SAN FRANCISCO — The Giants’ rotation took a hit when the team optioned Hayden Birdsong to Triple-A Sacramento following the worst start of his career. On Friday, that unit took another blow.

The San Francisco Giants already had a glaring need for rotation help, and now that pursuit comes with flashing red emergency lights.

Birdsong’s demotion now leaves the rotation as Logan Webb, Robbie Ray, Justin Verlander, Landen Roupp and others. Webb and Ray were both All-Stars, but they’re both coming off nightmare starts, and they’ve struggled more recently than they previously had all season.

Hayden Birdsong’s demotion combined with Justin Verlander’s inconsistency highlight the team’s need for major-league rotation depth as the July 31 trade deadline looms. It’s an issue that has been brewing since the team sent Kyle Harrison and Jordan Hicks to the Boston Red Sox in exchange for Rafael Devers.

Young Giants starter Hayden Birdsong had a disastrous outing in San Francisco's 9-5 loss to the Atlanta Braves on Monday at Truist Park.

With Hayden Birdsong's demotion, it’s clear the Giants have had enough of the rotation’s struggles and are moving in a different direction.

Hayden Birdsong's season reached a new low Monday as he was pulled in the first inning of a 9-5 loss to the Braves after allowing four walks, a 3-run double and hitting a batter.

Rookie Drake Baldwin drove in six runs, Ronald Acuña Jr. scored three times and the Atlanta Braves beat San Francisco 9-5, handing the Giants their season-high sixth straight loss.

Hayden Birdsong may have given up three runs and taken the loss against the St. Louis Cardinals on Sunday, but the San Francisco Giants rookie racked up 11 strikeouts in 4.1 innings.
