7-Day Weights: Mayweather at 148.5, Guerrero at 153

by David P. Greisman

Floyd Mayweather was already nearly at the welterweight limit about a month before his May 4 pay-per-view main event against Robert Guerrero at the MGM Grand in Las Vegas — and with a week to go, he was even closer.

Robert Guerrero, meanwhile, still had half a dozen pounds to lose in half a dozen days, according to figures provided by World Boxing Council official William Boodhoo.

Mayweather came in at 148.5 pounds on April 26, according to the WBC. Guerrero was at 153 pounds on April 27.

The maximum either fighter could have been is 154 pounds. The WBC’s 7-day weigh-in requires fighters to be within 5 percent of the division limit. Mayweather had seven days to lose the final 1.5 pounds. Guerrero had six days to lose six pounds.

Interestingly, neither boxer was much heavier at their 30-day weigh-ins. Mayweather came in at 149.6 pounds on April 5, while Guerrero came in at 154 pounds on April 4.

This fight is for a title belt that Mayweather won in 2011 with his knockout of Victor Ortiz. Mayweather subsequently went up to junior middleweight for a bout with Miguel Cotto, and that allowed Guerrero to capture the WBC’s interim title at welterweight in a win last year over Selcuk Aydin.

Guerrero, 30, subsequently defended the interim title successfully in November with a decision win over Andre Berto. That victory brought his record to 31-1-1 with 18 knockouts and 2 no contests.

Mayweather, 36, has not fought in nearly a year and is also making his first appearance in the ring since a jail stint last summer. His unanimous decision win over Cotto brought his unblemished record to 43-0 with 26 knockouts.
