NEW YORK (AP) — Matt Gorski and Jared Triolo each connected for a two-run homer off New York Mets starter Clay Holmes and the Pittsburgh Pirates finally mustered some offense in a 4-0 victory at rainy Citi Field. Five pitchers combined on a six-hitter as the last-place Pirates won for the fourth time in 17 games to prevent a series sweep. They’re 3-3 under Don Kelly, promoted from bench coach to manager when Derek Shelton was fired last week. Rookie reliever Chase Shugart tossed 2 1/3 innings for his second career win. It was the fourth shutout this year for Pittsburgh, which has gone a franchise-record 20 games in a row without scoring more than four runs.
