Remember when San Diego turned into Slam Diego this summer after the Padres hit a grand slam in a record four straight games? It appears Padres superstar Fernando Tatis Jr. is up to some other Slam Diego activities this offseason.

In a video shared by Héctor Gómez, Tatis is seen dunking a basketball in a gym for a different kind of slam.

Tatis, who finished fourth in NL MVP voting this past season, one place behind teammate Manny Machado, has been posting various workout videos and updates to his Instagram in the offseason, including traditional weightlifting. But there have been plenty of surprises, too. Over the weekend, he had a video of himself meditating underwater in a lagoon in the Dominican Republic.
