The article ranks the best in baseball for the 2026 season, ranking the Nationals' rotation as the worst by a significant margin. The Nationals signed Miles Mikolas and Zack Littell to replace Mackenzie Gore and Josiah Gray, but Cade Cavalli may be the only long-term piece on the staff. The Rockies added Michael Lorenzen, Jose Quintana and Tomoyuki Sugano to their pitching staff, while the Angels have a strong top of the rotation with José Soriano, Yusei Kikuchi and Reid Detmers, but the back of the staff could be a revolving door due to injuries. The Cardinals have 337 innings to replace after trading Sonny Gray and letting Miles Mikola walk in free agency, much of that workload will fall on young, unproven arms. The Athletics are relying heavily on the up-and-coming duo of Jacob Lopez and Luis Morales. The Braves have signed free agents Anthony Kay and Erick Fedde to fill their gaps. The D-backs ranked 23rd in the majors with a 4.49 ERA last season and return essentially the same core group after re-signing Merrill Kelly and Zac Gallen. The Twins' loss of Pablo López for the season to Tommy John surgery is a major blow for their staff. Despite trading away Edward Cabrera and Ryan Weathers, the Marlins still have a solid collection of arms, including Sandy Alcantara and Eury Pérez.
