Veteran Kohlschreiber upsets youngster Zverev to reach US Open 4th round

New York : German veteran Philipp Kohlschreiber delivered the shock of the mens draw so far after beating his fourth-seeded compatriot Alexander Zverev 6-7 (1), 6-4, 6-1, 6-3 in their third round tie at the US Open at Flushing Meadows.

The world number 34, who is making his 16th appearance at the US Open, demonstrated better focus and efficiency on Saturday, particularly after having secured the crucial break of serve in the second set, which Kohlschreiber won 6-4.

The first set had been decided by a tiebreaker in what was an even opening to the match, but Kohlschreiber dominated the proceedings after that second set, as the younger Zverev had no answer to the veteran's accuracy, reports Efe news.

Kohlschreiber moves on to the Round of 16, where he will face Japan's Kei Nishikori.
