Watch Out World, a 2-year-old half-sister to Cavonnier, the 1996 Santa Anita Derby winner who nearly won the Kentucky Derby, won the second straight race of her career Wednesday, a $42,900 allowance race at Golden Gate Fields.Bred and owned by Robert and Barbara Walter, who also campaigned Cavonnier, Watch Out World was ridden to victory by Jose Rivera Jr. by a head over Lucky Sabre at odds of 9-5. The California-bred daughter of Slewvescent out of the Caveat mare Direwarning was timed in 1:09.81 for six furlongs.The filly, known locally as "WOW" for her acronym, debuted with a 3/4-length maiden victory Oct. 20 for trainer Armando Lage. She was entered in the Piedmont Stakes at Golden Gate Nov. 23, but flipped in the paddock and was scratched. Wednesday's victory was an eventful one. Watch Out World was hand ridden to the wire when jockey Rivera lost his whip after getting tangled with Lucky Sabre and jockey Russell Baze.Cavonnier is the best horse the Walters, among Northern California's most successful breeders, have raced. An outsider in spite of his win in the Santa Anita Derby (gr. I), he lost a photo by a nose to Grindstone in the Kentucky Derby (gr. I), one of the closest finishes in the classic's history.Watch Out World paid $5.80 and $3.80. Lucky Sabre, the 3-2 favorite, returned $2.80. There was no show wagering after two scratches reduced the field to four.
