Britons Cameron Norrie and Dan Evans both claimed comfortable straight-set victories to reach the last 16 of the Barcelona Open.
British number one Norrie convincingly beat Russian qualifier Pavel Kotov 6-1 6-2 in one hour 15 minutes.
Later, Evans beat Italy's Matteo Arnaldi 6-2 6-3 to also progress.
Elsewhere, world number one Novak Djokovic fought back to beat France's Luca Van Assche and reach the quarter-final of the Srpska Open.
The Serb squandered three set points in the opener before 18-year-old Van Assche took the tie-break, but Djokovic broke twice in the second set to force a deciding set and eventually win his opening match 6-7 (4-7) 6-3 6-2.
