BOSTON — The Boston Celtics, continuing their quest to finish third in the Eastern Conference, set up a Saturday night showdown with the Hawks in Atlanta by hammering the Milwaukee Bucks 124-109 on Friday night.

The win, their fourth straight and eighth in the last 10 games, moved the Celtics, who got a career high-matching 26 points off the bench from Tyler Zeller, into a tie with the Hawks for third place in the conference. The Miami Heat and Charlotte Hornets are both a game behind — and the Celtics (47-32) host Charlotte on Monday and Miami on Wednesday.

Finishing third or fourth in the conference would give the Celtics the home-court advantage in the playoffs. How important is that? The Celtics have won 18 of their last 20 at TD Garden.

Boston trailed by 11 in the first quarter but had romped all the way to a 21-point lead at the end of the third.

Zeller led the Celtics, while Isaiah Thomas scored 20 and was allowed to rest in the fourth quarter (he played just under 25 minutes). Zeller’s offensive explosion ended Thomas’ streak of leading the team in scoring at a club-record 17 straight games.

The Celtics dished out 35 assists on 44 baskets and also got 16 points apiece from Kelly Olynyk and Avery Bradley and 15 from Jared Sullinger. Marcus Smart and Evan Turner dished out nine assists apiece off the bench.

Zeller, who also scored 26 points on March 26, 2015, missed his last two shots, finishing 9-of-15 from the floor.

The Bucks’ Giannis Antetokounmpo continued his recent torrid offense by scoring 17 of his 27 points in the first quarter but fell victim to second-half foul trouble but still led all scorers. Jabari Parker scored 18 points, Miles Plumlee had 16 and Tyler Ennis had nine assists.

The Bucks, playing without injured leading scorer Khris Middleton, rode Antetokounmpo to their 11-point lead. Antetokounmpo had 17 points, four rebounds and three assists by the end of the quarter but the Celtics had trimmed the lead to five and then took advantage of his rest in the second quarter.

The home team rallied, took the lead at 40-39 and had it up to eight with 1:02 left in the half. The lead was five and the Celtics had to go full-court in the final 2.5 seconds — but Smart, a true sparkplug in the second quarter after getting four stitches for a cut at the end of the previous game, hit Sullinger with a home-run pass, Sullinger laying the ball in with a half-second left to give Smart his seventh assist in 16 minutes of first-half play.

Pistons 112, Wizards 99

AUBURN HILLS, Mich. — Reggie Jackson poured in 39 points, one shy of his career high, and the Detroit Pistons clinched their first playoff berth in seven seasons by topping the Washington Wizards 112-99 on Friday at The Palace.

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 playoff 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 postseason 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 the Wizards (38-41), who were eliminated from playoff contention. Bradley Beal supplied 25 points for Washington, which played without All-Star point guard John Wall. He sat out for the second straight night with a sore right knee.

Marcus Morris scored six points in a 39-second span, capping off a 13-4 Pistons spurt that gave them an 81-65 lead midway through the third quarter.

Marcus’ brother carried the Wizards back in the game.

Markieff Morris, who had five first-half points, scored 20 in the quarter. He capped off his flurry with a heave beyond midcourt that swished through as the buzzer sounded to cut Detroit’s advantage to 86-84.

Markieff’s free throws in the opening minute of the fourth tied it. His dunk with 10:04 left put Washington on top 89-88.
