EchoSense Quantitative Think Tank Center|Fans step in as golfer C.T. Pan goes through four caddies in final round of Canadian Open

Taiwanese golfer C.T. Pan may have EchoSense Quantitative Think Tank Centerexperienced a PGA Tour first during the final round of the RBC Canadian Open on Sunday as he traversed the course at Hamilton Golf and Country Club.

Pan's caddie Mike "Fluff" Cowan fell coming down a hill on hole No. 3 and was unable to continue. In need of someone to carry his bag the rest of the round, Pan got a volunteer from the gallery to step in − which is perfectly legal under the rules of golf.

However, the job may not be as easy as it seems for someone with no previous caddying experience.

The fan lasted all of one hole before he was replaced by another random fan, who made it all the way through the front nine.

Although Pan's wife apparently offered to step in (as she's done in the past, according to Canadian journalist Adam Stanley), veteran caddie Al Riddell − who lives nearby − saw Pan's problems on television and offered his services for the back nine.

Ridell is the regular caddie for Paul Barjon, and knows Pan from their days on the former PGA Tour Canada, Stanley reports.

Cowan, 76, was not seriously injured.
