Second-seeded Simona Halep and former world No. 1 Caroline Wozniacki secured berths in Saturday's semifinals at the Porsche Tennis Grand Prix.
The Romanian star Halep, who will replace Maria Sharapova as the new world No. 2 on Monday, got past Italian fellow French Open runner-up Sara Errani 6-4, 6-4 on the indoor clay at Porsche Arena.
The hot Halep has won 16 of her last 17 matches, including recent titles in Dubai and Indian Wells.
Her semifinal opponent will be the Wozniacki, who blitzed eighth-seeded Spaniard Carla Suarez Navarro 6-0, 6-3 on Day 5. Wozniacki was a Stuttgart runner-up back in 2011.
The 2014 Roland Garros runner-up Halep is 2-1 against last year's U.S. Open runner-up Wozniacki, including a semifinal win in Dubai in February.
The 2015 Stuttgart champ will earn $108,000 and a new Porsche 911 Carrera sports car.
