Fernando Valenzuela pitched a five-hitter for his fifth straight victory and Steve Yeager and Mike Marshall hit back-to-back homers yesterday in Cincinnati to lead the Los Angeles Dodgers to a 5-1 victory over the Reds.

Valenzuela, who struck out six and walked three in the game played in 85-degree heat, improved his record to 8-2 en route to his sixth complete game. "In a way that helped me to stay loose," Valenzuela said about the heat.

Joe Price (4-4) struck out a career-high nine batters over seven innings but surrendered seven hits and all five Los Angeles runs.

The Dodgers scored in the second when Yeager walked, raced to third on a single to left by Marshall and came home on a single to right by Ron Roenicke.

Los Angeles made it 3-0 in the seventh when Yeager and Marshall homered. Yeager hit a pitch over the left field wall for his 10th home run of the year and Marshall's fourth of the season went to right.

"It's been a while since I've hit a home run and contributed," said Marshall, batting .222 prior to the game. "Both hits today helped to get some runs. That's what it's all about."

Valenzuela's bid for his fifth shutout was spoiled in the seventh when Cesar Cedeno homered.
