Cincinnati ? Eric Gagne was stunned, then enraged.

Ejected for hitting Adam Dunn in the ninth inning of a close game Thursday, the Dodgers closer lost his cool, kicked his glove and threw his cap. Two hours later, Los Angeles was seething over a loss.

Dodgers pitcher Eric Gagne, second from right, is restrained by teammate Chad Kreuter, right, and manager Jim Tracy as he argues with umpire Dan Iassogna. Gagne was thrown out of the Dodgers' loss to Cincinnati on Thursday for hitting the Reds' Adam Dunn with a pitch.

Gagne’s ejection opened the way for Cincinnati’s four-run comeback and Ken Griffey Jr. hit a two-run homer in the 13th for a 6-4 victory.

“I don’t know what to say, really, except that was the grossest error in judgment in quite possibly the history of the game,” said Dodgers manager Jim Tracy, who also was ejected by plate umpire Dan Iassogna.

Until the ejection, there was little drama on a searing afternoon.

Odalis Perez allowed only two hits through seven innings, and Gagne was three outs from finishing a 4-0 win. He yielded the Aaron Boone’s two-run homer, ending the shutout and setting the stage for a 33-minute half-inning.

The next pitch was a fastball that glanced off the back of Dunn’s right arm. Iassogna, who had not given any warnings during the game, immediately pulled off his mask and ejected Gagne. Gagne vainly argued that he would never purposely hit Dunn and bring the tying run to the plate.

Rockies 3, Pirates 0

Pittsburgh Jason Jennings held Pittsburgh hitless for 62/3 innings, the longest such stretch in Colorado history, and the Rockies salvaged the final game of the three-game series. Jennings’ best effort of his so-far excellent rookie season he is 11-5 ended the Rockies’ season-long eight-game winning streak.

Expos 2, D’backs 1

Montreal Vladimir Guerrero hit his second game-ending homer against Arizona this series, connecting with one out in the ninth inning off Curt Schilling.

Astros 3, Mets 1

New York Roy Oswalt kept his cool on a steamy evening, and Houston beat New York for its sixth victory in seven games. After the teams swapped lopsided victories the previous two days, Oswalt (12-6) and Pedro Astacio (10-4) put the emphasis back on pitching.

Braves 4, Brewers 0

Atlanta Greg Maddux pitched six innings for his 268th career win, tying Hall of Famer Jim Palmer for 30th most ever, as Atlanta beat Milwaukee to sweep the three-game series. Maddux (11-3) allowed five hits and lowered his ERA to 2.45.

Marlins 4, Cardinals 0

Miami A.J. Burnett pitched a four-hitter for his major league-leading fourth shutout as Florida beat St. Louis. Burnett (11-7) struck out seven, walked three and tied his career high for wins in a season, set last year. The Cardinals’ lone highlight was a triple play in the sixth inning. It was their first triple play in more than nine years. They caught the Marlins running on a line drive to right field.

Phillies 2, Giants 1

Philadelphia Randy Wolf pitched seven strong innings and Philadelphia scored two runs on a pair of fielder’s choices in the seventh inning to beat San Francisco. Barry Bonds was out of the Giants’ lineup, but pinch-hit in the ninth inning. After missing 10 starts due to a strained right hamstring, Bonds went 3-for-4 with a homer Wednesday night, but appeared to aggravate the injury making a shoestring catch.

Cubs 8, Padres 7

Chicago Alex Gonzalez hit a two-run, two-out double off Trevor Hoffman in the ninth inning Thursday, rallying Chicago past San Diego. Hoffman (1-3) was one out from tying Rollie Fingers for sixth on the career saves list at 341.
