9. Jaime Jones
The Florida Marlins expected big things out of left-handed outfielder Jaime Jones. So much so in fact that they spent their 1995 first-round choice on him, with the sixth overall selection. Out of 86 players chosen by the Marlins that year, 12 reached the major leagues, but not Jones.
Randy Wynn (27.5 career WAR) was the only member of that season’s Marlins draft class to eclipse a career-WAR figure of 1.0, and Florida left him unprotected in the 1998 expansion draft, where he joined the Rays. Jones, who had his career-year in 1998 as well, unfortunately had it at the Double-A level with the Portland Sea Dogs in the Eastern League. That year, he hit .281/.363/.411 with 10 home runs and 63 RBI.
Jones remained with the SeaDogs for the following three seasons as well, hitting .202/.299/.277 in 31 contests in 2001. After sitting 2002 out of baseball entirely, he later joined the systems of the Arizona Diamondbacks and the Kansas City Royals, but never in the majors.
