Andy Roddick opened the defence of his Brisbane International title in style when he thrashed Australian wildcard Marinko Matosevic 6-3, 6-2 in Brisbane on Monday.
The second-seeded American overcame some early resistance from Matosevic to cruise away with the match and set up a second round clash with Ukraine's Alexandr Dolgopolov, who earlier accounted for Russia's Igor Andreev 6-4, 6-2.
Roddick had too much class for the 25-year-old Australian, who fought hard but couldn't handle the power and consistency of the former world number one.
Matosevic but made too many errors to trouble Roddick, who was always able to rely on his booming serve for easy points whenever he was in trouble.
"It was alright, I thought the second set was probably better than the first," Roddick said later.
"The first match is always a little anxious, but I was able to work my way into the match, and it wasn't a bad start.
"I was able to put him into some long points and make him produce something," he added.
"He was able to do it early but it wore on him as the match went on and I think he got a little bit more impatient and that was to my benefit."
Roddick faces a couple of potentially dangerous matches if he is to reach the final and defend his title, with Cypriot Marcos Baghdatis seeded to meet him in the quarter-finals and Spaniard Fernando Verdasco in the semis.
