Greg Rusedski got back to winning ways while Andrew Murray claimed his first ATP Tour win on a good opening day for the home players at Queen's.
Rusedski was seldom put under pressure on Centre Court
Rusedski had a 6-3 6-4 win over Brit wildcard Josh Goodall in the Stella Artois Championships first round.
Meanwhile, on Court One, 18-year-old Murray thrashed Spain's Santiago Ventura 6-1 6-2 to reach round two.
However, Alan Mackin could not build on some encouraging moments and went down 7-5 4-6 6-3 to Igor Andreev.
Murray, who lost in the semi-finals of the boy's singles at the French Open last week, faces American Taylor Dent or Germany's Tomas Behrend next.
The Scot has had 10 wins in either futures or challenger events this year and took advantage of a wildcard at Queen's for his first win at the senior level.
"This was a very important match for me - one of the biggest of my career," Murray told BBC Sport.
"Playing in an ATP tournament at my age is obviously going to be a big deal. Once I got on top I didn't let the guy off the hook and finished the match off pretty well."
Murray confirmed he will play in the boy's singles at Wimbledon.
Rusedski, searching for his best form after a disappointing season, had too much grass-court experience for Goodall and took the match in just 53 minutes.
The world number 38 hit 21 aces in a dominant 6-3 6-4 win.
The British number two paid tribute to his 19-year-old opponent after the match.
"I thought he played very well - if he continues to play like that he's got a good future," Rusedski told BBC Sport.
"I've won a match here which is always a positive. I've got to think to myself that if I keep hitting my serve like this then I've got a chance with anybody.
"I've got to keep on being aggressive, make a few more returns and life will be good."
French Open runner-up Mariano Puerta pulled out of the tournament on Monday with a groin strain.
