INGLEWOOD, Calif.—Shared Belief romped to a record 7 3/4-length victory in the $100,000 Hollywood Prevue Stakes for 2-year-olds at Betfair Hollywood Park on Sunday.

Ridden by Corey Nakatani, Shared Belief ran seven furlongs on Cushion Track in 1:22.17, the fastest time in the Grade 3 race since 2008 when Jack O'Lantern won in 1:21.89. The old record for winning margin was six lengths by Lion Heart in 2003.

Shared Belief paid $5, $2.40 and $2.10 as the 3-2 second choice. He is co-owned by sports talk host Jim Rome and Hall of Fame trainer Jerry Hollendorfer.

Kobe's Back, named for Los Angeles Lakers superstar Kobe Bryant, returned $2.20 and $2.10 as the 9-10 favorite. Brother Soldier was another 4 3/4 lengths back in third and paid $2.80 to show.

Lee Searing, who co-owns Kobe's Back, was so sure of Bryant's return that he named the horse shortly after the guard tore his ACL in April. Bryant has yet to play this season.

Shared Belief is 2-for-2 in his brief career and has earnings of $76,200.

"That was an impressive 2-year-old right there," Nakatani said. "He was very focused. When I worked him he did everything so easily, but I didn't ride him the first time and I didn't know he'd be so relaxed. When they do the things this horse did today, it's pretty exciting."
