“What was exciting to me was the way we played defensively in the second half, and specifically, in the fourth quarter,” Silver Stars coach Dan Hughes said. “(It was) some of the best defense we have played all year against a team that is a good basketball team.”

San Antonio also opened strongly, scoring the first nine points of the game on a 3-pointer by Christon and three straight baskets by Robinson.
“We needed a spark,” Robinson said. “We’ve kind of started games a little flat so I wanted to make sure that we didn’t. I wanted to make sure that I came out aggressive.”
It was the largest advantage either team would have in the first half.
Christon made two more 3s to extend San Antonio’s lead to 16-10 with 2 minutes left in the first. New York scored the final two baskets of the quarter to pull within 16-14 entering the second.
