A day after throwing his shoes in frustration, Juan Martin del Potro won 18 of 23 games to reach the third round at Wimbledon with a 6-7 (7), 6-1, 6-0, 6-4 win over Olivier Rochus.

Del Potro took his shoes off after Wednesday's match was suspended by darkness after the first set and threw one out of the stadium and the other one deep into the crowd.

When he came back onto Court 2 Thursday, he dominated by winning 12 of the first 13 games.

Del Potro won the 2009 U.S. Open, but has struggled with injuries.
