Playing for the Single-A Dunedin Blue Jays on Tuesday night, Toronto Blue Jays top prospect JoJo Parker made quite the impression.

Parker, who was a first-round pick in the 2025 MLB Draft, hit his first professional home run.

He cleared a building in right field, smoking the homer at 108.3 mph. Parker is the No. 40 prospect in baseball, according to MLB Pipeline.

Here's what you need to know about him.

Still just 19 years old, Parker was selected No. 8 overall in 2025 out of the Mississippi high school ranks. He did not play in a game after getting drafted, so this is his first exposure to professional baseball.

Thus far, he's hitting .273 with a .415 on-base percentage. Through nine games, he has the home run, nine RBIs and three stolen bases.

The following comes from a portion of his MLB.com prospect profile:

Parker has a powerful left-handed swing, but he’s able to keep his hacks in control, impressing pre-Draft evaluators with the way he manages the strike zone. There was already a feel to add loft in his swing, though he tended more toward line drives, and with work from Blue Jays strength training, he could get to plus power in the future. Toronto officials already see adding muscle as a major opportunity to grow Parker’s profile.

Parker is not predicted to make his major league debut until 2029, so there's plenty that can happen between now and then.

By that point, Toronto will have cleared significant money in the form of George Springer, Kevin Gausman, Jeff Hoffman and Anthony Santander, so there's no telling what they will have spent on to potentially impact Parker's standing in the infield. 

But for now, both he and fellow top prospect Arjun Nimmala (No. 69), look like cornerstone pieces of a future infield. 

After winning on Tuesday night, the Jays enter play on Wednesday at 7-9 overall. They'll take on the Milwaukee Brewers in game two of a three-game series at 7:40 p.m. ET.

Right-hander Dylan Cease will battle against righty Chad Patrick.

Cease is 0-0 with a 2.45 ERA so far while Patrick is 1-0 with a 0.73 ERA.

Much of Toronto's season has been marred by injuries to this point, but things are finally turning a corner on that front. Trey Yesavage and Jose Berrios are both working back and could be set to rejoin the rotation soon.
