"I got to the park here and I couldn't even hold the bat," Moustakas said, "and I couldn't get my hand in my glove."
So the Royals scratched Moustakas from the lineup on Friday, and on Saturday placed him on the 15-day disabled list retroactive to Thursday. The Royals then recalled third baseman Cheslor Cuthbert from Triple-A Omaha. Cuthbert was in the starting lineup for Saturday's game against the Indians.
Trainer Nick Kenney and Moustakas both said the recovery time will be two to three weeks.
Moustakas first suffered the injury on the last road trip against the Angels, while applying a tag at third base.
"That was a big win," Moustakas said. "We needed it."
Did it hurt?
"I hit it on the barrel," Moustakas said. "I had all sorts of protection, too. They numbed it, put pads on it."
But Moustakas had a heart-to-heart with Kenney on Friday.
"Nick [Kenney] told me it's not going to go away if I keep playing," Moustakas said. "They gave me every opportunity to play, which I appreciate. But it was one of those things I just had to be real with myself."
Cuthbert, meanwhile, had a very interesting travel schedule to get to Cleveland.
The Storm Chasers were in Memphis and coming off a road trip. The team flew back to Omaha through Dallas. Then, he learned of his promotion and headed on a plane for Cleveland with a connecting flight in Atlanta.
All in one day.
So, was Cuthbert a little tired?
"Yeah, but I'm OK," he said, smiling. "It was worth it."
