Netfan, I agree with your first two points, but not the final one – umpires attending training before matches is standard practice and has been for years (as is meeting with coaches after a match, which was raised earlier in the thread).
Umpires need practice too, and the transistion from a tournament of teams ranked in the 20s to a 1v2 match without any exposure to the faster pace at that level to prepare would be madness. Neither umpire would put Sunday’s game in their highlights package, but both Yuliani and Stevenson impressed me at the world cup, in factI thought Yuliani deserved a higher ranked play-off game than she eventually got. One clear learning from this series (and the world cup) is that INF needs somehow to find the resources to invest in umpire development. Getting Yuliani and other Singapore-based internaitonal qualified umpires onto the SSN roster would be a good start.
