Boston Red Sox vs. Kansas City Royals preview
The Red Sox welcome Kansas City to Fenway Park on Monday riding high as one of baseball's most potent offenses, averaging nearly five runs per game—good for fourth in the majors.
Boston (59-51) sends veteran Lucas Giolito to the mound against the Royals' promising rookie Ryan Bergert, who has impressed with a sharp 2.81 ERA through his first 35 major league innings.
Kansas City (54-55) arrives with arguably MLB's best pitching staff, sporting the second-best team ERA at 3.52, though their offense has struggled, ranking 28th in runs scored.
The contrasting strengths create a fascinating matchup between Boston's sluggers and Kansas City's arms, with the hometown Red Sox installed as modest -145 favorites.
Bergert's ability to limit hard contact (just 6.1 hits per 9 innings) could be key against a Boston lineup that's collected 137 home runs this season, while Giolito brings valuable experience with over 1,100 career innings pitched.
