ARCADIA, Calif. (April 15, 2011) – Dismissed at odds of 13-1 in her United States debut, British-bred Fifth Ave overwhelmed 3-5 favorite Rumor by 1 ¼ lengths to capture Friday’s $56,000 American Girl Purse for 3-year-old fillies at 6 ½ furlongs over Santa Anita’s downhill turf course and keyed a Pick Six carryover into Saturday of $63,809. I

It’s expected the total Pick Six pool on Saturday could exceed $500,000.

After Rumor found an opening along the rail to bid for the lead entering the stretch run, Fifth Ave rallied more strongly on the extreme outside under jockey Mike Smith to become dominant in the field of five.

Trained and co-owned by Jim Cassidy after being purchased in England early this year, Fifth Ave had raced 13 times without particular distinction in England between May and October of 2010 before getting a freshening and being transported to the U.S.

“This was a surprise,” Smith said in the winner’s circle. “Jim (Cassidy) is so great at buying these kinds of horses. She was so professional. She was good with the pony and she warmed up great. We left the gate really well, and she came down the hill like she’d been there before. I don’t know how far she’ll run, but today it was good enough.”

Rumor, a dazzling maiden winner last December before being edged at odds of 2-5 in her second race, failed to gain atonement in her third start, but held on for second, three lengths ahead of Up In Time, ridden by Martin Garcia.

The longest shot in the field at double the odds of the next longest, Fifth Ave paid $28.80, $6.40 and $3.20. Rumor returned $2.60 and $2.20. Up In Time paid $2.80 to show.

After earning $24,131 with a 2-2-3 record in her 13 races in the United Kingdom, Fifth Ave banked $33,600 in her U.S. bow for Cassidy and co-owner Paula Regina.

The final weekend of Santa Anita’s 2010-11 season commences on Saturday with a 10-race program featuring the Grade II, $150,000 Santa Barbara Handicap and the Grade III, $100,000 San Simeon Handicap. First post is at 12:30 p.m.
