Lester Martinez will already enter the ring as the shorter fighter.

He is also the lighter of the two unbeaten super middleweights who will headline Wednesday's ProBox TV show.

Guatemala's Martinez (18-0, 15 knockouts) was a trim and fit 167 pounds, while Joeshon James (9-0-2, 5 KOs) was 167.6 pounds. The two will meet in a ten-round regional title fight from ProBox TV Events Center in Plant City, Florida.

Martinez isThe Ring's No. 8-rated super middleweight contender. The undefeated 28-year-old drew accolades for his June 28 points win over Carlos Gongora in Washington, D.C. It snapped a five-fight knockout streak, but Martinez won nearly every round versus the highly-regarded contender.

Meanwhile, James is once again prepared to play the spoiler role.

The 26-year-old from Sacramento, California has grown accustomed to upsetting the apple cart. James went 2-0-2 versus four consecutive unbeaten opponents. Most notably, he scored a stunning first-round knockout of David Stevens, who was 13-0 when they met last Oct. 21 in Inglewood, California.

James most recently defeated Vaughn Alexander (18-8-1 at the time) atop a Feb. 16 ProBox show in Plant City.
