Baffert said the colt would be pointed toward the Pacific Classic at Del Mar on Aug. 22.
He was last year’s champion 3-year-old after crossing the finish line first in the Kentucky Derby only to be disqualified for interference.
It was Maximum Security’s first U.S. start of the year after a victory in the $20 million Saudi Cup on Feb. 29 for trainer Jason Servis. After that race, owners Gary and Mary West and their partners transferred their colt to Baffert when Servis was indicted on charges of administering illegal medications in March.
Maximum Security ran in the colors of partner Coolmore, where he will go to stud in Kentucky next year.
Midcourt returned $3.60 and $2.10. Higher Power paid $2.10 to show. Ax Man, also trained by Baffert, was fourth and Combatant fifth.
The Grade 2 race was postponed a week after Del Mar was forced to cancel racing when 15 jockeys tested positive for COVID-19.
