Boston Red Sox vs. Kansas City Royals preview

The Red Sox ride into this series finale with serious momentum, having won six straight and outscored opponents 34-15 during that stretch while solidifying their grip on the top wild card spot.

Kansas City finds itself in a familiar spot this season - tantalizingly close to relevance but struggling to string together the consistent offense needed to make a real playoff push, sitting four games back of that final wild card berth.

Michael Wacha takes the ball for the Royals coming off his best stretch of the season, posting a 1.40 ERA over his last three starts including a dominant eight-inning gem against Toronto.

Boston counters with newly acquired Dustin May making his Red Sox debut after coming over from the Dodgers at the deadline, though his 4.85 ERA and recent struggles suggest the transition hasn't been seamless.

The pitching matchup tells an interesting story - Wacha has historically thrived at Fenway Park with a 2.88 ERA in 12 career starts there, while May surrendered four runs to these same Red Sox in his last outing just over a week ago.

With Boston's offense averaging over six runs per game during this hot streak and the Royals needing every win they can get to stay in the hunt, Wednesday's finale sets up as a classic getaway day battle between desperation and momentum.
