Starter Ervin Santana had seven strikeouts in four innings and now has a total of 13 in his nine innings so far with just one walk.
"Again on the attack, good fastball, got it up to 94 [mph], real good slider," Yost said. "Got a changeup up to the second baseman and he ended up putting a nice swing on it [for a home run]."
Santana threw 53 pitches, a bit shy of the 60 to 65 the Royals wanted, so he went to the bullpen for more tosses before calling it a day.
Dan Wheeler, a non-roster right-hander, got three strikeouts in his one inning. He hasn't been charged with a run in six innings so far. Nate Adcock had two strikeouts in the sixth but gave up one run as he issued a walk, gave up a single, balked and hit a batter.
Everett Teaford worked a perfect inning in his first action of the spring. Donnie Joseph and Aaron Crow each had a scoreless inning.
