Washington’s basketball franchise hadn’t experienced the pleasure of winning a second-round playoff game since the Reagan administration. It hadn’t won a game of any kind in Indiana since George W. Bush was in office. But when the Wizards arrived at Bankers Life Fieldhouse on Monday for their Eastern Conference semifinal game against the Indiana Pacers, they were more concerned with making history than allowing past failures to haunt them.

The Wizards were rested and ready for the top-seeded Pacers, jumped out to an early double-digit lead and held on for a 102-96 victory that scratched two glaring and embarrassing marks from the to-do list. Bradley Beal scored a game-high 25 points and Trevor Ariza had 22 as the Wizards won their fourth straight road game in the playoffs and took a one-game-to-none lead in this best-of-seven series.

With each postseason win, before each stunned silent crowd, the Wizards continue to believe that this run doesn’t have to end anytime soon.

“Our goal from the beginning of training camp was just to make the playoffs, but after a while, you kind of build a little confidence and feel like you belong,” John Wall said after scoring 13 points and handing out nine assists for a team that has won nine of its past 10 games.

Washington won a second-round playoff game for the first time since 1982 — before all but three members of the team were born — and snapped a 12-game losing streak in Indiana, dating from April 11, 2007.

“We know this is a tough building to play in. We haven’t won here in a while. Why wouldn’t this be the best time to come in here and get a win in the playoffs,” Ariza said after going 6 for 6 from long distance to match his own franchise playoff record for three-pointers in a game. He also broke the previous record of four without a miss, set by Kevin Grevey for the Bullets in 1982.

Ariza helped limit Pacers all-star forward Paul George to just 18 points on 4-for-17 shooting.
