ARCADIA, Calif. (AP) _ Lady's Secret, who won 10 stakes races in 1985, on Sunday scored her second victory in as many tries this year when she captured the $205,700 La Canada Stakes at Santa Anita.

Ridden by Chris McCarron, Lady's Secret took the lead early in the 1 1/8 -mile event and held on to take a 1 1/4 -length victory over Shywing.

North Sider finished third, four lengths back of Shywing, in the six-horse field of 4-year-old fillies.

Carrying high weight of 126 pounds, Lady's Secret was clocked in 1:49 4-5.

The heavy wagering favorite of the Santa Anita crowd of 43,665, Lady's Secret returned $3, $2.20 and $2.20. Shywing, ridden by Laffit Pincay Jr. and carrying 119, paid $2.60 and $2.40. North Sider, ridden by Eddie Delahoussaye and carrying 118, paid $2.40.

The runnerup to Mom's Command in the Eclipse balloting as the nation's outstanding 3-year-old filly last year, Lady's Secret had won the El Encino Stakes at Santa Anita in her only other 1986 start.

In the La Canada, Lady's Secret moved ahead immediately after the start, with Time For A Slam and Shywing close behind. Running smoothly on the inside, Lady's Secret pulled away going into the final turn, then held off a stretch bid by Shywing.

Time For A Slam finished fifth behind Lucky Roberta, with Oriental last.

Lady's Secret, owned by Mr. and Mrs. Eugene Klein and trained by D. Wayne Lukas, now has won 15 of 27 career starts and has earned more than $1.25 million, including the $120,200 winner's purse in the La Canada.

Videogenic, expected to provide the stiffest competition for Lady's Secret in the Santa Anita stakes race, was scratched. She had won the $150,000-added Orchid Handicap at Gulfstream Park in Florida recently and had been assigned co-highweight of 126 for the La Canada.

She was scratched when her trainer, Gasper Moschera, decided not to challenge Lady's Secret under equal weights.
