Kansas City was competing for the American League Wild Card that year, Yost said, and he felt that having the right-hander in the bullpen would give the Royals more options at the end of the season.
"The first time I brought him in a ballgame as a reliever, he was 96, 97 miles an hour," Yost said. "Wade was throwing 91, 92 miles an hour as a starter."
Yost knew he'd made the right move on Sept. 7, 2013, in Davis' second relief outing. The Royals and Tigers were tied at 1 heading into the top of the fifth.
