The Mets and Braves begin a three-game series in Atlanta on Tuesday at 7:15 p.m. on SNY, with several key factors to monitor. The Mets’ rotation faces uncertainty with Tylor Megill and Griffin Canning’s recent struggles, while David Peterson and Clay Holmes are needed for stabilization. Meanwhile, the Braves, 13 games behind the Mets, must improve their performance to avoid being sellers at the trade deadline, and players like Matt Olson and Juan Soto could play significant roles in the series.
