N.L. Wednesday’s games

Braves 1, Pirates 0: At Pittsburgh, Russ Ortiz shut out the Pirates for seven innings to win his sixth in a row and Chipper Jones homered for Atlanta’s only run off rookie Oliver Perez, leading the Braves past the Pirates. The game matched two streaking pitchers in Ortiz and Perez, neither of whom had lost since June, and two of baseball’s hottest teams — the Braves have won 21 of 28, the Pirates 21 of 29.

Expos 7, Mets 4: At Montreal, Tony Batista homered and drove in two runs, and Nick Johnson hit a go-ahead RBI double in the fifth in leading the Expos to a win over New York.

Cardinals 11, Reds 10: At Cincinnati, Scott Rolen hit two of the Cardinals’ four homers, repeatedly blunting Cincinnati’s comeback and sending the Reds to their eighth straight loss.

Brewers 6, Cubs 3: At Milwaukee, Chris Capuano pitched effectively into the seventh inning, and Bill Hall and Ben Grieve homered to help the Brewers snap a four-game losing streak with a victory over Chicago.

Marlins 6, Phillies 3: At Miami, Mother Nature and Hee Seop Choi made it another miserable night in Miami for Philadelphia, who endured two rain delays before losing again to Florida. Choi hit a tiebreaking three-run homer in the eighth inning, and Florida extended its winning streak against the Phillies at Pro Player Stadium to 13 games, including six this year.

Astros 6, Diamondbacks 1: At Houston, Roger Clemens struck out eight and allowed one run in seven innings, leading the Astros over reeling Arizona.

Rockies 5, Dodgers 4: At Denver, Aaron Miles hit a tiebreaking single off Guillermo Mota in the eighth inning and Jeromy Burnitz homered in his sixth straight home game to tie a team record, leading Colorado to a victory over Los Angeles.

Padres 9, Giants 4: At San Diego, Sean Burroughs had a two-run single and Ryan Klesko added a two-run double in a five-run sixth inning, and the Padres went on to beat San Francisco.
