Who challenges umps best? MLB rule change makes playoff debut

The MLB rule change regarding umpire challenges is making its playoff debut. This implementation has led to the creation of accountability meetings and has forced managers to take players offline. Additionally, some managers have had to motivate their players more aggressively, specifically instructing them to tap their helmets more frequently. These adjustments reflect the operational shifts occurring within the league as teams adapt to the new regulations during the high-stakes environment of the postseason games.
