LONDON, July 1 (Reuters) - Eighth seed Juan Martin Del Potro muscled his way into the Wimbledon quarter-finals with a powerful 6-4 7-6(2) 6-3 win over Italy's Andreas Seppi on Monday.
The Argentine's knee was heavily strapped following a nasty fall in his third-round match, but his slightly cumbersome movement was no barrier to a straight-sets demolition of the 28th-ranked Seppi.
He broke in the seventh game of the first set before wrapping it up in 52 minutes, stayed solid to come through the second in a tiebreak, before breaking in the second game of the third set to effectively end the Italian's resistance.
Del Potro will face Spain's David Ferrer in the last eight.
