Eclipse Award-winning trainer Chad Brown is leaving nothing to chance in Saturday’s $500,000 Diana Stakes (G1), sending out four of the seven older fillies and mares entered in the 1 1/8-mile race over the inner turf.
Brown will be going for his record-extending 11th win in the Diana, having won nine of the last 10, including the last four. His first victory came in 2011 with Zagora, and since 2016, his horses have won every edition save in 2021, when British trainer Charlie Appleby went 1-2 with Althiqa and Summer Romance.
Along with Zagora, Brown’s winners were Dacita [2016], followed by Lady Eli [2017], Sistercharlie [2018-19], and Rushing Fall [2020] - with those last three going on to take the Eclipse Award as Champion Turf Female - and In Italian [2022], Whitebeam [2023-24] and Excellent Truth [2025] picking up the streak.
Representing the Brown barn this year will be multiple graded stakes winners Dynamic Pricing and Portfolio Duration from Klaravich Stable, Juddmonte’s multiple Grade 1 winner Segesta, and Kathynmarissa, owned by Michael Caruso and Michael Dubb.
The quartet has been first, second, or third in 35 of 47 career starts with nine graded stakes wins (four of them G1) and combined earnings in excess of $4.7 million. Dynamic Pricing, a 5-year-old Irish-bred, is the only one to have previously run in the Diana, finishing third in last year’s edition.
“The Diana is one of the most prestigious, most important Grade 1 races in this division for older female turf horses in the country - if not the most important race,” said Brown, whose eight individual Diana winners were 15-5-3 in 25 starts of the Spa’s turf. “It's at that middle distance of a mile and an eighth where you'll have milers move up and mile and a quarter horses cut back. It's a really fair distance to put the best horses out there to run against each other.
“It's a race I've long targeted with my best group of turf fillies each year,” added Brown. “You develop a feel over time of which horses will like the course and the distance and the timing, and then you work backward from this race and really play for it. Plenty of times we've been lucky enough to hit the mark with the ones that could step up and do it.”
Portfolio Duration is the most lightly raced of the fearsome foursome, but could be the most talented. The 4-year-old filly is 3-2-0 from five starts and has rocketed from a maiden victory on Dec. 3 at Tampa Bay Downs to a 4 ¾-length allowance score to a game second-place finish in the Distaff Turf Mile (G2) at Churchill Downs and, most recently, a front-running score in the 1 3/16-mile New York on June 5 at the Spa.
“I think the cutback will work in her favor,” Brown said. “She doesn't need the lead; she can run off the pace. She's a pretty versatile horse. I'm happy to see her develop this year into the horse we thought she could be.”
Her fellow Klaravich color-bearer, Dynamic Pricing, took last year’s Just a Game (G1) on yielding turf. She returned to win the Perfect Sting at Saratoga but has yet to reach the winner’s circle this year, finishing a close-up fourth in the Jenny Wiley (G1) and a narrowly beaten second in the Beaugay (G3).
“She loves Saratoga,” Brown said. “She was very effective in the Just a Game over yielding turf.”
Kathynmarissa, who made her first 10 starts for trainer Rick Dutrow, Jr., came off a five-month layoff to win an optional-claimer last August for Brown. This year, she scored a rallying 1 ¼-length victory in the Modesty (G3) at Churchill Downs, and most recently, was outfinished by stablemate Portfolio Duration when third in the New York in her August debut for Brown. She followed in May with a rallying win over then stablemate Gezora – last year’s Grade 1 Breeders’ Cup Filly and Mare Turf (G1) winner -- after missing the break in the 9-furlong Grade 3 Modesty at Churchill.
“She was meant to be more forward in both of her races,” Brown said. “She missed the break at Churchill and still won. Last time, I was surprised by that. Maybe she lost a little of her speed this season, I'm not sure...but she's training well, and this distance will be fine for her.”
Juddmonte’s homebred Segesta had a successful 2025, with two victories and two seconds from six starts, including the Matriarch (G1) and the Matchmaker. She made it back-to-back Grade 1s with a three-quarter-length win in the Apple Blossom at Oaklawn, and most recently was third in the Just a Game over a firm turf at Saratoga.
“She's in good form and has two races under her belt this year,” Brown said. “A mile and an eighth is definitely within her scope.”
Adding an international flair to the field is Cathedral, a graded stakes-placed daughter of Too Darn Hot who was fourth at 90-1 in last year’s Breeders’ Cup Filly & Mare Turf at Del Mar. She enters off a seventh in a field of 15 going a straight mile in the Duke of Cambridge (G2) on June 17 at Ascot.
“The filly ran well in the Breeders' Cup Filly and Mare Turf last year, and she ran a good race at Newmarket over a mile and one eighth over fast ground at the Guineas meeting to finish second in a Group 2,” trainer Kevin Philippart de Foy said. “She was beaten less than two lengths in a Group 1 in Ireland in her first run for us, and we knew the filly would appreciate added ground at the Breeders’ Cup.
“The filly travels well, and this seems like a good starting point for her in America. We'll see where she goes next,” he continued. “The filly came out of the Ascot race in good shape, and we're looking forward to it.”
Cheyenne Stables’ Ozara is 3-for-3 at the Spa, winning a division of the De La Rose and the Ballston Spa (G2) for trainer Miguel Clement, as well as breaking her maiden in 2023 when in the care of Miguel’s late father, Christophe Clement.
The Irish-bred mare is 8-2-2 from 17 starts and has black type victories in the 2023 Wait a While, the 2024 Ginger Brew, and the 2025 Monroe, all at Gulfstream Park.
Rounding out the field is the New York-bred Five G, a Grade 2 winner on dirt who is 1-1-1 from three turf starts, most recently having finished third in the Mount Vernon on June 3 at the Spa.
