LUGANO, Switzerland - Polish teenager Iga Swiatek needed just 54 minutes on Saturday to reach her first career WTA final.

The reigning junior Wimbledon champion defeating Kristyna Pliskova with the loss of just one game, 6-0, 6-1, in the second semifinal.

"I feel great. I'm quite surprised that I'm in the final, because that was my first tournament that I played [directly] in main draw, but I'm really happy that I made it," Swiatek said after the match.

"I was believing in myself, and I hope tomorrow will be a great match also."

Swiatek won the first nine games of the match before the left-handed Pliskova sister got on the board, and she was forced to save six break points across three consecutive service games in the second set to fend off a Czech rally.

Pliskova held 15-40 leads on the teenager's serve at 0-2 and 1-3 in the second set, but was unable to take her chances to get the set back on serve, and also failed to convert on the same lead as Swiatek served for the match.

Despite serving at just 50 percent in the opener, the Polish teenager dropped just one point behind her first serve, and seven points overall on serve, in the opening-set bagel. 

Swiatek totaled 28 winners over the course of the match to just 13 unforced errors, never allowing Pliskova to dictate off the serve or the first shot in the rally.

The Czech landed just 45 percent of her first serves in the match, served five double faults, and tallied double the amount of unforced errors (20) to winners (10). 

The 17-year-old is garaunteed a Top 100 debut for her efforts this week in the Swiss Alps, and by virtue of reaching the final, will be her country's highest-ranked player on Monday.

She will play for her first tour-level title in her third career main draw appearance, having qualifier for both the ASB Classic in Auckland and the Hungarian Ladies' Open in Budapest this year.

"I saw her in a few tournaments, but I'm still new on the WTA tour," the teenager said of Hercog.

"My coach will probably tell me everything - tactics and stuff - so I will be ready."
