Fifth seed Philipp Kohlschreiber was sent packing at the MercedesCup on Tuesday as he went down to Denis Istomin.
It was a tough break for the German as he didn’t lose his serve during a match that was interrupted by rain with the man from Uzbekistan winning the two tie-breakers 7-6 (7-2), 7-6 (7-3).
Istomin will face another German in Florian Mayer in the second round as the 34-year-old veteran beat wild card Yannick Maden 6-4, 6-1.
Meanwhile, Frenchman Gilles Simon had a relatively easy afternoon as he beat Italian Matteo Viola 6-0, 6-3 and he will face either Feliciano Lopez or Viktor Troicki in the second round with their match to be completed on Wednesday following showers.
