The Miami Marlins (58-63) head to Fenway Park on Saturday afternoon looking to snap a rough stretch that saw them drop five of their last six games, while the Boston Red Sox (66-56) aim to bounce back from consecutive series losses that have stalled their playoff push.
Cal Quantrill takes the mound for Miami against Boston's Brayan Bello in what promises to be a pitcher-friendly affair, with the total sitting at 9.5 runs and both starters showing recent signs of effectiveness despite modest season numbers.
With Boston holding a commanding 7-3 edge in the last 10 meetings between these clubs, the Red Sox will look to leverage their strong 39-22 home record to get back on track, while the Marlins seek to continue their surprising second-half surge that has them 14-12 since the break.

Boston Red Sox vs. Miami Marlins preview
The Marlins head into Fenway Park carrying some momentum on offense, averaging 5.1 runs per game in August despite their recent struggles against Cleveland.
Boston finds itself in a precarious spot after dropping six of seven games, a stark contrast to their blistering 17-7 July record that had them looking like legitimate playoff contenders.
On the mound, Cal Quantrill has been quietly effective lately for Miami, allowing just one run across his last five starts, while Brayan Bello stumbled in his previous outing against San Diego but had been stellar through July.
The Red Sox remain formidable at Fenway with a 39-22 home record, but their road woes (seven games under .500 away from Boston) highlight just how crucial this homestand could be.
Both bullpens have been taxed recently, with Boston's relief corps sitting at just a 59.3% save rate and Miami's pen blowing 19 of 48 save opportunities this season.
With neither team carrying much momentum into this interleague clash, the pitching matchup between two righties who've shown flashes of dominance could determine whether runs come at a premium or flow freely at the friendly confines of Fenway.
