Ned Yost felt Jakob Junis was laboring to begin the fifth inning on Monday night, so he told bench coach Dale Sveum that he'd pull the right-hander if his struggles continued.

At the time Junis was throwing a no-hitter.

"Dale thought I was kidding," Yost said, "but I honestly had no idea."

Junis had hit three batters and walked two more, but he did not allow a hit until one out in the seventh inning.

The Kansas City Royals were in the midst of a 10-0 win over the Seattle Mariners.

"I was paying attention to the score, but I wasn't paying attention to how many hits they had," Yost said. "I looked up and saw he had a no-hitter and I was completely oblivious to it."

Junis got through the seventh inning, running his scoreless streak to 14 innings to start the season.
