June 2, 2026

Joey's fantasy baseball buy low, sell high trade advice for Week 10 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 10 of the 2026 season, highlighting the best players to trade for and trade away. If you are new here, we look at the best players to buy and sell each week of the fantasy baseball season. 

This week's edition features some big-time players. We will dive into three buy-low players and two sell-high pitchers. The three buy-low candidates are all rostered in over 85% of Yahoo! leagues, and the two sell-high candidates are due for some negative regression within the next few weeks. We'll analyze each of these five players and explain why they are buy-lows or sell-highs. 

So, which players should fantasy managers buy and sell for Week 10 of the fantasy baseball season? Let's dive in and find out.

Undervalued Fantasy Baseball Players to Trade For

Nico Hoerner, 2B, Chicago Cubs

There's no denying that Chicago Cubs second baseman Nico Hoerner had a brutal May. After hitting .291 with four home runs, eight doubles, 26 RBI, and seven stolen bases across 31 games in March/April, Hoerner was a completely different hitter this past month. He slashed only .207/.294/.252 with five doubles, seven RBI, and four stolen bases in 28 May games.

This recent slump now gives fantasy managers a key opportunity to trade for one of the best contact hitters in the game. While he won't provide much in the home run department, Hoerner will provide strong batting average, stolen base, and runs scored numbers. Just last year, he hit .297 with 29 stolen bases and 89 runs scored across 156 games.

His 2026 metrics also suggest that he will return to being that all-around fantasy player in the near future. His expected batting average (.296), launch angle sweet-spot rate (38%), squared-up rate (35.5%), strikeout rate (7.4%), and sprint speed (28.4 ft/sec) all currently rank in the 80th percentile or better.

That's enough reason to trade for Hoerner in all fantasy leagues right now. He won't be hitting this poorly the rest of the year. His batting average will eventually climb, and the stolen base numbers should stay steady throughout the year.

Spencer Strider, SP, Atlanta Braves

Atlanta Braves starting pitcher Spencer Strider has not quite gotten into form yet after starting the year on the injured list. Strider has given up nine earned runs in his last 16 1/3 innings pitched (4.96 ERA) and has allowed at least three runs in four of his six starts this season. In his most recent outing on Sunday against the Reds, he allowed four runs (three earned runs) on seven hits with eight strikeouts across five innings.

With Strider still figuring things out on the mound, now is the perfect time to buy low on him. His expected ERA (2.90) is 87 points lower than his actual ERA (3.77), and his expected batting average against (.172), whiff rate (34.1%), and strikeout rate (31.5%) all rank in the top 6% of the league. Those three metrics are a clear sign that better days are ahead for the Braves starter.

It has been a while since Strider has been a consistent fantasy option. He practically missed the entire 2024 season following elbow surgery and finished with a 4.45 ERA and a 24.3% strikeout rate across 125 1/3 innings in his first season back last year. It's a good sign, though, that both his whiff rate and strikeout rate are closer to where they were back when he finished fourth in National League Cy Young voting in 2023.

That makes Strider the best pitcher to target in trade negotiations in Week 10.

Seiya Suzuki, OF, Chicago Cubs

Fantasy managers have to always be patient when it comes to Chicago Cubs outfielder Seiya Suzuki. When he's in a groove at the plate, he's one of the best outfielders to own in fantasy. When he looks absolutely lost at the plate, he's one of the worst outfielders to own. Unfortunately, Suzuki looks like the latter at the plate right now.

Suzuki is batting just .169 with two doubles, three RBI, and 26 strikeouts in his last 20 games dating back to May 10. Still, he's someone fantasy managers should be looking to trade for in Week 10 of the fantasy baseball season. The Japanese slugger has always been a streaky hitter, and his bat usually heats up as the season goes on.

Suzuki has a career .241/.313/.424 slash line with 16 home runs in 505 plate appearances in May, a .223/.288/.418 slash line with 13 home runs in 312 plate appearances in June, a .261/.329/.444 slash line with 15 home runs in 413 appearances in July, a .272/.354/.447 slash line with 12 home runs in 426 plate appearances in August, and a .312/.403/.547 with 18 home runs in 387 plate appearances in September/October.

It's clear that the Cubs outfielder gets hotter as the summer months come and go. So, trade for him now while his fantasy value is so low.

Overvalued Fantasy Baseball Players to Trade Away

Spencer Arrighetti, SP, Houston Astros

Houston Astros starting pitcher Spencer Arrighetti has arguably been the luckiest pitcher in baseball to start the season. Despite owning a 1.34 ERA and allowing just three earned runs across 29 innings pitched in May (0.93 ERA), some negative regression is headed the right-hander's way. That's why trading him away now is the best move.

Not only has Arrighetti faced subpar offenses like the Rockies, Rangers (twice), and the Cubs (amid a 10-game losing streak) in four of his eight starts, but his metrics do not back up his strong numbers on the mound. His expected ERA (4.66) is 332 points higher than his actual ERA (1.34), and his 27.2% chase rate, 21.7% strikeout rate, and 13.1% walk rate all rank in the bottom half of the league.

Having the third-largest difference between actual ERA and expected ERA among all qualified pitchers in baseball proves just how lucky the Astros right-hander has been on the mound to begin the year. His poor metrics are eventually going to catch up to him, especially since opposing hitters carry a 23.1% Pull AIR rate against him across his 47 innings pitched.

If you are looking to sell a player whose fantasy value is at an all-time high right now, Arrighetti is the one. He has been dominant on the mound in his eight starts, but this dominance won't last forever.

Nick Martinez, SP/RP, Tampa Bay Rays

This is not the first time that Tampa Bay Rays starting pitcher Nick Martinez has found himself on this list. The 35-year-old right-hander is continuing to overperform on the mound and continues to be a major sell-high candidate in all fantasy formats. It's hard to imagine Martinez maintaining this level of pitching with below-average metrics.

The veteran ranks in the 45th percentile in expected ERA (4.12), 16th percentile in batting average against (.274), 10th percentile in whiff rate (18.7%), and 10th percentile in strikeout rate (15.2%). If you simply looked at these numbers, you would assume that this pitcher is struggling on the mound. He's not missing many bats, and opposing hitters seem to be all over him at the plate.

Martinez is an easy bet for some negative regression in the next few weeks. His 250-point difference between his expected ERA (4.12) and actual ERA (1.52) is the 10th-largest among all qualified pitchers, and it's also a major warning sign moving forward. The Rays pitcher is not going to magically become this type of elite pitcher in his ninth Major League season.

Like Arrighetti, the poor metrics will eventually catch up to him.
