ARCADIA, Calif. - On the Acorn, who rose from a $40,000 claimer to become a multiple graded stakes winner, has been retired because of a recent injury, according to Jack Disney, a member of the partnership that owns the 8-year-old gelding.\nOn the Acorn was being prepared for a return to racing with trainer Mike Mitchell at Hollywood Park when he was diagnosed with a ligament tear, Disney said in an e-mail.\nOn the Acorn was claimed in November 2006 and won 5 of 10 starts and $581,400 for the Indizguys Stable partnership, which included Disney, a publicist at Santa Anita; his brother, Doug; former Los Angeles Angels baseball manager Buck Rodgers; baseball writer Ross Newhan; former San Francisco 49er Paul Salata; and insurance executive Fred Krueger.\nAfter he was claimed, On the Acorn won the 2007 San Juan Capistrano Handicap at Santa Anita and consecutive runnings of the Jim Murray Handicap at Hollywood Park in 2007 and 2008. The 2008 Jim Murray was On the Acorn's final start. A month later, Mitchell said that On the Acorn had been taking out of training because of swelling in an ankle. At the time, he was a candidate for the Hollywood Gold Cup.\nOn the Acorn won 8 of 32 starts and $743,812 in a career that began in 2004.\nCharming Legacy earns a stakes shot\nCount Charming Legacy as one of the luckiest horses at Santa Anita.\nIn the fall of 2007, she was on her way to the gate for a turf race when she unseated her rider, ran down the course, and crashed into the rail. She needed 32 stitches to close wounds on her chest and a leg caused by the collision.\nIt was the sort of injury that could have killed her, or ended her career. Instead, Charming Legacy was off for more than a year before winning an allowance race here on Jan. 1. Sunday, she makes her stakes debut in the $100,000 Tuzla Stakes for fillies and mares over a mile on turf.\nThe filly is owned by Ellen Zetcher and Debbie McAnally, the wife of trainer Ron McAnally.\n"The way Debbie and I look at it, every race she runs is the gift," Ron McAnally said.\nThe 2007 incident was captured on a patrol camera, but McAnally has never seen the footage. It's something he would prefer not to witness, having spent time at the barn after the accident, watching veterinarians attend to Charming Legacy.\n"All the assistant starters ran down there and got the rail off of her," he said on Sunday, recalling the incident. "If she had a thrashed a little, she would have been history."\nCharming Legacy won the fourth race of her career on Jan. 1. McAnally said she has a chance to win on Sunday against 13 rivals.\n"She is really going good right now," he said.\nTwo good prospects for Hollendorfer\nTrainer Jerry Hollendorfer saddled two winners on Thursday - Tuscan Evening in a maiden race on the hillside turf course and Blue Exit in an optional claimer over 1 1/16 miles on the main track.\nFriday, he was reluctant to guess how much farther those promising horses would progress. "I'm a little more conservative in my thinking," he said.\nIt is easy to find promise with both horses. Tuscan Evening, who won her U.S. debut on Thursday, finished second at 66-1 in the Group 1 Irish 1000 Guineas last year, but was demoted to fourth for causing interference. Now owned by William de Burgh, Tuscan Evening was not challenged on Thursday. She led throughout and won by five lengths.\n"She had run against tough company" last year, Hollendorfer said. "She had worked well; lucky for us she ran well."\nTuscan Evening is expected to make her next start in an allowance race.\nThere may be loftier goals for Blue Exit, though Hollendorfer was non-committal on Friday. Making his third start in this country on Thursday, Blue Exit closed from last in a field of six to win by three lengths.\nBlue Exit was 13th in the Grade 2 Oak Tree Derby on turf last October. He wore blinkers for Thursday's race. Blue Exit was a minor stakes winner on turf in France last year, and could return to that surface.\nHollendorfer has another European import who will start in coming months, the 4-year-old filly Soinlovewithyou, owned by de Burgh. Previously trained by Aidan O'Brien, Soinlovewithyou was a 100-1 pacesetter for a stablemate in the Irish 1000 Guineas, and finished last.\nSoinlovewithyou has joined Hollendorfer's stable at Santa Anita.\n"I don't have a time frame for her" next start, Hollendorfer said.\n* Jockey Aaron Gryder attended the inauguration of President Barack Obama on Tuesday as a guest of California representative Brad Sherman. Gryder was close enough to the podium to get a decent view of the ceremony.\n"We could see him clearly," he said. "It was phenomenal."
