Doesn’t have the same spin on the 4S fastball, will have to command it better to get similar results.

What is his 4S spin rate? And, do you see a mechanical adjustment/tweak that can get a better spin rate? Is that something that as a reliever could increase where he could just rear back and let it eat?

About 2100, vs 2450 for Bundy.

Although Stewart probably has an extra tick or maybe two.

If teams have figured out how to increase fastball spin other than grip substances (which pretty much everyone already uses), it’s not something that I’m aware of. 

The only spin efficiency numbers that are public are the Statcast “active spin” and that doesn’t distinguish 2S/sinkers from 4S fastballs. But there may be a spin efficiency issue, his active spin is listed as 73.6% and the pitch had only 6-7in of vertical rise (not counting the effect of gravity. Drew Smyly who has similar 4S fastball spin axis and spin rate but 92.7% active spin has 9-10 inches of vertical action.

One fun thing about rooting for a bottom-dweller is every little depth move could have a big impact on how the season goes.

There's still a ton of FA out there that will get MLB deals.  That means that teams will have to get rid of players on their 40 man rosters to sign them.  Given our waiver claim position, I expect we'll be in on more pitchers that have options and can go multi innings.
