By Jason Kim: The WBA/WBO interim lightweight titles will be on the line this Saturday night when Australian Michael Katsidis (27-3, 22 KO’s) faces former two-division world champion Robert Guerrero (28-1-1, 18 KO’s) at the MGM Grand, in Las Vegas, Nevada.

This is a bad style match-up for Katsidis because of Guerrero’s superior inside fighting ability. Katsidis is coming off of a loss in which he took a lot of punishment against Juan Manuel Marquez. And now he’s facing another tough fight with Guerrero.

It’s not good timing for Katsidis. However, the money is obviously one of the reasons why Katsidis chose the tough Guerrero rather than a lesser known contender or second tier opponent. Before the loss to Marquez, Katsidis had a nice four fight winning streak going for him. He had beaten guys like Kevin Mitchell, Vincente Escobedo and Jesus Chavez.

Marquez was obviously a step too far for Katsidis, even though he found early success against Marquez when he put the Mexican fighter down with a solid left hook to the head in the 3rd. The problem is Marquez got back up and was able to dominate Katsidis the rest of the way until the fight was halted in the 9th.

Guerrero is fighting really well right now. In his last five fights, he’s beaten Efren Hinojosa, Malcolm Klassen, Roberto David Arrieta, Joel Casamayor and Escobedo. The fight where Guerrero had problems in was against Daud Cino Yordan, a young fighter from Indonesia. He was giving Guerrero a lot of problems with his head and grab technique before the fight was stopped in the 2nd because of a cut that Guerrero had suffered. Katsidis may want to study that fight because Guerrero looked out of his element against this kind of fighting and didn’t fight well at all in that bout.
