Cameron Norrie, 26, will compete in his seventh ATP final in 2021; the British No. 2 will face the second seed in a match that promises plenty of action.
Casper Ruud, meanwhile, will compete in the final on Sunday after the Norwegian defeated Bulgarian Grigor Dimitrov.
Norrie advanced to his fifth singles final in 2021 by defeating the Russian top seed.
Rublev won the first set 6-3 in 35 minutes after Norrie, 26, was broken in the fourth game of the match, giving Rublev a 4-1 lead.
Norrie discusses his ‘big win’
Norrie, who won his first ATP Tour championship in Los Cabos earlier this year, saved three break points in the third game of the second set before breaking at 3-1 after a backhand volley by the Russian went just wide.
In California, world No. 28 did not abandon his lead, forcing a third set before breaking Rublev early in the decisive set and eventually holding firm to win.
“All credit to Andrey because he came out firing and played some big tennis at the beginning and then I managed to weather the storm,” Norrie said, as per reports on The Guardian.
“This is such a big win for me, I am good friends with Andrey so it is not easy playing against him. It is definitely a match I will remember for a long time.”
Norrie will face Casper Ruud in the final after the Norwegian beat Bulgarian Grigor Dimitrov.
