Giants cut bait on Ryan Borucki, open spot for Jonah Cox

The San Francisco Giants released left-hander Ryan Borucki over the weekend, clearing the way for the veteran to immediately test the free-agent market. MLB’s transaction logs list Borucki’s designation for assignment on May 31 and his release on June 6, while MLB Trade Rumors published the news on June 7, which accounts for the apparent one-day difference in timing.

Borucki’s exit is the second half of a rapid roster pivot that began with a May 31 roster shuffle. The Giants designated him for assignment, a procedural step that puts a player under waivers and gives the club a short window to move him off the 40-man roster. In the same span, San Francisco selected the contract of outfielder Jonah Cox from Double-A Richmond, another sign that the Giants were prioritizing a new look in their position-player depth over keeping Borucki around as an immediate bullpen option.

Cox’s promotion was notable because it skipped the usual seasoning stop. In an recap of Cox’s debut, the Giants described needing a spark and turning to their Double-A system, where Cox was producing at a high level. Cox, 24, entered a game at Coors Field as a pinch-runner and scored, then doubled in his first major league at-bat. The Giants won 19-6 in that matchup, and Cox’s introduction carried more than just highlight value.

San Francisco’s decision to bring Cox up directly from Double-A was supported by a strong Richmond stat line. reported that Cox hit.400 for the Flying Squirrels, going 64-for-160 with 11 doubles, five triples, six home runs, 35 RBIs, 31 runs and 27 stolen bases in 44 games. The same coverage emphasized how rare that Double-A-to-Majors jump has become in modern rosters.

From the Giants’ perspective, Borucki’s release also simplifies the bullpen picture as the club continues to manage a developing roster during the season. While the Giants’ transactions show Cox taking the roster spot created by the move, Borucki leaving means any team that signs him will be doing so without a current Giants option attached. For Cox, the path now moves from minor league production to staying productive against major league pitching, where the same tools that drove his Richmond results have to translate quickly.

What to watch next is whether Cox can hold onto regular playing time, whether San Francisco’s promotion strategy becomes more common, and whether Borucki draws interest from a contender or a rebuilding club looking for left-handed bullpen depth. With Cox already credited for immediate impact in his first at-bat and speed on the basepaths, his next stretch should help determine if this is a one-week burst or the start of something longer inside the Giants’ lineup plan.
