After Johnson, it is Mussina at 243, Boomer at 235, Moyer at 224, Schilling at 213, Rogers at 210, Pedro at 206, Smoltz at 203 (with 154 saves).
Then comes Petite at 192.

I don't think any of them will get it. Perhaps Mussina although he would need to go 4 more years at 15 wins/year and he is in his 17th year.
I would have liked to see Johnson make it, but I guess there was only so much torque his body could take.
