LAS VEGAS — Devin Haney retained his undisputed lightweight championship with a unanimous-decision victory over Vasiliy Lomachenko on Saturday in a fast-paced fight before a sold-out crowd at MGM Grand Garden Arena.

Haney was able to control the first half of the fight with his excellent body work and one of boxing’s best jabs, prevailing by scores of 116-112, 115-113 and 115-113.

Lomachenko closed the fight strong with his trademark flurries from uncanny angles, leading to boisterous boos after the verdict was rendered.

The victory over Lomachenko, a future Hall of Famer, was the second defense of Haney’s four 135-pound titles, which he won from George Kambosos in Australia last June.
