Oosthuizen vs Gonzales by Clarence George on May 5, 2013 (boxing.com)

Thomas Oosthuizen vs Brandon Gonzales is on the under card of the Gennady Golovkin-Matthew Macklin main even, the fights to take place on June 29 at the MGM Grand, Foxwoods Resort, in Mashantucket, Connecticut. The scheduled 12-rounder is for Oosthuizen's IBO super middleweight championship.

Oosthuizen (21-0-1, 13 KO's), who turned 25 last month, has been fighting pro since 2008. Always victorious, save for a draw against Isaac Chilemba three years ago, the South African southpaw won the vacant title by stopping Evert Bravo by ninth-round TKO in 2011. Next month's bout will be his seventh title defense and his first fight this year.

"Tommy Gun" fought four times in 2012, stopping Serge Yannick by sixth-round TKO in March, and beating Marcus Johnson in April, Rowland Bryant in August, and Fulgencio Zuniga in November, all by unanimous decision.

Gonzales (17-0, 1 NC, 10 KO's), who'll turn 29 this month, was America's top-ranked amateur middleweight in 2005. Undefeated since turning pro in 2007, "Flawless" last fought this January, beating Don Mouton by unanimous decision. He fought only twice last year, defeating Elie Augustama by unanimous decision in June. Gonzales had one no-contest, against Daniel Stanislavjevic in 2008.

Born in Portland, Oregon, and currently a resident of Sacramento, California, Gonzales had been scheduled to fight New York hard boy Will Rosinsky in Shelton, Washington, on April 12, but cancelled, ostensibly because of a torn hamstring. "They mentioned rescheduling for May", said a disappointed Rosinsky. "We'll see." The bout with Rosinsky is off and the one with Oosthuizen is on.

Was Gonzales more opportunistic than injured, leaping, despite the torn hamstring, at the chance to face a more highly regarded opponent? If so, he may very well pay a stiff price for his cunning. While he had a shot at beating Rosinsky, his chances of defeating Oosthuizen are just this side of nil. Though not quite in the same league as Andre Ward, Carl Froch, or Mikkel Kessler, "Tommy Gun" is nonetheless one of the best super middleweights in the world today.

Good night, Irene, and good morning, nurse: Gonzales has bitten off a lot more than he can chew - a bit of South African hardtack by the name of Thomas Oosthuizen.
