SINGAPORE – Karolina Pliskova marked a memorable debut at the BNP Paribas WTA Finals Singapore presented by SC Global by defeating Garbiñe Muguruza from match point down on Monday.

A couple of hours on from Svetlana Kuznetsova’s back-from-the-brink victory over Agnieszka Radwanska, Pliskova produced an even more unlikely turnaround to triumph, 6-2, 6-7(4), 7-5.

“Inside I’m still in shock that I won this one. Inside I still believed that I could win, but she was playing so well in the second and third sets,” Pliskova told BT Sport after stepping off the court. “There’s always a chance in tennis until it’s done, so I’m really happy with the win today.”

No.4 seed Pliskova was quick out of the blocks, dropping only seven points on serve en route to the first set. When she then broke at the start of the second, a comfortable victory looked on the cards. However, Muguruza, making her second appearance at the Finals, made a better fist of the second set, drawing level before recovering from 3-0 down to take a scrappy tie-break.

With confidence now coursing through her game, Muguruza surged 4-0 ahead in the decider. Try as she might, though, the Spaniard could not find the knockout blow, dropping serve in a 15-minute sixth game to leave the window ajar for a comeback.

At 5-2 she arrived at match point, only to snatch at a routine volley. The mistake proved costly as Pliskova found a second wind, rattling off 15 of the last 19 points to snatch victory from the jaws of defeat.

Despite being broken five times, Pliskova still struck 14 aces in her two and a half hours on court, taking her annual tally to 522. This number is nearly 200 more than her nearest competitor on tour, Serena Williams (324), or at the WTA Finals, Madison Keys (277).  

Pliskova will next play on Wednesday, taking on fellow comeback queen Kuznetsova.
