Baseball is a sport where players try to hang on for as long as possible. We have seen many players play past their prime and even into their 40s. Some cannot let the game go, even though they are not the players they once were.

The Kansas City Royals signed 45-year-old pitcher Rich Hill to a minor-league contract. It would be his 14th MLB team.

Hill, 45, would be the oldest player in MLB if he reaches the big leagues. If he pitches for the Royals, he'll tie the MLB record for teams.
