SAN FRANCISCO >> Buster Posey executed his first true shakeup as the Giants’ president of baseball operations — a decision that required him to cut ties with someone he considers a “buddy.”

The Giants announced a flurry of roster moves on Wednesday morning, the headliner being to designate first baseman LaMonte Wade Jr. for assignment.

San Francisco also designated backup catcher Sam Huff for assignment and optioned infielder Christian Koss to Triple-A Sacramento. To fill their three roster spots, the team signed veteran first baseman Dominic Smith to a major-league contract and selected outfielder Daniel Johnson and catcher Andrew Knizner from Sacramento.

“It’s time to go,” Posey told reporters on Wednesday afternoon before the Giants’ game against the Padres. “I think we all believe that we’re better than what we’ve been with the bats the last two-and-a-half, three weeks. It’s time to go.”

The roster moves come as the Giants are in the midst of one of their worst offensive stretches in recent memory.

San Francisco hasn’t scored more than four runs in a game since Wilmer Flores hit three homers against the Athletics on May 16, the team’s longest such streak since 1965. The Giants have scored 32 runs over their last 16 games, posting a collective .594 OPS and 14-for-105 (.133) with runners in scoring position. The last time the team scored 32 or fewer runs over a 16-game span was 1992.

Posey expressed faith in Wade when he spoke to beat reporters Tuesday before the Giants’ 3-2, 10-inning loss to the Padres, but acknowledged that the team is “trying to exhaust all options.” One of those options ended up being moving on from Wade. Following Tuesday night’s defeat, Posey personally delivered the news to his former teammate.

“It was a difficult decision,” Posey said. “One of the trickier things for me is there’s still guys on this team that I played with. I had a different relationship with him as a player than I do now, but I still consider LaMonte a buddy. It wasn’t an easy thing to do, but you got to get some offense going. Smith’s been swinging the bat well this last month and hopefully he can provide a spark. ... For LaMonte, my hope is he lands somewhere and gets going and continues his career.”

Wade, who played alongside Posey in 2021 when the Giants won a franchise-record 107 games, was far from the only Giant struggling at the plate during this stretch. That said, the 31-year-old first baseman been unproductive the entire season.

Over 50 games, Wade posted a .167/.275/.271 slash line with one home run. By WAR, he had been the Giants’ least valuable player. Wade’s struggles go back to last season. Since the second half of last season, Wade has hit .188/.297/.308 and been 26 percent worse than a league average hitter.
