The San Francisco Giants have made a notable roster change by designating right-hander Lou Trivino for assignment and promoting southpaw Kyle Harrison to their active roster for the first time in the 2025 season. The move creates a 40-man roster spot with Trivino’s dismissal, even though no immediate transaction appears on the horizon to fill that vacancy.
Trivino had a modest performance, delivering a scoreless inning during the Giants’ recent 9-3 victory over the Rockies. However, his season ERA stands at 5.84 across 12 1/3 innings, coupled with below-average strikeout and walk rates, pointing to a disappointing return following a seriously challenging time recovering from Tommy John surgery and other arm issues. His only appearances in the past two seasons were limited to the minor leagues, and lingering injuries hampered his attempts to return to the major leagues until now. Trivino’s contract with San Francisco guaranteed him a salary of $1.5 million for this season.
As for Kyle Harrison, after his last Triple-A start on April 30, he may be slated to take over in the Giants’ rotation soon, especially with current pitcher Landen Roupp struggling with a 5.10 ERA over six starts. Additionally, Jordan Hicks, who has a 6.03 ERA, is also in a vulnerable position. The Giants could view Harrison not just as a potential starter but also as a valuable bullpen asset, offering depth and a second left-handed option alongside Erik Miller.
Over his appearances in Major League Baseball, Harrison has recorded a 4.47 ERA, along with a 22.5% strikeout rate and a 7.8% walk rate. Despite these numbers not being outstanding, Harrison is viewed as a significant prospect for the Giants’ future. His promotion hints at the organization’s commitment to developing him further and testing his abilities against top-tier hitters, while also factoring in his previous season’s challenges including a shoulder impingement and a viral illness during Spring Training that delayed his progress.
The Giants’ decision to bring up Harrison reflects their long-term strategy for building a robust pitching staff. The hope is that Harrison can emerge as a cornerstone of their rotation moving forward, showcasing the organization’s dedication to nurturing young talent amidst the challenges they’ve faced in recent seasons.
