MELBOURNE, Australia (AP) — Ben Shelton's Australian Open quarterfinal foe, Lorenzo Sonego, produced the shot of the tournament — diving to his left for a volley with so much spin that the ball bounced on one side of the net, then floated back over to the other — but it was the American who ended up with the victory Wednesday.

Ben Shelton battled to a four-set win over Lorenzo Sonego to reach his second grand slam semi-final. The big-serving American made his breakthrough at the Australian Open two years ago with a run to the quarter-finals on his debut before bettering that at the US Open.

All-action Ben Shelton battled past stubborn Italian Lorenzo Sonego 6-4, 7-5, 4-6, 7-6 (7/4) on Wednesday to reach his first Australian Open semi-final.
