There’s nothing synthetic about In Summation except the racing surface he fancies.

In 27 career starts, the 6-year-old Florida-bred horse has had 10 on synthetic surfaces, winning five, with two seconds and one third. In five starts on Santa Anita’s synthetic track, In Summation has three victories, including back-to-back scores in the Grade III El Conejo Handicap at 5 ½ furlongs.

This Saturday, the winner of the Grade I Bing Crosby Handicap at Del Mar in 2007 (he was second last year) seeks a victory in one of his major objectives: the $300,000 Sunshine Millions Sprint at six furlongs.

In Summation is trained by Christophe Clement, whose base of operations is on the East Coast. But the 43-year-old native of Paris has found a home for In Summation on the West Coast. In Summation is one of seven Clemente horses at Santa Anita with assistant Nicholas Bachalard. The reason: In Summation is a synthetic sprint specialist.

“There aren’t too many sprints on synthetic tracks on the East Coast,” Bachalard said. “That’s one of the reasons In Summation was brought here; he has many more options. The only synthetics back east are Keeneland and Arlington (both Polytrack) . . . so the logical place for In Summation is here. Arlington only had one sprint stakes and they moved it from synthetic to the grass. That’s why we brought In Summation here.”

In Summation has an 11-6-1 record from 27 starts, with earnings of $1,175,166 for the Waterford Farm of Thomas Moore of New York City.

The field for the Sprint: Big Bad Leroybrown, Joe Talamo; Carnacks Choice, Eibar Coa; Machismo, Mike Smith; Partywithlarryz, Tyler Baze; Sok Sok, Shaun Bridgmohan; Cape Hatcher, Michael Baze; Georgie Boy, Garrett Gomez; Devoted Magic, Joel Rosario; In Summation, Rafael Bejarano; Dancing In Silks, Victor Espinoza; and Yesbyjimminy, Elvis Trujillo.

In other Sunshine Millions news:

Romance Is Diane, a favorite in the $500,000 Distaff, was declared out of the race Monday morning. “I planned to blow her out this morning but she has some heat in a leg so we’re probably going to retire her,” trainer Mike Mitchell said. “I called one of Mr. Stronach’s managers and told him of the news. I don’t want to risk running under the circumstances.”

Romance Is Diane, a 5-year-old California-bred mare by In Excess, was purchased for $1,350,000 by Frank Stronach after her second-place finish by a head against males in the California Cup Classic at Oak Tree last Oct. 5. She has a 5-2-1 record from 16 starts, with earnings of $712,718.

Georgie Boy (Sprint) worked four furlongs Monday at Hollywood Park in :47.80, breezing, for Kathy Walsh.

Ben Cecil is optimistic that Waveline can successfully go from six furlongs to a mile and a sixteenth in the Distaff. The 4-year-old California-bred daughter of Stravinsky is coming off two victories at six furlongs, one on turf, the most recent on Cushion Track at Hollywood Park.

“We’re stretching her out,” Cecil said. “That’s always a question mark when you’ve never done it before, but she worked very well (Sunday, five furlongs on Pro-Ride in :59.60). I got her after Woodbine and we had to stop and take a chip out of her knee. She’s won both starts back.”

Rafael Bejarano rides.

Trainer Vladimir Cerin on Distaff contender Briecat, a Florida-bred daughter of Adcat with a three-race winning streak: “She ran 10 times as a 3-year-old. She’s ready to roll.” Briecat worked five furlongs on Santa Anita’s training track Sunday in 1:00.20. Jon Court has the mount.

First post time Sunshine Millions Day is 11:45 a.m. Gates open at 10 a.m. All THOROUGHBREDS members in attendance will receive the free the official Sunshine Millions AM/FM Beach radio with paid admission while supplies last.

The popular Miss Sunshine Millions Pageant and the Santa Anita Handicapping Contest also will take place Saturday at Santa Anita.

FINISH LINES: Today’s Pick Six carryover of $141,431.42 is the ninth in 19 days at the current meet . . . European import Zambesi Sun worked six furlongs on Pro-Ride Monday in 1:14.60 for Bobby Frankel, who said the well-regarded son of Dansili is a candidate for the $1 million Santa Anita Handicap on March 7 . . . Breeders’ Cup Juvenile Fillies champion Stardom Bound worked five furlongs for Frankel under Goncalino Almeida in 1:00.80 as she readies for her 3-year-old debut in the Grade I Las Virgenes Stakes at one mile on Feb. 7 . . . She’s Cheeky, prepping for the Grade I Santa Monica Handicap on Jan. 31, worked five furlongs for Peter Eurton in 1:01 . . . Tyler Baze won three races Saturday, including the Grade II Santa Ynez Stakes on Alpha Kitten. The 26-year-old rider was sidelined by injuries for nearly two months until he returned at Santa Anita on Jan. 7. “It’s never easy to come back after being out,” said Tyler’s agent, Ron Ebanks. “The amount of opportunity was thin in the beginning, but I told him, ‘We’re probably better off. We’ll just take our time riding one or two a day for the first five or six days and make sure we’re 100 percent and feeling good. We’ll kind of hand-pick our spots, try and get some live ones and try to get a win or two early and get off the ground.’ That’s worked. He’s got his built-in clients and he’s got good customers who support him.” . . . Santa Anita is dark Tuesday and Wednesday. Racing resumes Thursday at 1 p.m.
