Adell entered each of the past two seasons as a consensus top-ten prospect leaguewide. Selected out of high school in the first round of the 2017 draft, he has certainly hit his ceiling as a prospect. Now we’ll see whether he can do so as a major leaguer.
Given the timing of the promotion, Adell will not be able to accrue a full season of MLB service this year. He’s now on track to reach free agency after the 2026 season. If he holds down a roster spot from this point forward, Adell will surely qualify for arbitration in advance of the 2023 season as a Super Two player.
The 21-year-old Adell has generally thrived on his way up the ladder. He didn’t impress at Triple-A last year after a late-season promotion, but he showed well in the Arizona Fall League and doesn’t really have anything left to prove. All told, Adell owns a .298/.361/.518 batting line in the minors.
Most prospect watchers expect Adell to grow into added power. He’s already driving the ball all over the field and has the wheels to take extra bases. That speed also serves Adell well in the outfield, where he also possesses a big arm.
There’s really not much not to like. Adell does have some swing and miss but not so much that it’s considered a likely hindrance. As with any prospect, there’s a wide variance of potential outcomes. But Halos fans have every reason to be excited to welcome another premium talent to the roster.
