Yost on Duffy: 'He had a lot of things working for him tonight'

Ned Yost on Whit Merrifield and Ryan O'Hearn's grand slams: "It's always fun to see kids add to their story. O'Hearn's worked so hard and has struggled in this park, but grand slam in his home state is kind of cool, and Whit's story — what he's been able to accomplish since he's been here has just been amazing."
