Hayden Birdsong

23-Year-Old PitcherSP
2024 Fantasy Outlook
Known for his premium stuff and wild control heading into 2023, Birdsong kept the starting pitching dream alive by throwing more strikes than expected as a 21-year-old at Single-A and High-A. From April 26 through July 30, Birdsong had a 2.48 ERA, 1.06 WHIP, 100 strikeouts and 25 walks in 69 innings. That dominant run was book-ended by some struggles, particularly a 12.5 percent walk rate in 23 innings after a late-season promotion to Double-A. Birdsong's stuff and potential home park are still an alluring combination in dynasty leagues. The 6-foot-4 righty boasts a plus mid-90s fastball, a potentially plus low-80s curveball and a solid slider. If he shows improved control in a return to Double-A, Birdsong will have an up arrow next to his name as a potential high-strikeout mid-rotation starter who could reach the majors in late 2024 or early 2025. An eventual move to relief remains a possibility. Read Past Outlooks

Birdsong (5-6) allowed three runs on four hits and three walks over 4.1 innings Sunday, striking out 11 and taking a loss against St. Louis.
ANALYSIS
Through four innings, Birdsong had given up one run on a solo shot by Brendan Donovan. The Cardinals then tacked on two more in the fifth inning. Despite recording only 13 outs, Birdsong punched out 11 and racked up 19 whiffs. He generated 12 of those whiffs via the slider. Birdsong ends his rookie season with a 4.75 ERA and 88:43 K:BB through 72 innings. He completed six innings in just one of his 16 MLB starts.
