Glass House, a 4-year-old filly trained by William Boniface and ridden by Donald Miller, went around pace-setting Kismet and came away with a length triumph in the Lady Baltimore Handicap at Bowie yesterday.

Fairy Tooth finished third behind Kismet. Boniface and Miller had teamed to win the Preakness with Deputed Testamony. Miller increased his lead over the local riders in stakes victories to 10, while Boniface was registering his sixth added-money victory this year, the second with Glass House.

Kismet was first out of the gate, followed by As Not As and the eventual winner. Jockey Paul Nicol let out a notch on Kismet turning for home and appeared ready to draw away. But Miller had Glass House in high gear and the daughter of Halo responded with a strong run that resulted in a 1:45 1/5 clocking for the 1 1/16 miles.

Boniface, who has replaced Miller on Deputed Testamony with his stable rider, Herb McCauley, in the upcoming summer and fall classics, said, "She (Kismet) goes next in the Matchmaker at Atlantic City (Aug. 6)."

The victory for Glass House was her ninth in 17 career starts. The $21,515 winner's share of the purse brought her earnings over $140,000. The bay is owned by Henry T. Waring of Leonardtown, Md., who said, "We purchased Glass House in a package deal as a suckling."

Glass House paid $7.80 and topped an exacta worth $146.20 to those in the crowd of 9,489 who wagered on the 3-6 combination.
