LOS ANGELES — Victor Wembanyama, who has been sidelined with a calf strain since November 15, showed positive signs during pregame warm-ups before the Spurs’ victory over the Lakers, raising hopes for his return in the NBA Cup semifinals against the Thunder. Spurs coach Mitch Johnson noted Wemby had a strong day of practice, and the team, bolstered by key guard performances, has thrived in his absence, advancing to the semifinals with a 9-3 record.
