6. Ryan Zimmerman
Zimmerman is one of a trio of Washington Nationals’ stars who chose to opt out. The 35-year-old is a 15-year Nationals’ veteran. However, despite the longevity of his time in Washington, he still chose to put his family first. But he had a very good reason for that decision.

First of all, his mother suffers from multiple sclerosis and is in the high-risk category. In short, Zimmerman does not want to endanger her life. He also has a three-month-old baby who he would not be able to see for weeks. Last season, he batted .257 with six home runs and 27 RBIs in 171 at-bats, including a dramatic home run in Game One of the World Series.
