CINCINNATI (AP) Marlon Byrd had three hits, and Pedro Alvarez hit a two-run homer high off the batter's eye on Friday night, leading the Pittsburgh Pirates to a 4-1 victory over the Cincinnati Reds in a series that will decide which could host the NL wild-card game.

Both teams clinched postseason berths this week. Whoever wins the three-game series would be assured of hosting the one-game playoff on Tuesday night.

The Pirates still had a long-shot chance of overtaking St. Louis for the NL Central title. They need to sweep in Cincinnati while the Cardinals lose three at home to the Cubs over the weekend.
