J. Paul Reddam's 5-year-old Grade 1 winner Square Eddie, who came out of retirement to run three times this winter for trainer Doug O'Neill but then returned to stud duty at California's Vessels Stallion Farm following a ninth-place finish in the G1 Frank E. Kilroe Mile Stakes on the Santa Anita turf, is back in training at Del Mar. The son of Smart Strike breezed three furlongs Sunday over the Polytrack in :37.60.
