Swiatek leaves it all on the court in Melbourne

First things first: Here's how 2018 Wimbledon girls' champion, and now major presence on the WTA Tour, Iga Swiatek wants her name pronounced: Shvee-on-tek.

"In Polish, it's gonna be better," she says.

The second big thing to know about Swiatek—ranked No. 56 at age 18, though she missed much of 2019 injured—is that her game is both a fiery one and a spontaneous one.

Her 42 winners from her fourth-round Australian Open match on Monday came not only from her fierce forehand and accurate backhand, but also out-of-nowhere variety plays—such as this silky drop shot when she already had the upper hand in a baseline rally:

Swiatek would go on to break Anett Kontaveit in that game, and win the first set in a tiebreak.

Set 2 was close as well, but that wasn't enough to scare Swiatek into playing it safe.

Serving to stay in it down 4-5, Swiatek saw a short ball worthy of a trip to the net, but doing it on a forehand would be too predictable, so she went between her legs instead—and followed it in for a point-ending forehand volley.

"Hey @NickKyrgios@Gael_Monfils, is it good enough?" she'd say on Twitter afterward.

The tweener seems to now be a regular part of Swiatek's tennis repertoire. She also tried it in her straight-sets win over No. 19 seed Donna Vekic.

Swiatek got the point and the hold against Kontaveit, but she later blinked to drop the second set.

In the third set, Kontaveit took a 5-1 lead, twice breaking Swiatek, who made less than half of her first serves over the course of the match. Swiatek reeled off four consecutive games to even the score at 5-5, but in the end, Kontaveit, the No. 28 seed at age 24, proved to have steelier nerves in the most important moments.

She took the match, 6-7, (4), 7-5, 7-5, to make her first major quarterfinal, successfully following up on her third-round thrashing of Belinda Bencic. In the quarters, she takes on reigning Wimbledon champion Simona Halep.

As for Swiatek, remember how to say her name. She'll be around a lot more.
