Roy H

Roy H then received an extended layoff, during which time he was gelded.[5] Roy H returned to racing on April 8, 2017 in an allowance optional claiming race at Santa Anita. Back on the downhill turf course, he raced four-wide around the turn and then kicked clear in the stretch to win by ​2 ¹⁄₂ lengths.[9] He made his next start on May 6 in a race that was switched from turf to dirt due to rain. Over the wet-fast main track, Roy H "freaked", unleashing a powerful finishing burst to win by ​7 ¹⁄₄ lengths while earning a Beyer Speed Figure of 106.[8][10]

For his next start, Miller decided to ship the gelding to Belmont Park in New York for the True North Stakes, run over the dirt at a distance of six furlongs. Roy H faced two top sprinters, Stallwalkin' Dude and Whitmore, and went off at odds of 6-1. He raced in mid-pack for the first quarter of a mile, then started his move five-wide around the turn. He pulled away at the head of the stretch, then withstood a late run from Stallwalkin' Dude for a ​2 ¹⁄₂-length win.[6] His time of 1:08.59 earned him a Beyer Speed Figure of 111, one of the best ratings for a sprinter in 2017.[11]

Roy H then returned to California for the Bing Crosby Stakes at Del Mar on July 29. He went off as the 8-5 favorite in a nine-horse field that included the 2016 champion sprinter Drefong (Breeders' Cup Sprint) and Ransom the Moon (Kona Gold Stakes). Roy H broke well and vied for the early lead with St. Joe Bay. On the other hand, Drefong ducked in at the start and dumped his jockey. Riderless, Drefong caught up with the early leaders down the backstretch but drifted wide around the final turn, forcing Roy H even wider. Ransom the Moon, who was tracking the pace, ran through the gap on the rail and inherited the lead. Roy H tried to close ground but came up short by ​1 ¹⁄₂ lengths. "My horse was running really well and then the loose horse changed everything," said jockey Paco Lopez. "I was trying to work around him, but we just kept getting pushed out. ... What can you do?"[12] Roy H was racing for the Rockingham Ranch, and managed by Brian Trump.[13]

On October 9, Roy H made his next start in the Santa Anita Sprint Championship. Ridden for the first time by Hall of Fame jockey Kent Desormeaux, he was the odds-on favorite in a field of six. He tracked the early pace set by American Anthem and Mr. Hinx, moving easily while racing three-wide around the turn. In mid-stretch, Desormeaux hit him once with the whip and Roy H responded by pulling away for a one-length victory. "He's fast," said Desormeaux. "He probably broke a half a length behind the leaders and I had him in absolute reserve all the way."[14]

The field for the Breeders' Cup Sprint, held on November 4 at Del Mar, featured the top sprinters from across North America. Drefong was the favorite based on his win in the Forego Stakes in August and his excellent workouts. Other top contenders included Imperial Hint (five straight wins including the Smile Sprint), Takaful (Vosburgh) and Mind Your Biscuits (Dubai Golden Shaheen and Belmont Sprint Championship).[11] Imperial Hint broke quickly from the outside post and vied for the early lead with Takaful, who ran the opening quarter in a swift :21.82. Roy H scrambled to get good position then settled just behind them in third. Rounding the turn, Imperial Hint moved to the lead while Roy H swung wide. Roy H started his move as they entered the stretch and steadily pulled away to win by a length.[15]

"I had to jockey for position, fighting for a spot two times in 200 yards," said Desormeaux. "After that, he had the catbird seat. He raced off my fingertips and gave me a lovely ride. Absolutely exploded turning for home."[4]

Roy H earned a Beyer Speed Figure of 111, matching his career best.[16] The Racing Post assigned a rating of 128, tying him world-wide with Harry Angel for the top sprint performance worldwide in 2017.[17]

Roy H was named the American Champion Sprint Horse of 2017 at the Eclipse Award ceremonies in January 2018.[18]

Roy H began his six-year-old campaign in the Palos Verdes Stakes at Santa Anita on February 3, winning easily by ​3 ¹⁄₂ lengths. Miller planned to next start the gelding in the Triple Bend Handicap in March,[19] but ultimately scratched from that race. Instead he travelled to Meydan Racecourse for the Dubai Golden Shaheen on March 31. He broke poorly, costing him about eight lengths. He made up most of that ground as they rounded the turn, then entered into a stretch duel with XY Jet. Both horses were caught near the finish line by Mind Your Biscuits, who had made a late run to win the race for the second time. Roy H finished third, beaten by less than a length.[20]

On returning to America, Roy H was given some time off, then returned in the Bing Crosby Stakes on July 28. His main rival was Ransom the Moon, who had won the race in 2017 after Roy H was interfered with by Drefong. This time, Roy H raced in fourth behind the early leaders then made his move in the stretch. However, he lacked his usual closing kick and finished second to Ransom the Moon. Desormeaux felt that the gelding needed the race after the long layoff and would improve in his next start.[21]

Now ridden by Paco Lopez, Roy H made his next start in the Santa Anita Sprint Championship on October 6. Racing three wide, Roy H settled in third place then moved to the lead as they entered the stretch. He won by ​2 ³⁄₄ lengths over stablemate Distinctive B, with Ransom the Moon closing late to finish third. Lopez commented that Roy H was "an easy horse to ride" and could be positioned "pretty much anywhere", letting the jockey adjust tactics as the race developed.[22]

Roy H entered the 2018 Breeders' Cup Sprint on November 3 at Churchill Downs as the second favorite behind Imperial Hint. Roy H broke poorly and bumped into the starting gate but soon recovered his stride and took the lead while racing four wide around the turn. He continued to draw away down the stretch, winning by ​3 ¹⁄₄ lengths over Whitmore, with Imperial Hint finishing third. "He charged today," said Lopez. "That horse won today with no problem. He knows what's going on today. He dances. He's very happy today."[23]

After the race, Miller laughed at the pre-race commentary regarding Imperial Hint, who had won several major races on the East Coast including the Vosburgh Stakes "Well, the East Coast horses get the hype, and the West Coast horses get the money," he said. "You guys can hype all you want our here. We'll take the money with us."[24]

Roy H was named the American Champion Sprint Horse of 2018 at the Eclipse Award ceremonies in January 2019.[25]

Roy H started his seven-year-old campaign on January 19, 2019 in the Palos Verdes Stakes, going off as the 1-5 favorite. He ran to his odds, drawing off under a hand ride to win by four lengths.[26] He was next scheduled to run in the Dubai Golden Shaheen but was withdrawn after an abscess was discovered on his left front hoof.[27] Although Roy H missed months of training due to the issue, Miller still holds out hopes of making it back to the Breeders' Cup in November. "He has to breeze every six or seven days and not have any hiccups," Miller said on September 20, in advance of a scheduled workout.[28]
