While there's some interesting stuff in that Stark article, there's some eye-roll stuff like
Then again, he also didn't play baseball in an age when we were obsessed with walks, or on-base-percentage, or wRC+. So maybe, if someone like Tony Gwynn arrived in the big leagues tomorrow, we wouldn't value him quite the way we appreciated him in his own time.
Who wouldn't appreciate Gwynn overall now?
• Gwynn got hits off Tom Seaver, Nolan Ryan, Steve Carlton and Phil Niekro -- four men who won a combined 1,282 games.
That's cool in all, but I'd imagine there are lesser hitters who might have done the same, and I'm not sure it's statistically significant. I can't find any site that compiles batter versus pitcher stats, but I know Robin Ventura has at least gotten a hit off Nolan Ryan, and I'd imagine one off Randy Johnson, Greg Maddux, and Tom Glavine (1287 wins).
That aside, cool.
edit - apparently it's on BReferrence, and Ventura has hits against Clemens (354), Maddux (355), Johnson (303), and Ryan (324). That's 1336.
Just quickly looking at Steve Carlton's game logs, Jesse Barfield has hits against Steve Carlton, Randy Johnson, Roger Clemens, and Tom Seaver.
I mean, Craig Grebeck has hits off Roger Clemens (354), Mike Mussina (270), Tom Glavine (305), and Nolan Ryan (324) (that's 1253). Bonus points for Pedro Martinez (219).
