In reply to: Arguable. In '68 Gibson had a stretch of 261 batters posted by Jellyfinger
Which adjusts for ballpark and league. Gibson had an ERA+ of 258 in 1968, while Pedro's was 291 in 2000,best in the modern era.
Look at the two guys this year. Obviously only a third of a season, but still impressive.
And the Yankees took care of Bieber in the playoffs, just like Pedro
