What the hell?
I’ve always thought that Verlander was excellent pitcher, because he is an excellent pitcher. I did not undertake this exercise to demonstrate that Greinke is better than Verlander. In fact, the main purpose of the exercise was to find a pitcher whose numbers were close enough to Greinke’s to be comparable, but who played for a team that provided more run support.
If Verlander’s numbers had been dramatically better or dramatically worse than Greinke’s, i would have kept looking until i found someone closer. The main thing that surprised me was that i happened to find someone close on the first try, and that Greinke and Verlander’s numbers were so close in just about every single area.
The reason i made the comparison was to point out how silly it is to make an evaluation of Greinke’s pitching ability based on his W-L record, which is what you did back in post #229. And i think the figures demonstrate quite clearly that, despite having vastly different winning percentages, Greinke and Verlander are pitchers with reasonably similar career performances.
Right. So why post his W-L record as a reason to be cautious about him?
Actually, you don’t really need to see that at all. The numbers i gave in my previous post should make it quite clear that Greinke has had less run support.
We have two pitchers who have started an almost identical number of games; they’ve given up hits and walks at a similar rate; they’ve given up runs at a very similar rate; and yet one has a dramatically better winning percentage than the other. The obvious conclusion here, based on simple deduction, is that run support has been the main difference.
But, in case you don’t believe that conclusion, i rolled out my mad OpenOffice Calc skillz in order to find out how many runs the Royals scored in Greinke’s 156 starts, and how many the Tigers scored in Verlander’s 152 starts. Here are the numbers:
Greinke:
Starts: 156
Total runs scored by Royals: 616
Runs scored per game: 3.95
Verlander:
Starts:152
Total runs scored by Tigers: 776
Runs scored per game: 5.11
That seems like a reasonably significant difference in run support to me.
Or, to put it a different way:
Greinke’s run support exceeded his ERA by 0.24 runs per game. Verlander’s run support exceeded his ERA by 1.21 runs per game. Who’s likely to have the most wins, in that scenario?
