ODENSE - India's Saina Nehwal is showing signs of fulfilling the potential that earned her a recent $7.4 million deal by reaching the Denmark Open badminton final after her world No. 1-ranked opponent retired with a knee injury. The 22-year-old world No. 4 was leading 21-12, 12-7 against Wang Yihan Saturday when her Chinese opponent limped off the court at Odense. Pitted against the woman who had thrashed her 21-13 21-13 in the Olympic semifinals in London, Nehwal proved too strong for Wang. Nehwal will meet world No. 7 Juliane Schenk of Germany who downed Jiang Yanjiao 13-21, 21-14, 21-15 in final. — Reuters
