Giants To Promote Hayden Birdsong

The Giants will call up pitching prospect Hayden Birdsong to start tomorrow against the Cubs. Manager Bob Melvin announced the news this evening (X link via Shayna Rubin of the San Francisco Chronicle).

It’s the first major league call for the 6’4″ right-hander. Birdsong was a sixth-round pick out of Eastern Illinois in 2022. He has quickly outperformed that modest draft stock. Birdsong pitched quite well in the low minors during his first full professional season. While he ran into a bit of trouble during his first crack at Double-A, he established himself as one of the more intriguing arms in the organization.

Baseball America ranked Birdsong the #5 prospect in the San Francisco system entering the season. The Athletic’s Keith Law slotted him 10th in February, while Eric Longenhagen and Travis Ice of FanGraphs ranked him 17th on their organizational write-up in April. All three outlets credit him with a velocity jump into the mid-90s during his first season in pro ball. Evaluators praise Birdsong’s 12-6 curveball and slider as well, though scouting reports haven’t been especially keen on his changeup.

FanGraphs writes that Birdsong is likely to end up in relief because of subpar command. The reports at BA and The Athletic were more optimistic on his chances of sticking in the rotation, though both outlets noted that he’ll need to continue improving to profile as a starter. Baseball America writes that the development of Birdsong’s command could be the x-factor, while Law suggests the biggest question is whether he’ll find a pitch with enough lateral movement to complement his north-south breaking stuff.

Even if Birdsong does wind up as a bullpen piece, that’d be a very good outcome for a sixth-round draftee who signed for less than $200K. The Giants will give him an opportunity to stick as a starter before considering that possibility. Birdsong has turned in excellent numbers for Double-A Richmond this year. In 11 starts, he worked to a 2.05 earned run average while punching out 30.7% of opposing hitters. While he issued walks at a lofty 10.1% clip, his stuff was clearly too advanced for Double-A.

The Giants bumped the 22-year-old to Triple-A Sacramento 10 days ago. Birdsong allowed five runs on eight hits and six walks over his first nine innings in the Pacific Coast League. Despite his limited experience at the top minor league level, he’ll get a look against MLB hitters. The Giants lost Keaton Winn to the injured list over the weekend, necessitating a fifth starter if they weren’t going to use a bullpen game.

Birdsong is not on the 40-man roster. The Giants will select his contract tomorrow and will need to make corresponding active and 40-man roster transactions. They don’t have any obvious candidates for a move to the 60-day injured list, so they’ll likely designate someone for assignment.
