Proving just as tough to pass as he was in the Kentucky Derby (G1), 9-10 favorite Medina Spirit repelled Rock Your World to post a front-running victory in Sunday’s $100,500 Shared Belief S. at Del Mar.

As Medina Spirit awaits the adjudication of his first-past-the-post result in the Kentucky Derby (G1), the Bob Baffert trainee resumes his campaign in Sunday’s $100,000 Shared Belief S. at Del Mar.

The Kentucky Derby (G1) picture on the West Coast experienced a seismic shift Saturday, as unbeaten turf performer Rock Your World seamlessly transferred his game to dirt in the $752,000 Santa Anita Derby (G1).

Robert B. Lewis S. (G3) winner and San Felipe S. (G2) runner-up Medina Spirit will be the horse to beat in Saturday’s $750,000 Santa Anita Derby.

The Lewis shapes up as arguably the trickier race to handicap, with a well-matched field. But the Holy Bull might have a greater impact over the long haul, by producing a major Derby contender.
