The Chicago Cubs welcome the struggling Pittsburgh Pirates to Wrigley Field on Friday night, with Chicago looking to extend their impressive season as heavy -196 favourites against a Pirates squad that sits 20 games below .500.
With Braxton Ashcraft taking the mound for Pittsburgh against Colin Rea, the matchup presents an intriguing clash between the Cubs' third-ranked offence that averages over five runs per game and a Pirates team desperately seeking momentum in the season's final stretch.

Chicago Cubs vs. Pittsburgh Pirates preview
The Cubs return to Wrigley Field on Friday looking to extend their impressive home record against a Pirates team that's struggled mightily this season, sitting 17 games under .500 at 51-71.
Chicago's offense has been one of baseball's most productive units, averaging over five runs per game and ranking third in the league, while Pittsburgh's anemic attack sits dead last with just 3.5 runs per contest.
The pitching matchup features rookie Braxton Ashcraft making his mark for Pittsburgh with a solid 3.23 ERA in limited action, facing veteran Colin Rea who brings experience but has been inconsistent with a 4.48 career ERA.
Pittsburgh's bullpen has been a major weakness all season, converting just 56.8% of save opportunities with 19 blown saves, which could prove costly in a tight game at the friendly confines.
The Cubs enter this series riding their offensive firepower and superior pitching depth, having allowed nearly a full run fewer per game than the visiting Pirates.
With Chicago sitting 17 games ahead in the standings and fighting for playoff positioning, they'll look to take advantage of a Pirates squad that's clearly in sell mode as the season winds down.
