The smart 4yr-old held off a late bid from Four Starzzz Flash to make his first winning mark on the open class scene after running a bold second to Christen Me at Addington last week.
Tiger Tara jumped up to 16th after his second in the Maurice Holmes Vase, and the handicappers will have a conundrum to unpick this week as they work out how much further up the rankings Tiger Tara will jump.
His trainer, Geoff Dunn, who owns the son of Bettor's Delight with Bob and Jenny Sandford, said the victory should now give him some flexibility as he plots the path to the second Tuesday in November.
''That should help us in the rankings then we'll assess what we have to do - see how he comes through the run and just go from there, really,'' Dunn said.
Pure Power went to the lead shortly after the start, and the field quickly settled into single file before Anthony Butt went up to sit outside the leader with a lap to go on Pass Them By.
This gave Tiger Tara the ideal spot behind Pass Them By, although driver Gerard O'Reilly still had work to do when Four Starzzz Flash came at him late.
''Gerard did say he's a bit like this - he does it heaps of times - he gets in front then lets them come and goes with them,'' Dunn said.
''You've got to watch the swoopers but he did it pretty nice in the end.''
Tiger Tara is a stallion prospect at the end of his career and can get boisterous before he hits the track. Yesterday was no different as he reared up in the parade ring. But Dunn would much rather see that than a docile Tiger Tara doing the rounds.
''He's a colt and he's a hard case,'' he explained.
''When he's like that is when he's at his best and we were happy with how he was.
''When he's not like that, he's not himself. So that was a really good sign.''
Pure Power finished in third place, but was relegated to fourth after Anthony Butt successfully proved to the Judicial Control Authority that Pass Them By would have beaten home Pure Power if not for Pure Power drifting out in the straight.
The new rule - 869A(2) - was introduced on Thursday and brings the harness code into line with the interpretation of the thoroughbred rule regarding interference.
Pure Power's driver, Samantha Ottley, was fined $450 for allowing her horse to drift out.
