Trachsel (12-7) pitched a complete game one-hitter, his second of the season, to earn the victory. In June, he lost the bid to David Eckstein with two outs in sixth against Anaheim. This time, with two outs in the sixth, it was Chin-hui Tsao who broke it up with a double.
It was his second shutout of the season and seventh of his career. He also owns both of the Mets two complete games this year.
New York has now scored ninety-two runs in their last fourteen games after sweeping a four-game series at Shea Stadium for the first time since 1997 against Cincinnati.
The Mets (54-69) didn't waste any time taking a lead against Rockies starter Chin-hui Tsao (2-1). With one out, Jose Reyes singled into right field and extended his hitting streak to a career-high seventeen games. Mike Piazza then slammed a two-run homer, his ninth of the season, over the left field wall.
Colorado (61-66) has now lost nine of their last ten contests.
With Jose Reyes on again with a hit, Jason Phillips added his own two-run home run in the third, his tenth, to extend the margin to 4-0.
New York broke the game open in the bottom of the sixth with four runs. Roger Cedeno opened the scoring with a RBI single to put runners of first and second. Jose Reyes walked to load the bases before Mike Piazza hit a grounder to third, but Garret Atkins threw it away and allowed two runs to score.
Cliff Floyd, playing his last game of the season, capped the inning with a RBI single.
He received a standing ovation during his final at bat in the eighth. Mets manager Art Howe sent him out to left field in the ninth, but replaced him with Raul Gonzalez before the inning started so the crowd could have the opportunity to acknowledge him one last time.
Chin-hui Tsao -- who had seen the Rockies win three of his four major league starts -- lasted just 5 2/3 innings, allowing ten hits and seven runs while walking three and not striking out a batter.
