Prediction

The Royals have won the first two in this series and the offense is coming alive for this Kansas City team. They have scored four runs or more in seven of the last eight games, including 20 runs in the first two of this series. Both pitchers have been solid lately, with Kolek a tad better. I’ll ride the Royals momentum in this one.

Pick: Royals +111
