Gerry Weber Open, Halle
 Alexander Zverev (GER) vs.  Benjamin Becker (GER)
Zverev won their one previous encounter; however, Becker took the first set, so Zverev knew this was potentially a dangerous opponent. Becker took the initiative and looked poised to take the first set with a two break lead; yet, he failed to remember that Zverev is young and full of confidence. In addition, Zverev has the weapons off the ground and a huge serve. Zverev patiently worked his way back into the first set, cutting down on his errors and playing with focus. He broke back to even the match and then broke again to steal the first set.
Becker seemed to lose his belief after he lost the first set. He called for the trainer early in the second set but continued to play and was broken in his first service game. Becker tried to play through the pain by going for all his shots, but Zverev withstood the attack and kept playing error free tennis. 5-7, 0-3 down, Becker went to the changeover and was evaluated by the trainer. Becker retired with a back injury and Zverev won 7-5, 3-0 (RET). Zverev will play Marcos Baghdatis next; he lost their only encounter last year. Can Zverev turn the tables on Baghdatis?
 Gilles Simon (FRA) vs.  Kyle Edmund (GBR)
Simon won their only previous encounter on grass in 2013. Yet, the young Brit had no desire of leaving early and he dug his heels in and won the first set. Simon fought back in the second but could not sustain the level of play required to quell Edmund’s fight. Edmund won 6-4, 3-6, 6-1. Can Edmund continue his inspired tennis and take out another Frenchman to get to the quarterfinals?
