Late last week, 37-year-old third baseman Aramis Ramirez officially announced his retirement. It was a decision he had already stated publicly, but he confirmed it once the World Series ended. As quoted by Enrique Rojas of ESPNDeportes, Ramirez reiterated the decision on the radio last Thursday:

"What I said in the spring training is official. I already played my last season in the majors and left the game," the third baseman said to the radio program "Grandes en Los Deportes" on 102.5 FM in Santo Domingo.

"After 18 years in the majors and more than half of my life playing baseball, I want to be with my family and do some of the things I like," Ramirez said.

Ramirez, reacquired by the Pittsburgh Pirates for their late-season stretch run, appeared in the NL Wild Card Game as his last official activity as an MLB player.

Ramirez, who split his career among the Chicago Cubs (nine years), Pirates (seven years, including his return engagement in 2015) and the Milwaukee Brewers (4 years), was a solid, consistent offensive presence.

He finishes with a line of .283/.341/.492 with 386 home runs and 1,417 runs batted in for his career. A three-time All-Star, Ramirez posted an OPS of .800 every season of his career between 2004 and 2013 except one, a further testament of his offensive prowess.
