There wasn't a single break of serve all game, but Karlovic had the edge in both tie-breakers, clinching them 9-7 and 7-4 to complete victory in one hour and 47 minutes.
The two men were serving so well that there was just a single break point in the whole match. It was also a set point for Karlovic at 5-4 in the first set, but he could not take it.
It did not end up costing the Croatian as he came out on top in both tie-breakers to reach round two in Doha.
