The No.1-seeded Radwanska was the first to move through and it was plain sailing, as she needed just 64 minutes to end the run of Lara Arruabarrena, 60 62. Radwanska's serve was particularly effective - eight aces to zero double faults - and she finished fast, winning the last 15 points of the match.
"It was definitely a very good match - I was playing really good tennis," Radwanska said. "It was really hot out there but I played my 100% throughout the match, so that's why it was two quick sets."
Radwanska didn't know about the 15-point run until she was told about it in her press conference.
"Really? I didn't even notice!" she replied. "It was just so hot out there, I didn't even realize it!"
There was another funny moment in Radwanska's press conference when the Korean media asked her how she feels about playing in Seoul for the first time, and after all kinds of positives - the courts, the hotel, the people - they pressed her for any negatives she could come up with. And she did.
"There are a lot of spiders around the practice courts, and it's scary!" the World No.4 said.
The No.3-seeded Pavlyuchenkova followed Radwanska into the final, but she definitely had it much tougher. In an impressive display of serving - there were only two breaks in 24 service games - she battled past Francesca Schiavone in a pair of tie-breaks, 76(11) 76(6), saving three set points in the first set tie-break and battling back from 3-0 down in the second set breaker to close it out.
"I'm so tired right now, to be honest!" Pavlyuchenkova said. "I'm happy to be in the finals, but I'm still thinking about the match, how tough it was. The first set was amazing - we were both playing good tennis, and we played an hour and a half for just one set, but then I was so tired afterwards that I knew I had to hold serve in the second set, because if I didn't, it would just be over. I'm happy I did."
Both Radwanska and Pavlyuchenkova have winning records in WTA finals (12-5 for Radwanska, 5-2 for Pavlyuchenkova), and both are even better in International-level finals (4-0 and 5-1, respectively).
Radwanska leads Pavlyuchenkova in their head-to-head, 2-1, though only one of those meetings came in the last four years - a tight two-setter in Radwanska's favor at the US Open a few weeks ago.
"I have to be aggressive but also consistent," Pavlyuchenkova said. "We just played at the US Open and she's very consistent, she never misses, and if I make a lot of mistakes it'll be an easy victory for her. It'll be a tough match for me, but it's the finals, and I hope I'll be feeling 100% tomorrow."
