Shane Bieber had struck out at least eight in 20 straight games before he fanned just seven against the Seattle Mariners on Sunday.

Bieber was pulled after issuing his fourth walk and finished his shortest outing of the season at 4 2/3 innings.

"You have to ride the highs with the lows. And today, I'm frustrated that I wasn't able to go out there and do what I know I'm capable of doing," he said. "Objectively, the bullpen did a phenomenal job saving me there, and we almost scratched one out."

Bieber leads the majors with 92 strikeouts after starting the season with 10 or more in his first four outings, another Major League record.
