Isaiah Thomas, Kelly Olynyk lifts Celtics over Wizards in Game 7

BOSTON – Isaiah Thomas said he didn't feel any pressure entering the first Game 7 of his career.

His play backed up his confidence and with the help of Kelly Olynyk and the Boston bench, Thomas earned the biggest win of his career.

Thomas scored 29 points and had 12 assists, Olynyk scored a career-playoff high 26 points and the Celtics used a big fourth quarter to outlast Washington 115-105 in Game 7 of the Eastern Conference semifinals Monday night.

"I knew it would be a big time game tonight. I knew it wouldn't be easy at all," Thomas said. "And we came out on top."

Led by Olynyk the Celtics got a huge lift from their bench, outscoring their Wizards counterparts 48-5.

"He just made shots," Washington's Marcin Gortat said of Olynyk. "He was the difference today — a huge difference."

Boston connected on 11 three-pointers, including eight of 13 in the second half.

It serves as the ultimate validation for a team that many felt was unworthy of the conference's top seed. It also marked the latest big performance by Thomas, who credited his teammates for the victory.

''That says a lot about the team we are and we believe in each other," Thomas said. "The game wasn't always what we wanted it to be and it wasn't a perfect game. But we kept going and stayed the course."

Bradley Beal led the Wizards — who were playing in their first Game 7 since 1979 — with 38 points, including 24 in the second half.

"I don't care how well I played," Beal said. "I don't care if I played bad. The end result … the only thing that matters is getting a win."

The Wizards got within four with six minutes to go but were outscored 14-4 down the stretch.
