Millville junior-middleweight Thomas LaManna remained undefeated with a four-round unanimous decision over Josh Williams at the Robert Treat Hotel in Newark on Wednesday night.

LaManna, a 19-year-old recent graduate of Millville High School, improved to 5-0 with 3 KOs. Williams, from Sheridan, Ark., fell to 3-3.

Boxing returns to Atlantic City on Oct. 1, when WBC/WBO middleweight champion Sergio Martinez (47-2-2, 26 KOs) defends his titles against Darren Barker (23-0, 14 KOs) at Boardwalk Hall.

Martinez will be making his fourth appearance in Atlantic City in the last two years. In his last outing, he scored a spectacular, second-round KO over Paul Williams on Nov. 20, 2010.
