Jake Casey is running wild in the Arizona Fall League. The Blue Jays prospect is tied for the league lead in steals after just five games.

He hasn't been caught yet. The bat has been slower, with a .125 average so far for the Mesa Solar Sox.

It's starting to turn. After going hitless in his first three games, he's collected two hits over his last two, including a homer.

"Obviously, you don't want to go off results here," Casey told MLB.com last week. "I think it's more just how I can learn and get better everyday."

The speed is what he's leaning into. "I feel like I'm understanding I have a really elite tool of speed," he said.

That fits the organization's priorities. Farm director Joe Sclafani has said base-running and base-stealing were a major focus in player development this year.

A 12-homer stint at Vancouver is the bigger story

His path has been quick. Toronto drafted the son of former big-leaguer Sean Casey in the 15th round in 2025, 442nd overall, out of Kent State.

He reached base at a .439 clip over 23 games with Single-A Dunedin to close that summer.

Then came High-A Vancouver in 2026. In 57 games, he drove in 52 runs.

He added a .373 OBP and swiped 10 bases in 12 tries, then helped the Canadians win the Northwest League title.

The steals will grab the headlines, but the power should grab the front office's attention. That kind of High-A pop from a 15th-round pick won't stay at No. 23 on MLB Pipeline's list for long.

Is the .244 average at Vancouver a concern? A little, but on-base skills, pop and speed together make a profile clubs chase.

Most prospects arrive with one loud tool. He's walking around with three, and the speed just happens to be the loudest.

He knows what's next. "I just want to learn how to be a better baserunner and defender," he said.

The Blue Jays need outfield help that comes cheap and young. The 23-year-old has a month in Arizona to make sure his name is part of that conversation heading into spring.
