And you believed what they told you? I asked the same question about playing Saturday. The report I have is (although it was not raining) the rain the day before left the field in less than good playing condition. If I remember correctly, it had rained much of the week leading up to the three game set. The field did not have time to drain properly so, with the safety of the players in mind, the games were moved back a day.
This is not the first time Cador has not played a game (against sTu) that would not enhance his position in the tournament. His quota of games were met and even if su had won (on Monday) their seeding in the tournament would not have improved. I will bet you a dollar to a doughnut if su had taken both games on Sunday, Cador would have played Monday.
