PLISKOVA STAYS ALIVE » Karolina Pliskova can still win the U.S. Open and keep her No. 1 ranking, thanks to a big comeback Saturday.

Pliskova fought off a match point in the second set and rallied to beat No. 27 Zhang Shuai of China 3-6, 7-5, 6-4 to advance to the fourth round.

The runner-up last year needs to at least return to the final for a chance to remain atop the rankings when the year’s final major tournament is over, and it appeared for a while that the Czech wouldn’t get close.

But she stayed alive while trailing 4-5 in the second set, then pulled out the third after receiving treatment from a trainer on her right forearm between sets.
