The 40-1 shock held off the challenge of the favourite Shea Shea (3-1) and second favourite Sole Power (4-1) to win the race by half-a-length.
It was a big result for jockey Steve Drowne who is fighting his way back after he took a year out of the sport when he was wrongly diagnosed with epilepsy.
"It’s funny how it happens. When I was off for a long time with a broken leg I came back and Queen’s Logic turned up. Now Jwala's turned up," he said.
"You just need to land on one like this and you're back up there. I’ve not been through a lot – it’s just been frustrating. I was misdiagnosed; it took five months to get a second opinion and five months fighting with the DVLA to get my driving licence back and you cannot ride if your driving licence has been revoked on medical grounds.
"I should have been out a fortnight and in this game if you miss a month you miss 30 per cent of your rides. If you miss a year you miss 100 per cent of them and have to start again. Every jockey will tell you it's hard enough to get rides at the moment, without being off."
Trainer Robert Cowell said that he did not consider his horse an outsider despite his 40-1 odds.
"It wasn’t really a huge surprise, I’ve been telling people for two days that she had the best chance of my three because she’s so uncomplicated and has a very high cruising speed, which is what you need," he said.
