Star Indian shuttler Lakshya Sen is expected to continue his purple patch, while two-time Olympic medallist PV Sindhu will strive to regain top form at the Swiss Open Super 300 tournament, beginning on Tuesday. After first-round losses at the Malaysia Super 1000 and India Super 750 earlier in the year, Sen has gained momentum. The 22-year-old enters the USD 210,000 tournament on the back of semifinal appearances at the French Open and All England Championships. The seventh-seeded Indian will open his campaign against Malaysian Leong Jun Hao and is likely to cross paths with 2021 world champion Lee Zii Jia.
