DETROIT -- The Giants locked up their homegrown ace on Friday, announcing a five-year, $90 million extension with right-hander Logan Webb that will keep the Rocklin, Calif., native in the club’s rotation through at least 2028.

The deal -- the biggest given to a player under Giants president of baseball operations Farhan Zaidi -- will kick in next year and buy out Webb’s final two years of arbitration and his first three years of free agency. The 26-year-old will earn $8 million in 2024, $12 million in 2025, $23 million in 2026, $23 million in 2027 and $24 million in 2028. He will also make annual donations to the Giants Community Fund that will total nearly $500,000 over the life of the contract.

“Logan is really the embodiment of the kind of player we want to build around,” Zaidi said. “When considering the performance, the competitiveness, his love and ties to the Bay Area, how much the organization means to him as a homegrown player. It’s really the perfect fit.”

Zaidi confirmed that the club had begun extension talks with Webb over the offseason, with Webb expressing interest in being “a Giant for life” during FanFest at Oracle Park in February.

“It was just important for me to be able to say I can wear a Giants uniform for a long time,” Webb said. “It’s important for not only myself, but my family. I know they’re very excited. There are a lot of diehard Giants fans in Rocklin, so I’m where I want to be. It’s an honor.”

A fourth-round Draft pick of the Giants in 2014, Webb broke into the Majors as a 22-year-old in 2019 and developed into one of the best young pitchers in baseball in 2021, when he posted a 3.03 ERA over 27 regular-season appearances and then delivered two brilliant starts in the epic National League Division Series between the Giants and the rival Dodgers that fall. 

Webb continued to raise the bar in 2022, going 15-9 with a 2.90 ERA over a career-high 192 1/3 innings while finishing 11th in NL Cy Young Award voting. He made his second consecutive Opening Day start for the Giants last month, though he’s off to a bit of a rocky start in 2023, going 0-3 with a 4.76 ERA in three outings against the Yankees, White Sox and Dodgers. 

“I am super frustrated with how my season has started,” said Webb, who will make his next start on Sunday against the Tigers. “I think there have been a lot of good positives that come out of some of the things that we’re trying to accomplish. I’ve got to be a lot better. I think the team knows that. I know that. I’m excited to start showing that. I think I’m really close. It does show that they do have a lot of faith in me and they know that some of the stuff that’s happened in the first couple of games is not going to happen, hopefully, very often.” 

Zaidi has historically avoided giving out long-term deals to pitchers and let two All-Star pitchers -- Kevin Gausman and Carlos Rodón -- depart via the free-agent market over the last two years, but he said he was thrilled to make this “exciting commitment” to Webb.  

“There really wasn’t any kind of concern about the magnitude of the deal,” Zaidi said. “I think we really just wanted to do something that was in line with the market and really fair to both sides.” 

Webb said he plans to use some of his Giants Community Fund donations to help raise awareness about the dangers of fentanyl, as he lost his 20-year-old cousin, Kade Webb, to a counterfeit pain pill in December 2021. 

“It’s a devastating thing,” Webb said. “I know how much it has affected my family. Part of the reason I want to get the awareness out is because I saw how devastating it was for my family. I really don’t want to see any other families have to deal with the same thing. It’s a really big problem. I think it’s important to get the awareness out, especially to our younger generation.”
