Over the years, the Toronto Blue Jays have developed plenty of prospects who have gone on to become significant difference makers at the major league level. Obvious success stories in the past include stars such as Carlos Delgado, Roy Halladay and, more recently, Vladimir Guerrero Jr.
And while there are plenty of Jays prospects who have gone on to have success, there are also plenty of prospects who failed to reach their full potential whether that be with the Jays or elsewhere. Let's take a look at four former Blue Jays prospects who have flamed out since leaving Toronto.
4 former Blue Jays top prospects who look like disasters after leaving Toronto
INF Jordan Groshans

Toronto selected Groshans in the 2018 MLB Draft, and he was once thought of as the Blue Jays' third baseman of the future. Groshans even drew comparisons to former Blue Jays MVP Josh Donaldson thanks to a profile based on his ability to get on base and hit for average and power.
However, he never got the chance to play for the Jays’ big league club, as he was traded to the Miami Marlins at the 2022 trade deadline in exchange for pitchers Anthony Bass, Zach Pop and minor league catcher Edward Duran.
Groshans hasn’t had much success since leaving the Jays’ organization, as he hit .262 with one home run and two RBI with the Marlins in 2022.

He failed to reach MLB with Miami in 2023 and was designated for assignment in February 2024. The Yankees acquired him on waivers but designated him for assignment less than a month later, where he settled with their Triple-A team. They then traded him to the Oakland Athletics, and he signed with the Royals as a minor league free agent in the offseason.
He's now 25 and is the prototypical Quad-A player; he's too good for the minors but not good enough to stick in MLB.
Groshans has been a huge flop given the high expectations that many teams had in him.
OF Anthony Alford

The Blue Jays drafted Alford in the third round of the 2012 MLB Draft, and his prospect ranking quickly grew in the years that followed. MLB Pipeline had him as a top-three prospect in the Jays' organization from 2016 to '18. There was even some buzz that he could become a five-tool player in MLB not dissimilar to Vernon Wells.
The promising outfielder made his MLB debut in 2017, and recorded his first MLB hit in a game against the Milwaukee Brewers.

However, a slew of injuries would rob him of much of that promise, as Alford only played in 46 games with the Blue Jays in four-and-a-half seasons before he was designated for assignment in 2020.
The Pirates scooped him up on the waiver wire, and he played in 56 games with the Pirates in 2020, '21 and '22.
He's since spent time in the minors with the Cleveland Guardians and Cincinnati Reds, along with some time spent in the KBO and Mexican League.
He's currently a free agent.
