Toronto Blue Jays Prospects: Aaron Parker Wins AFL Home Run Derby

Congratulations are in order for Toronto Blue Jays prospect Aaron Parker, who won the Arizona Fall League's Home Run Derby on Saturday night despite being a late addition to the event.

Parker was in the event alongside some of the best prospects in baseball, including St. Louis Cardinals prospect Tai Peete, who has had a massive 2026 since being traded to St. Louis from the Seattle Mariners. He beat Peete in the finals and hit 19 home runs in total, the most of any competitor. 

If you're not familiar with Parker until now, then we've got you covered.

Not even ranked in the Top 30 of Jays prospects by MLB Pipeline, Parker was drafted in the sixth round of the 2024 MLB Draft out of UC Santa Barbara. Drafted as a catcher, he's also working in the outfield now, which could impact his ability to get to the big leagues sooner.

He's 23 years old and features immense power. He hit .253 this season at Double-A New Hampshire with 19 homers and 48 RBIs, and he did all that in just 87 games. In 174 career minor league games, he has 32 homers and 98 RBIs.

Well, as a catcher, his pathway to the big leagues seems limited. Alejandro Kirk is one of the leaders of the Jays and he's one of their key bats. Brandon Valenzuela made his major league debut in 2026 and ended up as a finalist for the Gold Glove Award, so the team figures to have him reprise his role as a backup.

Of course, injury could open the door, but his best chance to make an impact is an outfielder. Right now, the Jays feature three left-handed prospective starters in Nathan Lukes, Brett Bateman and Addison Barger.

We've said all along that the team needs a right-handed hitting outfielder to balance things out and with the decline of Myles Straw's option, perhaps Parker can be that guy soon enough.

He probably wouldn't be ready to start the season on the Opening Day roster, but he could be an option in 2027.

Parker's big weekend continues on Sunday (8 p.m. ET) as he'll play in the Arizona Fall League All-Star Game. Also joining him are Blue Jays prospects Jake Cook and Jake Bloss.

The game will air on MLB Network.
