Munich: Tommy Haas made light of his 36 years to open the defence of his Munich Open title with a 6-2, 6-4 win over Colombia`s Alejandro Falla on Thursday.
Haas, the second seed and ranked 16 in the world, took his career dominance over the South American to 5-1 with a 74-minute win in his first match since a fourth-round exit to Roger Federer at Indian Wells in March.
He had been sidelined in recent weeks with a right shoulder injury.
"I`m pretty happy with the win, obviously, having been laid off for a couple of weeks and not knowing how the injury would be," said the German veteran.
"I`m really happy with the way I played. It`s always great to play in front of a full crowd at home in Germany. He`s the kind of player you have to play great tennis against to beat him otherwise you beat yourself."
Top seed Fabio Fognini of Italy also made the quarter-finals with a 7-6 (7/4), 6-2 win over German wild card Dustin Brown.
