(CNN) -- Andy Murray began the defense of his AEGON Championships title at London's Queen's Club with a 7-6 (10-8) 6-3 victory over Ivan Navarro of Spain.
Britain's world number four needed a tie-break to edge a tight first set and made a crucial break in the first game of the second before striking again in the ninth to take the match.
"It was a good, tough first match," Murray told the tournament's official Web site.
"I haven't played a serve-and-volleyer this year, but I thought I moved pretty well and hit the ball back well once I got into the rallies."
Murray will meet either U.S. competitor Mardy Fish or Santiago Giraldo of Colombia in the third round of the traditional Wimbledon warm-up event.
Elsewhere at Queen's, four-time winner Andy Roddick thrashed Igor Kunitsyn of Russia 6-2 6-1 and Germany's Rainer Schuttler upset Gael Monfils of France 6-3 6-7 (4-7) 6-2.
