Lower the IP all the way to 20 to eliminate survivor bias and we can add more names (all 94+)...
Waldis Joaquin
Luis Garcia
Blake Treinen
Evan Marshall
Some of these guys are in the majors, pitching right now, with the same or very similar skillset to Sanchez'. Blake Treinen's repertoire in particular is strikingly similar.
If you were looking only at qualified starters, which you probably were, then that's a list that Sanchez himself wouldn't qualify for. Further, he barely averaged 94 as a SP (I think), so he would be extremely unlikely to have a career where he sits over 94mph. If he's lucky enough to start for the next few years then you're probably looking at an average velo a lot lower than his career to date. Heck a full season in the rotation right now probably has the effect of dropping his average velo way down.
You also forgot 2005 AJ Burnett, otherwise known as Sanchez' light at the end of the tunnel, on your single season qualified SP list.
