Columbia’s Michael Zheng comes full circle as Americans advance at US Open

• Former Ivy League star wins US Open debut

• Shelton and Tiafoe advance to third round

• Pegula cruises past Kenin in 56 minutes

Michael Zheng spent years making the long trek from northern New Jersey, first by bus across the Hudson River to the Port Authority bus terminal and then nearly the full length of the No 7 subway line, all for the opportunity to train at the USTA Billie Jean King National Tennis Center. On a rainswept Wednesday afternoon in Queens, the destination was the same but the purpose had changed entirely.

The 22-year-old American wildcard and two-time NCAA champion from nearby Columbia University brushed aside Hungary's Fabian Marozsan 6-4, 6-4, 6-2 to win his rain-interrupted US Open debut, providing one of the more unlikely highlights on a busy day for the home contingent in New York.
