Nagy's currently ranked 126, she's a clay-court specialist and has recently won 25K and 50K challengers. She won a 25K challenger on the hard courts of Mexico earlier this year but generally she's not as effective on faster surfaces, being beaten 6-0, 6-1 in rd1 of Wimbledon qualifying by a similarly ranked player.
They've never played before.
Incidentally in case anyone hasn't heard this, some newspapers likened Melanie to Bridget Jones as played by Renee Zellweger, in the aftermath of her rd1 Wimbledon victory. Melanie was quite shocked at hearing this, lol
