Citizens Business Bank Arena, Ontario, California - Robert Guerrero (31-1-1, 18KOs) proved that he's a full fledged welterweight and certainly a player at 147-pounds, as he scored two knockdowns to win a twelve round unanimous decision over Andre Berto (28-2, 22KOs) to retain the WBC interim-welterweight title. The scores were 116-110 across the board. Photos by German Villasenor.
