Milwaukee Brewers pitcher Jacob Misiorowski, the front-runner for the National League Cy Young Award, suffered his worst outing of the season on Wednesday night, ending a 25-start streak in which he had never conceded more than three earned runs. The stumble has fuelled debate over whether the Brewers, already assured of the postseason's top overall seed, should rest the 24-year-old ahead of October to keep him fresh for a potential championship run.

Facing the Chicago Cubs at Wrigley Field, Misiorowski lasted just four innings, allowing five runs on five hits and four walks while striking out five, extending a mild decline over his past four starts. He has already thrown a career-high workload and could approach 180 innings this year, prompting former Cy Young winner Jake Peavy to argue on MLB Now that Milwaukee should skip him a start or two to have him at his best for the playoffs, given the team's deep lineup and pitching staff make Misiorowski the key to their first World Series title.
