Alejandro Pena pitched a four-hitter last night and the Los Angeles Dodgers won, 3-0, in Philadelphia to extend the Phillies' scoreless streak to 35 innings and their losing streak to four games.

Pena (5-1) struck out eight, walked three and allowed only one runner to reach second in his first major-league complete game. Loser Larry Christenson (1-4) allowed only three hits in seven innings.

"It's the best game I've ever pitched in the major leagues," said Pena. "I pitched some good games in the Dominican League, so I just pretended the Phillies wore the same uniforms as the teams I've faced in the Dominican Republic."

The Dodgers took a 1-0 lead in the fourth when Dusty Baker, breaking out of a slump with two doubles, an RBI and a run scored, hit his first double with one out. He moved to third on Pedro Guerrero's grounder and scored on a wild pitch.

In the sixth, Ken Landreaux singled with two out, stole second and scored on Baker's second double.

The Phillies' only threat came in the third when Bob Dernier walked with two out and stole second. But Pena retired Pete Rose on a fly ball.

The defeat was the Philies' eighth in their last 11 games. They have not hit a homer since May 12 and have only 68 hits in their last 12 games.
