Buster Posey isn’t worried about overusing the Giants’ younger starting pitchers.

Posey joined KNBR 680’s “Murph and Markus” on Thursday and detailed why he isn’t paying any mind to hypothetical inning caps for younger arms such as Landen Roupp and Hayden Birdsong entering the second half of the 2025 MLB season.

“We want to take care of them, but at the same time, at some point they’re going to have to pitch whatever the threshold was — and that’s the hope. I know that’s their goal as well,” Posey told Brian Murphy and Markus Boucher. “So, these guys are in tremendous shape; they take care of their bodies. And it’s not something that I tend to overthink at all.

“We’ve been really clear that we want our starting pitchers to go as deep into games as they possibly can. And I think it’s a disservice to the player to say, ‘OK, this is how many innings you’re going to throw this year, this is your marker.’ Even if you ballpark it, I think it’s just a mental disadvantage to that.”

It doesn’t appear the Giants have set any limits on what their younger arms can do. After all, they’re a core part of San Francisco’s season, supporting 2025 MLB All-Stars Logan Webb and Robbie Ray, who have pitched a combined 244 2/3 frames over 20 starts each.

Roupp and Birdsong, at least, have done their parts. The 26-year-old Roupp is third on the team in innings pitched with 96 1/3 and has sustained a 3.27 ERA and 1.45 WHIP. And Birdsong, 23, is fifth in innings with 65.2 and holds a 4.11 ERA with a 1.45 WHIP.

San Francisco is in the thick of the NL playoff race with its 52-45 record. The Giants enter the second half of the season six games back of first place in the NL West behind the defending champion Los Angeles Dodgers and 0.5 games behind the San Diego Padres for the third and final Wild Card spot.

The Giants surely will rely on Webb and Ray to carry the franchise to the finish line, but Posey and San Francisco also will look to the young arms for continued support — especially as key free-agent signing Justin Verlander, 42, remains winless through his first 15 starts for San Francisco.

“Yes, you want to take care of the guys, but also, we want our guys to take the ball as much and as often as they can,” Posey reiterated to Murphy and Boucher.
