Joey Wiemer’s time with the San Francisco Giants ended before it ever really began.
Less than a month after acquiring the 26-year-old outfielder from the Miami Marlins in a cash deal, the Giants designated Wiemer for assignment on Wednesday night to make room on the 40-man roster for newly signed reliever Jason Foley.
It’s a quick turnaround for Wiemer, who never got the chance to suit up in orange and black. Now, he’ll head to waivers-where another team could scoop him up-or he could remain in the Giants’ system if he clears.
Wiemer’s name might not be lighting up headlines at the moment, but there’s still plenty to like about his game. A 6-foot-4 center fielder out of Sylvania, Ohio, Wiemer was a fourth-round pick by the Milwaukee Brewers in the 2020 MLB Draft after a standout college career at the University of Cincinnati. He made a splash as a rookie in 2023, launching 13 home runs and flashing the kind of raw tools that had scouts buzzing.
But since that promising debut, Wiemer’s path has been a bit rockier. In limited big-league action over the past two seasons, he’s struggled to find consistency at the plate.
He hit just .154 in 19 games for the Brewers in 2024, and his brief stint with the Reds that same year consisted of a single plate appearance-though he did work a walk. In 2025, he saw more time with the Marlins, hitting .236 with a .715 OPS over 27 games.
While the offensive numbers haven’t jumped off the page recently, Wiemer still brings value with his speed, defensive range, and sneaky power. He’s the kind of player who can cover a lot of ground in center field and make pitchers think twice when he’s on base. There’s enough upside here for another team to take a flyer on him, especially with a full offseason ahead.
For the Giants, this move was about roster math. With Foley joining the bullpen mix, someone had to go, and Wiemer ended up being the odd man out.
It’s a calculated risk-one that could see another club capitalize on Wiemer’s potential. But for San Francisco, the priority was adding a reliable arm to the pitching staff heading into 2026.
So, Wiemer heads back into limbo, waiting to see where the next chapter of his baseball journey takes him. He’s shown flashes of being a big-league contributor. Now it’s just a matter of finding the right fit.
