Unbridled Is Upset by 15-1 Shot : Super Derby: His stablemate, Home At Last, wins by 3 1/2 lengths. Cee’s Tizzy is third.

Unbridled went off as the odds-on favorite, but his stablemate stole the show in the $1-million Super Derby at Louisiana Downs Sunday.

Home At Last broke out of the pack after a mile and scored a 3 1/2-length victory over Unbridled in the season’s last major race limited to 3-year-olds. Overnight favorite Summer Squall, the Preakness winner, was scratched because of a slight fever.

“(Home At Last has) been ignored all along, but I think he’s as honest a horse as you can find,” said Carl Nafzger, the trainer of both Home At Last and Kentucky Derby winner Unbridled. “I told people all week he was a joke in the morning line at 20-to-1.”

Jerry Bailey gave Home At Last a perfect trip, saving ground until taking the lead with a quarter of a mile to go. “I was going to take him back after the break, but I didn’t want to get in all that traffic,” Bailey said. “I knew there were quick fractions, but he was running easy. Every time I asked him for more, it was there.”

Unbridled ran last for a half-mile, was forced five-wide, couldn’t make up any ground until the stretch.

Home At Last’s winning time for the 1 1/4 miles was 2:02, well off the Super Derby record of 2:00 1/5 by Gate Dancer in 1984.

Southland-based Cee’s Tizzy, who set early fractions of 22 4/5 and 45 2/5--both Super Derby records--held on for third.

Home At Last, who came in with career earnings of $346,675 on four victories in 11 career starts, earned $600,000. He paid $33.60, $7.20 and $4. Unbridled returned $3 and $2.40 and Cee’s Tizzy paid $3.40.
