As well as Jannik Sinner is playing at Wimbledon, he doesn't appear to need much in the way of help. Still, he got some Saturday when his opponent, Pedro Martinez, was dealing with a problematic shoulder and often put in first serves at so-so speeds.

Jannik gave away only 17 games in nine sets, providing stunning efficiency and matching a remarkable Wimbledon record held by Jan Kodes since 1972. Reach, power, speed, strength - Jannik has it all 👏 #Wimbledon | @janniksin pic.twitter.com/K8byPKbLck
