Adam’s Disagreements – July 23th
Brennen’s Disagreements – July 24th
We have included a rough prime projection for each player as well as an estimated ETA. We tried not to include players that have cemented roles in the majors at the time of this writing, so guys like Juan Soto and Mike Soroka will not be included. Note that we place an emphasis on upside, namely power and speed guys, while also prioritizing closeness to the majors when the value is close. Feel free to ask questions or drop a comment, we are always happy to discuss! Without further ado, onto the list!

– Francisco Mejia over Danny Jansen for #1 was fairly tough to commit to as Jansen has actually out-hit Mejia both in 2017 and 2018 in numerous important metrics including wOBA and wRC+ of which Jansen ranks in a tie for first in the entire International League this year. I recently wrote an article on Danny Jansen here that explains why he should be on your radar. Mejia’s recent hot streak and better scouting grades including more game power help him retain his top catching prospect throne over Jansen for now, but it’s close. Both players should see time in the majors this year at some point.
– Zack Collins and Austin Allen both are catchers that aren’t well regarded for their defensive abilities and may be ticketed for 1st base long-term and that knocks them both down in these rankings. Overall defense shouldn’t be taken into account much in fantasy baseball rankings like these, but both players may not be able to return value at the catcher position without eligibility to play there in the future and so you have to account for that in positional rankings.
– 3 recent draftees make the top 30 list, including Joey Bart who was taken 2nd overall by the San Francisco Giants, Anthony Seigler who was taken 23rd overall by the New York Yankees, and Ryan Jeffers who was taken 59th overall by the Minnesota Twins after a standout career and UNC Wilmington in which he hit .323/.445/.620 for his NCAA career (3 seasons).
– There is a very interesting mix of younger catchers at the A-ball level that are all young and full of promise. Ronaldo Hernandez is perhaps the most interesting as he’s consistently shown a quality bat (current 149 wRC+ in 2018) and has the defensive skills to catch long-term. MJ Melendez is known as a quality defender and has plus raw power but may be limited by contact concerns. William Contreras is the younger brother of Willson Contreras who plays for the Chicago Cubs and he has consistently been above-average in his minor league career at the plate (current 123 wRC+ in 2018). Lastly, Miguel Amaya who has been one of the bigger breakout stories of the Chicago Cubs system with Amaya getting to his power more frequently while maintaining quality contact skills. It will be interesting to see how they all develop going forward!
– Garrett Stubbs has had a very nice bounce-back year at AAA as he’s currently slashing .339/.400/.474 that has been worth a 130 wRC+. The power isn’t there still, and that may always limit him but his contact skills are strong with an above-average 14.6% strikeout rate and 8.5% swinging-strike rate. He also notably has cut into his groundball rate as he’s managing a career-low 25.4% which may suggest that more power is coming.
– Alex Jackson is another notable name after being a top pick (6th overall) of the Seattle Mariners back in 2014. His 2018 season has seen him really struggle to make contact with a 30.5% strikeout rate that is supported by a very much below-average 17.6% swinging-strike rate at the AA level. He does possess impressive power upside, but contact concerns are beginning to really limit his ability to be a valuable offensive catcher.
