MICHIGAN (Reuters) - Reggie Jackson poured in 39 points, one shy of his career high, and the Detroit Pistons clinched their first play-off berth in seven seasons by topping the Washington Wizards 112-99.

Tobias Harris had 17 points and pulled down nine rebounds for Detroit (43-37), which gave away a 19-point lead but recovered to end the longest play-off drought in the Eastern Conference.

Kentavious Caldwell-Pope tossed in 14 points and Marcus Morris contributed 13 for the Pistons, who will make their first post-season appearance since the 2008-09 season.

All-Star Andre Drummond, who scored his 4,000th career point, was limited to eight points and six rebounds.

Markieff Morris' 29 points led Washington (38-41), which was eliminated from play-off contention. Bradley Beal supplied 25 points for the Wizards, who played without All-Star point guard John Wall. He sat out for the second straight night with a sore right knee.

At the Amway Centre in Orlando, Nikola Vucevic scored 29 points and Evan Fournier had 28 to lead Orlando past Miami 112-109.

The Magic (34-45) snapped the Heat's two-game winning streak and hurt the Heat's efforts to secure home-court advantage in the first round of the play-offs.
