Lady At Peace won for new owners Jon and Sarah Kelly and new trainer Ed Gregson on Monday in the $150,000 San Gorgonio Handicap at Santa Anita. In a field reduced to five after the scratch of Keeper Hill, Lady At Peace, the 5-1 third choice, crawled through 49 1/5 and 1:12 3/5 fractions under jockey Garrett Gomez and had more than enough left in the final furlongs to beat 1-2 favorite Spanish Fern by 1 1/2 lengths. In winning for the fifth time in 12 starts, the 4-year-old Lord At War filly covered the 1 1/8 miles on turf in 1:48 3/5. . . . Jockey Brice Blanc was off his mounts after injuring his right hand in a spill Sunday.
