Texas Rangers third baseman Adrian Beltre announced his retirement Tuesday.”After careful consideration and many sleepless nights, I have made the decision to retire from what I’ve been doing my whole life, which is playing baseball, the game I love,” said Beltre in a statement released by the team. “I have thought about it a lot and although I appreciate all the opportunities and everything that baseball has given me, it’s time to call it a career. I have enjoyed the privilege of playing professional baseball since I was 15 years old. I have been blessed to have played 21 seasons at the highest level in Major League Baseball.” … I also have to acknowledge and thank Tommy Lasorda for believing in this young kid from the Dominican Republic when others thought I was too young to be called up to the Big Leagues.”Beltre retires leading all third basemen in RBIs and he’s third all-time among players at the position with 477 career home runs and Wins Above Replacement. In the WAR metric, Beltre is 38th all-time.Beltre spent 21 seasons in MLB and remained productive at the plate but was limited to 134 games at third base the past two seasons combined.A four-time All-Star and five-time Gold Glove winner at the hot corner, Beltre had a .286 lifetime batting average and 3,166 hits.
