The former starting pitcher and current ESPN analyst hasn't stepped on an MLB mound since 2008, but according to Jerry Crasnick of ESPN.com, he was encouraged after watching Los Angeles Dodgers reliever Paco Rodriguez's delivery during the 2013 playoffs.
Mulder spent the first five years of his career with the Oakland Athletics. During that time, he amassed an 81-42 record and a 3.92 ERA in 1,003 innings. He was named to two All-Star teams (2003 and 2004) and finished second in the 2001 Cy Young voting.
A trade to the St. Louis Cardinals marked the beginning of his career decline, however. He made 32 starts his first year in St. Louis in 2005, going 16-8, but would make just 21 more over the next three seasons. Injuries forced him out of the game in 2008 and led to his retirement in 2010.
For those who forget how good Mulder was in his prime, HardballTalk's Matthew Pouliot noted how well the former ace began his career.
It will be interesting to see how successful the comeback attempt is. Mulder was always known for his great command, rather than overpowering opposing hitters, so it's not as if he'll have to completely change what kind of pitcher he is.
If a 49-year-old Jamie Moyer can find a job, you'd have to believe somebody will take a flier on Mulder this offseason.
