Tim Henman and Mahesh Bhupathi made an encouraging start at the Legg Mason Classic with a comfortable first-round doubles victory in Washington.
Henman's last match was his five-set defeat by Feliciano Lopez
The duo beat Hyung-Taik Lee and Michael Russell 6-2 7-5 in Henman's first match since Wimbledon, but there was a shock defeat for Britain's Jamie Murray.
Doubles specialist Murray and partner Eric Butorac fell to a 7-6 2-6 10-6 defeat by Wesley Moody and Todd Perry.
And Britain's Alex Bogdanovic lost 6-4 6-2 to Robin Haase in the singles.
Bogdanovic, the British number three, struggled to find his rhythm as he crashed out of the tournament in less than a hour.
Henman will get his singles campaign under way on Tuesday against American wildcard John Isner, and the 32-year-old said his opening doubles win had given him a welcome confidence boost.
"It's great to start the trip off with a win," Henman told his personal website.
I'm just going to concentrate on my own game
Tim Henman on his return to singles action
"We both played pretty well and we gelled together nicely. I'm a bit more used to the speed of the courts and the way the ball reacts off them, and now Im looking forward to my singles match.
"He can obviously play well given he won the challenger event in Lexington recently, so he deserves his wild card.
"He's going to be confident and he doesn't have a lot to lose so I'm expecting him to come out onto court all guns blazing.
"I'm just going to concentrate on my own game and if I can be aggressive and serve well then I'm confident I can hurt him."
The world number 73 will meet eighth seed Benjamin Becker in round two if he sees off Isner, the world number 416.
Andy Murray had been scheduled to return from a wrist injury in Washington but has delayed his comeback until next week's Montreal Masters.
Henman's last match was the dramatic five-set defeat by Feliciano Lopez at Wimbledon.
