Andrea Petkovic was visibly riled by the quality of officiating during her 7-5, 6-3 loss to Zarina Diyas at the Dubai Tennis Championships. With the score poised at 5-6 in the first set, the German let a deep shot bounce as it landed clearly beyond the baseline. Strangely, however, the decision given was that the ball was in and Petkovic crashed to her knees in frustration, banging her hands while screaming and pleading to the umpire, who remained unmoved by her protest. Andrea Petkovic cannot believe it as an incorrect decision is given against her The German points out that the ball she let bounce had clearly crossed the baseline
