Royals vs Diamondbacks prediction
My Royals vs Diamondbacks best bet: Under 8.5 (-119 at DraftKings)
The Kansas City Royals and Arizona Diamondbacks are both scuffling as of late.
Kansas City is 3-9 in its last 12 games, with the Royals' offense being held to three runs or fewer in nine of those contests.
On the other side of the diamond, Arizona sports just two wins in its last eight games.
We’ve got a strong pitching matchup on tap, with Kansas City lefty Kris Bubic boasting a 2.25 ERA on the season.
Meanwhile, don't let Eduardo Rodriguez's 5.13 ERA fool you, as Arizona's southpaw has allowed just six runs across his last 27 1/3 innings.
The Royals also have a strong bullpen (3.55 ERA), and while the D-backs' pen has been weaker, we can trust them given how Kansas City's offense has been faring.
