Swiss Indoors: Juan Martin del Potro sets up final showdown with Roger Federer in Basel

Juan Martin del Potro beat defending champion Marin Cilic for a seventh time in a row on Saturday to set up another Swiss Indoors final showdown with Roger Federer. Del Potro took advantage of an error-strewn Marin Cilic to score a 6-4, 6-4 win over the world number four.   

Federer easily overcame David Goffin 6-1, 6-2 to reach the final of his hometown tournament for the 13th time. The match lasted exactly one hour. Federer has won seven and lost five of the previous finals, with two of those defeats against Del Potro in 2012 and 2013. However, overall the Swiss has beaten the Argentine 17 times out of 23.

"I played a smart match, I waited for my chances in both sets," Del Potro said after his win. "The only way to beat Roger is play hard and play aggressively all the time... you have to play down the lines every time and sometimes even that is not enough."

Cilic never found his rhythm and did not help his cause with a flurry of unforced errors, including six double faults. After early breaks by both players, Del Potro won the ninth game with a backhand return and held serve to clinch the first set.

The Argentine, emerging as a late contender to snatch one of the last two places at the ATP World Tour Finals in London, then broke immediately in the second. Cilic broke back at 3-3 but Del Potro did the same in the next game and there was no way back for the Croat with Del Potro wrapping up the match with his seventh ace.

Federer never allowed his Belgian opponent to settle as he reached his eighth final of the season. There were no signs of the jitters that resulted in him dropping his only set of the tournament in Friday's quarter-final against Adrian Mannarino.

"Everything changed completely, I had a much better mindset. I wanted to take it to my opponent and I was able to do that," said Federer.
