MIAMI — The Miami Heat were a worthy warmup act for Dwyane Wade’s jersey retirement Saturday night, breaking a 23-year-old franchise record for points in the first half en route to a 124-105 victory over the Cleveland Cavaliers.

Miami shot 77 percent in the first half and then turned the stage over to Wade, whose No. 3 jersey was hoisted to the rafters at halftime. The ceremony was part of a three-day celebration of Wade’s career that included three NBA titles with Miami.

Miami made its first nine shots and led 38-32 after one quarter. The Heat went 15 for 17 in the second period, outscoring the Cavs 44-20 for an 82-52 lead at the half. The Heat broke the franchise record of 75 points in the first half in November 1997 against the Los Angeles Clippers, a mark that predated Wade’s 16-year NBA career.

Cedi Osman led Cleveland with 19 points.
