A viral golf clip has fans buzzing — literally. Footage from the BMW Championship in Maryland shows pro golfer Tommy Fleetwood, 34, sinking a birdie putt during the final round, but with a twist: some viewers believe a tiny fly helped seal the deal.

The moment, posted by Sky Sports Golf, has racked up more than 3.6 million views on Instagram and another 18,000 upvotes on Reddit, where it was shared under the cheeky title: “A golfer won more than $2 million thanks to a fly.”

In the video, Fleetwood’s ball appears to stop right at the lip of the hole — until, seconds later, it drops in. Some fans joked that a passing insect might have nudged it over the edge.

But was it really the work of a fly? Physicists say no. Instead, they explain that subtle vibrations in the ground, combined with the PGA’s 10-second rule — which gives players up to 10 seconds to see if a ball resting on the edge will fall in — worked in Fleetwood’s favor.

While science may debunk the bug theory, the putt still stands as one of the most dramatic finishes of the tournament, earning Fleetwood millions and sparking one of golf’s funniest viral debates.
