The Welsh ‘Headhunter’ lived up to her nickname by landing four head shots, worth three points apiece to secure Team GB’s 22 gold medal of the Rio Games with a 16-7 victory to make it back-to-back golds.
The Welsh woman had struggled against the taller Spaniard in their earlier encounters but had won their previous two meetings.
And Jones, 23, made an explosive start with two kicks to the head in the space of ten seconds for a 6-0 lead after the first round.
Gomez pegged her back to 7-6 in the second as the nerves were jangling in front of a near-full house at Rio’s Carioca Arena.
But she was able to parade the Welsh flag and the Union flag around in jubilation after two more quick-fire three-point scores early in the third and final round.
Jones had been a surprise medallist as a teenager in London 2012 but was burdened with the expectation of being defending champion here.
Yet the high-kicker from Flint, North Wales, scored three convincing victories to reach the final of the Under-57kilo class – culminating with a convincing 9-4 win over Sweden’s Nikita Glasnovic.
And she ultimately prevailed in convincing fashion against the second-seeded Gomez.
