CINCINNATI — Scott Rolen tripled and scored the go-ahead run in the eighth inning as the Reds won their fifth straight game, 5-4 over the Pirates on Saturday night.
Cincinnati has won 15 of 16 to open a 5½-game lead over Pittsburgh in the NL Central.
It was tied at 4 when Rolen led off the eighth with a line drive off the right-centerfield wall, beating the relay with a headfirst slide into third base. Todd Frazier hit a chopper that pitcher Jared Hughes fielded too late to get Rolen at the plate.
Rolen earlier had a two-run single.
Pittsburgh manager Clint Hurdle was ejected in the top of the second after both benches had been warned following the second Pirates batter to be hit by a pitch in two nights.
Reds starter Mike Leake plunked Josh Harrison with two outs, no one on base and Cincinnati leading 2-1. Harrison and Leake briefly exchange words.
