#10 Jason Marquis SP
Here we have another case of “what could have been”. This player was probably the most frustrating player on this list, as we all thought Marquis could have become so much more than what he eventually was.
Marquis was drafted by the Atlanta Braves with the seventh pick in the first round of the 1996 June Amateur Draft, and had four uninspiring seasons with the Braves. Marquis was included on the blockbuster deal that sent Adam Wainwright, Ray King, and him self to the Cardinals for J.D. Drew and Eli Marrero.
Marquis spent three seasons as a Cardinal and while he may have won 42 games in those three seasons, Marquis had an ERA of 4.60 and a FIP of 5.12 (fourth worst in Cardinals’ history). Most importantly, Marquis pitched with some of the best pitchers in Cardinals’ history and the master mind Dave Duncan and never fuller realized what he could have become.
Embarrassingly in the same era, Jeff Suppan finished with an ERA under 4.00 for the Cardinals, while Marquis dabbled in mediocrity finishing with a 2.0 fWAR in his career as a Cardinals’ hurler.
After the 2006 season in which Marquis was left out of the playoff rotation, Marquis left as a free agent and has been apart of eight different teams since leaving the Cardinals, most recently pitching for the Reds last season, amassing a 6.46 ERA and -0.1 fWAR.
