CINCINNATI — Elias Diaz hit a tiebreaking homer, and Colin Moran also homered and drove in three runs as the Pittsburgh Pirates pulled away to their seventh straight win over the Cincinnati Reds, 8-4 on Friday night.

The Pirates are 13-4 against their Ohio River rivals this season with their longest winning streak against Cincinnati since 1991, when they took nine in a row.

The Reds are ending another disappointing season in a rut, dropping six straight and 11 of 14. Their loss on Friday was their 94th of the season, matching their total for each of the last two years. They’ve dropped at least 90 games in four straight seasons, one shy of the club record from 1930-34.

Jung Ho Kang had a pinch-hit single in the seventh, his first major-league appearance in two years.
