Juncheng Shang vs Marco Trungelliti — R128 — US Open

The opening set gave Marco Trungelliti zero winners and 38 percent of first-serve points won, the kind of start that settles most first rounds. Then Shang served for the second set. Trungelliti broke in game 12 for 6-6, took the tiebreak, and the 36-year-old Argentine dirtballer, built to lengthen rallies rather than end them, turned the rest into attrition — saving 12 of 19 break points and winning 88 percent of his first-serve points in the decider after breaking in game 1 for 1-0. Shang out-hit him 45 winners to 38 and won 141 of the 271 total points; it bought him one saved match point. Four hours and 20 minutes later, in a first meeting on record, Trungelliti has the second round at the US Open.
