Great win for Julia, coming back from a 1-6 first set to take the next 6-2, 6-3
The kind of wins she did in her "Australian summer" late 2010 to early 2011, when she cracked the top 200 for the first time.
SF opponent, another young American Pegula, is also tricky. She's 18, just outside the top 200, and did knock out the top seed Minella in R1.
A win surely means top 150.
