In May, Simpson raved that the boy is"naturally gifted” at the sportafter he was “picked as an All-Star” player.

“When Ace was in my belly I told everyone and anyone who’d listen that he would dominate a baseball field when he was old enough and would more than likely never ever end up putting the bat down…so far my intuition was correct,” she began in an Instagram post.

“This kiddo is SO naturally gifted, laser focused, instinctual, bats the ball out of the park, pitches strike outs, and owns his confidence with a humble grin,” Simpson shared, posting a photo of herself and Ace at a baseball game.

“Ace is honestly as good as it gets and as ready as ever to continue exceeding with pure excellence,” she added. “I am so proud of my only son. when mama knows she knows…”

A month later, Simpson shared with her followers that Ace hadhit a home run at his championship gameand clinched the win for his team.

“My baseball stud won the championships with a hitting a home run against an undefeated team at the end of the ballgame,” she gushed at the time. “He told me that he saved that hit for that moment so the team was caught off guard. Now that is athlete mentality if I do say so myself…and he is only 7.”
