All-in-all, the Kelly Pavlik vs Sergio Martinez undercard had plenty of good stuff.  It was a step forward for many of boxing’s future stars as well as some current fighters.  Kudos to Top Rank and Bob Arum for presenting a very good undercard.

In the opener, Dominic Guinn scored a 7th round TKO over Terrell Nelson.  The fight had a good pace for heavyweights and Guinn landed the big blows when he needed to.  Guinn improved to 33-6-1 while Nelson fell to 8-10 as a pro.

A battle of 142-pound fighters saw Vincent Arroyo hand Jeremy Bryan his first pro defeat in 14 fights.  Arroyo had a mad flurry in the fourth round knocking Bryan down.  The ref could have counted to 40 instead of 10, either way, Arroyo improved to 10-1 with seven KO’s.

Ronald Hearns, son of Thomas “Hitman” Hearns ran his record to 25-1 with an impressive first-round TKO over Delray Raines.

Chris Hazimihalis then took out Ramon Ellis to extend his unbeaten streak to 2-0.  After his debut in December, when he admittedly came out nervous before unwinding, Hazimihalis came out full steam ahead in picking up the impressive win.

Undefeated Chris Jones (21-0) looked impressive in carving up Hector Munoz (18-3-1) in five rounds.  Jones claimed the NABA Welterweight Title with the win in front of a very partial Philadelphia-based crowd.  Jones tagged Munoz frequently and when he wanted to in posting the impressive TKO victory.

In a battle of 160-pounders, Josh Snyder challenged Matt Korobov of Russia.  Snyder gave Korobov everything he had and both fighters landed several big shots in a very entertaining contest.  In the end, the judges awarded a unanimous decision to Korobov who ran his perfect record to 11-0.

The last fight before the main event featured another local favorite in Glen Tapia as he faced James “Shotgun” Winchester in a 152-pound battle.  Tapia bloodied Winchester with some big shots in the second round.  Winchester wasted more energy taunting than fighting at various stages of the contest.  All three judges scored the four-round fight 40-35 in favor of Tapia who jumped to 6-0 with the win.
