By Dan Ambrose: Marcos Maidana (31-3, 28 KO’s) said it best himself when he said “This isn’t my weight,” in response to questioning from HBO boxing analyst Max Kellerman about his loss to Devon Alexander (23-1, 13 KO’s) last Saturday night in Saint Louis. Maidana, 28, lost by a 10 round unanimous decision and never really looked comfortable in the fight due to the extra weight he put on to fight at 147.

Maidana will now move back down to light welterweight and likely defend his WBA light welterweight title against the likes of Humberto Soto or Zab Judah in his next fight. Soto, a former WBC lightweight champion, recently moved up in weight, will be a good test for Maidana because he’ll come to fight.

At 140, Maidana’s power is much more present and he’s really hard to beat at that weight unless his opponent is allowed to grab all night long the way that Alexander was last Saturday or can shove Maidana a lot like Amir Khan did when he fought him in December 2010. Maidana may or may not keep his World Boxing Association title for long, but he’ll be one of the major players at 140 for a long time.

At 147, Maidana would have had problems against the likes of Floyd Mayweather Jr., Manny Pacquiao, Andre Berto, Kell Brook and Mike Jones. I couldn’t see Maidana beating any of them. Perhaps Berto if he could get Berto into a war, which is a good possibility. Berto doesn’t use tricks like clinching and running to win his fights. But Maidana is much better off at 140 because he’s got the power to take any fighter out in the division in a one on one fight.

Last night, Maidana fought well in the first couple of rounds but the clinching finally got to him and he was unable to do anything without the referee Steve Smoger lending a hand to keep Alexander from excessively clinching.
