Kvitova still has not regained full strength in her left hand, the one she uses to swing a tennis racket _ and the one that was stabbed by an attacker at her home in December. The two-time Wimbledon champion is simply thrilled to be back on tour, and she's seen as a serious title contender on the grass on which she excels.(AP Photo/Sang Tan, File)
