Despite having won just about every feature race on the Tasmanian calendar the Burnie Cup had eluded him.
He won the race in 2002 with Barringtonboutique but she was later disqualified.
But with his sonin the sulky, Devendra made amends despite sitting outside of the leader Grand Passion for almost the entire journey.
Grand Passion looked under pressure in the back stretch the last time while Rattray sat quietly aboard Devendra just waiting for the turn into the home straight where he called on his charge for the big effort.
Devendra (Doctors Delight-Queen Carey) was well backed to start the $3.70 second favourite behind Mister Sumna that galloped at the start and threw away any chance when he galloped midrace.
Those that backed Devendra were queuing up to collect long before the gelding hit the line three metres clear of High Flying Ruler with Willie Winalot flashing home to edge out race leader Grand Passion in the last stride.
Devendra is raced by the Rattray Family trust in partnership with long time stable client and family friend Viv Clark.
"I am glad to have won this race for the first time and to win it with Viv (Clark) is something special,"said.
"This horse has promised plenty but up until now hasn't delivered a lot, although he has been placed behind some good horses," he said.
Despite Devendra's lack of winning form leading up to this latest assignment Rattray believes he might still be good enough to warrant a trip to Sydney to spend some time in his son's stables at Menangle.
The Burnie Cup win gave the Rattrays the feature race double for the weekend having won the Harry Holgate Memorial with Divas Delight last Friday night in Launceston.
Rattray said he was delighted to win a race named in honour of the former Premier and Racing Minister who he believes did a lot to support the racing industry when he was in office.
