The screw holding the net in place at the Australian Open's main stadium got jarred loose during defending champion Jannik Sinner's fourth-round match against Holger Rune on Monday, delaying play for about 20 minutes early in the fourth set.
The No. 1-ranked Sinner, who is the defending champion at Melbourne Park, hit one of his booming serves into the net, shaking it. That managed to inadvertently undo the metal piece that hooks into the bottom of the black webbing that separates players on a tennis court, then is rotated to screw into the blue-painted surface.
