SACRAMENTO, California — Instead of dwelling on his mistake that let Sacramento tie the game in the closing seconds, Gordon Hayward made it moot. Hayward made up for a costly foul by hitting a tiebreaking shot with 2 seconds to play that helped the Boston Celtics overcome the absence of injured star Kyrie Irving in a 111-109 victory over the Kings on Wednesday night. Hayward fouled Buddy Hield on a 3-point attempt with 7.6 seconds left, allowing Sacramento to pull even.
