Kim Clijsters' final tournament will last at least one more match, after she and mixed doubles partner Bob Bryan won in the first round of the U.S. Open on Friday.
Clijsters and Bryan beat young Americans Irina Falconi and Steve Johnson 6-2, 6-2. Afterward, Clijsters took part in the Bryan brothers' signature chest bump then grinned widely.
They could have faced Mike Bryan in the second round, but he and Lisa Raymond, seeded second, were upset.
Clijsters, a four-time Grand Slam champ, is retiring after the Open and lost in the second round in singles.
The Bryans, 11-time major winners in men's doubles, won their second-round match 6-3, 6-2 over Eric Butorac and Paul Hanley.
The Williams sisters also won their second-round match. Serena and Venus defeated Klaudia Jans-Ignacik and Kristina Mladenovic 6-4, 6-0.
