This is a one-match rivalry, and the record is clean. Gordon Ryan and Lachlan Giles met once, in the Semi-Finals of the 2019 ADCC World Championship, and Ryan won by submission. That was a heavyweight meeting the smaller man took on the way through the absolute bracket, where Giles earned a 3rd Place finish that year.

The styles sit at different ends of the sport. Ryan competes at Super-Heavy and works a top-pressure and back-attack game, with a Rear Naked Choke as his most frequent finish at 19 wins. Giles competes closer to Peso Medio and built his name on lower-body attacks, with the Inside Heel Hook his most common submission at 8 wins. In their one meeting the weight gap and Ryan's finishing edge decided it.

The broader numbers frame the gap. On record Ryan sits at 94 wins against 4 losses for a 93% win rate, finishing 78% of his wins. Giles is at 35 wins and 22 losses for a 61% win rate, finishing 66% of his wins. Against shared opposition the two often landed on the same side of the ledger, which makes the head to head the cleaner measure between them.
