A promising four-game winning streak came to a halt for the New York Mets on Wednesday night, as a rough second inning from starter David Peterson and a quiet night at the plate led to a 7-2 defeat against the Arizona Diamondbacks.

Peterson, who had been sharp in his season debut, couldn't find his rhythm early. After a somewhat unlucky first inning, the Diamondbacks' offense exploded in the second. The key blow was a scorching, bases-clearing double off the bat of Corbin Carroll on a first-pitch curveball, plating three runs and putting the Mets in a deep 5-0 hole. To his credit, Peterson battled back, retiring 11 of the final 12 batters he faced to complete five innings, but the damage was done.

His recent outings highlight a concerning trend; after a stellar first start, Peterson has now surrendered 10 earned runs over his last 9.1 innings of work. A pitcher's ability to reset after a tough inning is crucial, and the Mets will be looking for that bounce-back resilience in his next appearance.

Meanwhile, the Mets' lineup, which had shown life during their winning streak, was stifled by Arizona's Ryne Nelson. Nelson carried a no-hit bid into the fourth inning and largely kept the Mets' hitters off balance. New York finally broke through in the sixth, stringing together three singles—including an RBI knock from Brett Baty—but they could never mount the sustained rally needed to claw back into the game. A late double from Baty in the eighth produced the final run, but it was too little, too late.

For a team with postseason aspirations, consistency is the name of the game. This loss serves as a reminder that in baseball, success requires both a starter who can limit the big inning and an offense that can provide timely support. The Mets will look to salvage the series finale and regain their momentum as they continue their grind through the early season schedule.
