A single 10-cent winning ticket on Gulfstream Park’s Rainbow 6 wager returned $791,364.73 Sunday to one bettor.

The innovative 10-cent Rainbow 6 wager, introduced in 2011 at Gulfstream, requires a bettor to pick the winners of the last six races on the program. The jackpot is only paid out when there is one unique ticket with all six winners. The carryover built last winter to $5.1 million.

Gulfstream resumes racing Thursday, April 5. There will be a mandatory payout of the Rainbow 6 on Saturday, April 7. Gulfstream’s closing day of live racing will be Sunday, April 8.

Redemption: Darley Stable’s 3-year-old Sensor made a less than auspicious career debut Feb. 11 when finishing sixth of eight at Gulfstream Park. But he got it together Sunday breaking his maiden in the fifth race maiden special weight test as he drew off to score by 1 ½ lengths over Pam and Martin Wygod’s Key to Power going 1 1/8 miles under jockey Elvis Trujillo.

A Kentucky homebred colt by 2007 Kentucky Derby (G1) winner Street Sense, Sensor had finished a well-beaten sixth as a 33-to-1 longhshot going seven furlongs on a ‘sloppy’ track in his only previous start for trainer Tom Albertrani, but obviously benefited from the experience and appreciated that additional distance of Sunday’s race.

Sensor paid $14.80 for $2 to win and was timed the distance in 1:52:56 over the ‘fast’ track. Tom Walter’s Entrainment finished third, 2 ¾ lengths behind the runner-up in the field of six 3-year-olds as Hurricane Boys Racing Stable and Hank Steinbrenner’s 3-to-10 favorite Tiz Yankee finished a disappointing fifth after setting the pace to the top of the stretch.

Quote of the Day: Trainer Tom Albertrani after Sensor maiden special victory in the fifth race: “We always thought a lot of him in the mornings before he raced and was one of the few we nominated at the early closing of the Triple Crown races. He was very green for his first start, but came over on his game today. His pedigree suggested he would like the longer distance. I think he’s going to be a nice colt.”

Who’s Hot: Jockey Elvis Trujillo won two races with Face Card for Eddie Coletti in the second and Sensor in the fifth for trainer Tom Albertrani.

Work of the Day: Michael Lauffer and W.D. Cubbedge’s 4-year-old Shackleford drilled a ‘bullet’ half-mile in 47 1/5 Sunday morning at Gulfstream Park for trainer Dale Romans, fastest of 28 horses timed at the distance as a final tune-up for a start in the $250,000 Carter Handicap (G1) at Aqueduct next Saturday.

A chestnut colt by Forestry, Shackleford scored his biggest victory in Preakness Stakes (G1) at Pimlico last spring. He will bid to bounce back from a disappointing effort last out when seventh as the lukewarm favorite in the $500,000 Donn Handicap (G1) here on Feb. 11, his first start since finishing third in the Breeders’ Cup Dirt Mile (G1) at Churchill Downs on Nov. 5.
