With five players sidelined by injury or illness, Washington Wizards Coach Randy Wittman stressed the term “opportunity” when talking prior to Monday’s contest against the Memphis Grizzlies.

While the lengthy injury report opened playing time for several seldom-used reserves, it was John Wall who seized the moment.

Wall scored a career-high 47 points to lead the undermanned Wizards past the Grizzlies, 107-94, at Verizon Center. The playmaking point guard also added a career-best 19 points at the foul line, although afterward his focus was on the five free throws he didn’t make.

“I could have 52 if I had made my free throws,” said Wall, whose output ranks as the third-highest point total by an NBA player this season. “But so be it.”

Emeka Okafor picked up what little slack Wall left at the line, tallying 21 points and nine rebounds to give the Wizards a necessary post presence against one of the league’s most physical teams.

The win marks Washington’s sixth straight at home as well as its first victory against Memphis since 2010.

Signs of Wall’s big night surfaced in warmups, when he wowed the crowd with a one-handed, 360-degree dunk, showing few signs of any lingering fatigue from the Wizards’ recent four-game road trip.

He continued to assert himself once the game started. He made three consecutive jump shots that put the Wizards up 12-4 midway through the first quarter.

“I thought the first five minutes were going to be key,” Wittman said. “If we could come out in the first five minutes and establish both ends of the floor a little bit, I thought it would help our psyche a little bit coming into this and it really did that.”
