Miami, USA, 25 March 2012 | AFP

Roger Federer set up a 24th career meeting against old rival Andy Roddick on Saturday as both men eased through the Sony Ericsson second round.

Third-seeded Federer, who has a 21-2 record against world No.34 Roddick, recorded his 23rd win of 2012 by beating 19-year-old American wildcard Ryan Harrison 6-2 7-6(3).

The Swiss superstar is bidding to capture his third Indian Wells-Miami title double, having also won the back-to-back US hardcourt Masters events in 2005 and 2006.

Federer has now won 40 of his past 42 matches since the 2011 US Open semifinals.

Roddick, the 2004 and 2010 champion in Miami, dropped nine points on his serve and hit 10 aces to beat Luxembourg’s Gilles Muller 6-3 6-2.

The American, who is at his lowest ranking since July 2001, won in 74 minutes.
