SCOTTSDALE, Ariz. -- There were no managerial challenges Wednesday on umpires' calls during the Royals' first game set up for the expanded instant replay system.
"Don [Wakamatsu, bench coach] and I saw it really well. It was kind of inconclusive so if we would have challenged that, we would have lost the challenge," manager Ned Yost said.
However, it wasn't a waste of time.
"It was a great learning experience and I think I learned a good lesson," Yost said. "You don't have to rush right out [to challenge], you can take your time as long as you get out there before the next pitch is thrown."
Yost and his bench were in communication with staffers monitoring the replays in a TV truck, the first of five rehearsals for the regular season.
Yost noted that in the past when he disagreed with a call and wanted to argue, he'd jump up, rush out and confront the umpire.
"There's not a need for that anymore," the skipper said. "You can actually bide your time, buy a little time for the guys in the video room. As long as you can get up before the next pitch is thrown ... and sometimes we might get the information before I even step out to decide if I want to go out."
