Speaking of Bauer, I was looking at SP in the Japanese League for 2023. If you sort by strikeout rate and ignore pitchers who didn't throw 100 innings (so we are only looking at full time starters) the two standouts are:
Bauer, 130.2 IP, 4.19 K/BB, 9.0 K/9, 3.03 RA9
Shota Imanaga, 148 IP, 7.25 K/BB, 10.6 K/9, 2.80 RA9
Imanaga is 30 and getting posted this offseason. Bauer's stats give a nice benchmark - Imanaga might be "better than Bauer".
