Andy Murray is through to the last 16 of the BNP Paribas Open in Indian Wells following a hard-fought 6-3 6-2 win over Lu Yen-Hsun.
The world No 3 had lost to Lu at the Beijing Olympics in 2008 and had to survive an early onslaught to secure victory in an hour and 28 minutes.
Lu created five break-point chances but failed to take any, with Murray now set to face Carlos Berlocq in the fourth round.
