STOCKTON, October 7, 2017
The semi-finals at the $100,000 Stockton Challenger are set. Third seed Michael Mmoh remains the highest ranked player left in the singles draw. The World No. 159 from Florida benefited from the retirement of Russian qualifier Dmitry Tursonov due to a left harmstring injury leading 6-3 on Friday.
Mmoh will take on in-form Briton Cameron Norrie next. The 22-year-old knocked out second favourite Tennys Sandgren from the United States 6-3, 7-6. Norrie sent down five aces, winning 78 per cent of his first service points to prevail after one hour and 36 minutes.
Darian King beat fourth-seeded US-American Stefan Kozlov 6-4, 6-4. The tournament’s number six from Barbados won 54 per cent of the total points played to secure victory in one hour and 26 minutes. King will next face Tim Smyczek. The 29-year-old from Tampa edged past #NextGenATP player Elias Ymer of Sweden 6-4, 6-4. The encounter lasted one hour and 27 minutes.
