LAS VEGAS (AP) — The pressure of a $180 million payday never got to Floyd Mayweather Jr., even if the richest fight ever wasn't the best.  Using his reach and his jab Saturday night, Mayweather frustrated Manny Pacquiao, piling up enough points to win a unanimous decision in their welterweight title bout.  After the fight, it was disclosed that Pacquiao injured his right shoulder in training and that Nevada boxing commissioners denied his request to take an anti-inflammatory shot in his dressing room before the fight.  [...] he said paperwork filed with the commission didn't check the injury box, and the Nevada commission ruled against the request for a shot.  Nevada Athletic Commission chairman Francisco Aguilar said Pacquiao's camp wanted shots that included lidocaine, a drug that numbs the affected area.  Pacquiao landed probably the biggest punch in the fight in the fourth round — a left hand that sent Mayweather into the ropes — but he wasn't able to consistently land against the elusive champion.  The fight was a chess match, with Mayweather using his jab to keep Pacquiao away most of the fight.  In the final seconds of the fight he raised his right hand in victory and after the bell rang stood on the ropes, pounding his heart with his gloves.  Five years in the making, the fight unfolded before a glittering crowd of celebrities, high rollers and people who had enough money to pay for ringside seats going for $40,000 and up.  Boxing fans called for the fight to be made five years ago, when both men were in their undisputed prime.  [...] it was enough to settle the question that boxing fans had asked for years — who would win the big welterweight matchup of the best fighters of their time.
