(October 24, 2014) SINGAPORE – Semifinal berths and the year-end WTA No. 1 ranking were on the line as the last round of WTA Finals round-robin play began on Friday.
Many scenarios existed to see who would be playing in Saturday’s semifinals, with just Simona Halep having already secured her spot. In the end, Caroline Wozniacki, Agnieszka Radwanska and Serena Williams would complete the semifinal line-up.
Here’s how the day’s matches unfolded:
 Maria Sharapova (Russia) vs  Agnieszka Radwanska (Poland)
Sharapova had to beat Radwanska in straight sets to keep her hopes alive to advance to the semifinals. The two had a messy start to the match as both hit a fair share of errors as they settled in. Sharapova broke first to go up 2-1, but couldn’t consolidate as both players struggled to find their consistency.
Break points were frequent, and it was Sharapova who would get a critical break at 4-4 to serve out the first set. Up 5-4, the Russian was broken after saving three break points so the set was level again at 5-5. But three winners in the next game helped Sharapova break again and she served out the set on her second try, 7-5.
The second set looked to be quick for the world No. 2, who raised her game and Radwanska looked resigned to the loss. Sharapova went up 5-1 and had two match points on the Pole’s serve to clinch a straight set win. From that stage, Radwanska started playing solid tennis and she broke Sharapova’s serve twice to get herself back in the match at 5-5.
Sharapova twice served for the match, but never reached match point on her own serve. The set eventually went to a tiebreaker, and the momentum was still on Radwanska’s side. She was able to nose ahead in the tiebreak as Sharapova errors kept her behind the whole way. Down 6-4 in the tiebreaker, the Russian double faulted to end her chances to advance to the semifinals. By dropping the set, Sharapova was eliminated from the WTA Finals, meaning Serena Williams clinched year-end #1 for the fourth time.
Despite letting the second set slip away, Sharapova was able to regroup and broke Radwanska twice in the third set to win the last four games for the 7-5, 6-7 (4), 6-2 win to end her season with a victory.
Sharapova said after the match that she was happy to end the tournament with a win. “I just really wanted to win this match. I had so many chances and it was just not the way that I wanted to go out in the tournament. That was my goal no matter how physical the match or how tough it was to lose that second set was, I wanted to win it.”
 Petra Kvitova (Czech Republic) vs  Caroline Wozniacki (Denmark)
Wozniacki had already qualified for the semifinals, but she took on Kvitova with the chance to finish 3-0 and finish atop the White Group. Kvitova needed to win the match in order to move on the semifinals, or else Radwanska was in.
Kvitova got off to a solid start, breaking early for a 2-1 lead. But Wozniacki was hitting freely and much more aggressively than usual, most likely due to the fact she had already advanced to the semifinals. The Dane reeled off five straight games to take the first set, 6-2.
The Czech, who admitted that she was feeling “tired and sick of tennis for a moment” after her loss to Radwanska earlier in the week, showed she wasn’t going away and her huge groundstrokes helped her race out to a 2-0 lead. But it all fell apart again for Kvitova, and Wozniacki’s defense and consistency helped her get a key break at 4-3, and she served out the match for a 6-2, 6-3 win.
The victory meant Kvitova, known for her indoor tennis prowess, was out of the 2014 WTA Finals with a 1-2 record and Radwanska finished second in the White Group.
Wozniacki finished atop the White Group and said it’s been a great week so far in Singapore. “It’s been a great week. I think I have nothing to complain about. Great tennis and some good wins. It’s just been really nice. You know, I’ve been playing some really good tennis, and today I think is one of the best matches I’ve ever play.”
 Simona Halep (Romania) vs  Ana Ivanovic (Serbia)
The final round-robin singles match was full of intrigue, as the fate of world No. 1 Serena Williams’ standing at the tournament rested on Simona Halep. If Ivanovic managed to defeat Halep in straight sets, Williams was out and Ivanovic would be in the WTA Finals semifinals for the first time since 2007.
It all seemed to be going Halep’s, and Williams’, way in the first set. Halep jumped out to a 5-2, double break lead and served for the set. From that stage, she lost four straight games as Ivanovic became more aggressive and many Halep backhands, her best shot, repeatedly found the net.
Halep steadied the ship to hold serve down 5-6 and the two engaged in a tense tiebreak. Ivanovic took a 5-2 lead but a forehand error and double fault helped Halep level it at 5-5. The Romanian had a set point up 6-5, but hit a forehand into the net. Ivanovic then hit a backhand long up set point at 7-6 before she managed to grab another set point with a forehand winner and she sealed her first set comeback as she won the tiebreak, 9-7.
The second set moved along similarly to the first set, with Halep showing no signs of giving anything but her all in the match. She again led 4-1 before handing the break back while serving at 4-2. But this time, the Romanian would not relent, and she broke at 4-3 and served out the set at love.
With the loss of a set, Ivanovic would no longer advance to the semifinal stage, meaning Williams was in. But the Serbian fought hard in the third and broke to go up 5-3 in an effort to end her 2014 season with a win. She served out the match at love to take it 7-6 (7) 3-6 6-3.
Ivanovic admitted her disappointment that she did not advance to Saturday’s semifinals. “Yeah, it’s mixed emotions obviously because I feel like it was such a great match tonight, yet it’s such a low not to be able to qualify for the semifinals. Still, on a positive note I won two matches, finished the season with a victory. It’s been amazing year for me.“
So, the semifinals will be Williams against Wozniacki and Halep versus Radwanska. Williams leads the head to head 9-1, while Halep leads hers 4-2.
