Great Britain's Olympic preparations benefited from a confidence-building second straight victory over Portugal as they got big contributions from their bench players to win 86-66.
Kyle Johnson put on a shooting clinic in the second half to rack up 21 points while Eric Boateng grabbed 11, nine of them in a two-and-a-half-minute spell at the start of the fourth quarter.
It was a much more rounded performance compared to yesterday's 83-68 victory, in which Britain had to recover from a poor first half before pulling away to record what was their first win of the summer.
"It was a far better performance today," said coach Chris Finch. "This was a continuation of the second half yesterday. We just kept building on that and today we played outstanding for four quarters.
"Everybody really made a positive contribution to the game tonight.
"We got a lot of energy from the bench. We have depth but we don't always have consistency from the bench, but tonight it was very good."
Johnson made his first seven field-goal attempts, including three big threes, and finished eight-of-10 from the field.
"I think that's my job on this team," the 23-year-old said. "I need to come off the bench and provide that energy. I think I did that today.
"Portugal were leaving me a little bit open but it felt good to knock those shots down. Credit to my team-mates for getting me open."
Portugal came out aggressively after suffering defeat yesterday, and having fallen 4-0 behind they took a 9-4 lead on Joao Gomes' three-pointer as they battled hard for offensive rebounds.
But Britain soon battled back, with Kieron Achara's three-pointer highlighting an 8-0 run to end the first quarter as they went 21-14 ahead.
The scoring streak hit 12 on a pair of free throws from Andrew Lawrence, and the big plays kept coming.
When Achara nailed another three, Britain were up 28-16, and a big dunk from Pops Mensah-Bonsu made it 37-18. Back-to-back threes from Joao Santos and Mario Fernandes kept Portugal alive, but they went in trailing 46-29 at the break. Britain continued to edge clear in the second quarter, leading by 20 when Nate Reinking's three-pointer made it 57-37, although Portugal kept fighting through the long-range shooting of Joao Santos and the third quarter ended 61-45 following Achara's third three of the game.
Boateng's spurt then helped Britain forge 70-50 ahead, and when Johnson hit the third of his four three-pointers, they were up 81-57.
Gomes led Portugal with 16 points, while Deng had 14 for GB, with Mensah-Bonsu collecting nine points, six rebounds and five steals.
"I think we played better collectively as a team," Mensah-Bonsu said. "Kyle Johnson shot the ball great and as a defence the team took a step forward. "To win like we did today gives us a lot of confidence and hopefully it carries over into the other games and the Olympics.
"We have a lot of young guys on the team and this is a pretty big stage, but if they can play like this in the Olympics that will make everybody's job easier.
"I feel like we took a step in the right direction today."
