The Royals have acquired right-hander Lucas Erceg from the Athletics, per announcements from both clubs. The A’s receive right-handers Mason Barnett and Will Klein as well as outfielder Jared Dickey.
Erceg took an unusual path to being a midseason trade target. He was drafted by the Brewers as a third baseman back in 2016 but flamed out as a hitter and eventually moved to the mound. In 2021, he tossed 47 2/3 innings at the Double-A level, allowing 5.29 earned runs per nine. As you might expect for a new convert to pitching, control was an issue at first. Erceg gave out walks to 16.4% of batters faced that year but he also got strikeouts at a decent 21.1% clip and grounders at a strong 56.8% rate.
He has generally made positive progress in each season since as he has become more accustomed to his new career path. In 2022, he logged 61 1/3 innings between Double-A and Triple-A with a 4.55 ERA, a decent step forward from the prior season. His strikeout and walk rates also improved to 24.4% and 13.1%, respectively.
In 2023, he started the year back at Triple-A before he was traded from Milwaukee to Oakland in a cash deal, with the A’s adding him to their roster shortly thereafter. He tossed his first 55 major league innings last year with a 4.75 ERA, 27.1% strikeout rate, 14.3% walk rate and 46.1% ground ball rate. The control was still an issue but it was an encouraging debut nonetheless, especially for a guy with such a limited track record on the mound. He averaged 98 miles per hour with both his four-seam fastball and his sinker while also throwing a changeup, slider and cutter.
His second major league season has seen him continue to grow. His 26.3% strikeout rate is a slight drop from last year but he has cut his walk rate all the way down to 8.3%, with his ground ball rate also creeping up to 50.5%. That’s resulted in a 3.68 ERA in 36 2/3 innings, with Erceg racking up three saves and 12 holds on the year.
The A’s didn’t necessarily have to trade Erceg now. He came into this season with less than a year of service time, meaning he can still be retained for five seasons after the current campaign, but there are also logical reasons why they were tempted to make him available.
Due to his unusual trajectory, Erceg is now 29 years old. With the A’s deep in a rebuild, he will be in his early 30s and into his arbitration seasons by the time they are likely to be competitive again. Relievers are generally considered pretty volatile in general and that might be even more true with Erceg, who has such limited experience relative to most of his peers. Rather than hold him and take the risk that his performance takes a downturn or he suffers an injury, the A’s decided to make him available at this deadline, while the industry consensus has generally been that the acquisition costs for pitching have been quite high.
The Royals have surged back into contention after many years of struggles and have been aggressive in bolstering their roster for a playoff push. The bullpen has naturally been a target area for the club this year, as their relievers have a collective 4.30 ERA that places them 24th in the majors. Their 18.6% strikeout rate is actually second to last, ahead of only the Rockies.
They acquired Hunter Harvey from the Nationals recently and this trade for Erceg will give them a couple of fresh arms who both have big punchout potential. They also added Michael Lorenzen as a swingman to bolster the group in general, as he can help them in multiple ways.
Considering the A’s just got Erceg in a cash deal last May, they are likely quite happy to cash him in for three younger players barely over a year later. Barnett, 23, was a third-round pick of the Royals in 2022. He made 23 starts last year between High-A and Double-A with a 3.30 ERA, 28.8% strikeout rate and 10.5% walk rate. His ERA has jumped to 4.91 at Double-A this year but with similar peripherals. His .336 batting average on balls in play and 64.2% strand rate are probably masking those underlying metrics, as he has a 27.4% strikeout rate and 9% walk rate. Baseball America currently lists him as the #11 prospect in the Royals’ system while FanGraphs has him slightly higher at #7.
Klein, 24, is a reliever who made his major league debut this year. He has 5 2/3 innings in the show so far with a 6.35 ERA. Command appears to be the biggest issue with him. Since being selected in the fifth-round of the 2020 draft, he has tossed 216 minor league innings with a 5.17 ERA. His 30.7% strikeout rate is quite impressive but he’s also given free passes to 16.1% of batters that have come to the plate. BA and FG both put him at #16 in the system.
Dickey, 22, was just drafted in the 11th round last year. He’s slashing .269/.360/.424 in High-A this year for a wRC+ of 127 and has also stolen eight bases. Neither BA nor FG have him on their KC prospect lists.
Jeff Passan of ESPN first reported on X that Erceg was headed to the Royals. Mark Feinsand of MLB.com reported the return on X.
CubsWin108
this is the best trade deadline ever
kylegocougs
Agreed, it’s been hot fire
LordD99
Someone on MLBLN said so many teams still being in the hunt is why this is a slow deadline because there are more buyers than sellers. Whiskey. Tango. Foxtrot. This has not been a slow trade deadline. One of the most active I can remember.
holecamels35
I feel like it’s a lot of moves but no big ones that really make a difference. As a pirates fan I am also very upset with the lack of activity.
Logjammer D"Baggagecling
I hope this is a sign of an insane off season.
sad tormented neglected mariners fan
Sadly this next offseason is gonna be like the last one
I’m ready for the 2025-2026 one though
User 1939973770
Wow that is not expected
Simm
Good arm for the royals.
This may have cost a lot.
RoyalsFanAmongWolves
I hope it won’t cost Carter Jensen or Gavin Cross because those are two guys I’m looking forward to making their MLB debut in probably 2026. we can’t afford to trade Gavin Cross because we are a little thin on outfielder prospects.
Billg7987
If it didn’t, the Orioles front office will have some questions to answer. This guy is good.
Unwritten Rule Breaker
Looks like they gave up a couple guys who have a ceiling of middle reliever and a lottery ticket outfielder.
Roob3ucla
Is he going to take over the closer role or 7th/8th inning guy?
LordD99
Yes.
oaklandfan22
Oh gosh…
Poke56
Knowing JJ…after yesterday’s trade be probably gave up Witt in this trade
lesterdnightfly
Evidently you aren’t “knowing JJ” very well.
Poke56
Jaj gave up a top 5 prospect having a good yr in AAA tor a # 6 starter at best. Why deal from an area that a major weakness for s scrub insted of promoting the prospect. I’m sorry but dude who is 32 and gonna walk at the end of the year isn’t worth giving up a top 5 organization prospects
Rexhudler86
@poke56 you must not know erceg is a reliever that was a two way player that just went back to pitching in 2021, and has 5 years of control that’s still a cheap reliever with upside that is continuing to get better.
Poke56
I’m talking about what he gave up yesterday. If he WAY over paid for lorenzen 9m sure he will way over pay again to this trade. I have NO problem with the trade for Eeceg. I’m just afraid based on JJ history what he had to give up.
max l
Lucas Erceg has 5 more years of control left! He’s old because he was a 2 way player and just recently went back to pitching. And you can NEVER have too much pitching especially in the bullpen. The Royals won back-to-back AL pennants in 2014-15 by adding bullpen arm after bullpen arm and shortening the game
Rexhudler86
@poke you might not like the deal if your talking about the loki trade for a 26yr pitcher in triple a. Erceg is probably one of the top options available, and if you follow the royals you know that prospects don’t always work out.
TLB2001
In what world is Walter Pennington a top 5 prospect?
Rexhudler86
@tlb he’s another two way guy that’s figuring it out, but that wasn’t too expensive for lorenzen. Erceg is going to be pricy especially if the orioles were outbidded.
Billy Idol
Crawl back under rock
kcmark
JJ’s history. Last year he fleeced Texas for Cole Ragans.
bobellis75
Are you talking about the Lorenzen deal? They gave up a 26 yr old LH reliever…and the ML roster has plenty of LH pitching. Oh no…we gave up a 26 yr old “prospect”………not sure I’d consider him a top 5 prospect, as a KC fan…and if he was a top 5 in this system (according to some sources) it doesn’t mean he’d be a top 5 elsewhere. You act like we gave up a top 100 prospect for a rental. We did not.
julyn82001
I like Lucas but it seems A’s are just getting younger, talented and inexpensive…
timfoolery
Do you know how broke our owner is?
Saint Nick
Honestly never heard of this guy until yesterday.
Simm
He has a big arm. He is pretty good had an injury earlier in the year but seems to be okay now/
lesterdnightfly
Lost since 2022 in a cave in the Flint Hills, eh?
Saint Nick
Worked for fedex. Plane crashed and I was stranded on an island for 4 years.
shark stitches
Glad you made it back!
Datashark
29 is too old to be on the A’s
they usually have under 26 or over 35 (token vet)
Rexhudler86
He was a two way player, that just became a pitcher. He still has 5 years of control.
Murray Rothbard
Cost of pitching has been high this deadline. I’m interesred in what the A’s bring back for L:ucas
Datashark
he is a reliever likely at best someone at the bottom of the top 30 prospect or not on the 30 list. if they get better than that – its huge trade for A’s
oaklandfan22
Don’t think you saw what Trevor Rogers just fetched
Datashark
Rogers is a STARTER they usually fetch more than mid-relievers
Datashark
Alright they got WAY more than I expected. Two top 20 prospects from KC
For Love of the Game
Way more in quantity, not quality.
RoyalsFanAmongWolves
please take good care of Will Klein
jbigz12
Probably something decent in return.
Murray Rothbard
I was expecting something more similar to what the Yankees gave up for Mark Leiter jr. Erceg has more years of control and is younger too.
This one belongs to the Reds
They might be a small market, but KC really had a plan and going for it.
RonDarlingShouldntBeInTheHallOfFame
Love seeing the Royals going for it. They’ve built a damn good squad, for pennies on the dollar, and it’s excellent for Baseball.

Also just traded for DeJong, so as a Sox fan I’m happy. No return known, yet I’m happy. How sad is that?
letsgooakland123
Great story, great player! Happy for him
Perksy
Erceg should close for them. McArthur Stinks
futuregm12
Why are they giving up so much for nobodies?
RonDarlingShouldntBeInTheHallOfFame
It’s the market right now. They’re forcing their window open to maximize opportunity. Personally, I have a feeling they’ll go after a star to pair with Witt in the offseason.
Datashark
Wow that is a great haul for the A’s.
ranked prospects #4, #18, and a dickey
bobsugar84
I wonder if he closes. McArthur just went one two three after a couple of awful outings. He was pretty solid before then though so time will tell. My guess is if he blows one more over his next five he is out.
On a side note, Harvey who they got last week, hasn’t been great for them either and he left with back spasms two days ago. So if he goes on IL Erceg would take his place as 8th inning guy for now.
Dash 2
Not sure I like this for the Royals.
Erceg is a decent bullpen arm, but wouldn’t be surprised if Klein develops into a dominant closer.
YourDreamGM
A for KC. Absolute bargain in this market. Gave up a real nice back end reliever with some control issues. A mid to back starter prospect. Well worth it.
C Oakland. Not impressive in this market but fair enough. They can develop themselves into a better return.
User 3997712419
Ok, nice get JJ. Controllable until 2029? That’s nice value!
