SAN FRANCISCO (AP) — Klay Thompson scored 21 points, Stephen Curry had 18 and the Golden State Warriors returned from a tough trip to beat the Detroit Pistons 102-86. Curry was back after a one-game absence. He shot 6 for 11 with four 3-pointers and added eight assists. He fell on his right hand during a win at Chicago on Friday, then missed Sunday’s 119-99 loss at Minnesota. Andrew Wiggins scored 19 points for the Warriors, who were coming off a 1-3 road stretch. Thompson found a groove in his second home game since returning from two devastating injuries and surgeries that cost him more than 2 1/2 years.
