The Pittsburgh Pirates are a win away from their second 90-win season in three years after going 20 in a row without reaching that mark. The Pirates enter the second-to-last week of the season four games back, and while they don't play the NL Central leaders for another week, a four-game series in Colorado beginning Monday night could help them trim the gap before then. After Sunday's 4-3 road win, Pittsburgh (89-56) took two of three against the Los Angeles Dodgers over the weekend to gain a game on St. Louis in the division and remain two ahead of the Chicago Cubs for the top wild card.
