I've found these in the database, the city is after the hyphen:
108937 Old Panther Field - Duncanville (TX)
108903 Central Catholic Stadium - San Antonio (TX)
72006032 Don Thomas Stadium - Reading (PA)
72002741 Union College Field - I think it is: Schenectady (NY) see 42.820, -73.936
(known as "College Park")
1389 Fleetwood Area H.S. - Fleetwood (PA)
1366 belonged to the Albany Alleycats, I guess that can be removed?
