Light-hitting shortstop Ron Washington hit the first pitch of the 13th inning into the left field screen yesterday in Boston for his first homer of the season, lifting the Minnesota Twins to a 4-3 victory over the Red Sox.

Washington, who entered the game batting .184, hit the first delivery of Luis Aponte (3-2), who relieved Bob Stanley, who had worked 10 innings. Washington's homer, his second RBI of the season, made a winner of Ron Davis (2-1), the fourth Minnesota pitcher.

"I've been struggling, but maybe today will be the stepping stone to get me going," said Washington.

Minnesota, after taking a 2-0 lead in the first, tied the score at 3-3 in the sixth inning when Tom Brunansky led off with a home run. It was the fourth homer of the season for the struggling Brunansky and second in three days.

The Red Sox took a 3-2 lead in the fifth on a leadoff homer by Jim Rice, his second of the game. Rice also homered in the first after a single by Jerry Remy to tie the score at 2-2. Rice's first-inning home run was his first since May 7 and the first Red Sox homer in Fenway Park since May 9.

The victory boosted Minnesota's record to 18-23. It didn't win its 18th game last year until June 26.
