She had to get through a tiebreak to do it, but 3rd seed Kim Clijsters defeated Ekaterina Makarova in straight sets Monday in the Australian Open round of 16. Clijsters' 7-6, 6-2 win over Makarova now puts her in contention with 12th seed Agnieszka Radwanska in the quarterfinals. If she defeats Radwanska (and, with Radwanska's weak serve, she probably will), she will play either Petra Kvitova or 2nd seed Vera Zvonareva in the semifinals.
Speaking of Radwanska (who has made an amazing comeback from surgery and rehab): Why does such a brilliant tennis player not drop everything until she has learned to hit a reasonably good second serve? Her first serve is better than it used to be, but even that failed her toward the end of her round of 16 match; her second serve is a disaster. Radwanska can outplay just about anyone on the tour, but she has this major flaw in her game, and I don't understand why someone doesn't do something about it.
