ARCADIA, Calif. - Richard Mandella tightened his grip on the winter handicap division Saturday at Santa Anita, where he won his third stakes of the meet - the Grade 2 for 4-year-olds. Minister Eric ($16) won the mile and a sixteenth race by a half-length over 2-1 favorite Mass Media; longshot Skipaslew finished three lengths back in third; Imperialism was compromised by the speed bias and rallied to fourth.
