DEL MAR, Calif. — There's a new king in horse racing and it's Gun Runner. The 4-year-old colt won the $6 million Breeders' Cup Classic by 2¼ lengths Saturday, sending rival Arrogate to a third straight career-ending defeat at Del Mar. Gun Runner ran 1¼ miles in 2:01.29 and paid $6.80, $4.40 and $3.20. Collected returned $5.60 and $4, while West Coast was another 1¼ lengths back in third and paid $3.60. Arrogate finished in a dead-heat for fifth with Gunnevera, done in once again at the seaside track north of San Diego. It was the scene of two losses during the summer. "He just doesn't seem to get a hold of this racetrack, for whatever reason," jockey Mike Smith said. Arrogate hasn't been the same horse since his dominant wins in the $12 million Pegasus World Cup and the $10 million Dubai World Cup earlier this year that made him the sport's richest thoroughbred with more than $17 million in earnings. Dubai was the last time Gun Runner lost. Since then, he has emerged stronger than ever with four straight wins. Arrogate was a slight 2-1 favorite over Gun Runner. Trainer Bob Baffert saddled a record four horses in pursuit of a record fourth straight win in the Classic. He finished 2-3 with Collected and West Coast, and was left to puzzle over another disappointing showing by Arrogate. His other horse, Mubtaahij, was eighth. In other races: • Good Magic won the $2 million Juvenile by 4¼ lengths, making him the winter favorite for the Kentucky Derby.• Trainer Peter Miller went 1-2 in the $1 million Turf Sprint with 30-1 shot Stormy Liberal winning by a head.
