There are 40 names on the website roster, but three of them are not on the active playing roster for spring of 2023, and it mentions that if you check the biography section of each play Hector Alejandro was out for the season with an injury. Freshmen J.J. Hood and Sam Clark are not on the active roster and were redshirted for the season. By the way, both Hood and Clark are currently in the Transfer Portal, so it is very possible they will not be back next September for fall ball. There are times when a player in the Portal doesn't end up leaving.
The following players are on the official 37 man roster, but did not play in any games this spring. Highly unlikely they will travel with the team.
Chris Brown - the only non freshman of this group.
Levi McAllister
Ryan Juliano
Noah Sorenson
Gavin Greger
Ryan VanDeWater
Juliano is already playing summer ball in the Futures League. Nothing unusual about that, I've seen that sort of thing before with players who were redshirted but on the playing roster.
