Federer and Wawrinka set up all-Swiss showdown
The winner of Sunday's Indian Wells Masters final will definitely be Swiss, after Roger Federer and Stan Wawrinka both won their respective semi-finals on Saturday.
While Federer faced a potentially brutal draw heading into this event, his job was made somewhat easier by other results.
He was able to avoid meeting Novak Djokovic after he got knocked out by Nick Kyrgios, and was then given a walkover into the semi-finals when Kyrgios withdrew from their last eight match with a suspected bout of food poisoning.
Federer avoided another seed in Kei Nishikori when Jack Sock defeated the Japanese star in the quarter-finals, and so it was Sock he came up against on Saturday.
The match did not provide the in-form Federer with too stern a challenge, as he wrapped up a 6-1, 7-6 (7-4) victory in 74 minutes.
After being brushed aside by Federer in the first set, Sock was much more competitive in the second, but his resistance would eventually crumble in the tie-break, as the Swiss ace won six of the last seven points to secure the win.
As for Wawrinka, he had far too much firepower for Spaniard Pablo Carreno-Busta, racing to an emphatic 6-3, 6-2 victory in just over an hour.
Sunday's final represents a big challenge for Wawrinka, who has only managed to beat Federer three times in their 22 previous meetings.
The duo last met in the Australian Open semi-finals, where Federer secured a five-set victory on the way to winning the title.
