Arizona Diamondbacks vs Kansas City Royals Prediction

You can make a case for the Royals with Wacha on the mound as he’s been strong with a 3.36 ERA and 1.10 WHIP. Burnes will make his season debut as he’s been dealing with elbow and shoulder issues. The Royals have the clear edge on the mound. However, as I said yesterday, the Diamondbacks are in the thick of the playoff race and need to take advantage of these spots if they’re going to see the postseason. Just get it done. Cheap price. Give me the Diamondbacks.
