Katdogawn takes Santa Ana

Odds-on favorite Megahertz is disqualified for interference in the Grade 2 Santa Ana Handicap on Saturday. Katdogawn wins the $150,000 race.

ARCADIA, Calif. - The best horse crossed the wire first in the Grade 2 on Saturday at Santa Anita. However, Megahertz racked up two rivals at the head of the stretch in the mile and an eighth turf stake for fillies and mares, and it took stewards just five minutes to disqualify the odds-on favorite from first and place her last for interference, which resulted in Katdogawn inheriting the win in the $150,000 race.

Megahertz's regular rider Alex Solis was in Dubai on Saturday, and Victor Espinoza was riding Megahertz for the first time. The Bobby Frankel-trained mare launched a five-wide rally on the far turn, hit the stretch six-wide with a head of steam, but swerved in sharply and impeded Arabic Song and Sweetshew, who finished last. Stewards placed Megahertz behind Sweetshew.

It was Katdogawn ($12.60) who was in the right place at the right time. Given a ground-saving trip under Mike Smith, she finished one length behind Megahertz, and inherited the win for trainer Jim Cassidy. Original third-place finisher Fun House was moved up to second; Arabic Song was moved from fourth to third. Katdogawn was winning her third Grade 2 since Cassidy imported her from England. The 4-year-old filly has won six of 17 overall, and earned $450,645.

* A fast allowance route race for 3-year-olds stole the show from the low-rated San Pedro Stakes for 3-year-old sprinters earlier on the card. Boomzeeboom shook loose on an easy lead to win race 6 by a half-length under Corey Nakatani; runner-up Minister Eric, ridden by Victor Espinoza, served notice he may be Kentucky Derby material. Wide throughout, Minister Eric finished eight lengths clear of third. Boomzeeboom's time was a quick 1:41.97. Richard Mandella-trained Minister Eric was making his second start since a runner-up finish in the Breeders' Cup Juvenile; Boomzeeboom, trained by Vladimir Cerin, was stretching out following a maiden sprint in which he earned a 106 Beyer.

* In the $83,625 San Pedro Stakes, Courageous Act ($11) wore down longshot Wimplestiltskin stretch to win the six and a half-furlong race by three-quarters of a length in a modest 1:16.13. Javiar Santiago rode the winner for Bob Baffert. After the runner-up, it was a half-length back to Stalking Tiger. Jimmy's Instinct, the 8-5 favorite, failed to show speed and finished fifth, beaten more than eight lengths.
