Bryan Woo, the Mariners’ electric young right-hander off to the best start by a pitcher in club history, was scratched from his scheduled start Tuesday night as the team awaits results of an MRI on his arm.
Veteran left-hander Jhonathan Diaz was promoted from Triple-A Tacoma to start in Woo’s stead against the White Sox.
Woo, 24, missed the first six weeks of the season with inflammation in his right elbow. He had Tommy John reconstructive elbow surgery in the spring of 2021.
In his six starts this season, Woo is 3-0 with 24 strikeouts, two walks, 16 hits and four runs allowed in 33.2 innings.
His 1.07 ERA through the first six starts of a season is the lowest in franchise history, surpassing Randy Johnson’s 1.21 ERA to start the 1995 season.
The Mariners have won all six of Woo’s starts.
