Tommy Fleetwood is using an Odyssey 2-Ball putter that was released in 2007 - that now costs $13 on eBay - at this week's Genesis Open on the PGA Tour.
Fleetwood chose to replace his Odyssey White Hot Pro #3 with the old school DFX 2-Ball.
The Englishman has added lead tape along the front of the sole. It features a single black line running through the middle of the two balls, creating a secondary alignment aid.
Fleetwood heads into this week's tournament off the back of a tie for 45th at last week's AT&T Pebble Beach Pro-Am.
