We usually have some info about where everyone will be playing for the Summer. Updated for 2023. Baseball Announces 2023 Summer League Assignments - Florida Gators
Baseball staff have the info and probably will release it at some point. I've heard Sullivan Bortner, is a big help with that sort of thing.
The best I've found is through Baseball Reference. The 2023 Gators are listed on: 2023 Florida Gators Statistics | Baseball-Reference.com If you click on any player, it'll to their page, which will tell you other team(s) they've played for including summer leagues. I don't know how current or how complete it is, but Florida Summer, Cape Cod, and Northwoods leagues look to be filling in. USA National team is not (and, I believe, does not in general). So far, it looks like a lot of guys aren't playing anywhere else yet.
I saw that Fabian and Tejada were the only ones from UF listed on Cape Cod League rosters. Also Cags is listed on a CC roster as inactive.
Thanks for the link/post. I wonder why out Gator uniforms don't have an American flag on it somewhere. Stanford had an American flag on their uniforms and their helmets.
