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.

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.

Rich Hill isn’t done trying to play Major League Baseball just yet. The 45-year-old left-hander, who was first drafted into pro ball in 1999, has signed a Minor League deal with the Royals, the team announced on Tuesday.
