Boxing: Harrison shakes off complacency to beat Colombian

On Saturday night Scott Harrison found out just how dangerous complacency can be in professional boxing when he met the little known Colombian Walter Estrada.

Harrison stopped Estrada in round five to retain his World Boxing Organisation featherweight title, but the first three rounds were difficult. Estrada had travelled for more than 30 hours to get to Glasgow having accepted the fight at eight days' notice, when William Abelyan withdrew.

Now Harrison must meet Abelyan in a mandatory defence before he can move on and unify the 9st division, which has been his intention since he first won the WBO's portion of the title in 2002.

Fighters seldom admit to underestimating opponents but clearly Harrison believed the Scottish papers that insisted Estrada was a hopeless fall guy. There were moments in the opening session when Estrada's exquisite bolo left counters were finding the target again and again. Even Harrison's corner seemed perplexed and it took them a few rounds to avoid the dangerous art of the punch that was first used by Cuban fighters in the 1930s.

But by the end of round four, as Estrada fell to the canvas for the first of three visits, no amount of bolo punches could save him and after 63 seconds of round five the referee stood over him and waved his arms to end the brief encounter.
