"He over-raced a bit early and I thought surely he can't keep going," he said. "When I got stuck in, he fought so hard, he's a top-quality horse.
"With the rain we got I started to favour that draw and although we were wide the whole way, we were in the better part of the track. It's great [to equal O'Sullivan] as Lance was a champion jockey and a champion bloke as well. So, it's quite humbling to be up with someone like him."
Trained by Jamie Richards at Matamata, Yourdeel was originally bought as a pin-hooking opportunity by Little Avondale Stud out of Dan Myers' draft at the 2017 National Weanling Sale. Presented at the 2018 National Yearling Sale at Karaka by Little Avondale, he was knocked down to the $100,000 bid of Chris Rutten who shares in his ownership with John Norwood and Rod Preston.
Richards, who also trained 2018 race winner Sword Of Osman in partnership with Stephen Autridge, was quick to point out that the gelding of the horse prior to the Waikato Stud Slipper had played a significant role in his latest success.
"A very sharp knife is the key to this horse," he said. "In the pre-parade ring he was on the toe a little bit so you can imagine what he was like as a colt. A big thank you to the owners and the team at home as they have done a great job.
"He's a very good horse and he will now go to the Sires' in a couple of weeks as long as everything is honky dory at home. He will go down there and be a big chance as if he can ride him with a bit of cover, I think you will really see him explode."
The Group 1 Manawatu Sires Produce Stakes (1400m) is the feature event at Awapuni on March 30.
Just 30 minutes after the Sistema Stakes, Bosson claimed the Group 1 record as his own when Melody Belle won the Bonecrusher New Zealand Stakes.
