Within the span of 20 minutes, Kim's draw just got a lot easier
Both Jankovic and Kleybanova out. Either one could have been a test for her in the QF: Kleybanova because she's pushed Kim to two 3rd set tiebreaks in the past year winning once, and Jankovic, not because of form, but because she is a tough match-up for Kim given that she makes her play a lot of balls and complicates her ballbasher mode.
You could say Nadia is a potential test in the 4R, but I don't think anyone believes 2010 can be repeated.
Kim's basically in semis and there's a good chance she'll have to step it up in a big way against Zvonareva on that day.
