With rain coming down outside, Novak Djokovic warmed up for the Wimbledon semifinals on Friday by getting some practice time under the roof on No. 1 Court.
The seven-time champion will face Jannik Sinner on Centre Court later in the day. Djokovic is looking to win a 24th major title while Sinner, an eighth-seeded Italian, is trying to reach a Grand Slam final for the first time.
