Robert “The Ghost” Guerrero will fight for the first time in 13 months Saturday when he takes on Yoshihiro Kamegai (24-1-1, 21 KOs) of Japan in the welterweight main event at StubHub Center (on Showtime).

Guerrero (31-2-1, 18 KOs), of Gilroy, has been inactive this long in part because he had contractual hassles with his promoter, Oscar De La Hoya of Golden Boy Promotions. The sides didn’t want to touch much on that during a conference call Tuesday – obviously, things are settled enough to where Guerrero is going to fight – but Guerrero did talk about many other things. Included was his one-sided decision loss to Floyd Mayweather Jr. on May 4, 2013 in Las Vegas.

“To bounce back, it wasn’t tough at all,” said Guerrero, when asked about the psychological aspect of getting over his first loss in 7 1/2 years. “You’ve gotta learn from experiences like that. I lost to be the best fighter in the world. You want to get better, you want to get stronger, you want to get faster. It really lit a fire under me to become a better fighter. I can’t wait to get out there and fight.”
