Eric A Longenhagen: Hey from the shade at Scottsdale Stadium as the Zags and Dons stretch for this morning’s elimination game. I’m here to see Karsten Sweum and Mikey Bell, among others. Sorry my attention will be divided but it’s conference tourney time and we’ve all just gotta do what we’ve gotta.
12:45
liljebbie10: One other question, with Esmerlyn Valdez coming up today, what are you thoughts on him? What is his upside for the Pirates?
12:46
Eric A Longenhagen: I updated his tool grades and report on The Board and on his player page. Here is a brief version:
12:48
Eric A Longenhagen: Selectivity, power, less pull ability than last year, really late on a lot of heaters so far. Bad defense. 45. Nice piece, 5-thru-7 hole bat with OBP and power. I don’t believe in the year over year improvement in his K% and still think he’s a 40 contact hitter and barely playable on defense, so not a true “everyday” guy, but still a contributing piece.
12:48
Surplus Valuez = Profits = Stolen Wages: Happy Friday. When yous were doing the Cubs list, was there any feedback that Juan Cabada may end up in the OF? Or is there high confidence for the IF?
12:49
Eric A Longenhagen: Second base but not great there.

Eric A Longenhagen: Good morning from sunny Tempe, where the temps have begun to crank a bit. Check out the Orioles list if you haven’t yet. I’m working on Pirates next, Brendan on BoSox. Good systems, all.
12:03
Jeb: How long until Seth Hernandez is the #1 pitching prospect in baseball?
12:03
Eric A Longenhagen: I’d guess end of year he’s in the mix once he’s held this stuff for a whole season and hopefully thrown strikes against hitters who actually have a shot against him.
12:04
lukesingy: How are you feeling about Dylan Crews? Still a top prospect who just needs time in the minors?
12:04
Eric A Longenhagen: I still think he’s so talented that he’s going to be good. Will he be franchise-altering? That outcome is leaving the building.
12:06
giantsprospects: Have you seen anything like what Luis Hernandez and Josuar Gonzalez having been doing to start the ACL season?

Eric A Longenhagen: Good morning from Tempe, where the temps are going to hit 100 and (it looks like) stay there for the foreseeable future. Brendan and I are working on the Orioles system writeup, I’m working on draft update. Enjoying another day in in the desert. Thanks for being here.  
12:04
GB: Lonbard get a grade bump?
12:05
Eric A Longenhagen: Not just yet, it’s gonna be fascinating and instructive to see him and Volpe side by side for the next little bit.

12:05
Erick: not sure what you can do about this, but christian scott’s stuff+ numbers from last night aren’t showing on his page / game log despite last night’s showing for other players. just thought i’d pass it along
12:05
Eric A Longenhagen: What I’m looking at has them visible:

Eric A Longenhagen: Morning, readers, welcome back. Let’s hop to.
12:04
Stashin: Who comes up first – De Vries or Emerson?  And who has a bigger impact this year and next?
12:06
Eric A Longenhagen: That’s a good one. Obviously, the Emerson extension makes him feel more proximate at the start of the discussion. JP Crawford has a .390 xwOBA right now and Cole Young has found his footing. So those two are holding serve at the moment. Emerson has been fine, he’s not kicking the door down…
12:08
Eric A Longenhagen: De Vries has now been at Double-A for a little over 200 plate appearances. He could justifiably be promoted soon. If he sustains this level of performance at Triple-A for another four-to-six weeks while Hernaiz continues to look like he has, there’s a more obvious vacuum there.
12:09
Eric A Longenhagen: I think De Vries will hit for power immediately. Emerson’s swing is less dangerous in ways and places that pitchers can access.
12:11
A dummy: As a prospect dummy, should I get excited over Pedro Ramirez or is it just a case of the cubs writers pumping up their guys?

Eric A Longenhagen: Good morning from the kitchen island in Tempe, I’m happy to be home and chatting from my usual spot for the first time in a month. The Nats list ran today, so go check that out. Brendan published Royals Wednesday, enjoy that, too.
12:02
NFP: Victor Figueroa real or no real?
12:02
Eric A Longenhagen: Watched a bunch of him this week while tying loose ends on Nats and his swing does look different.
12:03
Eric A Longenhagen: More viable, actually accessing the power. Let’s see if the spray changed…
12:04
Eric A Longenhagen: Looks pretty similar. Contact rate actually down compared to last year, but it’s early… Needs more info.
12:04
Pirates: Talk me off the ledge regarding Konnor Griffin. Is this still adjusting? Right now nothings working for him

Washington Nationals Top 41 Prospects

Below is an analysis of the prospects in the farm system of the Washington Nationals. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the sixth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Eric A Longenhagen: Howdy from Port Charlotte and sorry for the delay. I had planned on chatting from the Rays stadium during their Extended Spring game against the Orioles, but the Orioles (according to personnel on site) canceled. So I hustled over to a Halloween-themed coffee shop down the road.
12:16
Eric A Longenhagen: The Red Sox and Twins canceled three of their four extended ST games this week due to lack of pitching availability on both sides (Boston twice, Minnesota once) so I’ve seen a little less baseball on this leg of the trip than I had planned. I will try not to be machiavellian about how I respond, but I’m pretty frustrated with those orgs at the moment.
12:16
Tom: Eric, Justin Campbell keeps coming back strong in short outings. Is he back on the radar as a potential 4? Rule V eligible, so wonder how he fits for Guards future. Thanks!
12:17
Eric A Longenhagen: Saw him the day before camp broke and was at last night’s game with a scout who covers Cleveland and we both think Campbell is back from the dead. He was throwing harder for my source than he did for me on he last day of ST and has been sitting 93-96 so far, averaging 94.4 mph. That’s up from college. He pitched well in the spring outing I saw, four pitches, feel, built like a starter, moves like a starter.
12:17
Eric A Longenhagen: Let’s see if he can hold that velo all season as he goes from 0 to a whole slate.
12:18
Guest: How high are you feeling on Jonah Tong these days?

Eric A Longenhagen: What’s up party people? Happy Friday from my old man’s place in Catty, and thanks for being patient while I helped my grandmother with some stuff this morning. I’m gonna keep things to about 45 minutes today so I can catch my flight to Florida.
12:32
Oaktown Blues: Eric, thanks as always for your thorough work and unparalleled depth in the A’s prospect list. This is like Christmas morning for me!
12:32
Eric A Longenhagen: Hey thanks, it was fun to sit on them for a bunch of the spring and feel good about wrapping my arms around the whole lot of these fellas. Kade Morris!
12:33
Oaktown Blues: A 45 FV is a big jump in your eval of Junior Perez, considering he didn’t get a mention on their list last year. What changed for you? Just more confidence in the whole profile thanks to contact and defense gains?
12:34
Eric A Longenhagen: I was too light on his CF defense last cycle and that piece is the biggest reason why Perez > Bolte.
12:34
Dave T: Is MIL Luke Adams’ overly-passive hitting profile sustainable? His contact quality and approach are excellent, but he’s still not swinging the bat enough. And I’m worried about his defense.

Athletics Top 36 Prospects

Eric A Longenhagen: What’s up hosers? Good afternoon from Catasauqua, PA where I’m seeing family and baseball (mostly Nats affiliates) through next week.
12:02
Guest: Is it possible that Jefferson Rojas has gotten back on track?  True that he’s put on muscle?
12:05
Eric A Longenhagen: We didn’t think he ever got off track so much as he was a young player with an aggressive assignment last year. We had him as the top prospect in the system entering the year, 55th overall. He absolutely looks stronger, was selling out for power a little more than I liked when I saw him during the spring, though some of that was probably Breakout Game pressing.
12:05
Lord Thunder: With 17 walks in 15-plus innings including spring training, how long of a leash does Bubba Chandler have before he walks himself back to Triple-A?
12:08
Eric A Longenhagen: I wish Jared Jones were going to be ready to go sooner than mid-to-late May because there’d be a nice, natural swap there if Chandler is this wild until then. You’re seeing why we had McLean ranked first among pitchers and Chandler in the tier behind him. I’m not too worried about it, long term, athletes with this kind of arm speed tend to take a minute to reign it in. They could just let him struggle and learn on the fly and I think it’d be fine. Don’t burn an option year unless you really, really have to.
12:08
Jim: How fast should Jamie Arnold move through the minors?
