Zimmermann is currently sitting with a record of five wins and zero losses. While the win-loss record is not an accurate representation of a pitcher’s ability, Zimmermann’s win-loss record does speak volumes about his ability to get the win. He is pitching better than any other pitcher in the MLB has ever pitched in his first five starts in April.
There are only three pitchers in this current season who have won their first five starts: Zimmermann, Jake Arrieta, and Chris Sale. Of the three, Zimmermann has pitched in 33 innings, Arrieta has pitched in 36, and Sale in 38.
