Pacquiao vs. Mayweather 2015 odds: Floyd remains steady favorite 4 days from fight

Who’s got the edge on Saturday? The oddsmakers are sticking with the man who’s never lost.

Floyd Mayweather is holding firm as the betting favorite for Saturday night's Mayweather-Pacquiao clash, with Bovada listing the undefeated welterweight superstar at -225 as of Tuesday morning, and Manny Pacquiao a +175 underdog, which is steady for recent days.

The lines originally opened along the lines of -260 to -285 for Mayweather, but eventually worked down to -185 for Floyd. That trend has reversed, settling between those two lines as the cash flows in at amazing rates all over the place for this fight.

Mayweather (47-0, 26 KO) is generally a much larger favorite for his fights, including last year when he was favored -1000 for his first bout with Marcos Maidana, and -800 for their September rematch. Mayweather was around -700 in 2012 against Miguel Cotto, and was around -700 in 2013 against Robert Guerrero.

The closest thing to this line for Mayweather in recent years was his 2013 fight with Canelo Alvarez, where he was listed during fight week at -260 to -280. That fight wound up being a majority decision for Mayweather, though it wasn’t exactly a competitive fight, and the judge who scored it a draw was ushered into retirement shortly thereafter.

Pacquiao (57-5-2, 38 KO) is the underdog for the first time since his 2008 fight with Oscar De La Hoya, when De La Hoya was listed around -180 the day before the fight, with Pacquiao at +150. That fight turned into a one-sided thrashing in Pacquiao’s favor.
