Hingis happy to be in hunt in doubles

Martina Hingis is back in the doubles semifinals of a Grand Slam for the first time since the 2002 Australian Open as she and Flavia Pennetta reached the US Open last four in their first major as a team.

Hingis, one of the greatest women's players of all time with five Grand Slam singles titles, 43 WTA Tour singles crowns and various spells atop the world rankings between 1997 and 2001, took up competitive doubles again in 2013 after six years in retirement.

An early partnership with Daniela Hantuchova failed to gel and even though she nabbed the Miami doubles with German Sabine Lisicki in March, Hingis said things did not really click until she teamed up with Pennetta, a partner she can count on in the key moments of a match.
