WIMBLEDON, England (AP)—Britain’s Andy Murray has moved impressively into the fourth round of Wimbledon after defeating Frenchman Gilles Simon in straight sets.

The fourth-seeded Murray beat the 32nd-ranked Frenchman 6-1, 6-4, 6-4 in under two hours.

Murray conceded only 15 points on serve and did not face a single break point.

He also hit 15 aces and broke his opponent three times from as many chances in the opening two sets.

Murray goes into the fourth round as one of just three players who have not dropped a set.

He faces either Sam Querrey or Xavier Malisse on Monday for a berth in the quarterfinals.
