Djokovic, Ferrer and Tipsarevic tipped for US Open quarter finals

Spots in the quarter finals are up for grabs in the US Open and Novak Djokovic has been blazing his way through the draw thus far.

He is expected to make Stanislas Wawrinka his next victim, while David Ferrer and Janko Tipsarevic are others that are expected to make light work of their fourth round matches.

Novak Djokovic v Stanislas Wawrinka: Under 30.5 games @ 5/6

Djokovic has a major point to prove and has been dominating everyone in the current hard court season who he has faced other than Roger Federer.

Wawrinka is talented, but with Djokovic dropping just 14 games in his opening three US Open victories, another comfortable victory should follow.

Djokovic has beaten Wawrinka in their last nine encounters dating back to 2006 and can triumph here by a margin of 6-4, 6-4, 6-4 at worst.

Juan Martin del Potro v Andy Roddick: Over 35.5 games @ 1/2

As long as Del Potro plays to 80 per cent of his capacity, he should win, given his better movement and superior ground strokes.

However, defeat for Roddick will bring his retirement and so he is almost certain to attack at every opportunity and go for his shots.

This should at worst lead to three close sets, while Roddick is more than capable of claiming a set if returning deep and taking his chances of coming into the net.

Roddick also beat Del Potro last year on his home patch in Memphis, but the Argentine has clearly improved since.

Janko Tipsarevic (-3.5 games) to beat Philipp Kohlscreiber @ 4/6

The head-to-head record sees the pair evenly matched at 2-2, but Kohlscreiber has been involved in back-to-back five-setters at Flushing Meadow and this will now take its toll.

He was certainly given the run around by John Isner in a late-night classic and Tipsarevic has the aggression to keep the German on the run again.

Tipsarevic may well win this in straight sets at 2/1, but even if he triumphs in four he should still cover the handicap and this is the safer bet.

David Ferrer to beat Richard Gasquet 3-0 @ 13/8

Unbelievably, all eight previous meetings between the pair have been won in straight sets, with Ferrer successful on seven of these occasions.

One of these also came at the other hard court Grand Slam of 2012, when Ferrer triumphed 6-4, 6-4, 6-1 at the Australian Open.

Gasquet is arguably playing better now than he was in January, but Ferrer’s grinding nature can see him progress in straight sets to the quarter finals.
