Actually this is demonstrably false. If he's a non-closer reliever, he will make less than a mediocre starter. Tommy Milone just got $2.8 mil and now $4.5 mil in his first two go-arounds in arbitration, and he's actually been optioned to the AAA each of the last 2 seasons too. A non-closer reliever, even a good one, will likely only get half that. And for May, that assumes he stays healthy the next two years too). And in the meantime, as a reliever May has almost zero leverage to get a financial guarantee in advance. Consider Kyle Gibson, who after 2.5 years of decent starting pitching was #1 on Jeremy's "Ten to Extend" list, looking at an estimated potential guarantee of ~$30 mil already. Gibson could probably go to the team and guarantee himself $20 million today, with a million dollar signing bonus up front, and be completely set for generations no matter what happens to his pitching arm tomorrow. Next winter, May will have an identical amount of service time to Gibson presently, but with much of it spent in the bullpen, he will have almost zero leverage to get such a guarantee. And like I said in a previous post, this isn't an argument that the Twins should be concerned about May's bank account. It's just a fact that May will earn less and have less security in a relief role, especially early in his career. If you want to bring the team argument into it, consider that it is a poor use of resources given the market. Good relievers can absolutely make notably less than mediocre starters. Darren O'Day has had one of the most effective four year runs of relief pitching ever, and got $31 million this winter, about 60% of the guarantee that Ricky Nolasco got two years ago. After his Detroit deal expires, Mike Pelfrey will have received almost as much as O'Day ($27 over four years). Even a more "elite" setup arm in Andrew Miller, signed to close in New York, only fetched a $36 mil guarantee. These are just a few of the examples that demonstrate how relievers have less market value than starters, calling into serious question the Twins strategy of making big FA investments in mid-tier starters, generally refusing to make any investments in adding outside relief help, and in fact converting promising cheap internal starting talent to relief roles instead.
