Cilic’s form at 2010 Australian Open?

Question

It’s been a mixed bag so far, and after watching 17-year-old Bernard Tomic push Marin Cilic to five of the least entertaining sets of the tournament in the second round, the 14th seeded Croat has bounced back to defeat 19th seed Stanislas Wawrinka and then fourth seed Juan Martin del Potro to find himself in the quarter-finals.
