Leaping Plum, the 13-year-old who made 10 consecutive starts in the four-furlong Grasmick Handicap at Fonner Park and won the race eight times, has been retired after a fourth-place finish in this year's Grasmick. Leaping Plum will be turned out at a farm near Brookings, S.D. . . . Spritely Walker staked his claim to the title of the best Louisiana-bred in training Friday night, when he drove to a three-quarter length win over a game Zarb's Luck in the $50,000 Bayou State at Delta Downs. The victory was the fourth in a row for Spritely Walker.
