Ranking the farm systems position by position: Catcher

Using John's rankings, I decided to start ranking reach system position by position starting with catcher.

1.Blue Jays
Travis D'Arnaud(B+)
AJ Jimenez(B-)
Carlos Perez(C+)
Santiago Nessy(Other)

Jays have three strong prospects in full season ball and a fourth with some potential.

2.Mariners
Jesus Montero(A)
Tyler Marlette(C+)
John Hicks(Other)
Jack Marder(Other)

Montero is such a big prospect that he puts the Mariners in second on this list.

3.Yankees
Gary Sanchez(B+)
Austin Romine(C+)
JR Murphy(C+)
Isaias Tejada(Other)

Sanchez has some elite potential and both Romine and Murphy are strong prospects as well.

4.Reds
Devin Mesoraco(A-)
Tucker Barnhart(C)

Mesoraco is one of the best prospects in the game and that puts the Reds high on the list.

5.Padres
Yasmani Grandal(B+)
Austin Hedges(B-)
Jason Hagerty(Other)

Grandal is finally out of the shadow of Mesoraco. It's likely that he's going to be a strong regular in San Diego. Hedges was a top draft choice last year and Hagerty is a potential backup that doesn't get much hype.

6.Red Sox
Ryan Lavarnway(B)
Blake Swihart(B-)
Christian Vazquez(C+)

Lavarnway can really mash, and already has some big league success. Swihart is another top draft choice from last year, and Vazquez also has potential.

7.A's
Derek Norris(B)
Josh Donaldson(C+)
Max Stassi(Other)
Beau Taylor(Other)

Norris is a three outcome hitter, but is still a pretty solid prospect. Donaldson is a potential backup that gets overlooked by many. Stassi is a former top prospect who has seen his stock fall a bit.

8.Giants
Tommy Joseph(B-)
Andrew Susac(B-)
Hector Sanchez(C+)
Alex Burg(Other)

Defensive questions follow Joseph, but the youngster can has good pop in his bat. You also can't forget about top draft prospect Susac or Sanchez, who broke out last year.

9.Rockies
Willin Rosario(B-)
Jordan Pacheco(Other)
Will Swanner(Other)

Rosario is among the top catching prospects in baseball, although his stock has fallen from a year ago. Pacheco could end up at third base, but could be in the big leagues this year. Swanner is far away, but he has big power in his bat.

10.Braves
Christian Bethancourt(B-)
Evan Gattis(Other)

Bethancourt is a bit of an enigma- all talent, little production. Still he's very young and took a step forward last year in Low-A. Gattis is older but shouldn't be written off after a monster year last year.

11.Phillies
Sebastian Valle(B-)

Valle is a strong prospect, but not elite. The Phills fall to #11 because they don't have anyone other than him on John's list.

12.Indians
Chun Chen(C+)
Jake Lowery(C+)
Eric Haase(Other)
Alex Lavisky(Other)

Chen is an all-bat prospect, but has a strong enough bat to be a contributor. Lowery is a solid prospect on his own, though he doesn't get much attention. Lavisky is quite raw, but he has some real potential.

13.Rangers
Jorge Alfaro(C+)
Tomas Telis(Other)
Yefry Castillo(Other)

Personally I like the Rangers better than the Indians, but per John's rankings I had to use this order. Alfaro is a potential All-Star, but he is only in short-season ball. Telis is another kid with some potential buried in a system full of kids with potential.

14.Rays
Oscar Hernandez(C+)
Lucas Bailey(Other)
Justin O'Conner(Other)
Stephen Vogt(Other)

Hernandez is a youngster who put up big numbers last year in the VSL, but we need to see him in America before ranking him higher. Bailey and O'Conner were each high draft picks, but have struggled to adjust to the minors- although the same can be said about Devin Mesoraco two years ago.

15.Marlins
JT Realmuto(B-)
Austin Barnes(Other)
Austin Brice(Other)
Jobduan Morales(Other)
Kyle Skipworth(Other)

Realmuto had a strong season last year in his first year with a full-season club. None of the others really strike you as true prospects, although despite not producing, Skipworth has some talent.

16.Tigers
James McCann(C+)
Rob Brantly(Other)
McCann was a solid college draft choice last year, and Brantly was a pick two years ago.

17.Pirates
Tony Sanchez(C+)
Ramon Cabrera(Other)
After a down year, Sanchez saw his stock drop significantly. Cabrera is small, but hit well in High-A last year.

18.White Sox
Kevan Smith(C+)
Mike Blanke(Other)
Smith, the former Pitt football player, should move quickly through the system due to being an older prospect. Blanke is a bit of a sleeper.

19.Dodgers
Gorman Erickson(C+)
Tim Federowicz(Other)
Pratt Maynard(Other)
Chris O'Brien(Other)
Erickson isn't very well known, but is still solid. Federowicz is a defensive catcher who could be a top backup. Both Maynard and O'Brien were highly thought of last year in the draft.

20.Royals
Cam Gallagher(C+)
Gallagher was a big bonus high school draftee, but has some real potential.
21.Cubs
Wellington Castillo(C+)
Neftali Rosario(Other)
Castillo would be best as a backup, but could eventually get a chance to start.

22.Cardinals
Cody Stanley(C+)
Tony Cruz(Other)
Robert Stock(Other)
None of the Cards have much chance of being more than a backup.

23.Nationals
David Freitas(C+)
Freitas doesn't really impress me as a "C+" prospect.

24.Astros
Chris Wallace(C)
I like Wallace at a "C" grade.

25.Orioles
Gabriel Lino(C)
Lino has some potential.

26.Angels
Carlos Ramirez(C)
Abel Baker(Other)
Neither of the Angels prospects excite me.

27.Brewers
Martin Maldonado(Other)
Maldonado has a better shot to be a big league backup than Hermann, so the Brewers rank a bit higher.

28.Twins
Chris Hermann(Other)
Hermann isn't likely to make the bigs.

t-29.Diamondbacks

t-29.Mets
