Royals vs Diamondbacks Prediction

It would be nice to know who is taking the mound for the Diamondbacks, but they’re the better team and in the thick of the playoff race. Even with the Royals playing spoiler and winning games lately, this series is a must-win for the Diamondbacks. The Royals are still a bottom-feeder in the league and a team that should get contenders excited when seeing them on the schedule. Also, Cameron has a 4.95 ERA and a .274 allowed batting average at home. I’ll side with the Diamondbacks on the road.
