Channeling his inner Jimmy Connors, Andy Roddick pounded a forehand passing shot down the line to win a 20-stroke point and thrust both arms overhead, motioning to the U.S. Open spectators to make more noise.

Moments later, Roddick hit a volley into an open court and chugged back to the baseline, wagging his right index finger.

Yes, Roddick is having a grand ol' time at his retirement party — and he's not done yet.

Winning a second consecutive match since announcing the U.S. Open will be the last tournament of his career, 2003 champion Roddick stuck around by beating 59th-ranked Fabio Fognini of Italy 7-5, 7-6 (1), 4-6, 6-4 on Sunday.

Next comes a tougher test: A fourth-round match Tuesday against 2009 U.S. Open champion Juan Martin del Potro.
