Rest-of-Season Projections
2026 Fantasy Outlook
Birdsong began the season in the Giants' bullpen despite a strong showing in Cactus League play. He delivered a 2.31 ERA over 11 relief appearances before moving into the rotation, though the results were less stable than the ERA suggested. Over 23.1 innings, he issued 10 walks and surrendered four home runs. Those problems became more pronounced as a starter, where he posted a 6.17 ERA and 1.61 WHIP across 10 starts and 42.1 innings, accompanied by 27 walks. After being sent to Triple-A Sacramento, Birdsong continued to battle control, walking 30 in 39 innings with similarly poor run prevention. The Giants again have rotation depth questions, giving him another spring opportunity, but last season's command and control issues place him on the fringe. Even so, his age leaves room for improvement if he can regain consistency. Read Past Outlooks
Signed a one-year contract with the Giants in March of 2026.
Undergoes UCL reconstruction
Birdsong underwent successful UCL reconstruction surgery on his right elbow Wednesday, Susan Slusser of the San Francisco Chronicle reports.
Analysis
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.

Past Fantasy Outlooks
2025
2024
Birdsong began last season at Double-A Richmond but wound up making 16 starts for the Giants. He flashed plenty of swing-and-miss ability with a 27.9 percent strikeout rate and a pair of double-digit strikeout outings, but the young right-hander also had an ugly 13.7 percent walk rate and completed six innings in just one of his 16 starts. Birdsong has three legitimate secondary pitches in his curveball, changeup and slider, with each garnering a whiff rate of at least 32.7 percent and all three offerings earning excellent Stuff+ grades. However, his Location+ of 92 was among the worst in baseball for a regular starter, which no doubt was the main reason why opponents had an obscene 50 percent hard-hit rate. There's legitimate upside with Birdsong and he could open 2025 in the Giants' rotation, but he'll have to improve his command and control to be a reliable option in fantasy.
