Stan Wawrinka has routed Pablo Carreno Busta 6-3 6-2 to reach the final at Indian Wells after needing third-set tiebreakers to win his previous two matches.

Wawrinka will play four-time champion Roger Federer or American Jack Sock in Sunday’s final.

Wawrinka dispatched Carreno Busta while never facing a break point in the 64-minute match on Saturday. The Spaniard fell to 0-3 in his career against the Swiss.

No. 21 Carreno Busta was the lowest seed to reach the semi-finals at the desert tournament since 2014. It was the biggest semi-final of his career, having failed in 16 previous tries to reach that round in an ATP Masters 1000 event.

Wawrinka advanced to his first Indian Wells final, having lost in last year’s semis.
