But Bencic held her next two service games with authority and broke for a 5-3 lead, finally sealing the match with a serve that was too much for Pliskova.
The 13th seed's serving accuracy was not as precise as it has been, with just over half of his first deliveries finding the target, but when he was able to get one in play the Canadian won 88 percent of those points.
"I'm not putting pressure on myself even now", the 22-year-old said. "In the first set I was moving everywhere and when I have the chances to move her". Andreescu in particular seemed to be running out of steam - and it showed as she dropped her serve in the third set's sixth game.
It took Kerber several games in the opening set to get used to Williams' changing tactics. She's a good mover, great fighter.
She broke Kerber three times in the third set, rallying from a 3-2 deficit to take four of the final five games. "To play against Venus, it's always tough". "Slows down the pace and plays higher, then suddenly accelerates or plays angles". But it wasn't enough. But Andreescu mustered her last reserves of energy to break back and capture her first main WTA Tour title.
Bencic won her 12th straight match toughing through former No. 1 Karolina Pliskova 6-3, 4-6, 6-3.
Thiem trailed 4-3 and 5-4 in the third set before breaking Federer with a forehand victor to go up 6-5.
"I was really trying, in the first set especially, to find my rhythm and play my tennis but it was not so easy", she told reporters.
"I'm trying to be as calm as him". "I'm not going to the court with any expectation".
Bencic next plays the victor of Thursday's match between No. 8 Angelique Kerber and Venus Williams.
"It will be completely different match tomorrow", Kerber said of Bencic. Considering Bianca Andreescu is playing an exceptional received in Kerber, she will have to improve her serve since it is a weakness which the German superstar is exceptional at exploiting. "It will be a battle". "I just started playing these high-level events a year ago, and I think I'm gaining more and more experience after every match".
Bianca Andreescu completed her emergence as the latest new star of women's tennis after a scintillating three-set win over Angelique Kerber in the final of the BNP Paribas Open at Indian Wells. The next couple of games I did the same thing. "And I think this year all the wins have definitely given me confidence". "I was really nervous. I really enjoy the semi-finals here - it was already twice here, and I'm really happy to be in the final for the first time now". "I learned a lot, and I have been implementing what I have learned throughout this whole tournament".
For Williams, Friday will require a reset of her own as she prepares for next week's Miami Open - and the rest of the season.
But who is Indian Wells' wildcard sensation?
