Seattle Mariners Top 30 Prospects: 25-21, Finally Some Bats
After the first group of 5 in our Seattle Mariners prospect ranks was heavy in the way of right-handed relief pitchers, today’s list is heavy on the offensive side of the game.
If you missed our first group of Mariners prospect ranks, numbers 30-26, you can check it out here. Also, if you need a refresher on our process, you can click here. As a reminder, there are a number of players who could easily slide into this portion of the list, and we listed a few of those prospects who fell just outside the Top 30 right here.
Just as a reminder, in addition to the profile we are giving, we will also be grading tools on the standard 20-80 scouting scale. 20 is well below-average and an 80-grade is Hall of Fame level. We also have a probability rating on a 1-5 scale. 1 is the riskiest type of prospect and a 5 is a sure-fire, MLB starter or reaches their ceiling. With that in mind, let’s get started.
25. Joe DeCarlo, Catcher
Joe DeCarlo has been in the Mariners organization for quite some time. The teams second round pick way back in 2012, DeCarlo was drafted as a prep third baseman. In 2017, Seattle moved DeCarlo to catcher after he was stagnated at third, and the move has made him a prospect worth watching.
The right-handed hitter has made strides as a defender and now may profile as an offense-first catcher. Since his move to catcher, DeCarlo has held steady at the plate, slashing .246/.339/.440 in AA Arkansas. He followed up his solid 2018 with a stint in the Arizona Fall League where he slashed .262/.418/.333.
The Mariners are believers that DeCarlo has a future as at least a backup catcher, and have invited him to Spring Training this year to compete for the backup spot. When drafted, DeCarlo was thought to be a 25 home run power bat. He never quite reached that level, but now, as a catcher, he won’t have to.
