Arrogate, who was honored as the 2016 Longines World’s Best Racehorse, continued his winning ways to begin this year. In his first start of the season, the 4-year-old colt by Unbridled’s Song pulled away to win the Grade 1 Pegasus World Cup by 4 3/4 lengths despite being geared down in the final sixteenth of a mile by Hall of Fame jockey Mike Smith.
Arrogate is expected to make his next start in the Dubai World Cup Sponsored by Emirates Airline on March 25.
