Top seed and tournamnet favourite - Roger Federer needed just 39 minutes to dismantle Mischa Zverev 6-0,6-0 to storm into the semifinals of the Gerry Weber Open, an ATP 250 event, in Halle, Germany. This was the second instance where Federer secured a double-bagel over any of his counterparts.

The Swiss ace made a clinical start by breaking Zverev's serve in no time. He then held his serve twice and broke Zverev two times thereafter to grab the first set 6-0. After the beatdown in the opening set, Federer didn't allow his 156th ranked counterpart to gain control.

He convereted 3/5 break points opportunites to bag the second set 6-0, and booked himself a semifinal spot. The maestro won 54/76 (71%) of the total match points and bagged 83% of his second serve points against 31% of Zverev, which helped him record a crushing victory.

The 17-time grand slam winner will meet the winner between Tommy Haas and Gael Monfils for a place in the summit clash.
