Matthew Liberatore's recent outing for the St. Louis Cardinals against the Kansas City Royals ended prematurely due to fatigue, leaving his performance in question. The 25-year-old left-hander struggled, giving up seven runs over four-plus innings, marking a season high. His last two starts have been notably poor, with a total of twelve runs allowed. While Liberatore initially earned a rotation spot, this recent trend raises concerns about his stamina and future role with the team.

In his previous outing against the Texas Rangers, he allowed five runs in five innings. The Cardinals, now with mounting pressure, must decide how to manage Liberatore's workload moving forward. His ERA, while respectable at 2.42 since mid-April, may not reflect his current struggles.
