MASTERS races are supposed to be for veteran greyhounds whose best form could be behind them but Jabeni ignored that script by posting the fastest time of the night at Wentworth Park on Saturday.
The Blake Moroney-trained bitch, who turned four in July, disputed the early lead with kennelmate Ice Reina before leading at the first turn and coming away to score by five lengths in 29.76.
That was .04sec inside the best of Jabeni's previous 26 performances, which comprised seven wins and 11 placings.
But Jabeni's early duel with Ice Reina gave trainer Moroney plenty of cause for concern because at her previous start, at Wentworth Park on November 12, Jabeni had jumped quickly from box three but was badly hampered trying to reach the rail and was knocked out of the race before finishing fourth.
After Saturday's race Moroney said: "When her kennelmate Ice Reina pushed up inside Jabeni approaching the first turn I thought to myself oh no, here we go again.
"But fortunately Jabeni was able to cross Ice Reina without too much trouble to lead clearly going through the catching pen.''
Cooper's Hawk, who has contested all but one of his 21 racetrack appearances at Wentworth Park, made full use of his knowledge of the course to win on Saturday night in 30.07, his personal best figures at headquarters.
Flying Tiny Tim, a brilliant beginner but extremely wide runner, had box three and made the early pace while Cooper's Hawk, who drew box six, was second early but secured a perfect rails run when the pacemaker veered off the track.
Cooper's Hawk's trainer Michael Galea said: "I was really worried going into the race because I thought that if my dog was outside Flying Tiny Tim on the first turn he would get pushed off the track and lose all chance.
"I was hoping Cooper's Hawk would come out of the boxes behind Flying Tiny Tim and get across to the rails and luckily that's how it worked out.''
Sacred Silence, named after a line in a song called Toxicity by Armenian/American heavy metal group System Of A Down, scored a game first up Wentworth Park win in 30.34, upsetting odds on favourite Our Boy Duke.
Sacred Silence led early but was headed by the hotpot leaving the back straight before coming again to win by a half head.
"I name a lot of my dogs after song titles or lines from songs and would have liked to call this dog Toxicity but didn't think that would be acceptable so I selected one of the lines from that song,'' trainer Chris Carl said.
"I bred Sacred Silence from my bitch Serena Serena, who won a couple of races at Wenty Park but had more ability than she showed on the racetrack as she was not a keen chaser.''
Wyndra All Class scored her fourth successive Wentworth Park win on Saturday night but while her time of 29.84 was outside her quickest Wenty figures of 29.67 it was arguably her bravest performance.
The Daniel Gatt-trained bitch collided at the start but regained her balance almost instantly to set off after the pacemaker Princess Audrey, and took the lead on the back straight.
The inexperienced Rockstar Rampe almost cost himself the race when he collided with pacemaker Hold It at the top of the straight in Saturday night's Maiden Final but finished determinedly to win by just under a length in 30.34.
After the race Kayla-Jane COLEMAN, whose husband Shaun Evans trains the winner, said: "I thought he had thrown the race away when he ran into the back of Hold It because young dogs sometimes lose a lot of ground when something like that happens.
"But he handled it well, got going again, and finished strongly to win.''
