May 12, 2026

Joey's fantasy baseball buy low, sell high trade advice for Week 7 of 2026. His undervalued fantasy baseball trade targets and overvalued players to trade away.

Welcome, RotoBallers, to our weekly buy/sell fantasy baseball trades advice article for Week 7 of the 2026 season, highlighting the best players to trade for and trade away. If you are new to this weekly series, we look at the best players to buy-low and sell-high each week of the fantasy baseball season. 

In this week's edition, we will dive into the five best trade candidates. The three buy-low players have not provided much in fantasy recently, but should return to their fantasy value within the next few weeks. The two sell-high players on this list are currently overperforming and will not keep this up for the remainder of the season. 

So, which players should fantasy managers buy and sell for Week 7 of the fantasy baseball season? Let's find out.

Undervalued Fantasy Baseball Players to Trade For

Ketel Marte, 2B, Arizona Diamondbacks

Arizona Diamondbacks second baseman Ketel Marte is the best buy-low hitter in all fantasy formats in Week 7. Marte has not gotten off to a strong start at the plate this season, as he is currently hitting .213 with five home runs, five doubles, and 15 RBI in his first 38 games. He is also in a 7-for-45 slump with five extra-base hits and 10 strikeouts in his last 12 games.

However, Marte's metrics suggest better days are ahead for him offensively. His expected batting average (.290) is 77 points higher than his actual batting average (.213), and his xwOBA (.348), expected slugging (.459), average exit velocity (91.3 mph), and hard-hit rate (45.7%) all rank in the 70th percentile or better in the early going. Those metrics prove just how unlucky the veteran has been at the plate so far this season.

That's why he is such a great buy-low option. He has been one of the best-hitting second basemen in all of baseball over the past few years and should eventually return to that fantasy stardom in the next few weeks. This is the same hitter who has hit above .280 with 25+ home runs and 70+ RBI in back-to-back seasons. Trust his track record and trade for him while his fantasy value is so low.

Gunnar Henderson, SS, Baltimore Orioles

There are some major concerns with Baltimore Orioles shortstop Gunnar Henderson's bat right now. His strikeout rate is way up (30.1%), his walk rate is way down (7%), and his other metrics like expected batting average (.222), wxOBA (.289), and squared-up rate (21%) all rank in the bottom 20% among all qualified hitters.

Those poor metrics have Henderson in a rough spot in the early portion of the 2026 season. He's slashing just .206/.263/.411 with nine home runs, seven doubles, 21 RBI, 13 walks, five stolen bases, and a .674 OPS in his first 41 games this year. While the home run numbers are there, everything else is not. It really feels like the Orioles shortstop is swinging for the fences every time he steps to the plate.

But despite all that, this is a massive buy-low opportunity. Henderson is still hitting the ball hard (44.8%), and his barrel rate (9.5%) currently ranks in the 60th percentile. He is also on pace to post his second 20+ home run, 20+ stolen base season of his career. That should be enough reason to buy the lefty slugger in all formats in Week 7 of the fantasy baseball season.

It hasn't been pretty early on, however, Henderson will eventually figure things out at the plate. He's too talented not to. Just two seasons ago, he hit .281 with 37 home runs, 92 RBI, and 21 stolen bases en route to a breakout campaign.

Jesus Luzardo, SP, Philadelphia Phillies

This is the second time that Philadelphia Phillies starting pitcher Jesus Luzardo has been featured on this list this season. He remains a massive buy-low in all formats and is the best pitcher to target in trade negotiations this week. Don't wait too long to trade for him because his buy-low window could close very soon.

Even though Luzardo has a 5.98 ERA across 43 2/3 innings pitched this season, his metrics tell a whole different story. His expected ERA (3.19) is 279 points lower than his actual ERA (5.98), and his average exit velocity (85.9 mph), chase rate (37.2%), whiff rate (33.8%), strikeout rate (30%), walk rate (6.3%), and hard-hit rate (29.4%) all rank in the top 25% of the league.

If you only showed someone his Baseball Savant page, you would think this pitcher is dominating on the mound. He continues to get swings and misses at an elite clip, isn't allowing much hard contact, and his expected FIP sits at 2.40 on the season. That all means some positive regression should head Luzardo's way within the next few weeks.

Therefore, he's a must-buy in all fantasy leagues. He has gotten a bit unlucky on the mound so far, and things should eventually even out for him moving forward.

Overvalued Fantasy Baseball Players to Trade Away

Clay Holmes, SP, New York Mets

New York Mets starting pitcher Clay Holmes deserves some credit for the way he has thrown the ball this season. He has a 1.86 ERA across his first eight starts and has thrown a quality start in three of his last four outings. Some notable performances from him so far include seven shutout innings with four strikeouts against the Giants on April 4 and six scoreless innings with six strikeouts against the Nationals on April 28.

Unfortunately, some negative regression is coming for Holmes, which makes now the best time to sell the right-hander. His expected ERA (3.74) is 188 points higher than his actual ERA (3.74), and his expected batting average against (.252), average exit velocity (89.4 mph), whiff rate (22%), strikeout rate (19.3%), and hard-hit rate (43.5%) all rank in the bottom half of the league.

Considering Holmes is allowing a lot of hard contact and not generating a lot of swings and misses on his pitches, now is the perfect time to get rid of him. Only one of his pitches has over a 30% whiff rate (sweeper), and his next two starts are against the New York Yankees and Washington Nationals. Both the Yankees (5.17 runs per game) and Nationals (5.29 runs per game) rank top-5 in runs scored this season.

So, trade him away before those two starts.

Eduardo Rodriguez, SP, Arizona Diamondbacks

Arizona Diamondbacks starting pitcher Eduardo Rodriguez is pitching like the pitcher he was earlier in his career. He currently owns a 2.25 ERA across his first eight starts, has been able to keep his WHIP down (1.208), and is coming off two vintage performances against the Mets and Pittsburgh Pirates. In those two outings combined, Rodriguez allowed just one run on six hits with 11 strikeouts across 15 1/3 innings pitched.

The left-hander has been on another level on the mound to start the 2026 season. He has thrown a quality start in four of his eight starts and allowed zero earned runs against both the Los Angeles Dodgers (March 28) and Atlanta Braves (May 3) earlier in the year. That has led Rodriguez to be one of the most added pitchers in Yahoo! formats over the past week.

However, the 33-year-old is clearly overperforming at this point in the season. Both his expected ERA (4.59) and expected FIP (4.70) are much higher than his actual ERA (2.25), and Rodriguez has been extremely lucky to begin the year. He enters the week ranking in the ninth percentile in whiff rate (18.3%), 18th percentile in strikeout rate (16.5%), and 28th percentile in walk rate (11%).

With some massive regression coming his way, try to ship him for anything. He's not going to be pitching this well for the remainder of the 2026 campaign.
