The dazzling 3-year-old filly Magnificience will be sidelined until next year because a chip was discovered in her left front ankle that requires minor surgery.
Magnificience burst to prominence with a breathtaking debut March 11 at Santa Anita, and followed with a five-length win April 1 in the Grade 3 Santa Paula Stakes. But soon after she won the 6 1/2-furlong Santa Paula with a 109 Beyer Speed Figure - highest of the year by a 3-year-old of either gender - Magnificience developed heat in an ankle.
