The Kansas City Royals jumped out to a four run lead but could not hold on falling to Milwaukee 9-5 Friday night.

Jacob Nottingham hit a grand slam and Orlando Arcia added a three-run shot to key the Brewers rally.

Nottingham’s two-out blast to left off Danny Duffy capped a six-run rally in the fourth inning that put the Brewers ahead for good.

The comeback had begun when Christian Yelich led off the fourth with his 150th career homer.

Kansas City’s Salvador Perez went 4 of 5 with a homer, double, two runs and four RBIs.
