Merrifield’s walk-off homer lifts Royals past O’s

Rookie right-hander Heath Fillmyer maneuvered through traffic from the onset of the Royals’ 5-4 win over the Orioles on Saturday, posting only one 1-2-3 inning and that came in his final frame. Yet Fillmyer kept his team in it — throwing seven innings, scattering nine hits and giving up just two runs — and the Royals walked off on Whit Merrifield’s first career walk-off home run.
