Bump. Great match up and a real dog fight. Morales makes this a tough fight for Pedroza but will get outworked as the fight goes on. Pedroza's slick movement and workrate will favor him down the stretch.
Pedroza is clearly the greater FW, based exclusively on work done in that weight division, whilst I think Morales is probably just slightly the greater p4p based on their entire career achievements at all weights. H2H at 126lbs, I'd make Pedroza a narrow favourite to win a close decision, but it could go either way.
Pacquiao wasn't in his prime against Morales he improved significantly after their 1st meeting, and even in the 1st fight Pacquiao had a horrendous cut from a headbutt from Morales, and still made it a very close/competitive fight. Now to be fair to Morales he also lost a step in fights 2 and 3 vs Pacquiao, but there's no doubt that Pacquiao improved as a fighter after the 1st Morales fight.
