Dwane Casey altered the Pistons’ playing rotation significantly against the Milwaukee Bucks. It was for naught. The Eastern Conference-leading Bucks, with Pistons owner Tom Gores seated courtside, easily fended off the Pistons with a 115-105 victory at Little Caesars Arena on Tuesday night. Reggie Jackson tied a season high with 25 points, but the Pistons (21-28) fell three games behind the Charlotte Hornets for the Eastern Conference’s eighth and final playoff spot. Giannis Antetokounmpo scored 21 points and point guard Eric Bledsoe scored 20 as the Bucks (36-13) swept the season series over the Pistons, 4-0, for the first time ever. The Bucks shot 13-for-32 from 3-point range (40.6 percent). The Bucks scored 26 points off 12 Pistons turnovers. Blake Griffin scored 18 points, only his second game with fewer than 20 points this month. Andre Drummond added 20 points and grabbed 13 rebounds. The Pistons were without Reggie Bullock (left ankle sprain), forcing Casey to juggle the lineup. He started Glenn Robinson III and Langston Galloway, sending Bruce Brown to the bench as the backup point guard. Robinson and Galloway combined for two points in 32 minutes. Starting Galloway and Robinson signaled a significant rotational change. Robinson had played less than 30 total minutes since Dec. 10, so it was a stunner to see him receive his first start since that night at Philadelphia. And he struggled mightily, going scoreless in 12 minutes. Early in the second half, he drove into the paint with no plan and committed a careless turnover. That was the last the game saw of Robinson. Brown was the initial backup point guard, but looked tentative. Jose Calderon was the backup point guard in the second half, but only played three minutes. Contact Vince Ellis: email@example.com.
