Gennady Golovkin extended his record to 29-0 with the 26th stoppage of his career to defend his IBO and WBA World Middleweight titles against Ghana's Osumanu Adama.
Adama was no match for the highly skilled Kazakh champion, who put his man on the canvas in the opening round and then again in the sixth as he smelled blood.
Golovkin underlined his reputation as one of the world's most exciting fighters with his win, but he was forced to remain patient during the early rounds as Adama made things awkward.
The 31-year-old champion motored into the seventh round and dropped his man for a third time in the fight before referee Luis Pabon stepped between the two and waved the contest away.
28-0 middleweight top dog Gennady Golovkin looks to defend his IBO and WBA World Middleweight titles to kick off his 2014.
The Kazakh hitman (right), who won all four of his fights last year by stoppage and has now racked up 15 early finishes in a row, returns to the scene of his March 2012 win over Nobuhiro Ishida in Monaco.
US-based Ghanaian 33-year-old Osumanu Adama brings a 22-3 record into the ring with 16 knockouts. His one previous world title challenge - a March 2012 attempt at Daniel Geale's IBF title - ended in a unanimous decision loss.

It was a brave and battling performance from Ireland's Roman Belaev, but he found himself over-powered and out-skilled by the hard working Russian Roman Belaev.
Belaev, 23, underlined his growing potential with a heavy-handed display to add the WBA Continental title to the WBF belt he already holds in a busy welterweight division.
The Russian looked comfortable throughout the fight, while now 17-3-1 Byrne absorbed a number of body shots well and showed great determination to survive to the end of the contest.
The scorecards came in handing Belaev a resounding and unanimous win; they read 119-109, 120-106, 119-109 in his favour.
Dublin favourite Dean Byrne faces one of the biggest fights of his career as he attempts to win the Vacant WBA Continental Welterweight Championship against 12-0 Russian Roman Belaev.
Ireland's Byrne has won 17 of his 20 career bouts, and enters the bout on a three fight unbeaten streak.
But it's a stern test that awaits him in the form of up and coming Kaliningrad-born, German-based welterweight Belaev, who has won 10 of his 12 fights by knockout.
