Bam Adebayo, Miami's second starting center on Tuesday, had 12 points and 10 rebounds. Heat star Jimmy Butler, who has demanded a trade, logged 13 points and eight assists.

Both teams shot higher than 50 percent in the first quarter, but Miami was a bit better, hitting 63.6 percent overall and 7 of 9 from 3-point range to take a 38-34 lead. Simons and Robinson each had 11 points in the period.

Miami cooled off in the second quarter, making just 30.8 percent from the floor and missing all 12 of its 3-point tries. That allowed Portland to take a 61-55 halftime lead.
