Christiana's Heat and Lucky J.H., California-breds who won stakes on the hillside turf course earlier at the Santa Anita meeting, have been retired after sustaining injuries.\nLucky J.H., the winner of 8 of 20 starts and $632,065, recently suffered a suspensory injury, according to trainer Carla Gaines. The injury was detected a few days after Lucky J.H. worked five furlongs in 59 seconds at Santa Anita on March 20. Lucky J.H. was being prepared for a start in Sunday's $125,000 Sensational Star Handicap for statebreds when the injury was diagnosed.\n"He's never had any ligament problems," she said. "He's had some feet problems."\nOwned by breeder John Harris, Lucky J.H. won four stakes, beginning with the Tiznow Stakes and Grade 3 Ack Ack Handicap at Hollywood Park in 2006. Last year, he won the Sensational Star Handicap in April and the Impressive Luck Handicap here in December. Both of those races were over about 6 1/2 furlongs on the hillside turf course at Santa Anita.\nBy Cee's Tizzy, Lucky J.H. made only four starts in 2008, a season plagued by quarter cracks. This year, he made two starts, finishing 12th in the $500,000 Sunshine Millions Turf and fifth in the Crystal Water Handicap.\nChristiana's Heat ended her career as a winner. Shortly after a victory in the Irish O'Brien Stakes on March 15, she was diagnosed with swelling in a leg, trainer Steve Knapp said.\n"She came out of the race with a little filling," he said. "Four days later, we X-rayed it. She'd hurt a sesamoid. It was time to retire her."\nKnapp estimated that Christiana's Heat would have needed at least six months off before resuming training, meaning she would not have started until late this year at the earliest.\nBecause she is 5, the decision was made to retire her. Christiana's Heat won 5 of 24 starts and $332,332. By Unusual Heat, Christiana's Heat is owned by Albert and Kathleen Mattivi. In addition to her victory in the Irish O'Brien for statebred fillies and mares, Christiana's Heat placed in three stakes on the hillside turf course between last October and January.\nKnapp said that Christiana's Heat will be sent to Kentucky and bred to Yes It's True.\nSale goes back to Pleasanton\nThe 2009 Northern California yearling sale, to be held Aug. 11, has been shifted back to the Alameda County Fairgrounds in Pleasanton after being held at Santa Rosa last year.\nThe sale was conducted at Pleasanton from its inauguration in 2004 until 2007, then was shifted to Santa Rosa. Last year, officials with the California Thoroughbred Breeders Association, which operates the sale, said that one of the reasons for the venue shift was a move from temporary stalls at Pleasanton to permanent stalls on the backstretch of the Santa Rosa fair.\nIn a statement on the CTBA's website, the association said that Pleasanton officials will provide "the safest portable stalls available" for this year's sale. The 2009 sale has an entry fee of $300 and a minimum commission of $500. The entry deadline is April 3.\nThe sale had a poor year in 2008, with 104 horses selling for an average of $4,536, a decline of 22 percent from 2007.\nThe Northern California sale has always been geared toward a regional market, with prices that reflect that. In 2006, the sale average $8,192, the highest figure since the one-day event was launched. \nOver the years, the sale has produced such stakes winners as Bai and Bai (who earned $724,983), Sierra Sunset, and Autism Awareness.
