NEW YORK — The first and last pitch of the All-Star game could well be “New York, New York.”Young ace Matt Harvey of the Mets will start for the National League on his home mound. Mariano Rivera, in his final season, may well finish for the AL.“Having the opportunity to take the ball is something I’ll never forget,” Harvey said Monday.On July 16 last year, Harvey was pitching for Triple-A Buffalo against Toledo before 5,885 fans at Coca-Cola Field. On Tuesday night, he’ll be starting against Detroit’s Max Scherzer in front of a sellout crowd at Citi Field and a worldwide television audience.At 24, Harvey is the youngest All-Star starting pitcher since the Mets’ Dwight Gooden in 1988, when he was 23.
