Left-handed pitcher Alex Wood posted a long message on social media Friday announcing his retirement after 12 major league seasons that included a World Series title with the Los Angeles Dodgers in 2020.

Wood, 34, began his post on Instagram by saying he had "immense gratitude" following a career in which he was an All-Star selection in 2017 and reached the postseason seven times.

"I never could've imagined it would turn out this way," Wood wrote.
