Robert Guerrero and Yoshihiro Kamegai tipped the scales below the welterweight limit today for tomorrow night's Showtime main event, and the rest of the main card fighters also made weight for tomorrow's event from the StubHub Center in Carson, California.
Guerrero (31-2-1, 18 KO) weighed in at 146 pounds, with Kamegai (24-1, 21 KO) at 146¾ for their 12-round main event, which will be Guerrero's first fight since a one-sided decision loss to Floyd Mayweather in May 2013. The 31-year-old Guerrero figures to be in for a tune-up bout with this one, but we've seen a few tune-ups turn out to be competitive affairs and upsets this year.
In another welterweight fight set for 10 rounds, Devon Alexander weighed in at 148¼ with Jesus Soto Karass at 148, both given a little leeway in the non-title fight. Alexander (25-2, 14 KO) is looking to bounce back from a loss to Shawn Porter in December, while Soto Karass (28-9-3, 18 KO) is trying to rebound from a TKO-9 loss to Keith Thurman, also in December.
Gary Russell Jr (24-0, 14 KO) and Vasyl Lomachenko (1-1, 1 KO) will meet for the vacant WBO featherweight title, which Lomachenko narrowly missed winning in March when he dropped a split decision to Orlando Salido, in a fight where Salido missed weight. Both Russell and Lomachenko weighed in at 125½ for what is the true main event in the minds of most diehard fight fans.
