ELMONT, N.Y. - After missing a workout last weekend, Complexity put himself back in the mix for the $1 million Breeders’ Cup Dirt Mile by working a half-mile in 48.85 seconds Sunday morning over the Belmont Park main track. In his first work since winning the Grade 3 Kelso Handicap on Oct. 3, Complexity went his first quarter in 25.39 seconds, came home in 23.46 and galloped out five furlongs in 1:01.70. “He had a minor issue come up last weekend where I didn’t feel comfortable working him,” trainer Chad Brown said. “He had a nice week of training this week and breezed fantastic this morning. As long as he comes out of it well, he will be pre-entered tomorrow.” Brown said Complexity would be pre-entered only for the Dirt Mile. The Sprint had been a second option. :: Enhance your handicapping with DRF’s Belmont Clocker Report Complexity is one of 13 horses Brown planned to pre-enter Monday for the two-day Breeders’ Cup event Nov. 6-7 at Keeneland. While Complexity worked on dirt Sunday at Belmont, Brown worked eight other Breeders’ Cup horses on the turf at Belmont. He also worked two horses at Keeneland. Two other of his Breeders’ Cup horses - Reinvestment Risk and Dunbar Road - worked on dirt Saturday at Belmont. Rushing Fall and Sistercharlie led the Brown parade on turf Sunday morning, working five furlongs together in 1:01.47, with a final quarter of 24.00 in preparation for the $2 million Filly and Mare Turf. Though the inner turf course was labeled firm, it was closer to good. Brown said Rushing Fall, who is 3 for 3 this year, “has been a model of consistency in her races and her works.” Sistercharlie, the 2018 BC Filly and Mare Turf winner, is 0 for 2 this year and will go into the Filly and Mare Turf having not run since she was third in the Grade 1 Diana at Saratoga on Aug. 23. Brown made a concerted effort to skip the Flower Bowl and bring her into the $2 million Filly and Mare Turf fresh. “So far, that decision based on the morning works is clearly the right one, because her last two workouts have been her best two workouts of the year,” Brown said. “The way she’s moving, she continues to train up to the race the right way.” My Sister Nat and Nay Lady Nay, second and third respectively behind Civil Union in the Grade 1 Flower Bowl on Oct. 10, worked a half-mile in company in 49.75 seconds, getting their final quarter in 24.09. They both are headed to the Filly and Mare Turf. Nay Lady Nay was a late addition to Brown’s line-up for the Filly and Mare Turf. That decision was made in part because there was no other race that made sense to Brown and her owners. “She’s been a very consistent filly and she’s an improving filly,” Brown said. “It’s one of those races where weather could play a factor, post position ... there are a lot of things going on in this race. I guess it’s worth a shot when you look at it that way.” Uni, seeking a repeat victory in the $2 million BC Mile, worked five furlongs in 1:01.56 in company with the 3-year-old Domestic Spending, a candidate for the Grade 1 Hollywood Derby at Del Mar. After a dull summer, Uni, coming off a win in the First Lady at Keeneland, seems to be thriving in the fall, prompting Brown to dub her “a female Reggie Jackson.” Jackson was nicknamed Mr. October due to his heroics in the World Series for the New York Yankees. BC Mile candidate Digital Age, coming off a win in the Grade 1 Old Forester Turf Classic at Churchill Downs on Sept. 5, worked five furlongs in 1:01.03 in company with Analyze It. “They broke off slow and they flew home,” Brown said. “Digital Age is an interesting horse cutting back to a mile, which he’s bred to do. He’s got plenty of rest, he’s coming off the fastest number of his life at Churchill.” Public Sector, runner-up in the Grade 2 Pilgrim, and Editor At Large, who was third in the Grade 2 Miss Grillo, went five furlongs together in 1:02.84. Public Sector is pointing to the $1 million Juvenile Turf; Editor At Large is targeting the $1 million Juvenile Fillies Turf. Editor At Large was under a stern hold from her rider. Brown said Editor at Large is the only one he will pre-enter in the Juvenile Fillies Turf. Fluffy Socks will stay in New York to run in next weekend’s Chelsea Flower. “I thought she worked exceptional today and we’re going to try and get her into the race if we can,” Brown said of Editor At Large. At Keeneland Sunday, Raging Bull worked a half-mile in 49.40 over the main track in preparation for the Mile, while Front Run the Fed went a half-mile in 49 seconds in preparation for the $1 million Turf Sprint.
