Input: Melbourne (AFP) â  Croatiaâs Marin Cilic  won  his  100th Grand Slam match as  he  mastered Spainâs Pablo Carreno Busta in four sets to reach the quarter-finals of the Australian Open on Sunday.
 Cilic  reached the last eight in Melbourne for the second time and also claimed  his  11th Slam quarter-final to equal Goran Ivanisevicâs record for appearances at that stage of the majors by a Croatian man.
âThere were lots of ups and downs and Pablo gave me a lot of trouble in that third set where he was twice a break up and it was difficult mentally â  Cilic  said.
â We  had a lot of tough rallies in difficult humid conditions so I was really glad how I stayed in there mentally and really played well in the end.â
 Cilic  served 20 aces  broke serve six times and made a total of 73 winners as well as winning the majority of the long rallies.
âThatâs my style of play. Pablo is extremely solid from the back of the court and has great shots both on the forehand and backhand and  he  was serving really good today â  Cilic  said.
 Cilic  said  he  faced a big challenge against either Nadal or Schwartzman in the quarter-finals.
âI have played great tennis from the first round against tough opponents and now I am really looking to the next match  it will be definitely be a big challenge â  he  said.
