Ehen it comes to pitcher reinventing themselves, the best success story - and one no one has mentioned - is former Sox SP Frank Tanana. Some of you might remember him. (His Sox tenure was rather nondescript, however.)
Tanana came up at 19 pitching for the Angels alongside Nolan Ryan, and threw nearly as hard. But by age 25, completely ruined his arm.
He came back immediately throwing a huge variety of curveballs, and while he wasn’t the elite pitcher prior to his injury, managed to pitch in MLB until he was 39 years old.
If Sale has to reinvent himself, it can be done quickly. And it can be very successful...
