Bradley Beal’s face-engulfing, thick-rimmed, nerdy glasses didn’t have prescription lenses but he didn’t really need any visual assistance to recognize that he was watching history unfold on Friday night at Barclays Center in Brooklyn, N.Y. Sidelined for the second straight game with a sprained left ankle, Beal had a front-row seat as Brooklyn Nets guard Deron Williams torched the Wizards for an NBA-record nine first-half three pointers in a 95-78 victory. Williams finished with 11 three-pointers — one shy of the NBA record — and scored 42 points, the most by any Wizards opponent this season. “I’ve never seen anything like it,” Beal said. “I think we gave him a lot of easy shoots, way too many easy looks, open ones at that. He was confident, knocking them down. And when you’re in the zone like that — I’ve been in zones like that before — it’s hard to stop you. The hoop looks like an ocean, a big old basket. He definitely got the best of us.”
