With a starting rotation which has lately had trouble making it past the third inning, the Baltimore Orioles got some timely help from Mother Nature last night in Baltimore. Heavy rain from the edges of Hurricane Dennis came on strong enough, and for long enough, for the game to be called after six innings, saving the day for their weary bullpen, and saving the game for the Orioles, who held on to win the opener of their four-game series against the Boston Red Sox, 3 -1. Eli Marrero and Melvin Mora provided solo home runs, and a key fifth-inning, inning-ending pick-off throw by catcher Sal Fasano ended a mounting rally by the visiting AL East Division rivals. Still suffering from key injuries, and still reeling from losing 11 of their last 13 games, the Orioles were not oblivious to the bonus the rain provided: "We needed a break," Baltimore manager Lee Mazzilli said after the game. "It's good to get a win like this."
