Jonathan Osorio struck just after half-time for the MLS club, but Defoe hit his first two goals of pre-season later in the half to give Sunderland victory – the first of their North American tour following defeats to Sacramento Republic and Club de Futbol Pachuca last week.
Defoe joined the Black Cats in January after spending just a year at Toronto, and scored four goals in 17 games as Dick Advocaat’s team avoided relegation from the Premier League.
“I feel like I needed the pre-season,” Defoe told the Sunderland Echo. “Today was the sharpest I felt in a long time.
“It’s still a case of getting our fitness up. But at the same time, you want to be sharp, score goals and win the games.
“We’ve got a couple of weeks until the season starts and we’ve got two more pre-season games. By the time the season starts, hopefully we’ll be ready.”
