San Francisco Giants catcher Buster Posey made it official Thursday, announcing his retirement after 12 years, three World Series titles and a Most Valuable Player award.

The central theme to Posey's farewell was family.

"It's a lot more than just winning or losing games, although the wins do feel a lot better, it's about the time spent with family, the countless nights and days pulling for your team, riding the emotions of the highs, riding the emotions of the lows, and ultimately enjoying the people that you're with along the way and making great memories together," Posey said.
