Zagórska is retired, Zaniewska doesn't like playing in Poland for some reason
The others are part-time players anyway I think, and usually nail 10K level
Zaniewska still plays at WTA Katowice
She made her last comeback from injury in Sharm El Sheikh, I guess she wants to preserve herself for the moment.
Are you sure about Zagorska's retirement ? I know she doesn't play all year long but I thought she was just in her weeks off now.
Brozda and Kolat have almost disappeared this year, they are barely among the top 1000 players in singles rankings now.
Linette had planned to play all the consecutive indoor French tournaments in October (50k Joué-lès-Tours, 50k Limoges, 100k Poitiers, 50k+H Nantes, 25k Equeurdreville) and 75k Dubai then, but she finally canceled the last two, I guess she took a deserved rest. The same for Kania who was in Asia to play in Taipei the 50k she won and the WTA 125 of this week.
For Piter, I really don't know. She was also in Asia to play the last two WTA 125 Series so maybe she wanted to end her season now, after all she played a lot lately. As for Domachowska, she is in America right now and should stay there as she entered a 25k in Mexico at the end of the month, but she nearly never plays ITF's in Poland anyway.
