St. Louis Cardinals legend Albert Pujols' performance in the second half of the season proved that he still has a lot left in the tank, but he won't be backing off his retirement plans.

According to MLB Network's Mark Feinsand, Pujols officially signed his retirement papers on Monday, solidifying the end of his playing career after 22 seasons.

Pujols announced in March that the 2022 season would be his last. He returned to St. Louis, the franchise with whom he spent the first 11 seasons of his career, for his final year after spending time with the Los Angeles Angels and Los Angeles Dodgers.
