Conine, alternatively known as "Niner," "Mr. Marlin" and "Conine the Barbarian," was originally drafted in the 58th round of the 1987 amateur draft by the Kansas City Royals. He appeared in 37 games over two seasons, hitting .252 with 11 RBI. The Marlins picked him up with the 22nd pick of the expansion draft.
Conine appeared in all 162 games in his "official" rookie season with Florida. He hit .292 with 12 home runs and 79 RBI, finishing third in the NL Rookie of the Year voting.
In each of his next two seasons with the Fish, Conine was an NL All-Star selectee, hitting a combined .310 with 43 home runs and 187 RBI. He was another casualty of the Huizenga-sponsored post-1997 exodus, rejoining the Royals via trade for minor leaguer Blaine Mull.
He later spent four-and-a-half seasons with the Baltimore Orioles, rejoining the Marlins for three seasons starting in 2003.
In eight seasons with Florida, Conine hit 120 home runs and 553 RBI with a .290 average. He finished out his career by rejoining first the Orioles and then the Philadelphia Phillies, the New York Mets and the Cincinnati Reds.
He currently works in the Marlins front office as an assistant to team president David Samson.
