When Holland's velocity dropped earlier this season, he almost always was able to get it back to 96 mph. That doesn't appear to be the case anymore.
"There's a little bit of concern," Royals manager Ned Yost said. "You have to look at a closer's mentality and he's got that. He's got the heart of a lion."
No one will dispute that. Holland gutted it out with an almost unhittable slider that peaked at 86 mph, actually above his usual velocity for that pitch.
"His slider is really good," Yost said, adding that Holland likely can survive just on that pitch.
Yost has said repeatedly lately that Holland has no structural damage in his right shoulder or arm, though Holland has been sat down because of soreness several times.
"I think it's from the pounding physically over the years," Yost said. "We're at the end of the season now ... even last year his velocity dropped down at the end but then look at what he did in the postseason."
Yost isn't about to move Holland out of the closer's role mainly for the obvious reason -- Holland is succeeding at it. Tuesday, Holland got his 31st save in 35 opportunities.
"It's a day-to-day thing," Yost said. "We'll keep evaluating. But every time we put Holly out there, he gets the job done."
Holland was unavailable after the game.
