The 20-year-old breezed into the last-four draw in Rome after her straight-sets victory over Zheng, winning 7-6 (7-4) 6-1.

Gauff faced just one break point throughout the match, failing to hold her serve at 5-3 up as seven-seed Zhen battled back in the first set.

Yet Gauff eased through the tie-break and never looked back from there on, teeing up a meeting with Swiatek, who overcame Madison Keys in straight sets in her quarter-final clash.

Data Debrief: Young Gauff powers on

No player has won more matches than Gauff (61) in WTA-1000 events before turning 21, since the introduction of the format in 2009, as the American moved past Caroline Wozniacki (60) with victory here.

Wozniacki (eight) is also the only player to manage more WTA-1000 semi-final appearances before her 21th birthday, with Gauff's last-four qualification here taking her onto six – one ahead of Swiatek.
