Cilic has lost a Slam QF or SF three times. In all of the said occasions, he was up at least a set and a break (two breaks this year vs Murray) and then went on to lose in 4 - Delpo USO 2009 QF, Murray AO 2010 SF, Murray USO QF.
He's remarkably consistent in the way he implodes deep in Slams
Well he lost to the winner twice. In 2009 he'd just beaten Murray, in 2010 he was tired after a trio of long matches and in 2012, well 2012 was a classic moment, I laughed for a few minutes after the result. Cilic probably did too after reciving a £200,000 cheque from the czech after.
He's a average player with the mental ability of a 2 year old. The only wins he has are after the opposition assults the line judge.
