From intense position battles to emerging prospects, the landscape of Major League Baseball is taking shape. This article highlights noteworthy predictions for each team heading into Opening Day.
Arizona Diamondbacks
The Diamondbacks are eyeing a pivotal spring training as their rosters become more defined. With a projected lineup featuring Geraldo Perdomo at shortstop and Ketel Marte as a key second baseman, there’s a notable competition brewing. Former top prospect Jordan Lawlar looks to seize an everyday role in the outfield by adapting to center field, all while navigating competition from Ryan Waldschmidt.

This spring, Max Muncy has emerged as a frontrunner for the starting role at third base after his successful performance last year, especially with Zack Gelof sidelined. The Athletics will also be keeping a close eye on newcomer Shea Langeliers at catcher as he integrates into the lineup.
Atlanta Braves
The Braves' roster decisions will be influenced by the injury of Ha-Seong Kim, who is recovering from a torn finger tendon. His absence opens the door for Mauricio Dubón to step into a prominent role, showcasing a blend of experience and fresh opportunity for the lineup which includes star players like Ronald Acuña Jr. and Matt Olson.
Baltimore Orioles
