LOS ANGELES (AP) Manny Pacquiao and trainer Freddie Roach have spent the past two months trying to solve the biggest puzzle in modern boxing.

Pacquiao and Roach will reveal their answer in detail Saturday night in Las Vegas, when the fighters meet in the richest bout in boxing history. But clues to a strategy for breaking Mayweather's impenetrable defense were evident in Pacquiao's final workout at Roach's Wild Card gym in Hollywood on Monday.
