• Stevenson beats Lopez to become four-weight champion

• Unanimous 119-109 cards underline one-sided outcome

• Miller's hairpiece punched off mid-fight in bizarre scene

Shakur Stevenson delivered the most complete performance of his career on Saturday night, outmaneuvering, outthinking and ultimately outclassing Teofimo Lopez over 12 rounds to claim the WBO and lineal junior welterweight titles and become a four-division champion at Madison Square Garden.

Stevenson cruised to a unanimous decision by identical scores of 119-109, 119-109 and 119-109, numbers that reflected a fight largely contested on his terms from the opening bell. (The Guardian had it 118-110.)
