NEW YORK (AP) -- Catcher Kevin Plawecki made an impressive big league debut, contributing with his bat and glove as the banged-up New York Mets won their ninth straight game by beating the Atlanta Braves 7-1 Tuesday night.The Mets extended their longest winning streak since a 10-game run in 2008. The team record is 11 in row, last done in 1990.Curtis Granderson drove in four runs and Jonathon Niese (2-0) pitched shutout ball into the seventh inning, helping the Mets stretch the best home start in club history to 8-0 at Citi Field. A highly regarded prospect, Plawecki got two hits, scored twice and threw out a runner trying to advance on a ball in the dirt.Plawecki was promoted from Triple-A earlier in the day to replace catcher Travis d'Arnaud, out for at least three weeks after breaking a finger when he was hit by a pitch Sunday. The Mets lost reliever Jerry Blevins to a broken forearm in that same game, and are still minus injured third baseman David Wright.D'Arnaud took Plawecki out for dinner during Monday's off-day, telling the 24-year-old minor leaguer that he was ready for the majors. Plawecki, drafted by the Mets in 2012 with a compensation pick they got for losing Jose Reyes to free agency, did more than fine in front of a rooting section that included his parents and fiance.The Braves, meanwhile, hurt themselves. They'd made only one error in their first 12 games before committing two - second baseman Phil Gosselin fumbled a potential double-play grounder by Niese, keying a four-run burst in the fifth inning.Niese blanked the Braves until his 100th pitch, which Cameron Maybin hit for a two-out home run in the seventh. Umpires originally held Maybin at second base, then let him trot home after a replay review.Mets reliever Alex Torres ended the seventh with a 5-1 lead by striking out Freddie Freeman with two runners on, the third time the Atlanta cleanup man fanned.Niese gave up four hits, struck out five and walked four.Trevor Cahill (0-2) was chased in the fifth. He's lost six straight decisions dating to last season with Arizona.Plawecki grounded a single to left field for his first hit and fueled the big fifth. He later scored on Granderson's two-run single.In the sixth, Plawecki pounced on a pitch in the dirt that bounced away and threw out Andrelton Simmons at second. Plawecki singled again in the eighth and scored on a double by Granderson.
