Whosleavingwho wins Los Alamitos Winter Championship


LOS ALAMITOS, Calif. - Whosleavingwho, the co-World Champion Quarter Horse of 2002, won his 2003 stakes debut in Saturday's $206,000 Los Alamitos Winter Championship for older Quarter Horses.

Ridden by Joe Badilla, Jr., the 5-year-old Whosleavingwho ($2.80) ran 400 yards in 19.483 seconds, scoring by a length over Agouti, a stakes winner in December.

Trained by Paul Jones, Whosleavingwho did not have an ideal start, but quickly recovered and led by three-quarters of a length midway through the race.

Agouti finished a nose in front of Chicks Rapidash, a 59-1 shot, giving Jones a sweep of the first three positions.

The victory gave Whosleavingwho an automatic berth into the $500,000 Champion of Champions on Dec. 13, a race he won last December. Owned by Jim Geiler and Kim Kessinger, Whosleavingwho has won 15 of 28 starts and $855,083. Last year, he shared the World Championship title with Streakin Sin Tacha.
