Giants Designate Will Brennan For Assignment

The Giants announced that left-hander Reiver Sanmartin has been reinstated from the 60-day injured list. Right-hander Tristan Beck has been optioned to Triple-A Sacramento as the corresponding active roster move. To open a 40-man spot, outfielder Will Brennan has been designated for assignment.

Brennan, 28, was a free agent this offseason after being non-tendered by the Guardians. The Giants scooped him up by signing him to a major league deal, a split contract that paid him $900K in the majors and $400K in the minors. He is still optionable and the Giants have made use of that, as he has already been optioned four times this year.

He has performed well in the minors but not the majors, which continues a trend for him. He has been sent to the plate 23 times at the big league level this year, with just two hits, both singles. Dating back to his time with Cleveland, he now has a .263/.301/.365 line in 889 major league plate appearances. That leads to an 86 wRC+, indicating he has been 14% below league average offensively.

He has taken 117 plate appearances at the Triple-A level this year and produced a .364/.393/.467 line and 126 wRC+. That’s propped up by an unsustainable .396 batting average on balls in play but is nonetheless a much more encouraging performance than what he has done in the big leagues. He now has 745 Triple-A plate appearances dating back to 2022 with a .324/.368/.464 line and 122 wRC+, though that is bolstered by a high .355 BABIP.

Brennan has some wheels and could have some appeal as a speed-and-defense depth outfielder, though the bat is more of a question mark. Even when he puts up good marks in the minors, he does so with a low walk rate and generally relies on batted-ball luck.

He now heads into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Giants can take as long as five days to see if there’s any trade interest. Since he is still optionable, perhaps he would hold some appeal to a team looking for extra outfield depth.

If he were to clear waivers, he would have the right to elect free agency but probably wouldn’t exercise that right. Players with at least three years of service have the right to reject an outright assignment in favor of the open market but have to forfeit their salary commitments unless they have at least five years of service. Brennan is just a bit over that three-year line and would have to walk away from the remaining money on his deal if he elected free agency.

Sanmartin, 30, was claimed off waivers from the Reds in November. He suffered a hip flexor strain in March that was expected to cost him about three months, a timeline that has proven to be pretty accurate. He logged 84 1/3 innings with the Reds from 2021 to 2025, allowing 5.66 earned runs per nine. His 19.2% strikeout rate and 11% walk rate in that span were subpar but he induced grounders on 53.6% of balls in play. He’ll be making his debut as a Giant as soon as he gets into a game.
