The San Francisco Giants’ 2026 season has turned into a grind on the mound, and the injury list is the kind of thing that can sink a staff before it ever finds its footing. With the club sitting at 59-85, the pitching problems have been a major reason why a team that once ruled the NL West is now stuck far from the top of the division and only ahead of the last-place Colorado Rockies.
The biggest issue hasn’t just been inconsistency. It’s been attrition.
The Giants entered the year needing meaningful seasons from veteran starters, but Logan Webb and the recently traded Robbie Ray never fully became the ace-level anchors the club needed. The bullpen has also let plenty of leads slip away.
Still, the most damaging blow has come from the sheer number of arms that have gone down.
Five Giants pitchers have already been lost for the 2026 season. Four of them have had Tommy John surgery to repair ligament damage, either before the season or during it. Another, prized pitching prospect Carson Whisenhunt, has a torn ulnar collateral ligament and is expected to undergo Tommy John surgery as well, which would make it five out of five.
That kind of total is jarring, even in an era when Tommy John surgery has become a familiar part of baseball life. The source notes that the Giants are among the teams with the most Tommy John surgeries since 2016, with 18, behind the Reds (21), Brewers (19), Yankees (17), and Mets (17). It also cites the broader picture: over the last five seasons, 29 MLB pitchers have had Tommy John surgery on average, and nearly 39% of all current MLB pitchers have undergone the procedure at least once in their careers, according to the National Library of Medicine.
The Giants, though, are still looking for answers. President of Baseball Operations Buster Posey said the team has examined ways to address the issue, but he does not believe the problem starts with the club’s medical staff or the way injuries are handled.
“I’m not going to pretend to share medical advice because I don’t know it," Posey said, per a Sept. 4 report in the San Francisco Chronicle. "I think some of this, I hope some of this, is just a little bit of ‘it all happens at once.’ We’ll have to look and see if there’s anything we need to adjust, but I have the utmost trust in our medical group.”
Whisenhunt, for his part, sees the situation as part of the hard reality of pitching in this era. In his view, the strain is built into the job.
“It’s along the lines of, ‘If you play long enough, something’s bound to happen,’” Whisenhunt said. “It’s a select few that get away with having nothing go wrong throughout their career.
This could have happened to me any time on any pitch. It just happened to be now."
“If I was to break it down, and how many pitches I’ve actually thrown in my lifetime... I couldn’t tell you how many bullets have gone from my hand.
Every time you do that, you’re straining something. Throwing motions are not normal; it’s not natural.
That’s why (underhand) softball pitchers can throw every day.”

Giants Have Two Prospects Surging At Exactly The Right Time
The Giants are getting timely traction from two prospects whose progress matters for the depth chart as much as it does for the farm system buzz. Keyner Martinez, a right-handed pitcher with the San Jose Giants, has been trending up with a strong recent stretch that includes a 0.57 ERA over his last three starts, a nice sign for a young arm trying to turn flashes into something more dependable.
Diego Velasquez has also answered an important test after moving up to Triple-A Sacramento. He has handled the jump well, batting .300 with a .400 on-base percentage in 107 plate appearances, and his steady production only strengthens his case as one of the more intriguing names in the organization. For a team always looking to line up the next wave, both players are surging at the right moment. [Read more 🡒]
Tony Vitello Opens Up About How The Giants Lost Belief Early
Tony Vitellos first season running the Giants has already given him a crash course in how quickly a major league clubhouse can tilt when the results turn south. In a recent interview, the rookie manager said the clubs rough opening to the 2026 season did more than add losses to the record, it chipped away at the credibility and confidence a team needs to carry itself through the long grind of the year.
Vitello also spoke candidly about the jump from college coaching to managing in the pros, a transition that has asked him to adjust in real time while the Giants have tried to steady themselves. Even with the frustration of the seasons early stretch still hanging over things, he sounded determined to treat the experience as part of the learning curve, hoping it leaves him better prepared for whatever comes next.

Giants May Be Reliving An Expensive Matt Chapman Problem
Matt Chapmans first season in orange and black has turned into the kind of reminder the Giants would rather avoid. The third baseman has battled injuries and performance issues in 2026, and the year ended with core surgery and a shutdown that leaves the club staring at the rest of a long contract he is still owed. For a team that has spent years trying to stabilize the infield, the concern is no longer just about one lost season. It is about how much of Chapmans remaining value can still be salvaged.
The uncomfortable part is how familiar this all looks in San Francisco. The Giants have been down this road before with Evan Longoria, whose own later years in orange and black were shaped by injuries and diminishing production as the wear of age caught up with him. Chapman is not Longoria, and the comparison is not perfect, but the pattern is hard to miss for a club that once hoped it was buying reliability. Now the question hanging over the Giants is whether this is a temporary setback or the start of another expensive decline they have to manage. [Read more 🡒]
