Round 12
12:43: It's over. They went the distance. Pacquiao raises his hands, but most have it scored for Mayweather.
Round 11
12:40: Mayweather now in full-on "dance away" mode after coming out of his corner with a flurry of punches. Floyd likely leading but it remains close. Buckle up for the final round.
12:39: The story you all really want — Jimmy Kimmel dressed up as Justin Bieber in prefight .
Round 10
12:37: Another round for Floyd, who's spent more time in control than not.
12:34: Pacquiao finally does a bit of damage as he gets Mayweather into the ropes.
Round 9
12:31: Most experts believe Mayweather is in control with three rounds to go. Pacquiao the clear aggressor but not landing nearly enough punches. Mayweather seems unfazed.
Round 8
12:30: These scores are all over the place, but I'm seeing mostly Manny in Round 8. Very, very close overall. Four to go, folks.
12:27: Pacquiao turning up the aggression, lands a pair of hard lefts early in the round.
Round 7
12:26: Another round for #TheMoneyTeam, but it remains tight. Don't say we didn't warn you if this happens:
This has judging controversy written all over it.

12:23: Spoke too soon — many had a split or Pacquiao in the last round. Mayweather remains ahead on most cards. Early action in Round 7 looks like a strange, shirtless game of tag.
Round 6
12:22: Floyd is taking over, so here's a Vine of him eating a punch.
12:19: Pacquiao unleashing body blows — Mayweather looks up and shakes his head. Actually mocking him now.
Round 5
12:15: Easy round for Mayweather, who is putting distance between himself and Pacquiao on most of the unofficial ringside cards.
Round 4
12:14: Score that round for Manny. Different cards now diverging, but most still giving overall edge to Mayweather.
12:11: Pacquiao is TEARING into Mayweather with the first furious series of punches. Floyd officially paying attention to the proceedings.
Round 3
12:10: Looks like Pac gets Round 3. That's 2-1 in favor of MM. We've got a great one building. Action picking up quickly.
12:07: Manny going to the body and landing punches early. Those yellow trunks are moving in with every opportunity.
Round 2
12:06: Pacquiao missing most of his punches but getting more aggressive. My sources are scoring this 2-0 in favor of Mayweather.
12:04: Shouts of "Manny! Manny!" following a nice body shot. Mayweather wrapping up early and often.
Round 1
12:02: Consensus among boxing experts is a solid round for both, but edge to Floyd. Had all the excitement of Lap No. 1 in a NASCAR race.
Midnight: We're underway. This thing actually is happening.
A lot of jabbing, but a single lead right landing early from Mayweather. Put on another pot of coffee because this is likely to be a long one.

11:17 p.m.: Looks like this pay-per-view issue is going to delay the fight 45 minutes. Where's the coffee?
Talked to HBO VP Mark Taffet. Says because @TWCable ordering issues, broadcast will be "slowed down." Trying to give TWC time to rectify.
— Chris Mannix (@ChrisMannixSI) May 3, 2015
Taffet told SI there could be about 45-minutes of fill time before the main event. Said ordering problems were nationwide.
