Who are the best, realistic relief fits for KC Royals at MLB trade deadline?

The MLB trade deadline is getting perilously close, and baseball fans everywhere are waiting for what their team will do. The KC Royals already have a handful of trades this month, most notably acquiring right-handed reliever Hunter Harvey from the Washington Nationals.

The initial sticker shock did not please Royals fans, but the bullpen trades around the league since have mad losing Cayden Wallace and the 39th overall draft pick more palatable.

Harvey's performance with the Royals has been inconsistent, and there are also shortcomings in the remaining relief options. Kansas City must actively seek another relief pitcher before the July 30 deadline.

We can throw names around until the cows come home. Just like any acquisition pool, there are levels to this. Let's look at 12 pitchers across four different levels and what makes each an enticing trade target.

Top, but improbable, trade targets

These are the players who will capture the headlines, with every fan base clamoring for them. However, the Royals do not have enough valuable prospects to acquire any of these relievers.

1. LHP Tanner Scott, Miami Marlins

Stats: 6-5, 44 G, 18 SV, 1.18 ERA, 3.23 FIP, 10.45 K/9, 5.32 BB/9

Tanner Scott is perhaps the most valuable player who can be leased at this trade deadline. As a formidable left-handed reliever, he has accumulated 50 saves since joining the Marlins in 2022. His dominant pitch combination consists solely of a fastball-slider mix.

According to The Athletic's Ken Rosenthal ($), the Kansas City team has expressed interest in Scott, but the asking price is likely too high for them. With numerous contending teams pursuing him, the Marlins are poised to secure the best possible value in any deal.

2. RHP Kyle Finnegan, Washington Nationals

Stats: 2-4, 45 G, 28 SV, 2.47 ERA, 4.18 FIP, 9.07 K/9, 2.89 BB/9

Finnegan's effectiveness lies in his ability to control the game, especially in high-pressure situations. His ground-ball rate of 42.7% and improved command, with a 4.6% walk rate since June, illustrate his strong performance. The Nationals exclusively use him as a high-leverage arm, and his 24 shutdown performances demonstrate why they have so much faith in Finnegan.

Finnegan, like Harvey, is not available for rent, which is important to Kansas City. He is attracting interest for this reason, and his strong track record goes back to 2022. Several NL teams, including the Philadelphia Phillies and the Los Angeles Dodgers, are also interested in the right-handed pitcher. Even though Kansas City has acquired Harvey, it doesn't mean they can't make another deal with the same team. However, it seems unlikely, especially because Finnegan's price tag is too high.

3. RHP Michael Kopech, Chicago White Sox

Stats: 2-8, 43 G, 9 SV, 4.74 ERA, 4.82 FIP, 12.16 K/9, 4.95 BB/9

With the White Sox reportedly less likely to trade stars like center fielder Luis Robert Jr. or starter Garrett Crochet, that means they will squeeze all the value they can out of their remaining trade chips. Kopech is no different, despite his ugly numbers.

The righty racks up strikeouts at a breakneck pace, thanks to a fastball that averages 98.5 MPH. The abysmal White Sox fielding has hampered his game-level results, but Kopech is still learning the bullpen ropes. The reason I have him out of Kansas City's reach is simply because they are in the AL Central.

“The White Sox are telling contenders in the AL Central, including the Minnesota Twins, that they really would prefer not to trade within the division,” USA Today's Bob Nightengale wrote on Sunday.

Targets that are in a higher tax bracket

These stars are undoubtedly in demand as the trade deadline draws near. The acquisition price will be high, possibly even higher than what the Rays received for Jason Adam. A large trade package will be required by any team hoping to acquire one of these three players. They will cost a lot to acquire—possibly even more than the Rays paid for Jason Adam. Before making a deal, the Royals must carefully consider their choices because adding any of these players could eliminate them from contention for a big bat come the trade deadline.

4. RHP Pete Fairbanks, Tampa Bay Rays

Stats: 2-3, 37 G, 19 SV, 3.19 ERA, 3.31 FIP, 8.35 K/9, 3.93 BB/9

Dealing with the Tampa Bay Rays in a trade feels like making a deal with the devil in baseball terms. While the Rays might not be dominating Major League Baseball this year, they have a strong track record of winning trades. This, combined with the high demand for late-inning relief pitchers, makes trading with Fairbanks a risky decision.

Fairbanks has achieved two consecutive seasons with an fWAR of 1.0 or higher, which is impressive for a reliever. Although he doesn't strike out as many batters, his career strikeout rate stands at 12.06 per 9 innings. At 30 years old and under contract with the team until 2026, Fairbanks offers both strong on-field performance and cost efficiency, making him a valuable asset for the Tampa Bay Rays. He would likely serve as the primary closer for most teams, which is a position that Kansas City desperately needs to fill immediately.

5. RHP Lucas Erceg, Oakland Athletics

Stats: 2-3, 38 G, 3 SV, 3.68 ERA, 3.45 FIP, 10.06 K/9, 3.19 BB/9

For the teams that want Mason Miller, they will have to settle for Lucas Erceg. The righty has the best raw arsenal available at the trade deadline, and the former position player still has room to grow on the mound.

The 29-year-old isn't a free agent until 2030 and only has 88 games in his MLB career. However, his dominant fastball and wipeout slider are impossible to ignore and likely make him one of the best setup men in all of baseball. I find it hard to believe Oakland values Erceg to a level similar to Miller, especially considering Erceg's age. I predict he will be on the move before Tuesday.

6. RHP Chad Green, Toronto Blue Jays

Stats: 3-2, 30 G, 7 SV, 1.74 ERA, 4.47 FIP, 7.84 K/9, 2.61 BB/9

The Blue Jays need to bolster their bullpen for the rest of the season, but they have already traded multiple bullpen arms. Would it be wise to also part ways with the valuable Chad Green?

Green's performance in the 2024 season has been impressive. He has maintained a 1.74 ERA over 31 innings. His effectiveness is evident from his solid 23.1% strikeout rate and respectable 7.7% walk rate. However, some advanced metrics, such as his 3.82 SIERA, suggest that his success may be influenced by luck, as indicated by a 100% strand rate and a low BABIP. Nevertheless, Green's skills make him a valuable asset in the bullpen.

Fangraphs' Dan Szymborski stated, "Green is unlikely to require a large price despite his solid ERA," and the need for middle infield help makes Toronto and Kansas City feasible fits.

Targets within reason and under team control

These targets are situated in the B-tier for trade deadline, making them perfect candidates for Kansas City. These teams are motivated to sell, and these options are not the top available arms in their respective bullpens. If the Royals are unable to acquire any of the players mentioned earlier, these three would make a great consolation prize.

7. RHP Austin Adams, Oakland Athletics

Stats: 0-2, 50 G, 0 SV, 4.21 ERA, 4.50 FIP, 11.39 K/9, 5.45 BB/9

The second Oakland Athletics player on the list, Austin Adams, isn't going to be the instant fix any team needs but rather a strikeout-heavy righty trotting from the 'pen. The Royals can use that, and Adams' value is ripe for a trade.

He won't be a free agent until 2026, but he's already playing for his third team in as many years. Adams is renowned for his powerful slider and fastball combination, and his ability to strike out batters has always been impressive. However, he has consistently struggled with command, as indicated by the high number of batters hit by his pitches throughout his career.

Adams, at 33 years old, has minimal trade value, and it's clear that Oakland won't make any significant progress with him on the roster. Kansas City should consider offering a lower-level prospect, as this could result in them acquiring a high-risk, high-reward reliever before the postseason push.

8. RHP Huascar Brazoban, Miami Marlins

Stats: 1-2, 20 G, 0 SV, 2.93 ERA, 2.62 FIP, 9.98 K/9, 3.23 BB/9

A late bloomer and success story from the Atlantic League, Huascar Brazoban could be a cheaper Marlins reliever Kansas City acquires.

Brazoban's 2024 season started off rocky due to visa issues that prevented him from participating in spring training and delayed his regular-season debut. Despite these setbacks, Brazoban's strong arm and effective pitch mix, including a cutter and sinker, continue to make him a key player for the Marlins when available.

The 34-year-old should be considered as a prime candidate for closing if Scott is traded, as per the Miami Herald. However, Miami should seize the opportunity to trade him away this week and capitalize on his success.

9. RHP Derek Law, Washington Nationals

Stats: 6-2, 51 G, 1 SV, 3.19 ERA, 3.53 FIP, 7.84 K/9, 2.47 BB/9

It seems that if Kyle Finnegan is proving too much for Kansas City, it might be time to consider Derek Law further down the pecking order. This right-handed pitcher is a dependable reliever for the Nationals, and would certainly be an immediate upgrade over pitchers like Sam Long or Christ Stratton.

Law has moved around the league but is far from a terrible reliever. While he may not strike out a lot of batters, his diverse pitching arsenal and clear command make him a safe choice for the bullpen.

Moreover, he is under team control through the 2025 season via arbitration, which could make him an attractive trade candidate for teams seeking bullpen help without a long-term commitment. Law's track record as a solid reliever adds value for this season and the next.
