It was a game of errors, pickoffs and bloopers until Brad Tyler struck a blow everyone understood.
Both teams had four errors, and two London runners were picked off and another was cut down at the plate in the middle innings.
Tyler was batting .176 with no homers in July after being chosenthe Orioles' minor league player of the month for June.
He connected after a infield single by Jason Alstead with one out in the seventh, giving the victory to Brian DuBois, who left with a 3-1 lead.
With Jim Dedrick pitching, Tigers cut the lead to 3-2, but Dedrick struck out the side in the eighth and pitched a scoreless ninth after Tyler's homer.
The last time DuBois and Lima hooked up in Canada July 21, the Tigers won a wild, 14-13 game, and neither was involved in the decision. Seven errors were committed behind DuBois in 2 1/3 innings, and Lima gave up 12 hits and nine runs in six-plus innings. London won on a single by Robert Higginson off Dave Paveloff in the ninth.
The rematch was almost as sloppy with both teams being charged with three errors by the fifth inning.
Bowie took a 1-0 lead in the bottom of the second against Lima, who was making his sixth start in the series (0-2, 6.39 ERA against the Baysox entering the game).
Jim Wawruck singled with two out and scored when left fielder Ted Williams misjudged Kyle Washington's line drive for a two-base error.
After getting runners to third in the first two innings without scoring, the Tigers matched the Bowie run in the fourth.
Rudy Pemberton hit a chopper up the middle that Tyler tried to field and throw in one motion. He threw wildly to first, and Pemberton reached second on the infield hit and error. Joe Perona then singled to left, and Pemberton continued home when Wawruck overran the ball.
Bowie regained the lead in the bottom half with one out on singles by Stanton Cameron and Gregg Zaun and Wawruck's fielder choice.
Cameron scored when Zaun and London second baseman Shannon Penn collided at the bag as Penn tried to pivot for a double play. The throw to first went awry, and Wawruck reached second.
