Round nine: A quiet round between the ropes but the previous three minutes has certainly awoken the crowd. Cotto may well be on a second wind here, and has the slightest of edges in a relatively tame ninth. Cotto 84-87 Mayweather
Round 10: Cotto has a little momentum and looks to turn up the pressure, but the counter-punching of Mayweather is returning to the heights from earlier in the fight and with six minutes remaining that is an important round for the challenger after losing his way for a while. Cotto 93-97 Mayweather
Round 11: The champion tries to keep Mayweather penned in the corner but even his best flurries are struggling to phase the 35-year-old. The challenger moves into the middle to deliver a few select shots which rubber-stamp another round, and Cotto will need to somehow knock out the man he has barely troubled to keep his title. Cotto 102-107 Mayweather
Round 12: Mayweather finishes strong with an uppercut halfway through the closing round which loosened Cotto's legs momentarily but he is unable to finish the fight with further solid shots in the final 60 seconds and at the final bell Cotto cuts the figure of a man who knows his reign is up.
