Pritchard followed up his newly reported contract extension with a stellar preseason showing.

BOSTON (AP) — Payton Pritchard scored 26 points after signing a four-year, $30 million contract extension, and the Boston Celtics beat the Philadelphia 76ers 114-106 on Sunday in the preseason opener for both teams.

Pritchard shot 9 for 14, including 6 for 11 on 3-pointers, and had four assists in 23 minutes for the Celtics.

ESPN first reported Pritchard’s extension, and the Celtics’ guard said after the game he has signed the deal.

“When I signed it, it was almost like a relief, a feeling of being secure,” Pritchard said. “That was kind of my mindset toward it. I wanted to lock something in.”

Jaylen Brown scored 19 points on 7-for-10 shooting, Kristaps Porzingis scored 17 and Jayson Tatum had 13 points and 10 rebounds for Boston.
