Gout Gout stunned in Stawell Gift semi-final by South Australian school teacher John Evans

The much anticipated showdown between teenage sprinter Gout Gout and Lachlan Kennedy at the Stawell Gift will not take place after both athletes missed out on the final.

John Evans, a South Australian school teacher, stunned Gout in the sixth and final semi, resulting in the 17-year-old not qualifying for the Stawell Gift final.

Evans won the semi from a 9.75m in a scorching time of 12.10 - the fastest of the semis.

The schoolboy put in a huge effort to almost claim victory, but ran out of time.

Gout's rival Lachlan Kennedy was also unable to overcome his backmark and has missed out on the final after being beaten by Dash Muir.

The other semi-final winners were Jasper Thomas, Mitchell O'Neill, Patrick Martin and Joshua Lotsu.

Scratch-marker and Paris Olympics 100m semi-finalist Bree Rizzo charged into the women's Gift final after winning her semi in 13.81.

Only the winners of the six semi-finals on Easter Monday advance to the final later in the day at Central Park, where the eventual victor of the 120m handicap race will pocket $40,000.

Despite the shock loss, Gout was all class with his fans following the sprint - making sure he high-fived as many as possible.

The teen will pocket $50,000 from his appearance, so he has plenty to smile about.

'It's been a pretty stressful couple of days,' Evans told Channel 7.

'My girlfriend will tell you it's been all nerves, but that's what the Stawell Gift is about.

'But a fantastic opportunity. Someone like myself will never get the chance to race against the likes of Gout Gout and Lachlan Kennedy, all these top stars.

'You look at the footage, I look across and I can see him like 'gee whiz'. He had me scared for a second. I could hear all the crowd hyping up, the commentators.'
