May 18, 2013, versus Lamont Peterson
In what was his most impressive performance as a professional, Lucas Matthysse dismantled IBF 140-pound titlist Lamont Peterson in a nontitle fight with a third-round TKO. Peterson, who was coming off victories over Amir Khan and Kendall Holt, was dropped three times before referee Steve Smoger called a halt at the 2:14 mark. Matthysse improved his impressive KO percentage to 87 percent, which is higher than any of the current titleholders in the junior welterweight division, including Danny Garcia.

Both Larry Merchant and Harold Lederman, who were ringside, scored the fight for Matthysse.
