Roger Federer moved up to No. 4 in this week’s ATP Tour rankings, his highest position since last June. He trails No. 3 Stanislas Wawrinka by 515 points.
Federer and his replacement at No. 5, Tomas Berdych, both passed David Ferrer, the 2013 Sony Open finalist who fell from fourth to sixth after losing in the fourth round in Miami. The fifth spot equals a career high for Berdych, who reached the semifinals last week before withdrawing with gastroenteritis.
Federer, who lost to Kei Nishikori in the Miami quarterfinals, joins No. 1 Rafael Nadal and No. 2 Novak Djokovic as so-called Big Four members in the actual top four. The fourth, Andy Murray, slipped from sixth to eighth after following up his 2013 Sony Open title with a quarterfinal loss to Djokovic last week. This is Murray’s lowest ranking since 2008.
