A punter who placed a measly $7.80 racing multi earlier this month has missed out on approximately $50,000 by a head.

Mitchell Humphris' tale of woe comfortably slots into the Punters.com.au 'Chamber of horrors', with the Adelaide punter nailing six of seven legs. 

Humphris placed the bet on March 10, focusing on two races at Flemington, three races at Randwick, and a couple of futures markets.

Unfortunately the ambitious punter's dream was crushed immediately, with Nettoyer ($3) going under in the opening event at Randwick. 

The Roche-trained mare sat three-wide without cover for basically the entire 1600m journey but still had the temerity to close strongly for third, beaten 0.3L.

Humphris, who plays cricket on Saturday afternoons, didn't have time to reload on the other six legs following Nettoyer's narrow defeat.

As is generally the way with the scurrilous 'punting gods', his four other selections all saluted that day - Seberate ($3.10) to place in race four at Flemington, Regimen ($2) to place in race nine, Pierata ($2.20) to place in the seventh at Randwick, and Sugar Bella ($4) to win the eighth. 

Humphris had two weeks to wait for the remaining (dead) legs, having taken D'argento to win the Rosehill Guineas at $6, and In Her Time to take out The Galaxy at $8.50.

Of course both horses saluted in comfortable fashion at roughly half the odds secured by Humphris (just to rub further salt into his wounds).

"At least I had In Her Time and D'argento in a few other multis that are still alive," said a silver lining-seeking Humphris.

The original multi would have paid a lazy $65,111 (before deductions) if Nettoyer wasn't caught out in the cheap seats in the ironically-named Aspiration Quality (1600m).
