Joey's fantasy baseball buy low, sell high trade advice for Week 11 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 11 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 and sell every week of the fantasy baseball season. 

This week, there will be a new set of buy-low and sell-high candidates. All five players on this list are rostered in over 65% of Yahoo! leagues, and some former All-Stars are featured below. The three buy-low players will have better fantasy days ahead, while the two sell-high players are currently overperforming. 

Which players should fantasy managers buy and sell for Week 11 of the fantasy baseball season? Let's find out. All stats are through games played on June 7.

Undervalued Fantasy Baseball Players to Trade For

George Kirby, SP, Seattle Mariners

Seattle Mariners starting pitcher George Kirby was a consistent fantasy option through the first seven weeks of the season. He had a 2.84 ERA in his first nine starts and threw a quality start in five of those nine outings. Kirby even pitched into the eighth inning in two separate starts on April 7 against the Rangers and April 13 against the Astros.

But the right-hander has been hit hard in his last few outings. He has allowed 17 earned runs in his last 21 innings of work (7.29 ERA) and just gave up five runs (four earned runs) on nine hits across four innings against the Mets last week. That outing marked the third time since May 17 that Kirby has given up at least four earned runs in a start.

Despite his 7.29 ERA over his last four starts, Kirby is actually a top buy-low candidate this week. He has a 3.83 FIP during this four-start stretch, which actually suggests that he got a bit unlucky on the mound in these outings. The Mariners right-hander also still ranks in the upper half of the league in expected ERA (3.50), chase rate (35.4%), walk rate (5.6%), barrel rate (5%), and Pull AIR rate against (10.5%).

That's enough reason to trade for one of the best command pitchers in the game. Following his shortest start of the season, Kirby's fantasy value will never be lower.

Brent Rooker, OF/DH, Athletics

A lot of fantasy managers have been frustrated with Athletics designated hitter Brent Rooker's production this season. After slashing .262/.335/.479 with 30 home runs, 40 doubles, 92 runs scored, 89 RBI, and six stolen bases across 162 games last year, Rooker's numbers have taken a significant step back in the first 10 weeks of the 2026 campaign.

The 2025 All-Star is slashing just .206/.284/.400 with 10 home runs, four doubles, 19 runs scored, 29 RBI, and two stolen bases in 47 games. While his batting average is nowhere near where it was last season, the power has still been there for Rooker. He has a 91st percentile barrel rate (15.3%) and is still on pace to hit 29 home runs in 2026.

The batting average was a nice boost for Rooker in each of the past two years, but his real value is in the home run department. That should continue the rest of the season. He has an above-average 18.8% Pull AIR rate and has launched three home runs in his last seven games. Considering the Athletics slugger has hit at least 30 home runs in three consecutive seasons, he's a buy-low target in all formats.

Shota Imanaga, SP, Chicago Cubs

It was just a few weeks ago that Chicago Cubs pitcher Shota Imanaga was widely considered a top-15 fantasy pitcher. He had a 2.32 ERA and 59 strikeouts in his first nine starts and was coming off an outing in which he threw seven innings of two-run ball with six strikeouts against the Braves on May 13.

Since then, though, Imanaga has been a completely different pitcher. He has a whopping 10.80 ERA with only 15 strikeouts in his last four starts and has allowed 26 earned runs over his last 21 2/3 innings pitched. Even his FIP (10.17) during this recent stretch has been poor. The problem for the Cubs left-hander recently has been the long balls, as he has given up 12 home runs since May 18.

Nevertheless, the Japanese southpaw is worth trading for at this point in the season. His expected ERA (3.87) is 87 points lower than his actual ERA (4.74), and his swing-and-miss stuff has been on display in his 13 starts. Imanaga currently ranks in the 94th percentile in chase rate (36.4%), 86th percentile in whiff rate (30.3%), and 62nd percentile in strikeout rate (24%).

The home runs have obviously played a major part in his recent numbers on the mound. But Imanaga did look good for the most part in his most recent outing against the Athletics despite his six runs allowed. Things just went awry for the Cubs' lefty when Pete Crow-Armstrong lost a fly ball in the lights that resulted in a two-run inside-the-park homer in the sixth inning.

Overvalued Fantasy Baseball Players to Trade Away

Liam Hicks, C/1B, Miami Marlins

Miami Marlins catcher Liam Hicks has been an overall solid fantasy option in his second Major League season. He is batting .262 with 12 home runs, five doubles, 47 RBI, and one stolen base in his first 63 games and has emerged as a top fantasy catcher in Week 11 of the fantasy baseball season. Hicks currently ranks as the fifth overall catcher in standard Fantrax leagues.

However, Hicks is someone fantasy managers should consider selling while his fantasy value is so high. Some negative regression is definitely headed his way within the next few weeks. For starters, the lefty slugger has not been hitting as well at the plate. The Marlins catcher is batting just .179 with one double, three home runs, and five RBI over his last 17 games since May 20.

Additionally, Hicks' metrics are a bit worrisome moving forward. His expected slugging (.378) is 83 points lower than his actual slugging (.461), and he currently ranks in the bottom 25% of the league in average exit velocity (86.1 mph), barrel rate (4.8%), hard-hit rate (33.3%), launch angle sweet-spot rate (26.3%), and bat speed (68.1 mph).

That's why Hicks is a top sell-high candidate for Week 11. It's hard to imagine him keeping up these power numbers with a 22nd percentile barrel rate and a poor hard-hit rate.

Justin Wrobleski, RP/SP, Los Angeles Dodgers

Los Angeles Dodgers pitcher Justin Wrobleski deserves a ton of credit for the way he has pitched this season. Outside of a few rough outings in the middle of May, Wrobleski has been dominant. He tossed eight shutout innings against the Mets on April 13, threw seven innings of one-run ball with a career-high nine strikeouts against the Phillies on May 29, and recently threw six shutout innings against the Diamondbacks.

Unfortunately, massive regression is coming the left-hander's way in the near future. His expected batting average against (.258), average exit velocity (89.9 mph), whiff rate (17.2%), strikeout rate (16.1%), and hard-hit rate (42.5%) all rank in the 30th percentile or worse. Wrobleski is also allowing a lot of contact in the air on hitters' pullside at 14%.

The southpaw's numbers will eventually come down following a nice start to the season. His expected ERA (3.87) is 125 points higher than his actual ERA (2.62), and Wrobleski possesses an incredibly low 7.8% swinging strike rate. There are so many negatives with his game right now that selling him makes the most sense.
