Jockey Kayla Stra Out With Thumb Injury

Jockey Kayla Stra is expected to miss up to 10 days with a dislocated right thumb suffered when her mount, Russian Silk, broke down passing the quarter pole in the ninth race March 29 on the Santa Anita Park turf.

"I’ll probably name her on mounts a week from Thursday," agent Richie Silverstein said. "I won’t be taking mounts this Friday and Saturday."

Added Stra: "The dislocation retracted quickly; it’s more like a sprain."

Stra, 29, is from Adelaide, South Australia, where she began her riding career. She started riding in North America in 2007 and has been part of the Southern California jockey colony for most of that time.

She has won 143 races, according to Equibase, from 1,891 mounts with purse earnings of $3,738,785. At the current Santa Anita meet, she has won with six of 68 starts.
