Britain's Joe Salisbury backed up the achievement of becoming doubles world number one by winning the Monte Carlo Masters with US partner Rajeev Ram.
The top seeds beat sixth seeds Juan-Sebastian Cabal and Robert Farah, of Colombia, 6-4 3-6 10-7.
In a clinical display, Salisbury excelled both at the net and with overheads, ably supported by Ram's powerful serving and volleying.
Salisbury and Ram claimed their first clay title as a pairing.
They produced a dominant display in the first set, but their level dipped in the second as Cabal and Farah stepped up the pressure, breaking serve after a shot came off the net cord and hit Ram in the groin.
