Castle was back in the Spurs’ lineup after missing two games with a hip injury, and he played 23 minutes. There was an injury scare during the first half, as the reigning Rookie of the Year took an inadvertent Jaime Jaquez Jr. knee to the head, but he returned to action after a short stint on the bench. And with the Spurs winning by 25 points, there was little need for the team to have Castle play starters’ minutes in his first game back. Harrison Barnes returned to the bench on Monday, finishing with 13 points, three rebounds, one assist, two steals and four three-pointers.
