Todd Cruz hit two homers and Eddie Murray's two RBI included the game winner as the Baltimore Orioles defeated the Hiroshima Toyo Carp, 5-3, yesterday in the second game of the Orioles' tour of Japan.

Cruz, who hit just three homers in the American League season, had bases-empty shots in the seventh and ninth innings before 45,000 in Tokyo.

The Orioles had lost Saturday, 1-0, to the Carp, the 1984 Japan Series winners and Baltimore's opposition for the first five of 15 games in Japan. Other games will be against the Yomiuri Giants and Japanese all-star teams.

Murray tied the game at 1 with a single in the fourth inning. The Carp moved ahead, 3-2, but the Orioles got two in the eighth as Cal Ripken Jr. and Murray hit RBI singles. Storm Davis allowed one run in five innings. Mark Brown, Tom Underwood, Nate Snell and Sammy Stewart relieved. Snell relieved with a run in, the bases full and none out in the seventh. He put down the rally with a force at home, a run-scoring out in which he threw out a batter who lined the ball off Snell's thumb (it then caromed off his face) and a strikeout . . .

A crowd of 55,000 that included Fidel Castro saw Cuba beat the United States, 10-1, in Havana to regain the World Amateur Baseball Championship. Jim McCollum's fourth-inning RBI was the only highlight for the U.S. team.
