The Boston Red Sox return to Fenway Park this Saturday riding an eight-game road winning streak, hosting the struggling Pittsburgh Pirates in what could be a pivotal contest for Boston's playoff aspirations.
With the Red Sox sitting just 3.5 games behind first-place Toronto and firmly in wildcard contention, they face a Pirates team mired in last place but showing recent signs of life with improved starting pitching.
The matchup features Pirates right-hander Johan Oviedo, fresh off his first win in nearly two seasons, against Boston's trade deadline acquisition Dustin May, who has been markedly better at home this year with a 3.24 ERA.

Boston Red Sox vs. Pittsburgh Pirates preview
The Red Sox return to Fenway riding an impressive hot streak, having swept the Orioles in Baltimore after taking three of four from the Yankees, putting them just 3.5 games back of Toronto in the AL East hunt.
Pittsburgh arrives in Boston with modest momentum of their own, winning three of five recently despite being destined for another last-place finish in the NL Central.
The pitching matchup heavily favors Boston, with trade acquisition Dustin May bringing a solid 3.24 home ERA compared to Johan Oviedo, who's still finding his rhythm with just three starts since returning from injury.
Boston's offense has been clicking at .252 as a team with 161 homers, a stark contrast to Pittsburgh's struggling .234 average and league-worst 3.6 runs per game.
The Pirates' bullpen could be tested early if Oviedo continues his pattern of lasting just five innings or less, while the Red Sox relief corps has been more reliable despite some blown saves.
With playoff implications on the line for Boston and Pittsburgh playing out the string, expect the home crowd at Fenway to fuel another strong Red Sox performance in this Saturday matinee.
