The six knock-downs he inflicted on a road-runner in reverse called Chris Algieri thrilled the packed south-east Asian crowd in the CotaiArena but were not quite enough to finish off the American.New York’s holder of degrees in medicine and nutrition looked after his health through 12 rounds spent going backwards so fast and so far that if they had taken out the ropes he would have backed himself into the car park of the Venetian casino.Mere survival is not enough in a world title fight. So perhaps Algieri’s real achievement was that of preventing the PacMan from sending him so far into oblivion that it may have frightened Floyd Mayweather from ever agreeing to the richest fight in ring history.Team PacMan had considered carrying Algieri a few rounds so as not to look too devastating on television back in Mayweather’s home town of Las Vegas.As it transpired, Algieri did that job for him by being fit enough to run a marathon while facing the wrong way and - well, yes - brave enough to keep getting up every time Pacquiao bowled him over.So when he was asked if him against Mayweather might finally happen, the PacMan was able to say: ‘Yes, I want that fight and the fans deserve it.’He praised Algieri for regaining a vertical position once in the second round, twice in the sixth, twice more in the eighth and once again in the ninth.His fabled trainer Freddie Roach disagreed with that assessment, saying: 'All he did was run. He showed none of the guts that got him off the canvas to win his light-welter title against Ruslan Provodnikov.'Algieri was stripped of that belt the second the first bell rang here, for accepting this catch-weight fight for Pacquiao’s world welterweight title.Where he goes from here after a performance trying to smother the life out of a major television event is anybody’s guess.But Pacquiao is still on course for a date with destiny and a large share of a potential one-billion dollars purse in Las Vegas, Money Mayweather agreeing.Even though Algieri refused to join the party, Pacquiao was able to demonstrate that his punching power is almost regenerated to the level which destroyed our own Ricky Hatton in 2008.The heaviest knock down was the first of the two in the sixth. Somehow Algeiri made it to the bell even though it could easily have been stopped then by the referee, his own corner... or one more blow of that magnitude from Pacquiao.Bakudaily.Az
