Open Extended ReactionsNovak Djokovic pulled out of the Italian Open on Tuesday in the midst of a three-match losing streak, shedding doubt on how well he'll be able to play at the upcoming French Open as he continues to seek a record 25th Grand Slam trophy and 100th tournament title overall. Djokovic has struggled this season, going just 12-6 and dropping his past three contests in a row -- at the Miami Open, the Monte Carlos Masters and, on Saturday, at the Madrid Open. After losing to Matteo Arnaldi 6-3, 6-4 in Spain, Djokovic said: "It's a completely different feeling from what I had in 20-plus years of professional tennis. He had to withdraw during last year's tournament at Roland Garros because of a knee injury that required surgery. Djokovic also stopped during the Australian Open this January because of a torn hamstring muscle.
