Hayden Birdsong: Everything you need to know

Birdsong underwent successful UCL reconstruction surgery on his right elbow Wednesday, Susan Slusser of the San Francisco Chronicle reports. Birdsong was diagnosed with a sprained UCL in mid-March and elected to go under the knife. The right-hander will miss the entirety of the 2026 campaign and likely at least the first couple months of 2027.

The Giants moved Birdsong (forearm) to the 60-day injured list Saturday, Justice delos Santos of The San Jose Mercury News reports. Birdsong is scheduled to undergo Tommy John surgery next week, so his move to the 60-day IL was inevitable. The transaction frees up a spot on San Francisco's 40-man roster for veteran reliever Ryan Borucki, who was signed to a one-year contract Saturday.

Birdsong (forearm/elbow) is scheduled to undergo Tommy John surgery next week, Alex Pavlovic of NBC Sports Bay Area reports. An MRI on Birdsong's right arm Sunday revealed a Grade 2 forearm strain and a UCL sprain. After receiving a second opinion, the 24-year-old righty has opted to undergo surgery to address the issue, which will rule him out for the entire 2026 campaign as well as the first few months of the 2027 season.
