There's been a lot of exciting baseball already just one week into the 2026 MLB season. Rookies are dominating the conversation around the sport as they've had stellar starts to their major league careers. Chase DeLauter and Munetaka Murakami made history by homering in each of their first three major league games, only the third and fourth rookies to ever do so. Kevin McGonigle had a four-hit debut, and JJ Wetherholt hit his first major league home run in his debut. We've also seen bullpen concerns in the early days (especially in Kansas City), an exciting first start on the mound from Shohei Ohtani and a surprising team atop the standings in Miami, and no teams have gone undefeated in the first week of game play. Is your favorite club off to a dominant start -- and more importantly, will it last? Or are you hoping the first week's returns aren't a glimpse of the future?…
