed 33 spots up the leaderboard on Friday at the CPKC Women's Open, shooting a 5-under 66 to sit in a tie for fifth at 5 under after two rounds.
