Pacquiao vs. Mendones was scheduled for 8 rounds, the time of the TKO was 2:45 of the 2nd round.
Pacquiao vs. Torrecampo was scheduled (to the best of my knowledge) for 10 rounds, the time of the KO was 0:29 of the 3rd round.
Pacquiao vs. Sung-Yul Lee was scheduled for 10 rounds, the time of the TKO was 1:51 of the 2nd round.
The only thing that's the least bit doubtful is the Torrecampo fight, I'm not 100% sure that it was 10 or 12 rounds, but it's definitely not less than 10.
