In the spring, the WTA’s perennial No. 1 player, Serena Williams, announced she was pregnant and wouldn’t play the rest of the season. By the summer, it was clear that the woman who had taken the top ranking from her in 2016, Angelique Kerber, wasn’t ready to defend her crown in 2017. That left the WTA’s No. 1 spot wide open for whoever could claim it. The mad scramble was on.
Since then, Karolina Pliskova, Garbiñe Muguruza, and Simona Halep have all claimed the top ranking for the first time. But as the women sprint for the finish line at the WTA Finals this week, the race is still as open as ever. More so: Seven of the eight players in action in Singapore have a chance to finish 2017 at No. 1—only the late-qualifier Caroline Garcia is out of the running.
Who will reach the tape first? And what else should we be watching for in Singapore? Here’s a look at what’s in store, and what’s at stake, for each of the eight contenders.
