For the most part, the Seattle Mariners have had a ton of bright spots in their minor league systems. Most of the team’s top prospects have excelled this season, with the likes of Julio Rodriguez, Noelvi Marte, Emerson Hancock, and others flashing the abilities that make them such highly regarded youngsters.

And it’s not just the stars. Players like Cade Marlowe and Carter Bins have broken out in big ways, and have come on to the radar of fans as potential contributors down the line. As a matter of fact, finding three prospects that have been disappointing was challenging. This says a lot about how well the front office has stockpiled depth throughout the system, and how many draft picks and international signings they appeared to have hit on.

But when you have four teams full of prospects, there are going to be guys underperforming. The good news is that most of the guys struggling are borderline guys that didn’t project to have a lot of upside to begin with. And even the guys who may be struggling on the surface, such as Adam Macko (6.23 ERA) have tremendous underlying stats (16.62 K/9, 2.71 FIP). That doesn’t constitute struggling necessarily, more so some bad luck and adapting to the professional levels.

That all being said, there have been some guys the Mariners had hoped for that haven’t performed. Whether it’s because of age, luck, or inexperience these three guys have disappointed to some level over the course of the young season. Here are three Mariner prospects that have disappointed thus far into the 2021 season.
