In the last few seasons, the New York Yankees starting rotation was not as well as people thought it was. Masahiro Tanaka, the teams imported ace, has been giving up (on average) 4.5-4.9 runs per game, with an adjusted WAR of -0.1, averaging a .500 record over that time span. Luis Severino is still trying to figure himself out. And while CC Sabathia is now retired, he… uh, wasn’t great.
What About Now?
Gerrit Cole is a big upgrade. Like… such an upgrade that we catapult ourselves to the top of the league in terms of starting rotation.
