My goodness, no he did not. This is an embellishment. This is how misinformation gets spread. And we so often on here just take a narrative and run with it.
Yes, he is known for getting sick. Yes, he made a casual quote when he was moved to the pen about being able to feel more relaxed, That was it. He never said he couldn’t start and would “get so worked up before a start that I’d make myself sick.” He never made any such quote as it relates to his pitching role.
If he did,, post the link and the quote and I’d be happy to stand corrected like I do any time I make a mistake. Otherwise, this is inaccurate. The man had an ERA under 3 as a starter and we are acting like he was such a mess that he can’t start. He can. No, I am not saying he should take Gasser’s next start, but I am saying if fully ramped up, yes, I believe he’d be a better starter than Gasser.
