The Mets and Diamondbacks are set for a three-game series starting Tuesday at Citi Field, with key players to watch including Juan Soto, who may be on the verge of a breakout with recent strong performances, and Brandon Nimmo, who has rebounded from a slump. The Mets might call up Brandon Waddell as a sixth starter, while Corbin Burnes shows signs of improvement for the Diamondbacks. Predictions highlight Soto as the potential MVP of the series, David Peterson as the Mets’ best pitcher, and Corbin Carroll as a significant threat to New York.
