No player selected by the Marlins have made it to the majors after getting selected in the 34th round, at least not yet. It’s not impossible though. Nine players chosen in the 34th round through the past 10 drafts have made it that far, led by right-handed pitcher Julio Lugo.
Here’s the Marlins haul during that time.
Steven Dennison was a six-foot-seven lefty from Centennial, CO. Picked 1037th overall, he was 10-7 with a 5.95 ERA for the Division 3 Wheaton College Thunder. Unsigned by the Marlins, Dennison joined the Houston Astros organization in 2011, and pitched in 14 games for their rookie level affiliate in the Gulf Coast League, the GCL Astros.
