Trey Mancini is coming home. The former Baltimore Orioles first baseman and outfielder will sign a one-day contract and officially retire from Major League Baseball on September 19, closing the book on a career that took him from a record-setting rookie season to a Stage 3 colon cancer diagnosis to a World Series ring with the Houston Astros.
The Orioles announced that Mancini will sign the ceremonial contract and retire as a Baltimore Oriole, according to WMAR 2 News Baltimore. The club will mark the occasion with a pregame ceremony unveiling a new, permanent sign in the dugout, and Mancini is scheduled to hold a kids-only autograph session during Fan Appreciation Weekend. A ticket package for the game includes a limited-edition hat featuring the F16HT logo, with a portion of the proceeds going to the Trey Mancini Foundation.
From Notre Dame Draft Pick to Baltimore Fixture
Mancini was drafted by the Orioles out of the University of Notre Dame in 2013 and made his MLB debut in 2016, per the station's report. He spent his first six seasons with the organization, and his rookie campaign in 2017 announced him as a star: he hit .293 with 24 home runs and 78 RBIs, finishing third in American League Rookie of the Year voting behind winner Aaron Judge and runner-up Andrew Benintendi, according to MLB.com. Over 701 games in Baltimore between 2016 and 2022, Mancini batted .270 with 117 home runs and 350 RBIs, per StatMuse.
Mancini told the station that baseball has been the focal point of his life since his parents signed him up for T-ball 30 years ago — a detail that underscores just how much the sport has defined him, long before Baltimore fans came to know him as a franchise cornerstone.
A Cancer Diagnosis That Became a Local Story
Mancini's connection to Baltimore runs deeper than box scores. He underwent treatment for Stage 3 colon cancer in 2020, receiving surgery at Johns Hopkins Hospital on March 12 of that year — the same day MLB suspended spring training because of the COVID-19 pandemic — followed by six months of biweekly chemotherapy that concluded in September 2020, according to MLB.com. He missed the entire 2020 season with the Orioles while his cancer went into remission, and the club produced F16HT T-shirts that year to benefit the Colorectal Cancer Alliance's patient and family support services. The F16HT sign has remained in the home dugout tunnel every season since, and proceeds from those shirt sales have exceeded $80,000; the sign will now be relocated within the club level archives at Camden Yards.
Sixteen months after his surgery, Mancini advanced to the final round of the 2021 MLB Home Run Derby at Coors Field in Denver, finishing as runner-up to New York Mets slugger Pete Alonso in a 23-22 finish, per MLB.com's account. That comeback earned him American League Comeback Player of the Year honors in 2021. Mancini also credited a friendship he developed starting in 2018 with Mo Gaba, a 14-year-old Baltimore sports superfan who died in July 2020, with reshaping his outlook and emotional maturity, as detailed by PressBox.
A World Series Ring and a Long Road Back
The Astros traded for Mancini in August 2022, and he helped Houston win the World Series that year. In Game 5 of that series, Mancini entered off the bench and made a key unassisted diving play at first base on a groundout by Kyle Schwarber in the bottom of the eighth inning, preserving a 3-2 lead in the Astros' victory over the Philadelphia Phillies, according to Sports Illustrated.
His path to a final retirement wasn't a straight line. Mancini spent 2024 and 2025 working back through Triple-A before making a brief return to the majors with the Los Angeles Angels on June 8, 2026 — his first MLB game in 1,043 days. He went 3-for-4 with an RBI in that return, per MLB.com's press release, before appearing in five total games and announcing his retirement on August 18. Over eight major league seasons with Baltimore, Houston, Chicago, and Los Angeles, Mancini finished with a .263 average, 129 home runs, and 404 RBIs across 836 career games, according to Baseball-Reference.
Why His Story Still Resonates
Mancini's diagnosis at age 28 landed him squarely within a troubling national trend. Colorectal cancer incidence among adults under 50 in the United States has been climbing roughly 3% annually, making it the leading cause of cancer death among men under 50 and the second-leading cause among women under 50, according to a March 2026 report from the American Cancer Society. That backdrop is part of why Mancini's recovery and comeback carried such weight beyond Baltimore's baseball fans.
The Trey Mancini Foundation, formed in 2021, works to address food insecurity and support children and families battling severe illnesses and financial hardship, according to Cause IQ. Proceeds from the September 19 ticket package will help fund that mission, tying Mancini's on-field farewell directly to the community work that has defined his post-playing life.
