Corey Kluber tossed 215 innings for the-then Cleveland Indians in 2018. That led all of baseball, as did his two complete games. He posted ~6 WAR according to the publicly-available metrics.
Did he win a third Cy Young award? No, but he finished third in voting and was an All-Star. It was his last great season. The picture isn’t quite as pretty for Kluber after but no one can predict a line-drive that fractures a throwing arm.
To help us better understand Kluber’s dominance before that moment it helps to look at his entire career. I will attempt to do this by sharing a screenshot of a spreadsheet.
