I was following Ula after Ana beat her in Fed Cup and she was playing really good. R16 of strong Premier 5&M tournaments in Doha and Miami with regular wins over top 100 players and two top 20 wins (Vinci and Stephens). She was stopped only by Serena and Vika on those tournaments (and later by Ivanovic in Miami). But in R1 she struggeld against Maria Sanchez (WTA-112th) and won only after 3 sets so maybe it is good sign for Donna. Anyway, good luck!
