A’s Acquire DeJesus For Mazzaro, Marks

The A’s acquired David DeJesus from the Royals for right-hander Vin Mazzaro and left-hander Justin Marks, the teams announced today. Royals GM Dayton Moore says Mazzaro will join the team’s rotation and Marks will start the season at high Class A Wilmington. 

Mazzaro, 24, posted a 4.27 ERA in 122 1/3 innings for the A's this year with 5.8 K/9 and 3.7 BB/9. He became expendable when Oakland won the bidding for Japanese right-hander Hisashi Iwakuma earlier in the week. If the A's reach a deal with Iwakuma, he'll join Brett Anderson, Trevor Cahill, Gio Gonzalez and Dallas Braden in the team's rotation.

DeJesus batted .318/.384/.443 in 394 plate appearances this year, but he missed the final two months of the season because he required surgery on his right thumb. The 30-year-old, who has spent all of his eight-year career with the Royals, has experience in left, center and right. He joins Rajai Davis, Coco Crisp, Ryan Sweeney, Conor Jackson and Jack Cust in a crowded Oakland outfield that could clear up if Jackson and Cust are traded or non-tendered.

Marks, 22, posted a 4.87 ERA as a starter in the lower minors in 2010. The 2009 third rounder posted 9.5 K/9 and 3.4 BB/9 as he picked up his first significant experience as a pro.

DeJesus will earn $6MM in 2011 and qualify for free agency after the season. Mazzaro may qualify for arbitration as a Super Two next winter, but he cheap for now and won't hit free agency until after the 2015 campaign.

I think this is a win for the Royals but DeJesus is a good player and will fit in on the A’s.

5.9 K/9 and 3.7 BB/9 is pretty damn awful. I know Cahill has similar numbers and did well but that had more to do with his ridiculously unsustainable .230 BAA. The Royals clearly bought high here.

Not sure if you mean Batting Average Against or BABIP, but neither of those figures were .230 in 2010 for Cahill. If you meant BAA, that is absolutely sustainable. If you meant BABIP, it might not be sustainable, but BABIP is a stat that you should compare to an individual’s career number, not the league average. Who knows, he could be a guy whose career BABIP could stay in the .260-280 range (currently at .260 for his career).

Guest

Yes, I meant, BABIP, sorry. .238 really isn’t sustainable. Even a bump to .260-.280 means a significant increase in ERA. He’s a product of the defense behind him, the K/B ratio on any other team would mean a mid 4’s ERA at best.

But he isn’t on any other team, he is on the A’s. You are right, Cahill is not a great starter, but he is perfect for the A’s. Cahill hasn’t been lucky per say, he is just playing into the A’s strength, which is defense particularly infield defense. Billy Beane has concocted a rotation of pitchers that plays to their strength and in turn are efficient. Best of all they are cheap, and will continue to be cheap.

The A’s made a great trade here. They sold high on a starter who in reality, is not that good. David Dejesus can be a 4 win player for the A’s, while Mazzaro is most likely a league average starter.

Why can’t it be? He is a groundball pitcher with a nasty curve and sinker. He gets guys to beat the ball into the ground and there have been so many easy routine groundballs when he pitches that it’s just ridiculous. He probably wouldn’t be as good on any other team but if you watch him pitch, that BABIP won’t rise up that much and he is still improving. He isn’t a strikeout pitcher nor did anyone ever thought he would be. He is a groundball pitcher and a really good one at that.

Guest

Ground balls normally have a higher BABIP attached to them than fly balls do. The A’s have a great defense, but they’re not gods.

Guest

Even so just watch the guy pitch and stop looking at sabremetrics for a moment. The guy already had #2 stuff attached to him from the moment he signed that rookie deal with potential to be an ace. If you throw him behind a great defense he will become an elite pitcher. Throw him behind a team with garbage defense and he will become an average pitcher. Even if he does not repeat the season he had last season he is still going to be a very solid #2 pitcher because he will not regress so badly that he will become an average pitcher with an ERA in the mid 4s.

Believe whatever you want to believe. He had a fantastic season, no doubt about it. But you can keep the talk of ‘stuff’ and ‘believing what you see with your own eyes’. I’ll stick to the numbers, because numbers rarely lie. He will not repeat his 2.97 ERA. High 3’s, Low 4’s is where he will more than likely end up. Still solid, but not elite.

Guest

I agree he isn’t elite, and I’m pretty sure sportsfan isn’t claiming he is. But the Oakland infield is THAT good. They have top defensive players at every single position. They saved nearly 50 runs last year. That’s beyond great.

This is a great move!!!!!!!! I love this move for the Royals!!!!!!!!! I love Vin Mazzaro!!!!!!!

Subtract his back-to-back starts against the Yankees and Angels respectively, he had a great sophmore season. He is a future ace with swing and miss stuff, although it isn’t great stuff. He has one of the best fastballs for a guy his age and by record, most pitchers who have made 35 starts before their 24th birthday have turned out to be good pitchers.

I love this move for both teams but I love it for the Royals more. This is a steal while his value is low. He is one of the most underrated pitchers in Baseball.

This entire comment baffles me. Since when does Vin Mazzaro have “swing-and-miss stuff?” Let’s take a look-see:

K/9 rates at each level Mazzaro has been at in his professional career:
’06 (Low-A) – 6.11
’07 (Hi-A) – 6.74
’08 (AA) – 6.82
’08 (AAA) – 7.22
’09 (AAA) – 6.99
’09 (MLB) – 5.81
’10 (AAA) – 9.16
’10 (MLB) – 5.81

His best two numbers here came in sample sizes of fewer than fifty innings, so trying to justify “swing-and-miss stuff” with those numbers would be completely absurd. He just doesn’t miss many bats.

Good velocity, or even good overall stuff, does not guarantee strikeouts or success. Just ask Joe Saunders, who has been unable to get swings-and-misses despite above-average stuff from the left side.

Vin Mazzaro is not a future ace. His ceiling is a future #3 starter, and he’ll likely settle into the back-end of a rotation as a nice strike-thrower who doesn’t miss enough bats to be anything more.

You could also throw out his two best starts, 7/4 against Mighty Cleveland and 7/18 against Terrifying Kansas City, a combined 15 innings with 2 ER allowed, and you’d end up with a truly terrifying season. You can cherry-pick the two worst starts of nearly anybody in the majors and end up with an upper-half-of-the-rotation starter. An FIP of 5.13 and xFIP of 4.72 are indicative of his true skill level.

Like azdsnd pointed out, it’s pretty exaggerated hope to think he’ll be an ace.

Also I think your exclamation mark key was sticking or something, much like it was when you acted like you were the number one fan of the A’s the other day.

I love baseball too and I can sit down and enjoy a game between any two teams, but to claim that you’re this HUGE fan of every team is nauseating. There are teams I like more than others, but as a Blue Jays fan I find it annoying that when the Jays make a move you’re the number one Jays fan, then the Royals make a move and you’re the number one Royals fan and so on.

You also talk down to everyone on here as if no one else knows anything but you, which I think is pretty pathetic. You expect everyone to take everything you say as fact and not question it at all. I don’t go on here to read your silly trade ideas, you have ruined the discussion board for many people like myself.

You know a lot about baseball, I won’t argue that, but other people do too, including many who oppose what you say.

Guest

Actually, you’re wrong because I love discussing Baseball topics with everyone on here and the reason you see my posts so often is because when someone replies to my comment, it goes to my phone, then I will reply instead of ignore it.

I by no means think that I know more than anybody in fact I could name many people on here who know more than me. I’m myself, I love every team and if you don’t like that then I’m sorry, but the Jays and the Royals are two at the top. I do have confidence ibmy knowledge though therefore if someone tells me something that I disagree with I will say it, doesn’t mean I’m belittling anybody.

Maybe it’s just your writing skills that need work then, because every time I read your comments they go two ways: If you agree with someone it comes across as “Oh good job” as if you were some sort of teacher, rewarding their students. (Thus talking down to people) If you disagree you just start with “You’re wrong,” as you did just now. (Also talking down to people)

That’s my opinion and because you write on every single post as if we are all dying to hear from you, you’re going to have to be open to that type of criticism. I don’t mind that you constantly post on here, it’s more that you talk down to people.

I hear ya and am not taking it personally at all in fact I’m absorbing it. And thanks for the feedback. I do love MLBTR though and Baseball as I said before, which is why I comment whenever I’m at a computer, but I guess what you’re trying to say is its not so much the excessiveness as it is the way I come accross sometimes, which I’m going to work on because I don’t want to make people feel bad at all and I guess your trying to say that that’s what I’m doing sometimes.

But if I like to make people feel good by saying I agree or good stuff instead of giving a like because its more direct and again, makes people feel good. And next time instead of saying you’re wrong and more, ill just say why I disagree but its hard sometimes to get your point out when you feel defensiveless

Exactly, for me personally, I always learn more by having an open mind about the game because no one can or will ever know everything about the game. I’m glad you took the message because I don’t enjoy hating on people unless I feel very strongly.

Anyways, I still disagree that someone can be a hardcore fan of every team (and this is coming from someone who owns a hat and shirt for every team, symbolizing my passion for baseball) but if that’s how you enjoy the game I have no problem. I’m all about promoting the game.

Guest
Dave_Gershman

I agree with you and like your devotion and we are very similiar. I have every hat, almost there with the shirts, but I guess what I can tell you is, like you, I just love the game of Baseball, and since I follow every team, I just love every team I don’t know how else to say it. But some teams I like more than others.

And I really appreciate the help and feedback. This conversation is the type that I love having, just talking Baseball. any team, player, minors, Majors, College, HS, ballparks, fans, whatever. I just love talking Baseball. But back to what we were saying, your trying to tell me that I don’t know everything about the game? Come on! Joke — gotcha

Guest

Unless they non-tender Jackson and Cust, which is expected, then it makes perfect sense. Despite his ability to steal bases, Rajai Davis is a fourth outfielder.

Guest
4 years 7 months ago

Cust is a non-tender again. And the A’s likely won’t resign him this time.

Guest
Flharfh
4 years 7 months ago

Anyway Cust is pretty much a full time DH, he shouldn’t even factor into the A’s outfield discussion.

Guest

because they have no intentions on signing that guy out of Japan right?

Guest
myname_989
4 years 7 months ago

No, because they traded a controllable starter with good stuff for a year of a 32 year old outfielder returning from injury. It makes no sense because they didn’t need another contact-hitter type. They needed a power bat to drive in runs in the middle of their order. Any deal Mazzaro was involved in should have justifed those means.

Guest

You can spin a trade any way you want. You decided to point out the positives of Mazzaro and the negatives of DeJesus. DeJesus not just a 32 year old outfielder returning from injury. He has great plate discipline and above average fielding capabilities. Mazzaro has a mediocre ceiling and likely isn’t valuable enough to be swapped for a legitimate power hitter. He also has no place in the A’s rotation.

Guest
Sam_Lee

I don’t disagree with you, but A’s fans were turning their nose up at the idea of a lot of players because Mazzaro was so valuable. Like I said, not disagreeing.

Guest
Donskoy
4 years 7 months ago

For one, DeJesus is 30 years old, not 32 and if my memory is alright, Crawford is 29 and is expected to give 5+ years. Also, Mazzaro, probably the worst of the A’s starters, was expendable because of the A’s oppurtunity to sign the Japanese guy, who’s name escapes me, thus giving the A’s less leverage and making him (Mazzaro) less valuable.

Guest
sportsfan07

Mazzaro easily has the worst stuff of all of the starters. His stuff has the least amount of movement and really the only thing he has going for him is that he has above average control more times than not. His control is above average at best but it’s the movement that just kills you because his stuff is just so straight. His fastball is straighter than ruler.

Guest
mrsjohnmiltonrocks

Well, consider that Mazzaro is replacing Bannister. That’s an upgrade on both performance and dollars spent.

I don’t hate this deal; both sides got rid of something they didn’t really need for something that is probably better than what they already had. Win/Win I guess.

Guest
sportsfan07

This is actually a pretty bad trade for the A’s if they don’t do something about that OF log jam.

Guest

Coco Crisp had a 3.3 WAR while the remaining 12 outfielders they used COMBINED for 0.1 WAR while DeJesus managed to post a 2.9 WAR despite ending the year early due to injury. The A’s had 5 young starters plus Josh Outman, Bobby Cramer and the rights to Hisashi Iwakuma, now they have 4 young starters plus each of those guys. They were dealing from a point of depth by letting go of Mazzaro, it was hardly unexpected to see him dealt.

cant decide if this is a good trade or not. i feel like the A’s could have got more out of thier extra pitching

Guest

That’s my first thought, too. DeJesus is decent, I guess, but I’ve been waiting his whole career for him to come into his own and it hasn’t happened.

Guest
friscofan101
4 years 7 months ago

i think the A’s should have waited for some of the top pitchers to get picked up so some of the teams who missed out might be willing to overpay for one of their extra pitchers.

Guest
4 years 7 months ago

I’m with you – I just don’t get the Dejesus “hype” every year. He’s okay. A good guy to have, but not really a huge talent or exceedingly good at any aspect of his game. A well-rounded above average.

Guest

Even though it was only one game it must suck for Justin Marks to know he pitched to an ERA of infinity last year.
