The Atlanta Braves managed five consecutive two-out RBI singles in the third inning, including one by pitcher Bob Walk, as they broke a four-game losing streak with a 7-3 victory over the San Francisco Giants last night in Atlanta.

Rafael Ramirez started the five-run rally with a single. He stole second and stopped at third on Terry Harper's single. After Dale Murphy struck out for the second out, run-scoring singles followed by Bob Horner, Chris Chambliss, Biff Pocoroba, Jerry Royster and Walk.

Walk (10-7) faced two batters in the eighth before relieved by Steve Bedrosian, who earned his seventh save. Walk gave up eight hits, walked six and struck out two.

Loser Fred Breining (5-4) left in the third after yielding five of Atlanta's seven hits in that inning.

It was the 31st comeback victory this season for Atlanta, which had been swept in a four-game series by Los Angeles over the weekend, one shy of the team's longest losing streak of the season, in April.

The victory increased Atlanta's National League West lead to seven games over San Diego and 7 1/2 over Los Angeles, both losers last night.
