The trainers enshrined in the National Museum of Racing's Hall of Fame all have one thing in common: They have been based in North America, which is fine. The Hall of Fame is supposed to recognize those whose accomplishments in racing on these shores have made them among the best of all time.But it's time to make an exception, which, actually, might not really be an exception. Follow along.Aidan O'Brien is based in Ireland and the vast majority of his success has come in European races. O'Brien is an inductee in the QIPCO British Champions Series Hall of Fame, but it's time that his success in the U.S., and in particular in the Breeders' Cup, be recognized. After another incredible Breeders' Cup run last week at Keeneland, which included three more victories, he has tallied 24 wins overall. That makes him the winningest trainer in Breeders' Cup history. He is followed by Bob Baffert (22), Chad Brown (21), Wayne Lukas (20), Bill Mott (17), Todd Pletcher (16) and Brad Cox (13). Baffert, Lukas, Mott and Pletcher are in the Hall of Fame. Brown will be as soon as he is eligible for induction andf Cox is a safe bet to make the Hall of Fame.In addition to his Breeders' Cup victories, O'Brien has won a a slew of Grade I races in the U.S. He's won the Arlington Million twice, the Shadwell Turf Mile twice, the Secretariat Stakes four times and has also won the Joe Hirsch Turf Classic, the Man o'War, the Sword Dancer and a bunch of others.True, nothing that he has accomplished outside of North Americas should count when it comes to his candidacyfor the Hall of Fame. And true, there seems to be an unwritten rule that foreign-based trainers are not eligible for the North American Hall of Fame. But it is just an unwritten rule.O'Brien is the leading trainer in Breeders' Cup history in wins with 24. That should be enough to get inducted into the Hall of Fame.Into Mischief Is Now the Leading General Sire in America by EarningsInto Mischief passed Not This Time in the category of the leading general sire in America by earnings for 2026. He moved past his rival thanks to wins by Sovereignty in the GI Breeders' Cup Classic and Hughes in the GI Breeders' Cup Juvenile and heads into this week with a lead of $550,361.Into Mischief has won the title seven straight years and is the first horse to achieve that feat since Bold Ruler.The TDN and other publications are not on the same page when it comes to how earnings are computed. This publication credits the offspring of sires for every dollar (after taking currency conversion rates into account) they have earned in foreign countries like Japan and Hong Kong. Others will adjust those earnings based on the belief that purses are inflated in some other countries.Billy Loughnane's Fight to Lose Weight is Not a Feel-Good StoryThe 20-year-old phenom Billy Loughnane cannot be blamed for doing whatever it took to make the weight so that he could ride Libertango (Ire) (No Nay Never) in the GI Breeders' Cup Juvenile Turf Sprint. He had ridden the horse in all five of her career starts and obviously wanted to stick with her in a race where she looked like the one to beat.Loughnane was able to make 119 pounds and rode Libertango to victory, but it took a lot of doing. Loughnane had been riding at 122 pounds entering the Breeders' Cup and thought that the best he could do was to get down to 120 pounds. That's why trainer George Boughey named Flavien Prat to ride the 2-year-old filly.Libertango and Billy Loughnane | Walter WlodarczykLoughnane did what jockeys do. He hit the gym, he baked in the sauna, he likely ate next to nothing. It worked. He made the 119 pounds assigned to the filly, and, at the last minute, was given the mount back.But this is not how it should be. Loughnane is 5-foot-10 and no one who is that tall should weigh 119 pounds. It's just not healthy. Neither is pushing his body to the limits so that he could lose some three pounds over a short period of time.This may not be the time to raise the issue of raising the scale of weights for jockeys throughout the sport, but the Breeders' Cup can make a meaningful change on its own. With so many European jockeys, who tend to weigh more than their American counterparts, participating, the Breeders' Cup should look at raising the weights make the top weight in all races 126 pounds. It's already the standard in the GI Kentucky Derby and the Breeders' Cup Classic, and Libertango had carried 128 pounds in all five starts in Europe. Why make the top weight for the Juvenile Sprint 122 pounds–especially when it is a race that attracts a lot of fillies? They carry only 119 pounds.On Saturday, Loughnane rode at 126 aboard Comanche Brave (Ire) (Wootton Bassett ({GB}) in the GI Breeders' Cup Turf Sprint. Let's hope he had a nice big diner Friday night. He certainly deserved it.DJ Stable Gets ItThe sport could use more owners like the Green family's DJ Stable. More so than any major outfit in the sport, they are willing to test their horses rather than baby them. It's called sportsmanship, and it is, as they say, good for the game.We already saw it this year when they sent Nitrogen (Medaglia d'Oro) out to battle Sovereignty in the GI Whitney Stakes. She finished second, but it was an effort that only enhanced her reputation. The Greens announced earlier in the year that Nitrogen would run again next year at five, and after her win in the GI Breeders' Cup Distaff, Jon Green floated the idea of her running next year in the Classic.On Sunday, Green told the Breeders' Cup notes team that Nitrogen may make her next start against males in the 2027 GI Pegasus World Cup.“If she wants to, and she tells us that she's ready, the plan is to run her in January, probably in the Pegasus against the boys,” Green said. “And then we'll see, kind of take it race by race. But we have a couple of races in mind for 2027 that hopefully will bring her back to the Breeders' Cup at Belmont.”Another Perfectly Safe Breeders' CupThere were once again a number of pre-race scratches from Breeders' Cup races, but that doesn't mean that the vets and regulators aren't getting things done right. A total of 157 horses ran in this year's Breeders' Cup races and all 157 apparently returned to their barns safe and sound. That's a stat that the Breeders' Cup and the sport can be proud of.The post Week in Review: Let’s Open the Doors to (Our) Hall of Fame to Aidan O’Brien appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
