Not that it would matter, but if CW offers up reruns of Supergirl on Mondays, they may be pre-empted in NYC by Yankees or Mets baseball on WPIX 11, which mainly is put the PIX11 logo on coverage from the YES Network or SNY respectively. I remember years ago when both teams had more broadcast game available not on just 11, but channel 9 (WOR-TV/WWOR) as well. But that's me showing my age (43)
And looking from
PIX's website on the Yankees side of the ledger, there is
ONE Monday night game...June 26th in Chicago against the White Sox.
As for the Mets, no Monday games are scheduled.
And if any show gets pre-empted, it gets sent to the Saturday 8-10 spot, provided there isn't baseball or any other programming.
