Toronto Blue Jays prospect Aaron Parker put an exclamation point on his breakout 2026 season on Saturday night under the lights in Arizona.
The 23-year-old won the Arizona Fall League Home Run Derby at Salt River Field in Scottsdale, emerging victorious from the field of eight after beginning the night as the No. 7 seed.
Parker actually wasn't even supposed to be among the competitors, but was announced as a last-minute replacement for Los Angeles Dodgers infielder Chase Harlan earlier Saturday.
"It feels great," Parker told the broadcast after the win. "Got the call at 10:30 last night. Thankfully, I was up, and it was a no-brainer."
Blue Jays minor-league hitting coach Jacob Caples served as Parker's pitcher for the Derby.
A sixth-round pick of the Blue Jays in 2024, Parker began the evening by knocking off the second-seeded Alex McCoy across two rounds. He launched 12 homers (seven in the preliminary round and five in Round 1) to best McCoy's seven blasts and advance to the semifinals.
The five-foot-seven Parker continued rolling from there, even after finding himself down to his last out in the next round. Facing elimination, he launched three consecutive dingers to finish with five and take down Kansas City Royals prospect Brooks Bryan in the semis.
Parker then made quick work of St. Louis Cardinals utilityman Tai Peete in the finals, hitting the two homers he needed on just three swings to claim the Derby crown.
He clinched his victory in style by launching a 477-foot tater to left-centre field before receiving a water shower from his teammates on the sidelines.
"I'm pretty exhausted," Parker said in his walk-off interview. "It's similar to the end of the game for me. I swing as hard as I can every time I step into the box."
A UC Santa Barbara product, Parker has starred through his 12 games of action in the AFL. He owns a .994 OPS with two homers, 13 RBIs and eight steals for the Mesa Solar Sox. The showing earned him a spot on the American League Fall Stars Game roster — alongside Blue Jays teammates Jake Bloss and Jake Cook — in the showcase that goes Sunday night at 8 p.m. ET.
Parker played his entire 2026 season with the Blue Jays double-A affiliate in New Hampshire, where his power stroke was on full display.
He finished tied for third among all Toronto prospects with 19 homers, needing just 87 games to reach that mark while slashing .253/.347/.467 with 12 stolen bases and 48 RBIs.
Although he was drafted as a catcher and has spent the majority of his minor-league career behind the plate, Parker began taking reps in left field towards the end of the regular season. It's something he has continued to work on this fall in Arizona — where much of his time defensively has been spent in the outfield — as he looks to put himself on the Blue Jays' radar for the future.
Something his performance on Saturday will surely help with, as well.
