I will defer to aba on the New Mexico and Colorado teams.
TCU is the host field, and I think UTA will host some games as well.
The teams I know of are:
Frozen Ropes Titans
Texas Blackhawks Black
DBAT Mustangs Guthrie
Houston Miracles Blue
DBAT Mustangs Carpenter
Albuquerque Baseball Academy
Cherry Creek
and I believe a team from Louisiana (last year it was Bill Hood)
