DETROIT — Andre Drummond had 17 points and 17 rebounds, and the Detroit Pistons beat the Portland Trail Blazers 111-91 on Monday night for their fourth straight victory.

Detroit has won three in a row with Blake Griffin in the lineup after acquiring him in a trade last week. The victory Monday pulled the Pistons back to .500 and even with Philadelphia for the final playoff spot in the Eastern Conference.

Griffin had 21 points, nine rebounds and six assists, and did a good bit of his offensive damage from the perimeter, making three 3-pointers. Anthony Tolliver added 15 points for Detroit, and Reggie Bullock and Langston Galloway contributed 13 apiece.

Damian Lillard scored 20 points and C.J. McCollum added 14 for the Blazers, who lost again after falling at the buzzer at Boston on Sunday. Portland was without Evan Turner on Monday because of a left calf injury.

Detroit led by 13 in the second quarter and was up 49-43 at halftime. The Pistons pushed the lead to double digits again in the third. A 9-0 run capped by Luke Kennard’s 3-pointer made it 75-57.

Detroit was never seriously threatened in the fourth, and the game ended with several seldom-used reserves on the court.

WIZARDS 111, PACERS 102: All-Star guard Bradley Beal scored 21 points and Kelly Oubre Jr. had 15 to help Washington win in Indianapolis.

The Wizards have won five straight overall, all without John Wall, and four in a row over the Pacers.

Bojan Bogdanovic scored 29 points for the Pacers, trying to spur a fourth-quarter rally. Joe Young added 17 as Indiana’s six-game home winning streak ended.

Without starting guards Victor Oladipo (illness) and Darren Collison (left knee surgery), the Pacers were out of sync all night.

NOTES

PACERS: Indiana will be without Darren Collison for two to three weeks after arthroscopic surgery on his left knee.

Collison suffered the injury during Saturday’s victory over Philadelphia. A subsequent MRI showed he needed surgery, and the Pacers hope to get Collison back shortly after the All-Star break.

NETS-BUCKS TRADE: Brooklyn traded center Tyler Zeller to Milwaukee for guard Rashad Vaughn and a second-round pick.

The Nets say they will get the pick this June if it falls between Nos. 31-47. If not, it will go to Brooklyn in 2020.

Zeller signed with the Nets last summer after spending the three previous seasons with Boston.

KNICKS: Guard Ron Baker will have right shoulder surgery and miss the rest of the season.
