Longtime Major League Baseball reliever and free agent David Robertson could become an option for a team in the second half of the season.

Life is defined by constant change, but David Robertson finding his way onto a team's bullpen is seemingly inevitable.

The veteran righty last threw to a sub-2.00 ERA in 2017, something he accomplished twice, but his 2.91 career ERA still stands as a testament to his reliability over the past few decades. Today, he still waits in free agency. However, it might not be long until he finds himself in a new uniform — or possibly an old one.
