The Major League Baseball season showcases the raw talent and skill of its players, particularly the starting pitchers. Within each team's rotation, every franchise has an ace—the most reliable arm that they depend on in critical moments. This year, the definition of an ace for this ranking transcends merely being the Opening Day starter or the highest-paid pitcher. Instead, it reflects who has performed the best throughout the season, especially when the stakes are highest.
