"He did a phenomenal job with Duffy -- calling the game, blocking pitches. His receiving is really good," manager Ned Yost said. "And I'm just waiting for him to get his first hit. I had a feeling he was going to get a homer for some reason all day long. I said, 'Hayes is going deep tonight.'"
Hayes is 0-for-16 in his 10 games so far, but it's defense that makes him valuable.
"The thing that we've got going for us this year is when we give Salvy a day off, I'm comfortable with the defense we have back there," Yost said. "Last year, we'd get the lead in the seventh or eighth inning, I had to put Salvy in games [for defense]. I don't have to do it this year."
