The San Francisco Giants placed right-handed pitcher Tristan Beck on unconditional release waivers on Monday, ending his tenure with the organization after four major-league seasons.
The move came amid a broader postseason roster cleanup following a 65-97 campaign that left the club 35 games out of first place in the National League West and eliminated from contention well before the final week.
For a 30-year-old who once appeared poised for a larger role, the release marked the quiet conclusion of a career defined as much by injuries and organizational shuttling as by his early promise.
Beck, a Corona, California native and Stanford product, entered professional baseball with significant pedigree.
The Atlanta Braves selected him in the fourth round of the 2018 draft, and he signed for a $900,000 bonus after posting an 8-4 record and 2.98 ERA as a junior.
Less than a year later, the Giants acquired him and Dan Winkler from Atlanta in the July 2019 trade that sent closer Mark Melancon to the Braves.
After progressing through the minors, Beck made his major-league debut on April 20, 2023.
That season proved his most substantial, as he appeared in 33 games (including three starts), logged 85 innings, and posted a 3-3 record with a 3.92 ERA and 68 strikeouts.
His trajectory was interrupted in spring training 2024 by a rare upper-arm aneurysm that required vascular surgery at Stanford.
The procedure, similar to the one that briefly sidelined David Cone decades earlier, kept him off the mound for most of the year; he managed only seven appearances and 16 innings upon his return, though he posted a sparkling 1.69 ERA in limited duty.
He rebounded for a fuller workload in 2025 (31 appearances, 56 2/3 innings, 4.61 ERA) before a frustrating 2026 campaign in which he bounced repeatedly between San Francisco and Triple-A Sacramento.
Across 14 big-league outings he threw just 19 innings, allowing 21 hits and 11 earned runs for a 5.21 ERA and 1.37 WHIP while striking out only nine batters.
He did collect his only win of the season and recorded one save, finishing with five scoreless innings in his final three appearances.
Over 85 career games with the Giants, Beck compiled a 5-3 record, 4.08 ERA, and 132 strikeouts in 176 2/3 innings.
The unconditional release places him on the open market as a free agent, free of any remaining contractual ties to the club.
In an organization that used a record number of players and cycled through an overworked bullpen throughout 2026, Beck’s departure is one of several quiet exits that reflect the Giants’ need to clear space and reassess depth options heading into an uncertain offseason.
