The American only just managed to hold onto his crown in California, two judges scoring the fight 116-112 and 115-113 in his favour, with the other giving it to Ugas 117-111.
Porter, 31, struggled to make weight and he was below his best against challenger Ugas.
"I think we won the majority of the rounds. I would not have given Ugas very many," he said after his win.
Ugas, the 32-year-old Cuban coming off eight straight wins, rattled Porter and only just fell short of an upset win.
