Magician, a 3-year-old colt from Ireland, got by the English-based filly The Fugue to score by a half length. Indy Point, an Argentine-bred runner, finished third.
Point of Entry was fourth, the best showing of any U.S. runner in the 1 1/2-mile test over the firm Santa Anita turf.
Magician, a 12-1 long shot, finished in 2:23.23 with Ryan Moore up for trainer Aidan O'Brien. The son of leading European sire Galileo won the Group 1 Irish 2,000 Guineas at the Curragh in May but then was never a factor in his only intervening race, the Group 1 St. James' Palace Stakes at Royal Ascot in June. Overall, he now has four wins from eight career starts.
Magician stayed comfortably at the back of the 12-horse field for much of the race, biding his time behind a fast early pace. As the field entered the stretch run in the Turf, it appeared last year's winner, Little Mike, was on his way to a repeat win as he took over from the early leader, Teaks North. But he quickly was swallowed up by the foreign contingent, headed by The Fugue.
Moore got Magician to the outside at the top of the lane but was still a good 6 lengths behind at mid-stretch. He quickly began to cut into that lead under a confident ride and won in a hand ride.
Little Mike finished seventh. Real Solution, who won the Grade I Arlington Million on a disqualification, struggled home ninth.
