The Celtics struggled and stumbled through most of regulation against the Washington Wizards Wednesday night at TD Garden. But they got their act together in overtime for a 100-94 victory, their second over the Wizards in four days.

“Well, we won the game and, right now, that’s the type of team we are,” coach Doc Rivers said. “We’re not playing great. It’s good to win a game like that. We’ve won two like that.”
