The Yankees sweep their cross-town rivals in the first double-ballpark doubleheader since 1903 with identical scores, 4 – 2 in an afternoon tilt at Shea Stadium and 4 – 2 in an evening contest at Yankee Stadium. It proves to be quite an interesting day in New York as Mike Piazza is hospitalized with a concussion after being beaned by Roger Clemens, Dwight Gooden gets his first Shea win since 1994 and a bizarre obstruction call on Mets first baseman Todd Zeile causes the first game to be played under protest.
