Having earlier registered his seventh training victory in the GII Wonder Again Stakes courtesy of Fitz Right (Charlatan), Klaravich Stables' lightly raced PORTFOLIO DURATION (GB) (f, 4, Night of Thunder {Ire}–Shemya {Fr}, by Dansili {GB}) took command from the opening bell of Friday's GI New York Stakes and never relinquished the lead, just holding off French raider Cankoura (Fr) (Persian King {Ire}) to give Brown his sixth win in the 9 1/2-furlong contest.It was a second graded winner on the card for Klaravich and Brown, who won the GII Bed O' Roses Stakes with 'TDN Rising Star' Ways and Means (Practical Joke) and a third for Flavien Prat, who was also aboard Fitz Right.Facing the starter for just the fifth time in her career, Portfolio Duration was well backed at odds of 4-1 and was put straight into play by Prat, as several of her rivals in behind were pulling and otherwise tugging for rein in a very messy run passing the stands for the first time.The 4-year-old got the opening couple of furlongs in :24.39 and was still nicely within herself through a half in :49.21. Kathynmarissa (American Pharoah), who defeated former Brown stablemate Gezora (Fr) (Almanzor {Fr}) in last month's GIII Modesty Stakes, had first crack at the pacesetter and drew right alongside, but having expended a minimum of energy for the opening six panels, Portfolio Duration swatted away that bid with relative ease. Cankoura, rank for the better part of the opening three-quarters of a mile while riding the rails beneath Clement Lecoeuvre, emerged as a rail three off the inside and looked every bit a winner. But Portfolio Duration was kept to her task by Prat and was saved by the wire.Gezora, last year's GI Breeders' Cup Filly & Mare Turf winner, but recently transferred to the barn of Bill Mott, was also headstrong, traveled three wide the trip and gave way readily from three furlongs out.Sales history: 185,000gns Wlg '22 TATDEF; 150,000gns Ylg '23 TATOCT.
