Giants Option Dylan Smith to Triple-A Sacramento After Detroit Trade

The San Francisco Giants added a potential late-season bullpen weapon on Monday, acquiring right-hander Dylan Smith from the Detroit Tigers for cash considerations and immediately optioning the 25-year-old to Triple-A Sacramento. The move came packaged with two significant departures: outfielder Luis Matos was traded to the Milwaukee Brewers, and infielder Tyler Fitzgerald was designated for assignment to clear Smith's spot on the 40-man roster.

Smith arrives in Sacramento as a legitimate MLB-ready arm, not a depth afterthought. His 2025 major-league debut with Detroit produced a 1.38 ERA across 13 innings, a number that would have ranked among the Giants' most effective relief options had he been on their roster. The immediate option to Sacramento reflects roster math rather than doubt in his ability: Smith retains Minor League options, giving San Francisco the flexibility to shuttle him between Sacramento and the big-league club as bullpen demands dictate throughout the season.

Detroit, meanwhile, was backed into a corner by its own roster construction. The Tigers designated Smith for assignment just before Opening Day after adding a young player to the 40-man roster to shield them from the Rule 5 Draft. Scott Harris, the former Giants general manager now serving as Detroit's president of baseball operations, made clear the decision was logistical rather than evaluative. "I think Dylan has the talent to be an effective reliever in this game," Harris said, via the Detroit Free Press. "For us right now, given the young player that we added to our 40-man [roster] to protect them from the Rule 5 [draft], and given the spring that a number of guys on our 40-man had, we had a tough choice."

That tough choice opened the door for San Francisco to acquire an 18th-round sleeper. Smith was originally drafted by the San Diego Padres in 2018 and spent years building toward his 2025 breakthrough, when he posted a 2.27 ERA with 57 strikeouts and just 11 walks in 39 2/3 innings across four levels of Detroit's system. At Triple-A Toledo specifically, he made 12 relief appearances and struck out 22 batters in 12 1/3 innings. His arsenal centers on a sinker that has touched 96 mph, paired with a four-seam fastball and a mid-80s slider, though he has been working to consolidate those offerings into a coherent attack.

Smith's arrival makes him the second reliever San Francisco has added in 10 days. Left-hander Ryan Borucki, signed to a one-year Major League deal on March 21, gave up one run over 1 2/3 innings across two appearances in the Giants' opening series against the New York Yankees. With Borucki already occupying a roster spot, Smith's path to a recall runs through sustained performance at Sacramento: maintaining the walk discipline he showed across four minor-league levels last year and leveraging that 96 mph sinker for the ground-ball outs that project well in a late-inning role.

The reshuffling also closed a chapter on two former Giants prospects. Fitzgerald, who batted .154 with a .592 OPS in only 15 games for San Francisco over the final three months of last season, had already been assigned to Sacramento to begin 2026. With Luis Arraez entrenched at second base and Casey Schmitt and Christian Koss occupying the backup infield roles, there was no path back for Fitzgerald on the 40-man. Matos's trade to Milwaukee cleared a parallel outfield logjam.

For Smith, Sacramento is not the destination. It is the proving ground.
