Royals pitcher Zack Greinke missed his last scheduled start on Sunday due to a shoulder ailment.
The previous week, Greinke had tweaked the shoulder during a game. Trainers came out to look at him but determined he was fine and he didn't even leave the game.
The next day he reported no pain in his shoulder so everyone thought he was good to go.
Then the Royals announced that he wouldn't make his scheduled start last Sunday throwing a curveball to Kansas City fans.
So what's going on?
There's no official word on what the injury was from the Royals perspective but manager Ned Yost did say Greinke threw on Wednesday and felt fine.
"He turned it loose (Wednesday) and felt good, no problems," Yost said before his players went through a brief on-field workout Thursday at Kauffman Stadium.
And after the workout, Yost said he still expects Greinke to pitch on Friday.
Greinke's turning into the 2009 version of himself going 4-0 with a 3.00 ERA in his last five starts.
