All of them pitched over 4500 innings.

I wonder what their pitch counts were in all those complete games (in parentheses).
For the younger generation a complete game is when the starting pitcher and the closer have the same name.
The highest active pitcher on the list
Andy Pettitte at 3268 innings
and the second highest
Mark Buehrle at 2851 innings

Even Tommy John pitched 4710 innings.
It does make you wonder about the current crop of pitchers and the pampered development process.
We seem to be headed for the day when there will be no pitchers qualified statistically for Cooperstown and with the PED thing perhaps no batters either.
And to make matters worse, with the impending advent of instant replay and challenges, we probably will not have any umpires that qualify either.
