On Tuesday, Aidan O'Brien refused to be drawn on whether Sun Goddess is the best two-year-old filly that he's ever trained, standing resolute in the face of Matt Chapman's persistent line of questioning, with “she looks like she probably could be” ending up as the best that the Sky Sports Racing presenter was able to get out of the master of Ballydoyle.On Friday, however, after watching the daughter of Sioux Nation win her seventh race of an exacting campaign, surely there can no longer be any doubt, even for the man blessed to have trained outstanding two-year-old talents such as Lake Victoria (three Group/Grade 1 wins), Rumplestiltskin (two), Misty For Me (two), Minding (two), Happily (two) and Precise (two).The bare facts show that, with this fourth top-level victory in the GI Breeders' Cup Juvenile Fillies Turf, simple in its execution but no less impressive than everything that came before it, Sun Goddess now exists on a different plane to her predecessors at Ballydoyle, at least those of her own sex.Whether it's six furlongs or an extended mile, the straight track at the Curragh or the two turns of Keeneland, it all seems to come alike, with her list of vanquished rivals including more than one filly who could reasonably be considered a champion in any ordinary year.Look no further than Libertango (No Nay Never), for example, the winner of the GI Breeders' Cup Juvenile Turf Sprint which kicked off Friday's card, but no match for Sun Goddess in last month's Cheveley Park Stakes at Newmarket. Or perhaps Green Empress (Saxon Warrior), a Group 1 winner at the beginning of the month in ParisLongchamp's Prix Marcel Boussac, before chasing home Sun Goddess for the third time this season in the Juvenile Fillies Turf.Most concerningly for those tasked with trying to lower her colours in 2027, O'Brien believes that the best could be still to come.“She's probably going to change a lot through the winter,” said the trainer. “She's big and she's rangy. She's a super mover and she has a great mind. You'd say there's no doubt looking at her that she's going to be more of a three-year-old than a two-year-old. She is unusual and her movement is very unusual. If you see her, the way she walks and trots and canters, she's a physical specimen that is very different.”In victory, Sun Goddess made O'Brien the winningmost trainer in the history of the Breeders' Cup with 22 winners, an outright record he lost and then regained over the course of the next 90 minutes or so, with Bob Baffert having drawn level with the success of Hughes (Into Mischief) in the GI Breeders' Cup Juvenile, before O'Brien went clear again courtesy of his GI Breeders' Cup Juvenile Turf hero Haffner (Justify).The first of his 23 winners at this meeting was, of course, Johannesburg, the winner of the Juvenile back in 2001, with whom comparisons will now obviously be drawn after Sun Goddess emulated his achievement of winning four top-level races as a juvenile.“Johannesburg was an incredible two-year-old,” O'Brien continued. “He was our first Breeders' Cup winner and he did what she did, winning four Group 1s as a two-year-old. We haven't had anything else to do that before, especially a filly with the scope of hers. He was a smaller, compact sort and he looked like a two-year-old – she looks more like a three-year-old than a two-year-old. She'll be trained for the Classics and I'm imagine that the English Guineas will be where she'll start.”Sun Goddess has been ridden in all but one of her nine starts by Ryan Moore who, remarkably given the calibre of the field that chased his filly home, didn't feel that we saw the best of the general 6-4 favourite for next year's 1,000 Guineas.“What she's done this year is very unique,” Moore said of his 17th Breeders' Cup winner. “That is her fourth Group 1 from nine starts. That was her first over a mile, though, and the first time round a bend.“I'll be honest, I don't think you saw the best of her today. The ground was a little bit more dead than I was expecting it to be and the pace was very slow, and she ended up in front a long way out, doing nothing. She's not usually in front that early, so she was still a bit idle there. It's hard to know where the bottom is for her. Hopefully, she can continue next year.”Green Empress and Johnny Murtagh's Curracloe (Baaeed) completed a one-two-three for the Irish raiders in the Juvenile Fillies Turf, while Joseph O'Brien again had to settle for the runner-up spot behind a horse trained by his father when Folsom Blues (Blue Point) passed the post less than two lengths behind Haffner in the concluding Juvenile Turf.“We hate beating Joseph or any of the lads, we really do,” said a gracious Aidan in the aftermath of that record-breaking triumph. “But it's a business, it's sport and we don't give them an inch. They are not lucky enough to have the quality of horse that we have. Our stock is so much better and, while I'd always prefer it if they beat us, we don't ever let them beat us in any way.”He added of Haffner, “Our horses weren't right the one day he didn't run well [when finishing seventh in the G1 National Stakes at the Curragh]. They had a low-grade infection. He won the [G3] Acomb at York, the [G2] Royal Lodge at Newmarket and we were a little bit worried about the easy mile here, but Ryan had him in a great position.“He's by Justify, so that makes him very exciting for us. The lads have covered all the good mares by him, so it's very exciting. Ryan thinks he could get a mile and a quarter next year – or even more – so he's a proper Classic contender.”Moore benefited from a late switch to take the mount aboard Haffner after his original mount, Great Barrier Reef (No Nay Never), was withdrawn earlier in the day, while the jockey merry-go-round involving Juvenile Turf Sprint winner Libertango proved even more dramatic, with her regular rider, Billy Loughnane, displacing Flavien Prat at the eleventh hour.“I've ridden this filly in every single race, and in every piece of work she's ever done, and I thought I was going to have to give up the ride on her today,” said Britain's new champion jockey, explaining the circumstances behind the late change of plan which saw him ride at a career-low weight of 8st 5lb.“It was awful thinking someone else was going to ride her, but big thanks to George [Boughey, trainer] and all of the team. It was literally 45 minutes before the race that it was confirmed.“I've watched my weight for the last two weeks. I managed to just get enough off in the sauna and I'm sat on the smallest saddle I've ever ridden on. It's good to be able to get the weight off. I'm riding at 8st 10lb later on, so I'd been aiming for that and I'd never been down to 8st 5lb all the time I've been riding.”It was the first of what promises to be many Breeders' Cup successes for Loughnane, likewise for trainer George Boughey, with both men ending the season as it began following their Classic breakthrough with Bow Echo in May's 2,000 Guineas.“Billy had ridden her all year and he text me when he got to the track saying he weighed in a lot lighter than he expected,” Boughey added. “I'd like to apologise to Flavien because he'd been booked a while and it was probably one of his better mounts of the day. But she's been ridden so beautifully by Billy all year. To say he wasn't riding her until 55 minutes before the race, he's just an extraordinary talent.”He added of the satisfaction derived from this victory with Libertango, one of only two horses to have beaten Sun Goddess this year when winning the G3 Albany Stakes at Royal Ascot, “The Breeders' Cup for me is as good as it gets. It was the plan to come here even from Royal Ascot and it wasn't a huge surprise that she was able to put in a performance like that today.”Libertango was chased home by Adrian Keatley's Hell Of A Spin (Naval Crown), who “ran a blinder” in the words of his trainer to hit the frame in Group company for the fourth start in a row. His previous efforts included a third-place finish in the G2 Gimcrack Stakes at York's Ebor Festival, a meeting which, if Friday's evidence is anything to go by, should be the first place to look when it comes to doing form study ahead of Saturday's card.Back in August, Libertango (Lowther Stakes), Sun Goddess (Harry's Half Million) and Haffner (Acomb Stakes) were all winners on the Knavesmire, with their respective victories over two months later at Keeneland ensuring that William Derby, chief executive and clerk of the course at York, could be found smiling as broadly in the winner's circle as any of their connections.Bacio and Notable Speech will be among those trying to complete a similar double on Saturday, with the former representing perhaps the home team's best chance of preventing a clean sweep of the turf races at this year's Breeders' Cup for the Europeans.If the raiders are to pull it to off, then Aidan O'Brien will no doubt have to play a leading role again on Saturday, when victory for just one of his five runners on the card would see him draw level with his own record of 28 Group/Grade 1 winners in a calendar year, with no horse having contributed more to that tally so far than Sun Goddess.The best two-year-old filly O'Brien has ever trained? Surely, she has to be now.The post Sun Goddess Completes Group 1 Four-Timer on Breeders’ Cup Friday for Record-Breaking O’Brien appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
