San Francisco Giants DFA Recently Signed Outfielder
Brennan's 2026 season with San Francisco never found traction.
In 23 plate appearances at the big league level this year, he managed two hits, both singles, continuing a persistent trend across his career.
#SFGiants roster moves:
— SFGiants (@SFGiants) June 10, 2026
- LHP Reiver Sanmartín (#48) returned from his rehab assignment and reinstated from the 60-day Injured List.
- RHP Tristan Beck optioned to Triple-A Sacramento.
- OF Will Brennan designated for assignment.
A Career of Promising Minors, Disappointing Majors
The Giants signed Brennan to a major league split deal in February after the Guardians non-tendered him following a season-ending Tommy John surgery on his left elbow in June 2025, followed by sports hernia surgery in September.
San Francisco GM Zack Minasian said at signing that the team had liked Brennan for some time and described him as gritty and hardworking.
The bat never delivered on those intangibles.
He has now been optioned to Triple-A Sacramento four times this season alone, a cycling pattern because of both his remaining option years and the organization's persistent hope that the minor league version of Brennan would translate to the big league level.
The minor league version is useful.
The Giants reinstated Reiver Sanmartin from the 60-day IL and optioned Tristan Beck. Outfielder Will Brennan was designated for assignment.

His career Triple-A slash line is .299/.365/.436 with a 12.6 percent strikeout rate that mirrors almost exactly his major league strikeout rate of 12.7 percent.
The problem is that his major league OPS sits at .666 across 889 career plate appearances with Cleveland and San Francisco, a number that shows the batted ball luck fluctuations and low walk rate that limit what a contact-only profile can sustain.
Brennan has three-plus years of service time, which gives him the right to reject an outright assignment to the minors and elect free agency.
