Simmering acrimony between a prominent trainer and top jockey erupted into fisticuffs on Sunday at Los Alamitos, where trainer Richard Baltas and jockey Martin Pedroza scuffled briefly before being separated by a security guard.
Baltas emerged from the scrap with a swollen nose after Pedroza struck him in the face with his helmet. Baltas claimed that Pedroza instigated the incident; Pedroza said it was Baltas who started the fight.
