BOSTON: Grant Williams scored 27 points as the Boston Celtics eliminated the reigning champion Milwaukee Bucks on Sunday with a 109-81 game seven victory in their NBA Eastern Conference series. Celtics forward Williams produced a deadly display of scoring from three-point range at the TD Garden as Boston advanced to a conference finals showdown with the Miami Heat with a 4-3 series win. Williams’s red-hot shooting from beyond the arc was emblematic of Boston’s superiority from the field as the Bucks missed a slew of wide open looks. Bucks star Giannis Antetokounmpo finished with 25 points 20 rebounds and nine assists for Milwaukee. But the Celtics’ three-point shooting accuracy proved the difference between the two teams as Boston completed a comeback from 3-2 down in the best-of-seven series. Boston dropped 22 of 55 from downtown, in stark contrast to Milwaukee, who converted just four of 33 attempts from beyond the arc. Williams led the three-point blitzkrieg with seven threes in his 27-point haul. Jayson Tatum made five-of-nine threes to finish with 23 points.
