It was the second run back from a spell for Houtzen, who won the Magic Millions Classic in January and was a game fifth in the Group I ATC Golden Slipper behind She Will Reign.
"She wasn't wound up at her first start back," said Jeff Lloyd.
"The six furlongs today suited her a lot better and she travelled well and sprinted home."
Her trainer Toby Edmonds was well pleased with the run.
"She has a high cruising speed and has had three weeks between runs, so she'll improve a lot from that," he said.
"The Everest is her grand final, so we've left a bit in the tank."

She is the first winner from Reset mare Set to Unleash, whose dam is a half-sister to globe-trotting Champion 3YO Filly Sun Classique.
Houtzen is a star performer for Yarraman Park's flagship sire I Am Invincible, who is fully booked this spring at a fee of $110,000.
Yarraman Park's Hinchinbrook featured in the very next race when flying four year-old mare Super Too blitzed her rivals to win a round of the 55 second Challenge over 955 metres.
The Marc Conners trained mare set the track alight with a blazing front running effort under Blake Shinn to win as she pleased.
"I don't think I've ridden a faster filly," said Blake Shinn.
"She has sustained speed from start to finish."
The second foal of unraced Tale of the Cat (USA) mare Tails Wins, Super Too is a half-sister to brilliant sprinter and promising young sire Super One.
She was bred by Reg Kemister and initially failed to meet her reserve in the ring at the 2015 Inglis Classic Yearling Sale when offered by Broadwater Thoroughbreds.
She was later sold to Marc Conners for $25,000 and has gone on to win five of 11 starts earning over $200,000 in prizemoney.
