Let us look at this statistically and as fairly as we can. CC Sabathia has less innings pitched, 135, then Kuroda's 143.2 because of a groin injury but that is not enough of a gap to really worry me about sample size.
Kuroda 50.1 %
I know that this is probably irrelevant but I really love to go to fangraphs and look all the way at the bottom at look at the VALUE of a player, dollar wise, and compare it to their real salaries.
Actual Salary - $23 Million
VALUE - $14.5 Million
Actual Salary - $10 Million
VALUE - $12.3 Million
While Sabathia is more "VALUABLE" then Kuroda, and is better or close to Kuroda in all the stats posted above he is also making $13 million more then Kuroda. Do not get me wrong I love Sabathia and would not want anyone else on the team starting game 1 of the season and game 1 of the playoffs but where Michael Pineda was supposed to be the #2 starter we have been looking for the last couple of years and wasn't I think we already have him and do not realize it... Hiroki Kuroda.
Plus there are worse things that could happen then a guy like Kuroda having better or comparable stats to our ace CC Sabathia....
