(AP) - The Kentucky Derby is Saturday at Churchill Downs. Here are five things you should know: Trainer Todd Pletcher will saddle a record-tying five horses - Verrazano, Revolutionary, Palace Malice, Overanalyze and Charming Kitten. He first tried it in 2007, when his best finish was sixth. His only win came in 2010 when he entered four and won with Super Saver. Rosie Napravnik rides long shot Mylute in her attempt to become the first female jockey to win the Derby. She's the sixth woman to try, and she had the best finish in 2011 when Pants On Fire was ninth. Kevin Krigger, a 29-year-old jockey from the U.S. Virgin Islands, will ride Goldencents in a bid to become the first black jockey to win since 1902. That's when Jimmy Winkfield won for the second time. Goldencents is co-owned by Louisville basketball coach Rick Pitino and trained by Doug O'Neill, who won last year's Derby with I'll Have Another. Trainer Shug McCaughey is in the Hall of Fame, but his resume is missing a Derby win. He's 0 for 6 in the big race. He will saddle Orb, the early 7-2 favorite. His best finish was second with Easy Goer in 1989. Trainer D. Wayne Lukas and jockey Gary Stevens own a combined seven Derby wins. At 77, Lukas could become the oldest trainer to win with either Oxbow or Will Take Charge. At 50, Stevens is back in the saddle after ending a seven-year retirement earlier this year.
