Top 25 Seattle Mariners Prospects for 2009

by Jon ~ December 30th, 2008 at 11:06 pm

Offseason 2008/2009

Here are my top 25+ Seattle Mariners prospects as of today.  I will try to post updated lists several times a year: offseason, early season, post- draft and International Signing Day, and perhaps a few in between.

I received some good input from Rob T. on this as well, and he’ll be co-authoring the lists in the future.

Please try not to get too worked up about exact placement of the players on the bottom half of the list (including the “Notables”).  They’re fairly interchangeable, depending on what you think makes a good prospect.  I appreciate all feedback, and feel free to submit your sleepers!

If you want to skip the blurbs there is a chart at the bottom of the post.

1.) Carlos Triunfel, MIF – Finally showed a little bit of pop in 2008 and finished the year with a very good AFL performance against much more advanced competition.  2009 could be a big year for him.

2.) Phillippe Aumont, RHP – Amazing stuff and control for someone whose mechanics are such a mess.  If he can smooth out his follow-through and start repeating his delivery he’ll become one of the top pitching prospects in baseball.

3.) Michael Saunders, OF – He’s not typically regarded as a high upside prospect (although Baseball America called him a “potential five-tool talent” before the season), but a safe bet to be a Major League contributor.  Line drive swing (although a bit long), plus speed, good defender.  If he can stick in center field his value will increase, but right now he looks like a left handed version of Jayson Werth or Corey Hart.

4.) Greg Halman, CF - The tools are there– more so than anyone on this list– but for now I’m unconvinced that he can get around the awful K:BB ratios that are handicapping him.  He’s performed at every level through AA; will it continue?

5.) Juan Ramirez, RHSP - Doesn’t have the numbers of Aumont or Pineda, but of the three he’s known as the most polished.  His fastball runs low-to-mid 90s and he throws a sharp breaking curve and solid changeup as well.  His body and delivery have been compared to Rafael Soriano.

6.) Adam Moore, C - I want to have him higher, but this is where he lands right now.  .900+ OPS for each of the last two seasons and a reputation for handling pitching staffs well, Moore could be the complete package behind the plate after a little more defensive fine tuning.

7.) Michael Pineda, RHSP – A lot of people have him higher on their lists after a breakout campaign in 2008, but I want to hear more reports about how his secondary pitches are developing.  I am in love with his control, though (128:35 K:BB).

8.) Matt Tuiasosopo, 3B – Some people view him as a disappointment, but a strong second half in 2008 and a good approach at the plate have made me a believer.  I think he’ll have a big year in 2009, though he has to work on his defense.

9.) Mike Carp, 1B – His bat isn’t as powerful as you’d like from a first baseman, but a solid 2008 at AA (.299/.403/.471) and 17 game VWL stint (.260/.403/.480) have me believing he can be a useful major leaguer.   Is among the most disciplined hitters in the system.

10.) Dennis Raben, OF/1B – Only 27 pro games to go from, but he’s expected to shoot through the system and could move up this list as his minor league sample grows.  Profiles similarly to Carp, but he should have more power, which bodes well.  He’ll leapfrog Carp on this list sooner than later, but he needs to add to his professional resume first.

11.) Jharmidy DeJesus, 3B – Showed good skills as a 18 year old in his USA debut this past season.  Tons a raw power and seems to take enough walks to get by.  Defense at third appears to be a major problem, however.  He was a personal favorite of mine in 2008.

12.) Rob Johnson, C – Looks like a very solid backup with starting upside perhaps in the vicinity of Dan Wilson.  Could be higher on this list, and may be dealt this offseason.

13.) Mario Martinez, 3B – Already looking like a good hitter and most think he’ll develop some decent power as well.  Struggling defensively at third base since moving over from shortstop, but he’s still very green.  He could move very quickly up or down depending on how he does in A-ball.

14.) Maikel Cleto, RHSP – He’s very young and throws the heat, which is good enough for him to crack any prospect list.  Similar problems to most young fireballers: control, secondary pitches, repeating deliver.  He’s a starter now, but many think he’ll end up a closer in the big leagues.

15.) Nathan Adcock, RHSP – Largely overshadowed by the big-three in Wisconsin (Aumont, Ramirez, Pineda), this guy is looking like a very good pitcher.  He improved his walk and strikeout rates this past season and looks like a solid middle-to-back of the rotation starter at this point.

16.) Shawn Kelley, RHRP – Very good reliever.  Low-to-mid 90s fastball and great slider to go with very good control.  Injuries could be a concern.

17.) Gabriel Noriega, SS – He’s a great defender and a switch hitter with a bit of power potential, which is enough to make him a very good shortstop prospect.  This kid may be Seattle’s real shortstop of the future, though he spent 2008 in rookie ball.

18.) Efrain Nunez, OF – A 17 year old that has yet to debut in the United States, this kid was a highly regarded international prospect like many others on this list, including Triunfel, DeJesus, Noriega and Morban.  Switch hitter, some good plate skills and plus raw power.

19.) Gaby Hernandez, RHSP – A very highly regarded pitching prospect as recently as last offseason, he seems to have lost the bite on his once great curveball as well as a few MPH on his fastball.  2009 could be considered a make or break season, although he is still just 22.  Last year he would have cracked the top 10.

20.) Mike Wilson, COF – Getting old for a prospect that hasn’t yet reached AAA, but Wilson is still extremely powerful.  He posted a .937 OPS with AA last season, and could make his MLB debut at some point in 2009 now that he’s been re-added to the 40-man roster.

21.) Justin Thomas, LHRP – I might have him higher if he remained a starter, but he seems destined for a relief role and could make Seattle’s Opening Day roster for 2009.  Solid fastball/slider/change combo, but how much value can you truly get out of a lefty reliever?

22.) Julio Morban, CF – Because he’s only 16 and may not make his USA debut until 2010 or later, I can’t put him any higher on the list just yet.  He is expected to be a very good player, with scouts and insiders calling him the “best pure hitter” to sign this year out of the international prospects pool, adding that he has a “strong grasp of the game.” 5’11″ 178 lbs, solid approach from the left side of the plate and good bat speed.

23.) Ezequiel Carrera, CF -  A plus-plus defender in center, a patient hitter at the plate and a speedster on the basepaths.   Some believe he could develop some power down the road as well.

24.) Brett Lorin, RHSP – A huge guy at 6’7″ 245 lbs, he was a 5th rounder this year out of Long Beach State and struck out 61 hitters in 52.1 innings in his first professional season, including 13 hitters in Everett’s home opener.  Could rise up this list quickly.

25.) Tyson Gillies, CF – Saw him play once in Everett.  Looks like a good athlete and is very fast.  Good defender at any outfield position with a grade-A arm, and works the count well from the left side of the plate.  Hasn’t hit the ball for much authority just yet, but could be a leadoff option if he reaches his potential.  It’ll be interesting to see if he can overcome his hearing disability.

Other Notables:

LHRP Cesar Jimenez, 1B/LF Johan Limonta, RHP Doug Fister, 1B/LF Javier Brito, MIF Reegie Corona, RHSP Fabian Williamson, LHSP Henry Perez, OF/DH Carlos Peguero, OF Denny Almonte, RHRP Stephen Kahn, OF Kuo Hio Lo, LHRP Jose Lugo, RHSP Kenn Kasparek, LHSP Nick Hill

Sleepers:

Steven Hensley (3rd round) and Aaron Pribanic (5th),  RHSPs - These high 2008 draft picks haven’t seen much pro action yet, but could climb the ladder quickly if they perform in 2009.

Luke Burnett, RHP - Another 2008 draft pick that has barely tasted pro ball, this guy was once a highly regarded starter whose stock plummeted after an injury, allowing Seattle to steal him in the 14th round.  He may not be durable enough to remain a starter, but some have suspected that the 6’8 260 pounder could rocket through the system in a season or two if made into a full-time reliever.

Donnie Hume, LHSP – A confident lefty that pitched for collegiate baseball hotbeds Long Beach State and San Diego State before becoming an 8th round pick in 2007. He relies on control, but showed the ability to miss bats as well in his pro debut.

    Quick question – Can you elaborate how Mario Martinez has struggled defensively at third? I haven’t seen any defensive metrics for minor leaugers, so i’m kinda interesed. Is this just him transitioning to a new position? I just ask b/c BA’s scouting report on him says he has plus range and a plus arm, so i’m assuming the tools quite haven’t caught up the performance yet.

  2. Jon Shields

    Unfortunately there are no such minor league defensive metrics, so I’m going off of what I’ve read about Martinez. (I’m curious, was that scouting report from before or after the position change?) I believe the struggles are just a matter of adjusting to the new position.

    Many top prospects start out their pro careers as shortstops, but as their bodies mature they grow out of the position. Several of the names on this list are examples of this, including Matt Tuiasosopo, Jharmidy DeJesus and Mario Martinez.

    I’ve only been able to watch Tui and DeJesus myself, but all three are said to be struggling defensively and it would be safe to say that it’s the transition they’re struggling with. All three are tremendous athletes and none of them seem to lack the physical ability to be a great defensive third baseman. It’s just a new experience for them, and it will take time.

    This isn’t the same as taking Jeff Clement and sticking him in center field. There is nothing Jeff can do to become a good defensive CFer, because he just isn’t athletic enough and doesn’t have the body type. For these three 3B, there is nothing physical getting in their way.

    Just like these prospects have to learn to hit like major leaguers, they also have to learn to field like major leaguers. Few guys in rookie ball are going to pick it like Beltre.. just like hitting the ball the other way, defense is a learned skill.

    Errors aren’t typically a great stat to use, but they’re all we’ve got in this case. Martinez made 16 errors at 3B in just 62 games… not good. Just sounds like he’s adjusting to all the new plays he has to make as a 3B that he didn’t have to make as a SS, and I wouldn’t worry about it. Kid looks like a great athlete in the photos I’ve seen.

    Hope that helps. Welcome to the site.

    Your list looks good. I am most excited about Raben. I have read a ton about him, and if he can stay healthy I believe he will be a great source of power. Before last season, there were some who gave him an 80 on the scouting scale for power.

    I also really like Almonte. I know he hasn’t shown much, but I think he can. We will learn a lot about him this year.

    One of the guys that I think will surprise people this year is Mike Wilson because things finally seemed to click for him from a hitting standpoint, particularly his 117/62 K/BB ratio which is not too bad for a guy with his power. I think he make Vlady expendable because they have similar skill sets, so we might be able to use Vlady as trade bait.

    It also looks like the High Desert Mavericks will have a starting rotation of Aumont, Ramirez, Pineda, Adcock and Cleto unless Cleto is moved to the bullpen, but either way it’s an exciting group of young pitching prospects.

    RE: Raben – I think he could be a really good power source as well. The first time I saw him in person I couldn’t believe how strong he looked. Some of that could have been from being surrounded by Aquasox teenagers, but the guy looks like a beast. Pair that with an advanced approach at the plate and good things may happen. An 80 seems a bit extreme at this point, but we’ll see what he does in 2009. Just imagine what his numbers might look like if he gets significant time in High Desert!

    RE: Almonte – I originally had him around 22 on the list, but he needs to prove himself in 2009. I’m not saying he needs a breakout season, because that would be ridiculous at age 20. He just needs to continue working on his swing mechanics and possibly cut down on the strikeouts. He has plate discipline, so it’s not as if he’s swinging at a lot of bad pitches. He just makes poor contact.

    If he shows some improvement he could start jumping up the list, because the tools are there and he could be an exciting player one day, but 186 Ks in just 492 PAs is a terrifying tally. Some think that he should drop the switch-hitter tag and only hit from the right side. He’s hitting more home runs from the left side, but more consistent line drives as a righty.

    RE Wilson: Giving up switch hitting seems to have helped him find some consistency. Hopefully he can perform in Tacoma.

    RE HD Rotation: That rotation would be possibly the best in minor league baseball, representing all five of our top pitching prospects. Unfortunately, I don’t think they’ll all start in High Desert right away, but we’ll see.

    RE: Raben- I wonder how we’ll use him as an OF or as a 1B heard somewhere he is a legit 40 HR threat and he has great plate discipline and walks a lot.

    I been reading this blog for about a month now and I am really enjoying it. Thanks for all your hard work. What would you say the ETA on Triunfel and Aumont are? I was thinking Opening Day 2011, maybe at the earliest Sept. of 2010. What do you think?

  8. Jon Shields
    Jon Shields

    Thanks KK. Your guess is as good as any. If Triunfel continues to rise through the system methodically, September 2010/Opening Day 2011 is right about when we should see him for the first time, although they are in no hurry to get him into the big leagues. They’re not going to want to start his arbitration clock until they absolutely have to.

    Aumont could appear around the same time, but he’s a completely different case than Triunfel. Aumont already has amazing stuff, he just needs to work on building up his arm strength and getting his messy mechanics in sync, and who knows how long that will take. I think I’ll be able to guess a bit better once I see him throw in Spring Training, but 2010/2011 is a pretty safe bet.

    What is the deal with Victor Diaz, is he even under team control anymore? Why would the Mariners not want him anymore he had really good stats last year at Tacoma. I know is pretty old to be a real good prospect and he strikes out a lot, but how can you totally ignore those stats.

    He won the MVP in his winter league this year with 50 RBI’s and 17 HR’s in only 195 AB’s.

    Jon, what is the deal with him?

  10. Jon Shields

    Victor Diaz was a minor league free agent this offseason. I’m not sure if he has latched on anywhere yet.

    The guy can hit, and it’s a shame that he hasn’t gotten a real chance in the last couple of years. His MLB statlines don’t look pretty at first glance, but they prove that he can hold his own in the bigs. In my mind he should have been Seattle’s DH in the second half last season.

    Alright thanks.
    The M’s shouldn’t have let him go.
