MOSCOW (AP) - Dmitry Chudinov of Russia maintained his unbeaten record by outpointing Denmark's Patrick Nielsen on Sunday to retain his interim WBA world middleweight title.
Chudinov won a unanimous decision over 12 rounds in the town of Mytishchi just outside Moscow, ending Nielsen's unbeaten record in the process.
Chudinov dominated the fight from start to finish but Nielsen managed to hang on until the end, with the Russian fighter winning 116-112, 117-111 and 115-113 on the scorecards.
The Siberia-born Chudinov, nicknamed ''Night Wolf,'' improved to a 13-0-2 record with eight knockouts, while Nielsen is now 22-1.
The Russian won his interim belt in December when he stopped Colombian Juan Camilo Novoa in the sixth round in Moscow.
Kazakhstan's Gennady Golovkin holds the full WBA world middleweight title.
