Early Life and Background

Conine grew up in Fort Lauderdale, Florida, where he attended Pine Crest High School.

His performance at the high school level caught the attention of professional scouts, and he was selected in the 31st round of the 2015 Major League Baseball Draft by the Miami Marlins. However, Conine chose not to sign and instead pursued his college baseball career at Duke University in Durham, North Carolina.

Additionally, his 13 home runs marked the first time a Duke player had hit double-digit home runs in a season since Jake Lemmerman hit 10 in 2010.

Path to Professional Baseball

Conine continued his offensive production during his junior season at Duke, playing in 63 games while hitting .286 with 18 home runs and 52 RBI. His standout collegiate career earned him an opportunity to play collegiate summer baseball in 2017 with the Cotuit Kettleers of the Cape Cod Baseball League, a prestigious summer circuit known for developing professional prospects. His performance with Cotuit was exceptional, as he was named a Cape Cod Baseball League all-star and received the league’s Outstanding Pro Prospect award, solidifying his status as a top draft prospect.
