Neftali Feliz began his baseball career with the Texas Rangers in 2009, playing over 20 games. Impressed by his performance, the Rangers appointed him as their closer early in the 2010 season. Feliz made it to the All-Star Game and won the Rookie of the Year award, recording 40 saves and leading the league with 59 games finished. He continued his success in 2011, recording 34 saves. However, he was moved to the rotation, but the experiment failed due to a sprained UCL that led to Tommy John Surgery. He missed most of 2012 and 2013 but managed 13 saves in 2014. Unfortunately, his performance declined, and he played for four different teams (Detroit, Pittsburgh, Milwaukee, and Kansas City), with the latter releasing him in 2017.

Feliz struggled in the Minors, bouncing between various organizations after being released by the Royals. He made a comeback in 2021, playing five games split between the Dodgers and Phillies. However, it is unlikely that he will be included on the ballot in 2027.
