Mike Ryan Buys at Tattersalls for Chad Brown

Back for business at Tattersalls for the fourth year in a row, the U.S.-based buying axis of Chad Brown and Mike Ryan were sticking to a tried and tested format with their latest acquisitions from Book 1.

The likes of Digital Age  (Invincible Spirit ), Newspaperofrecord  (Lope de Vega ) and Domestic Spending  (Kingman ) have reached the top flight for Brown's stable, and several of those names were duplicated in around half a dozen that Irish-born Ryan had signed for by lunchtime on Thursday.

"It seems to be polarized, it's either good or it's just okay, but there are a lot of quality horses here and we're trying to be disciplined and sticking to what has worked for us," said Ryan.

"We need horses that can run two turns on the grass, horses that give you a feeling they've got that turn of foot, they can accelerate, rather than just stay one paced. 

"We're delighted with what we've got so far; we've been runner-up a number of times, that's the name of the game.

"I think when you set a bar, it's hard to maintain it, but that's what we strive to do. You can get tempted, but it's a matter of getting the ones you really feel good about."

Ryan had won out for Newsells Park's Kingman filly out of a daughter of the fabled Shastye  at 340,000 guineas (US$484,806), and eclipsed that fee for another colt from the same sire and nursery, the first foal out of Waldgeist 's accomplished sister Waldlied , at 425,000 guineas ($606,007).

He also claimed a 400,000 guineas ($570,360) Dubawi  filly, offered by Watership Down Stud out of Armstrong Aggregates Temple Stakes (G2) winner Priceless , and on Tuesday he had secured another Dubawi, from Croom House Stud out of a half sister to Zoffany , for 340,000 guineas ($484,806).

"We love Dubawi, he fits very well in America," said Ryan. "They're tough, they're sound, they're genuine, they're courageous, they show up. He's a good outcross as well for us, an extraordinary stallion in my lifetime. He's like Into Mischief  —you can't have too many of them."

Expanding on his selection process, which had also included several Lope de Vega fillies, Ryan said: "The first thing that comes is the physical but you want sires that have worked in America, that have quality. At the end of the day if they're stakes horses, by the right sires out of decent female families, there's a global demand when their racing career is over too."

Among Ryan's major American clients have been the likes of Seth Klarman of Klaravich Stables, who also bought a handful of six-figure fillies and colts under his brand by the likes of Kingman and Lope de Vega, and Peter Brant.

Eventually signing for 10 for receipts of 2,300,000 guineas ($3,279,570)—a little down on previous years—Ryan explained that interest from afar remains strong.

"These horses are for multiple owners, but a couple of new owners came in this year," he said.

"The exchange rate is a bit tough now, it's not as favorable as it was 12 months ago, but there is definitely an uptick in interest. People see you can buy proper horses here and bring them back, giving them the right opportunities and giving them to the man who does best on the grass, Chad Brown! New York turf is the best in America and he's the king of New York."
