Despite their recent loss, their overall performance against the Red Sox in past seasons shows a favorable trend. The Diamondbacks have outscored the Red Sox in their previous meetings, which is a positive indicator for their upcoming game.

Mitch Bratt, the probable starting pitcher for the Diamondbacks, holds a 3.74 ERA, which provides a reliable pitching option against Boston's offense. The Red Sox, having lost 7 of their last 10 games, seem to be struggling with consistency. Given Boston's 48.3% winning rate at home, Arizona has a viable chance of securing a win.
