SAN FRANCISCO — Before the regular season concludes on Sunday, manager Tony Vitello has one last piece of business to address.

The Giants have already used 70 different players this season, surpassing the previous franchise record (66) set under former president of baseball operations Farhan Zaidi. With three games remaining, a weekend homestand against the Dodgers that begins Friday night, Vitello has one more player who needs to see the field before it’s all said and done.

Zach Morgan, who grew up in Stockton as a Giants fan, spent eight games on San Francisco’s roster this season but has yet to debut. The 26-year-old catcher rejoined the team on the taxi squad on Wednesday after Osleivis Basabe’s hamstring flared up the previous day. Vitello said he is going to find a way to get him into a game.

“Come hell or high water, I’d like to get him on that field and give him an opportunity to do something,” Vitello said.

If and when Morgan makes his major-league debut, the Giants will tie the 2025 Atlanta Braves for the most players used in a single season. When Vitello was asked about using so many players before Wednesday’s 4-2 loss to the Minnesota Twins, the first-year manager at least had a sense of humor.

“I guess being first year in the organization, you’d like to get to meet everybody,” Vitello said. “So, this is one way to do it.”

Given the amount of established regulars on the Opening Day roster, the Giants could never have envisioned needing so many players to get through one of the worst and weirdest seasons in franchise history. It’s a dizzying roster churn that’s largely been the product of an absolutely ruthless injury bug.

Since last Friday, San Francisco has placed four players — Logan Webb, Bryce Eldridge, Jung Hoo Lee and Blade Tidwell — on the injured list. Eldridge landed in concussion protocol after bumping his head at the team’s hotel in Los Angeles last week, while Lee sustained a groin contusion after fouling a ball off a sensitive area.

As for Tidwell, he’s likely headed for surgery after being diagnosed with a “high-grade” UCL sprain and could miss the entire 2027 season. Tidwell will become the Giants’ fourth young starter to undergo a UCL procedure this year, joining Hayden Birdsong, Trevor McDonald and Carson Whisenhunt.

Since August, Casey Schmitt (torn meniscus), Matt Chapman (core), Rafael Devers (core) and Daniel Susac (patella fracture) have undergone season-ending surgery. Willy Adames didn’t go under the knife, but the left elbow sprain he sustained in late August ended up ending his season.

There’s also Harrison Bader, who played just 30 games after sustaining multiple injuries, then crashing into a fire truck while riding a scooter in the wee hours of the morning.

The Giants currently have 16 players on the 60-day injured list, and according to FanGraphs’ Jon Becker, the last team with that many players on their 60-day IL was the 2021 Texas Rangers. San Francisco’s brass will have many cuts to make in the offseason, especially with prospects such as Henry Lalane and Marty Gair eligible for the Rule 5 Draft (which may not happen due to the impending lockout).

Among those on the Opening Day roster, only infielder Christian Koss and right-hander Landen Roupp remain, the latter of whom was shut down for the rest of the season.

“Odd is a good word,” Koss said. “I would have to look up how many times it’s happened in a baseball season. I imagine it’s pretty low. It’s kind of one of those things we’ve had to deal with this season.”

Injuries aren’t the only reason why the Giants have called on so many different names.

Seven members of the Opening Day roster – Patrick Bailey, Heliot Ramos, Luis Arraez, Robbie Ray, Erik Miller, Tyler Mahle, Caleb Kilian — were shipped to other teams this season. Bailey was shockingly traded to the Cleveland Guardians in May, but the rest of the bunch was dealt right before the Aug. 3 trade deadline.

The abnormal roster churn has led to its share of odd facts and figures.

San Francisco has also had a franchise-record 17 players make their MLB debuts, the latest being outfielder Bo Davidson. Vitello has also used 15 different leadoff hitters, tied for the most used by a single team in MLB history (since at least 1898).

The Giants have had six different players homer while playing catcher this season which, per Sarah Langs, is tied with the 2022 Reds and 2019 A’s for the most in a single season. Five players — César Perdomo (No. 83), Seth Lonsway (No. 86), Braxton Roxby (No. 90), Scott Bandura (No. 91) and Davidson (No. 94) — have worn numbers that have never previously been used in franchise history.

For Vitello, if there is any semblance of a silver lining, it’s that he’s experienced “so many cool moments and be a part of kids’ lives.” On Wednesday, Vitello recalled seeing video of Davidson’s family celebrate his first career hit, a single to cap off a nine-pitch at-bat.

“That’s been a huge bright spot on a year where there’s been a lot of days — full transparency — back in the locker room that aren’t too pretty,” Vitello said.
