Theater R.N., making her stakes debut for Hall of Fame trainer Bobby Frankel, came storming home on the outside to beat stablemate Lots of Hope by a half-length and win the grade II, $150,000 Las Palmas Handicap for fillies and mares on closing day at Oak Tree at Santa Anita Park. Good Student, the 2-1 favorite ridden by Mike Smith, took the lead at the half-mile pole and pulled well clear of the field in the 1 1/8-mile Las Palmas. Lots of Hope made a move at the top of the stretch and started to pull away but a huge finish by Theater R.N. and jockey Rene Douglas gave the 4-year-old daughter of Theatrical the win on a firm turf course in 1:47.81. "I knew my filly would give me a good kick at the end," said Douglas, who won three races on the day. "I timed it perfect and I knew I was going to get up." It was the 43rd career Oak Tree stakes win for Frankel, who is second on the all-time list behind Charles Whittingham's 68. The winner carried 114 pounds and paid $13.80, $7.60 and $4.40. Lots of Hope carried 117 and paid $6 and $3.20. Good Student carried 114 and paid $2.80. It was the fourth win in five lifetime starts for Theater R.N., a Kentucky-bred filly owned by Mark Dedomenico of Seattle who races as the Pegasus Thoroughbred Training Center, LLC. Theater R.N. nearly doubled her lifetime bankroll, earning $90,000 for a career total of $181,800. Also Sunday, Mike Mitchell captured the Oak Tree training title and Corey Nakatani finished at the top of the jockey standings. Mitchell won 13 races from 30 starts, for a remarkable 43 percent win rate. Nakatani won 21 races. Victor Espinoza and Tyler Baze finished tied for second with 19 wins apiece. In the closing-day Pick 6, a single winning ticket paid $191,291.
