Fantasy baseball trade candidates to buy/sell for Week 10 (2025). Joey's fantasy baseball undervalued players to target in trades, and overvalued to trade away.

It has been a long couple of weeks for fantasy managers. It feels like the waiver wire continues to get thinner, and more star players are finding themselves on the injured list. Players like Logan Gilbert, Blake Snell, Tyler Glasnow, Yordan Alvarez, and Mike Trout are all currently dealing with different injuries. 

That means it might be time to start making some trades. In this article, we will dive into five players fantasy managers should be looking to buy/sell heading into Week 10 of the fantasy baseball season (June 2 to June 8). 

So, which players should we buy and sell for Week 10? Let's dive in and find out.

Undervalued Fantasy Baseball Players to Trade For

George Kirby, SP, Seattle Mariners 

A lot of fantasy managers are already panicking about Seattle Mariners starting pitcher George Kirby. He hasn't looked like his former self since making his season debut last week, and some could even argue that the Mariners rushed him back too soon. The right-hander has allowed 11 runs across his first 8 2/3 innings this season. 

Kirby started the year on the 15-day IL after experiencing some shoulder soreness early in March. He was then shut down from throwing for a few weeks and slowly worked his way back. Therefore, it's not a surprise to see the 2023 All-Star struggle a bit in his return. His spring was cut short, and it sometimes takes pitchers a few starts to get back into a groove on the mound.

Therefore, the Mariners pitcher is an easy buy-low heading into Week 10. He has finished with a sub-3.55 ERA in each of his three major league seasons while walking just 67 batters in those three years. While Kirby won't generate a lot of strikeouts, he has the potential to finish with double-digit wins, a great ERA, and a low WHIP. 

Fantasy managers shouldn't be overly concerned with his rough start. He'll eventually figure things out and post solid numbers for your fantasy team. So, buy him now before his next outing against a struggling Orioles offense. 

Tanner Scott, RP, Los Angeles Dodgers 

Things can change quickly in the majors. Los Angeles Dodgers closer Tanner Scott had a 1.74 ERA and nine saves through his first 21 games this season. The left-hander, though, has struggled mightily as of late. He has allowed multiple runs in three of his past five appearances, including a blown save in Wednesday's loss to the Cleveland Guardians. 

This recent stretch from Scott has definitely been frustrating for fantasy managers. He has blown three save opportunities over the past 10 days and got hit hard in each of those three relief appearances. The Dodgers' closer will now enter the weekend with an abysmal 4.62 ERA and five blown saves on the year. 

However, the southpaw is the perfect trade target in most leagues. He is the closer on one of the best teams in baseball, and his metrics suggest that he will bounce back. Scott has a 38.1% chase rate, 28.4% whiff rate, 28.3% strikeout rate, and a 3% walk rate to start the season. As long as he remains the team's closer, he will be a player to target in all roto formats. 

Tommy Edman, 2B/OF, Los Angeles Dodgers

Los Angeles Dodgers utility specialist Tommy Edman got off to a strong start in 2025. He was hitting .252 with eight home runs, four doubles, 24 RBI, and two stolen bases in his first 30 games. Edman then landed on the 10-day injured list toward the end of April due to an ankle injury. The 30-year-old spent a few weeks rehabbing that ankle before being activated on May 18. 

However, Edman has not been the same fantasy player since returning. In his nine games back, he is slashing just .129/.182/.161 with one extra-base hit, two RBI, and eight strikeouts. That makes him the perfect trade target heading into Week 10 of the fantasy baseball season. 

Tommy Edman since coming off the IL:

.129 AVG
.182 OBP
.161 SLG
-2 wRC+
2 RBI

Edman missed almost three weeks with that ankle injury and did not go on a rehab assignment prior to his activation. So, seeing him struggle offensively after missing a few weeks is not shocking. 

Fantasy managers should expect Edman to pick things up offensively in the coming weeks. His launch angle sweet-spot rate (39.5%), squared-up (30.4%), and expected slugging (.497) all rank in the top 25% of the league, and we should anticipate him stealing more bases moving forward. The seven-year veteran has an impressive 28.6 ft/sec sprint speed through the first two months. 

Overvalued Fantasy Baseball Players to Trade Away

Tyler Mahle, SP, Texas Rangers

No one expected Texas Rangers starting pitcher Tyler Mahle to throw the ball this well to start the year. The right-hander currently owns a 1.64 ERA and 48 strikeouts through his first 12 starts. His 1.64 ERA ranks fourth in baseball in the early going, only behind Max Fried (1.29), Kris Bubic (1.45), and Nathan Eovaldi (1.56). 

Unfortunately, Mahle's metrics suggest a significant regression is on the horizon for the veteran. His expected ERA (3.81) is 217 points higher than his actual ERA, and his whiff rate (22.2%), walk rate (9.3%), and strikeout rate (18.5%) all rank in the 28th percentile or worse. So, it's only a matter of time until the right-hander has some tougher outings on the mound. 

Although he has a favorable schedule upcoming against the Rays (Week 10) and Twins (Week 11), he is the perfect candidate to sell high. Mahle is throwing his four-seam fastball over 50% of the time this season, and some louder contact should be coming against that pitch in the weeks ahead.

Opposing hitters have an expected .252 batting average and an expected .406 slugging against Mahle's four-seam fastball in 2025. Both of those numbers are way higher than what hitters are currently hitting against it (.177 batting average and .229 slugging). That means you should be looking to trade him away while his value is still high. 

Drew Rasmussen, SP, Tampa Bay Rays

After posting mediocre numbers to start the season, Tampa Bay Rays pitcher Drew Rasmussen has been unstoppable on the mound over the past two weeks. He threw six scoreless innings with five strikeouts against the Marlins on May 17, six scoreless innings with three strikeouts against the Blue Jays on May 23, and six scoreless innings with five punchouts against the Twins in his most recent start. 

That's three straight outings of six shutout innings for the right-hander. He has been dominant in all three of those starts and has walked just three batters during this span. As a result, his rostership continues to climb in all formats. Rasmussen is rostered in 74% of Yahoo! leagues, and that number should grow to over 75% before his next start.

Nevertheless, now is the perfect time to sell Rasmussen. While we shouldn't take away how the right-hander has looked in recent outings, his past three starts have come against the Marlins, Blue Jays, and Twins. All three of those teams rank in the bottom half of the league in runs per game. The right-hander has also had a tough time staying healthy in his career. 

So, start to think about when the best time is to trade him. Some regression could be coming Rasmussen's way, considering his expected batting average against (.254), whiff rate (21.9%), and hard-hit rate (43.7%) all ranked poorly.
