The MLB trade deadline saw over 60 deals, but the most impactful moves may not be the ones that made good teams better. Instead, trades that could determine whether a team makes the playoffs at all carry the highest stakes. The Red Sox acquired three-time All-Star catcher Adley Rutschman from Baltimore, but he arrived on the injured list with wrist inflammation, making his health the key variable for Boston's playoff hopes. The Padres, sitting one game out of a wild card spot, completely overhauled their struggling rotation by acquiring Casey Mize and Robbie Ray, betting their postseason fate on these arms.
