BOSTON, SEPT. 22 -- John Abe scored the go-ahead goal in the fifth round of penalty kicks and goalkeeper Steve Powers followed with a diving save to give the Maryland Bays a 2-1 victory over the San Francisco Bay Blackhawks tonight in the American Professional Soccer League championship game at Boston University's Nickerson Field.

Played before 4,881 spectators in a driving rainstorm, the Bays, champions of the American Soccer League, found themselves in the penalty-kick situation after playing to a 1-1 tie through regulation and 30 minutes of overtime.

After each side scored on three of its first four attempts, Abe sent a high shot into the upper right corner to put the Bays ahead. The Blackhawks' Steve Petuskey directed his shot toward the lower left corner, but Powers made a diving save to end it.

Maryland (20-5) will play the Canadian Soccer League-champion Vancouver 86ers Wednesday in Burnaby, British Columbia.

The Bays took a 1-0 lead in the 74th minute on a goal by reserve Scott Cook, who had entered the game 12 minutes earlier. Chris Reif avoided two defenders and sent a centering pass that Cook, sliding forward, pushed past goalie Mark Dougherty.

The Blackhawks tied it with about eight minutes left on a sensational goal by former Howard University All-American Peter Isaacs. Four minutes after entering as a reserve, Isaacs lifted a 15-yard shot from the left side over goalie Steve Powers and into the upper right corner of the net.

The Bays nearly went ahead with 15 minutes left in the first half. Off an indirect kick just outside the penalty area, Rob Ryerson sent a 20-yard shot off the crossbar. Abe's 16-yard rebound shot sailed high.
