Raul Gonzalez's two-run opposite-field home run in the 10th inning snapped a tie and sparked the Trenton Thunder to a 3-1 win over the Bowie Baysox last night in a Class AA Eastern League game before 6,106 at Prince George's Stadium.

In the ninth inning, Trenton's Israel Contara hit a towering home run over the left field wall to tie the game at one. It was Contara's 17th homer this season.

Trenton (43-18) maintained first place in the Northern Division of the Eastern League. In the Southern Division, Bowie (35-27) fell 2 1/2 games behind first-place Erie, which beat Norwich, 2-1.

Trenton's win spoiled an excellent pitching performance by John Parrish, who held the league's best-hitting team to two hits through five innings. Parrish made his debut for the Baysox after being promoted from Class A Frederick, where he was 2-2. Parrish's counterpart, Trenton starter Ohka Tomokazu, was even better, and held the Baysox to two hits through six innings.

But Bowie came alive in the seventh. Tim DeCinces doubled and stopped at third on Eugene Kingsale's single. After Carlos Casimiro popped out, Cesar Devarez, pinch running for DeCinces, was caught in a rundown and tagged out at third. Howie Clark then singled to score Kingsale from second and give Bowie a 1-0 lead.

Rain delayed the start of the game about an hour, and forced a 15-minute postponement in the fourth inning.
