LONDON (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.
