Solar Splendor remained undefeated in three career turf starts when he went wire to wire for a 2 1/4-length victory in the $94,000 Lexington Stakes for 3-year-olds yesterday at Belmont Park in Elmont, N.Y.

"I couldn't ask for a better trip," winning rider Eddie Maple said.

The gelded son of Majestic Light-Sultry Sun ran 1 1/4 miles on the firm course in 2:01 4/5 to finish comfortably ahead of Rouse The Louse. Apple Current was another head back.

Solar Splendor earned $56,640 and, coupled with Libor, returned $6.60.

"He was in control," trainer Pat Kelly said. "For being lightly raced and having a lack of seasoning, he is a quality colt."

Pimlico: In Baltimore, long shot Brick Rider, ridden by Michael Hunter, overtook Sir Sprite in the final stride for a nose victory in the $19,500 feature race.

Brick Rider, ridden by Michael Hunter, ran the six furlongs in 1:10 4/5 and returned $27.20. Ridge Escape finished third.

A furlong past the finish line, Towering Star, who finished last in the field of six, unseated Joe Rocco, Pimlico's leading jockey with eight winners. Rocco complained of a headache and was transported to nearby Sinai Hospital.

A late scratch in the fifth race produced an unusual double-triple payoff. Decisive Incision was scratched at the gate and, since there was no double-triple carryover, the 42 live tickets paid $169.80 each. . . .

Safely Kept, North America's 1989 sprint champion who is undefeated in five starts this year, heads a list of 36 nominations for the inaugural running of the $350,000 Frank J. De Francis Memorial Dash on Aug. 18.
