Boston Celtics forward Jayson Tatum may be beloved by sports fans in Beantown, but that does not necessarily mean that he shares with them their passion for the Boston Red Sox. Born in St. Louis, Tatum grew surrounded by St. Louis Cardinals diehard fans, so naturally, it’s also the same baseball team where his allegiance lies in.

Tatum was in St. Louis on Friday to catch the first of the three-game series between the Cincinnati Reds and the Cards at Busch Stadium. He’s not there to just view the game from the stands, though. He was also there to throw the ceremonial first pitch.

Here is a clip of the Celtics’ young star taking to the mound and throwing the pitch.

Well, it’s not exactly a blazing fastball or a wicked curveball that Tatum threw, but at least the ball found the catcher’s mitt, unlike pitches hurled before by fellow NBA figures Michael Jordan and John Wall.

The sad part, though, of Tatum’s trip to Busch Stadium was that the Cards lost to Cincy, 9-1, as St. Louis’ bullpen just could not get it together, as the team’s relievers doubled starter Carlos Martinez’ total of three earned runs.

The Cards will look to win the next two games at home against the Reds before the MLB’s regular season takes a rest to give way for the All-Star break.
