Sergei Malatov
Sergei "Serge" Malatov (Ukrainian: Сергій Малатов) is a fictional character on the HBO drama series The Wire, played by Chris Ashworth. He acts as a driver and enforcer for The Greek. He is Ukrainian, although Americans often assume he is Russian. He hates this and their subsequent tendency to nickname him "Boris". He is responsible for picking up containers of smuggled goods from the port and taking them to The Greek's front warehouse to be fenced.
Biography
Malatov is a trusted lieutenant in The Greek's import business. He is said by White Mike to be "straight muscle." When vodka, appliances, electronics, drugs or Eastern Bloc women destined to be sex workers arrive in Baltimore, Sergei ensures the cargo is delivered to The Greek's associates in the city. He mentions that he has spent four years in prison in Ukraine, and that American prisons are nowhere near as harsh.
Season two
Sergei is supposed to collect thirteen prostitutes hidden in a cargo container from the docks, but when he does not receive the all-clear signal from The Greek's accomplice on the ship which delivered the women, he abandons the container on the waterfront. The Greek later learns that the girls were killed, and Sergei is sent to the Philadelphia port (the ship's next destination) to find the crewman. He infiltrates the port and captures the crewman. When The Greek and Spiros "Vondas" Vondopoulos arrive, the crewman tells them everything about how the girls were killed, and Spiros murders him. Sergei is charged with disposing of the body and The Greek instructs him to make sure there is no face or fingerprints. The body is later found and identified by a tattoo.
