Bill Gullickson pitched seven shutout innings and Dave Parker hit his sixth home run as the Cincinnati Reds ended their longest home losing streak of the century with a 2-0 victory last night over the Atlanta Braves.

Parker's first-inning homer and Tracy Jones' RBI single in the seventh helped end the Reds' nine-game losing streak and 11-game home losing streak. Cincinnati has lost 13 of its last 15 games for a 6-16 mark, the worst in the major leagues.

Parker lined a 2-1 pitch over the right field wall with two out in the first, one of five hits off David Palmer (2-2), who struck out eight and walked three in 6 2/3 innings.

Jones drove in the other run off Palmer with a pinch hit after Bo Diaz doubled.

Gullickson (1-3) stopped the Braves on four hits, with John Franco making a one-hit relief appearance for his third save. Gullickson, winning his first game with the Reds following an offseason trade with Montreal, struck out three and walked two. He also benefited from sloppy base running in the fifth by Claudell Washington.

Washington doubled with two out. Rafael Ramirez beat out an infield hit, but Washington continued around third base and jogged absent-mindedly toward home. He was tagged out after a throw from first baseman Pete Rose to catcher Diaz.

*Cubs 7, Dodgers 6: Leon Durham's leadoff home run in the ninth inning, the 100th homer of his career, gave Chicago a victory over the visiting Dodgers.

The homer, just after Tom Niedenfuer (0-2) had entered, was Durham's fourth this season and the seventh homer of the game as the batters took advantage of a 21-mph wind blowing out.

Reliever Lee Smith (2-2), coming off the 15-day disabled list, earned the victory.

Keith Moreland's two-run homer in the seventh inning gave the Cubs a 6-5 lead but the Dodgers tied it in the eighth when Steve Sax doubled and scored on a single by Mike Marshall. Ryne Sandberg (three hits) had singled before Moreland hit his second homer of the season.

Starter Bob Welch hit a three-run homer and Sax and Mariano Duncan also homered for Los Angeles. Gary Matthews and Shawon Dunston also hit home runs for the Cubs.

Welch's homer was his first hit of the season and the second homer of his career.

*Expos 8, Phillies 0: In Philadelphia, Andy McGaffigan had his first major league shutout in leading Montreal to its fourth straight victory.

Andre Dawson doubled and homered, batted in two runs and scored twice to lead the Expos' 10-hit offense against Steve Carlton and three relievers.

McGaffigan, who beat the Phillies in his only other decision, allowed eight hits, struck out seven and walked four. Carlton (1-5) gave up six runs in five innings.

The Expos, held scoreless on one hit through the first three innings, took a 4-0 lead in the fourth with the help of an error that made three runs unearned.

With one out, Dawson doubled, then scored when second baseman Juan Samuel booted Hubie Brooks' grounder. After Tim Wallach hit a ground-rule double, Andres Galarraga drove in a run with a groundout. Vance Law hit a 2-1 pitch over the right field wall for his third homer.

The Expos made it to 6-0 in the fifth on a two-run homer by Dawson, his seventh.

Montreal's Tim Raines, who has had a hit or walk in all 23 games this season, tripled to extend his hitting streak to 11 games.

*Giants 7, Pirates 2: Two-run homers by Chris Brown and Candy Maldonado backed the seven-hit pitching of Mike Krukow as visiting San Francisco ended Pittsburgh's four-game winning streak.

Krukow (4-2) was touched for both runs and four hits in the first inning. He struck out five and walked three in leading the Giants to their third straight victory.

With the Pirates leading by 2-1 in the third, Will Clark drew a leadoff walk from Rick Reuschel (2-3) before Brown's second homer.

*Padres 3, Cardinals 2: In St. Louis, pinch hitter Jerry Royster hit a two-out double in the ninth inning to drive in the winning run for San Diego.

Marvell Wynne led off the inning with a single off Ken Dayley (0-1). Graig Nettles forced Wynne on a groundout and Bip Roberts ran for Nettles. Royster doubled after Garry Templeton struck out.

Gene Walter (1-0) gained his first major league victory by retiring one batter. Rich Gossage got the final three outs for his fifth save.
