Griffin Conine Bio
Griffin Riley Conine, born on July 11, 1997, is an American professional baseball outfielder currently playing for the Miami Marlins of Major League Baseball (MLB). He is the son of former MLB outfielder Jeff Conine, a two-time All-Star known as “Mr. Marlin” for his long association with the Miami franchise. Following his father’s footsteps into professional baseball, Griffin Conine has developed into an outfield prospect with notable power at the plate, working his way through the minor leagues before reaching the majors in 2024.
Early Life and Background
Griffin Riley Conine grew up in Fort Lauderdale, Florida, where he attended Pine Crest High School. Coming from a family with deep baseball roots, he was exposed to the game from a young age and developed his skills in the South Florida amateur circuit. In his senior season at Pine Crest, Conine posted a .341 batting average with eight home runs and 27 runs batted in (RBI), attracting attention from professional scouts.
Following his high school career, Conine was selected in the 31st round of the 2015 Major League Baseball draft by the Miami Marlins. Opting to continue his development, he did not sign with the Marlins and instead chose to attend Duke University, where he played college baseball for the Blue Devils. At Duke, he balanced academics with the demands of a competitive Division I baseball program, steadily improving his offensive profile over three collegiate seasons.
Path to Baseball
Conine’s college career at Duke University served as the foundation for his transition to professional baseball. In his first season with the Blue Devils, he appeared in 35 games and hit .205 with six RBI, adjusting to the higher level of competition. As a sophomore, Conine took a significant step forward, batting .298 with 13 home runs and 56 RBI, becoming the first Blue Devil to total 50-plus RBI in a season since Nate Freiman in 2009. His 13 home runs that year also made him the first Duke player with 10 or more in a season since Jake Lemmerman in 2010.
In his third and final season at Duke, Conine played in 63 games and hit .286 with 18 home runs and 52 RBI, further cementing his reputation as a power-hitting outfielder. During the summer of 2017, he played collegiate summer baseball with the Cotuit Kettleers of the Cape Cod Baseball League, where he was named a league all-star and the league’s Outstanding Pro Prospect. These performances across all levels helped position him as a legitimate professional prospect heading into the 2018 draft.

Toronto Blue Jays System (2018–2020)
Conine was drafted by the Toronto Blue Jays in the second round, with the 52nd overall selection, of the 2018 Major League Baseball draft, and signed on June 20 for a $1.35 million signing bonus.

The Blue Jays later traded Conine to the Marlins as the player to be named later in their August 31, 2020, trade for Jonathan Villar. He did not appear in any official games in 2020 due to the cancellation of the minor league season caused by the COVID-19 pandemic.

The following season, he returned to Pensacola and played in 118 games, hitting .215/.337/.435 with 24 home runs and 74 RBI.

Earlier in his career, his selection as the Cape Cod Baseball League’s Outstanding Pro Prospect in 2017 marked him as a rising talent in the amateur ranks. His 36-home run minor league season in 2021 further established his power-hitting credentials, while his rapid return from a serious shoulder injury in 2025 reflected his resilience and dedication to the game.

2025 Season Performance
Griffin Conine’s 2025 season was disrupted by a significant injury early in the year. On April 19, 2025, it was announced that he had suffered a dislocated left shoulder, leading to his placement on the 60-day injured list the following day. He underwent season-ending left shoulder surgery on April 29, abruptly halting what had been a productive start to his second major league campaign.
Before the injury, Conine had been performing well at the plate in limited major league action, batting .352/.352/.438 with one home run and seven RBI across 20 appearances for the Marlins. His strong early-season numbers suggested a potential breakout in his sophomore year had the injury not intervened. The Marlins’ medical and training staff supported his recovery, and Conine was ultimately activated from the injured list on September 22, returning to the active roster for the final stretch of the season.
Looking ahead, Conine is expected to fully recover and compete for a more established role in the Marlins’ outfield. His combination of power, plate discipline, and pedigree makes him an intriguing piece of the organization’s long-term plans. With a full offseason of rehabilitation behind him, Conine will aim to build on his late-2025 return and establish himself as an everyday contributor for Miami in the seasons to come.
