Should baseball teams use an opener to improve their starting pitchers' performance?
The Cleveland Guardians have implemented an opener strategy for pitcher Joey Cantillo to curb high walk rates. This tactical adjustment has resulted in two consecutive scoreless outings for the pitcher.
Why it matters
The change was designed to foster a reliever-like mindset, encouraging Cantillo to attack the strike zone more aggressively. By shifting his entry point, the team aims to overcome previous command struggles.
Cantillo recorded 13 strikeouts and two walks over 10 innings with an opener, a marked improvement from his 4.44 ERA over the previous five-start stretch. In his appearance against the Athletics, he allowed only three baserunners and struck out five.

Season Trajectory
The Guardians' use of the opener reflects a broader trend of teams manipulating pitching roles to maximize efficiency as the regular season draws to a close. This strategic shift aims to solidify the pitching staff's performance ahead of the final playoff push.
