I assume the FAA is not issuing TFRs for baseball stadiums where a game is played but no spectators are allowed. Can anyone confirm? The FAA's TFR site (tfr.faa.gov) does not show restrictions for games at Comerica Park in Detroit this week, but it also says do not rely on this site for flight planning. The "UAS data on a map" (faa.maps.arcgis.com) also shows no restrictions. But SkyVector (skyvector.com) did show the usual 3NM restriction for last night's game. NOTAM 4/3621 mentions only the capacity of the stadiums, not how many people are present.
