ARCADIA, Calif. (Jan. 7, 2010) – Dotsy Jean, claimed by trainer Marty Jones one year ago on behalf of AJM Racing for $16,000, boosted her earnings since the claim to $151,108 with a 5-1 upset victory Thursday in Santa Anita’s $59,102 optional claiming feature for fillies and mares at six furlongs.

The 5-year-old California-bred daughter of Breeders’ Cup Sprint champion Lit de Justice defeated Sleep Tight by 1 ½ lengths with Joel Rosario at the controls and covered the distance in 1:09.20. Emmy Darling picked up third, 1 ¼ lengths behind Sleep Tight in the field of six. Dotsy Jean has been remarkably consistent while racing for Jones since last January. The grey mare has finished worse than third but once in nine races while winning five times.

Her victory on Thursday marked a return to Santa Anita’s Pro-Ride surface over which she had won her first start for AJM Racing. Dotsy Jean’s next seven starts were contested over grass.

Rosario had her placed in second behind Gambler’s Justice in Thursday’s feature. She took command entering the stretch and won with authority.

Dotsy Jean returned $12.20, $5.20 and $3.20. Sleep Tight, ridden by Michael Baze, paid $5 and $3.40. The show price on Emmy Darling, with Rafael Bejarano aboard, was $3.20. Sleep Tight, the only competitor entered for a claiming tag of $62,500, was not taken.

With the winning purse of $38,220, Dotsy Jean increased her career earnings to $198,690 from an overall record of 8-5-5 in 26 starts.

On Friday, Santa Anita launches the first of its weekly Free Friday attractions while offering free General Admission, free box seats on a first-come, first-served basis, and hot dogs, beer, sodas, popcorn and coffee at a cost of $1. First post for the card of eight races is at 1 p.m.
