Maybe.
He's got a 4.45 ERA vs BOS compared to his overall career mark of 3.23. That's a pretty big difference, but not quite as dramatic as Sale's career mark of 2.95 compared to 4.44 vs CLE.
Sale's innings sample size vs CLE is more than twice that of Kluber's vs BOS.
And then there's this:
Sale last three starts vs Indians:
5.1 IP/GS ~ 10.6 K/9 ~ 2.6 K/BB ~ 1.83 WHIP ~ 9.39 ERA
Kluber last three starts vs Red Sox:
7.2 IP/GS ~ 10.4 K/9 ~ 4.2 K/BB ~ 0.83 WHIP ~ 1.66 ERA
