Tom Walsh has won the highly anticipated head-to-head battle with Jacko Gill and smashed his own New Zealand Resident record to win the shot put title at the Athletics National Championships in Dunedin.
Walsh fired a massive 21.11m throw with his third attempt to claim a seventh successive national title.
Little separated the pair before Walsh's third throw - Gill actually held the lead at that point with a throw of 20.22m.
The Aucklander extended his best throw to 20.23m but had no answer to Walsh's mammoth effort.
Both athletes will contest the Indoor World Championships in a fortnight.
Walsh flies out to Melbourne to compete in the IAAF World Challenge event on Saturday, before heading to Portland Oregon for the World Indoor Championships, while Gill will bypass Melbourne and head straight to the indoor champs in the USA.

Auckland teammate Rochelle Coster, after five minor medals in 2010 - 2014 and disqualification last year, finally won gold in the Braken Learning women's 100m in a personal best of 11.64. Previous champions Kelsey Berryman (2015) and Fiona Morrison (2014) filled the minor placings.
The much awaited under 20 women's 100m was taken out by Zoe Hobbs from Lucy Sheat in 11.93 while Hamish Gill beat Jacob Matson and Jordan Bolland in the under 20 men's race. Gill also won the under 20 men's long jump gold with 7.36.

Javelin thrower Tanya Murray set a new national under 17 record of 45.53 winning the Athletics Taieri under 18 contest.
