Jeff Green  scored a game-high 34 points — including a dagger 3-pointer with 45 seconds left — Paul Pierce  and Brandon Bass  each added 17, and the Kevin Garnett -less Celtics  beat the Pistons, 98-93. A 76ers loss locked the C’s into the playoffs, and a Bucks loss gave them a 2.5-game cushion over the eight seed.
WHAT WENT RIGHT
Slump busting: In an attempt to emerge from his recent shooting struggles, Avery Bradley  came out firing for the second straight game, and it’s working. He made 6-of-11 jumpers against the Timberwolves  on Monday in his highest-scoring night since March 5. And he followed that up with a 5-of-6 night on jump shots against the Pistons. In his 13 previous games, Bradley made just 22-of-70 attempts (30 percent) from beyond 10 feet.
Green Day: Once again, Green shined in his seventh straight start for the injured Garnett. He entered Wednesday’s game averaging 21.4 points (55 FG%), 5.9 rebounds, 3.6 assists, 1.4 blocks and 1.1 steals in 10 starts this season. He added six rebounds and four blocks to his 34 points on 13-of-19 shooting against the Pistons. Five-man Celtics units featuring Green were a combined plus-152, and all but one of them were in the black, according to 82games.com’s most recent updated on March 21.
Defending their honor: Somehow, the Celtics lost their two previous games to Detroit this season by a combined 35 points, allowing 103 points each time. This time around, sans Garnett, the C’s held the Pistons to 36.6 percent shooting (16.7 3P%), as pitbulls Bradley and Courtney Lee  held Detroit’s starting backcourt to 7-of-26 from the field. Of course, Bass’s 17 points on eight shots and seven boards didn’t hurt, either.
WHAT WENT WRONG
Paint job: The Pistons scored their first 12 points in the paint. Here’s how it went down: Andre Drummond from 6 feet, Greg Monroe layup, Kyle Singler layup, Drummond layup, Monroe layup and Rodney Stuckney layup. Not good. Detroit out-rebounded the C’s 8-0 on the offensive glass (Drummond 5), scored 18-of-30 first-quarter points in the key and took a five-point edge on Monroe’s eight points, four rebounds and three assists. Also not good. When all was said and done, Detroit outscored the Celtics 58-28 in the paint.
Sloppy second half: With 3:49 left in the third quarter, the Celtics took a 74-56 lead on Chris Wilcox ‘s one and only bucket. That’s the good news. The bad: The Pistons closed the third quarter on an 11-0 run thanks to nine points from Monroe and Jonas Jerebko. When Jerebko (19 points) converted a 3-point play to start the fourth quarter, the C’s 18-point lead was trimmed to four, and the teams had themselves a ballgame.
Extra chances: The Celtics shot 50.7 percent from the field. The Pistons shot 36.6 percent. So, how in the heck was it a three-point game midway through the fourth quarter? Turnovers, for one. The C’s committed 16 of them, leading to 20 Detroit points. And offensive rebounds. The Pistons grabbed almost as many offensive boards (25) as defensive (27), giving the visitors 22 more shots for the game.
