HITTERS
Miguel Vargas, 1B/3B, Chicago White Sox (47% Owned)
A former highly touted prospect, Miguel Vargas may finally be putting it together in 2026.
The raw .213 average does not tell the entire story for Vargas in 2026. Vargas’ batted ball profile (12.8% barrel rate and 43.6% hard hit rate) show signs of massive positive regression (.471 expected slugging percentage and .369 xwOBA). And the counting stats (5 homers, 5 SBs, 20 runs, and 13 RBI) demonstrate his potential to provide fantasy managers a boost across the board.
Mickey Moniak, OF, Colorado Rockies (46% Owned)
Admittedly, I am not the biggest fan of the former first overall pick. But Mickey Moniak has looked the part to start 2026, with 8 homers and a .315/1.050 slash line.
Like most savvy fantasy baseball managers, I always recommend Coors streamers, and Moniak gets 3 home games to end his week.
Cam Smith, OF, Houston Astros (44% Owned)
Although the raw numbers do not show it, Cam Smith looks poised for a breakout in 2026.
Like Vargas, the .231 batting average leaves a lot to be desired, but the 14.5% barrel rate and 44.9% hard hit rate have generated an expected .270 batting average and .467 slugging percentage, pointing to massive positive regression in the near future. And the solid counting stats (3 homers, 4 SBs, 15 runs, and 12 RBI) show he is more than capable to provide solid production across the board.
Carter Jensen, C, Kansas City Royals (39% Owned)
Carter Jensen‘s power has been on full display to start the year, with 6 homers and a .538 slugging percentage through 25 games.
The 22 year old youngster is showing off his elite prospect pedigree, and could ranks amongst the top 2026 fantasy baseball catchers by the end of the year.
Francisco Alvarez, C, New York Mets (35% Owned)
The power-hitting catcher has worked to change his approach at the plate, increasing his walk rate and sharply decreasing his strikeout rate to 19.0%, leading to improved contact and hit skills.
Josh Jung, 3B, Texas Rangers (31% Owned)
Another plate approach improver, Josh Jung has lowered his near 30% career strikeout rate to just 17.7% this season, leading to a .299/.894 slash line to start the year.
Jung broke out in 2023 with 23 homers and a .266 average at just age 25, but has scuffled in the years since. However, plate discipline and approach improvement could bring us back to his peak, if not better.
Angel Martínez, 2B/OF, Cleveland Guardians (25% Owned)
Angel Martinez‘s power-speed combo is already giving fantasy lineups a jolt in 2026.
He’s up to 5 homers and 5 steals with a sharp .282/.851 slash, flashing the same dual-threat profile he showed in the minors with multiple double-digit homer and steal seasons.
Samuel Basallo, C, Baltimore Orioles (21% Owned)
Although no longer playing every day, Samuel Basallo may finally be finding his stride in MLB.
Over the last two weeks, Basallo is batting .313 with a 1.030 OPS and 3 homers. A top preseason target, once Basallo puts it all together, he has the kind of power–on-base combination that can quickly elevate him from a speculative stash to a must-start option in all formats, with the upside to be a difference-maker down the stretch.
Spencer Steer, 1B/OF, Cincinnati Reds (13% Owned)
Spencer Steer has found his groove over the past two weeks, posting a .872 OPS with 2 homers, 6 runs, and a steal. In Week 6, he opens with a three-game set at Great American Ball Park against the Rockies—a top-five park factor boost that keeps him firmly in play.
TJ Rumfield, 1B, Colorado Rockies (7% Owned)
Like his teammate Moniak, TJ Rumfield (3 homers, 16 RBI, .759OPS) wraps up the week at Coors Field, baseball’s most hitter-friendly environment in recent years—a boost that puts his bat firmly on the streaming radar.
Brett Baty, 2B/3B/OF, New York Mets (6% Owned)
Brett Baty has been swinging a hot bat the last week (6/12, 1 homer, 5 RBI, 4 runs, 1.404 OPS), and faces 5 righties in Week 6, 3 of which are against a Nationals team that own the second worst team ERA.
STARTING PITCHERS
Reid Detmers, SP/RP, Los Angeles Angels (49% Owned)
Reid Detmers continues to go unnoticed in 2026, and it is time fantasy managers paid attention.
While the 4.08 ERA is unremarkable on the surface, the underlying indicators are far more encouraging. A significantly improved 2.51 BB/9 alongside a strong 9.73 K/9 points to a more refined, sustainable skill set, and the advanced metrics reinforce that shift—his 3.50 SIERA (22nd among qualified pitchers), 2.76 xERA, and 3.05 FIP all suggest better performance than the ERA indicates. Still just 26, Detmers is entering his prime and may finally be on the verge of the long-awaited breakout fantasy managers have been anticipating for years.
Joey Cantillo, SP/RP, Cleveland Guardians (46% Owned)
Another 26-year-old youngster performing at a high level, Joey Cantillo has quietly put together a strong start to 2026.
Through six turns, he’s posted a solid 3.56 ERA while striking out hitters at an impressive 10.09 K/9 clip. The combination of swing-and-miss stuff and emerging consistency suggests Cantillo is starting to settle into a more reliable major league role, with room for even more growth if the command continues to stabilize. One of my favorite sleepers in 2026, scoop Cantillo now and reap the benefits later.
Noah Schultz, SP, Chicago White Sox (43% Owned)
The 43rd-ranked prospect, Noah Schultz, has already shown the kind of swing-and-miss arsenal that makes him a highly intriguing arm.
Through three starts, Schultz has posted a 3.52 ERA with a strong 10.57 K/9, flashing the upside that has evaluators excited. The control remains the clear question mark, as evidenced by a 5.28 BB/9 that will need to come down for sustained success. Even so, the raw stuff is as advertised, and the combination of strikeout ability and pedigree makes the long-term upside genuinely tantalizing if the command begins to stabilize.
Payton Tolle, SP/RP, Boston Red Sox (42% Owned)
Have yourself a night, Payton Tolle!
In his 2026 debut, the 15th-ranked prospect was sublime, striking out 11 Yankees and allowing just 3 hits over 6 innings of 1-run ball. With a strong prospect pedigree and legitimate frontline upside, Tolle is worth rostering, especially in formats where upside arms are at a premium.
Jack Leiter, SP, Texas Rangers (37% Owned)
Following a bumpy stretch, Jack Leiter has seen his ERA climb to 4.97. However, a deeper look suggests room for improvement and potential positive regression ahead. Leiter is still missing bats at a strong 10.30 K/9 clip, and both his 3.82 FIP and 3.87 xFIP point to performance that’s been better than the surface numbers suggest.
Andrew Painter, SP, Philadelphia Phillies (33% Owned)
Former top-10 prospect Andrew Painter has endured a rocky start through his first five appearances, carrying a 5.25 ERA with a modest 7.88 K/9 that hasn’t quite matched the hype. Still, the underlying profile remains encouraging. His 3.94 xERA and 3.36 FIP both suggest he’s been better than the surface results imply, and his elite pedigree supports the idea that positive regression could be on the way as he settles in.
Spencer Arrighetti, SP, Houston Astros (33% Owned)
Spencer Arrighetti followed up his dominant 10-strikeout outing with a quieter performance, managing just three punchouts over five innings while allowing two runs on the road against the Guardians.
The flash and skill Arrighetti displayed in his debut is more than enough to justify taking a low-risk flier, betting that this waiver-wire arm could develop into a hidden gem.
Kodai Senga, SP, New York Mets (33% Owned)
What happens when the strikeout-happiest team meets one of the most proficient strikeout artists in the game? If you are bold enough to stream Kodai Senga in Week 6, you may find out!
A .413 BABIP has inflated his surface 8.83 ERA, masking a far more competent underlying profile. His advanced metrics tell a different story, with a 3.98 xERA supported by strong strikeout production (11.42 K/9), suggesting the results have been far worse than the skills on display. The walks (5.19 BB/9) are definitely a major concern, but there are few pitchers on the waiver wire right now that have league-altering abilities like Senga.
Yusei Kikuchi, SP, Los Angeles Angels (27% Owned)
Will you get good Yusei Kikuchi or bad Yusei Kikuchi in Week 6? Kikuchi remains the definition of a high-risk, high-reward streamer. The strikeout upside is real (9.93 K/9), and the matchup is appealing against a White Sox offense that owns the third-worst team batting average in 2026.
But the downside is just as pronounced. A 6.21 ERA paired with a 4.03 BB/9 shows how quickly things can unravel if Kikuchi’s command isn’t sharp. The swingy profile makes Kikuchi viable in the right context, but also capable of sinking ratios in a hurry. In other words: the stuff is worth betting on, but the floor is as low as it gets.
Max Meyer, SP, Miami Marlins (22% Owned)
The 10.08 K/9 and 3.51 FIP suggest there’s real underlying quality here, and they make it easy to believe Max Meyer’s 3.96 ERA is a bit misleading. Meyer is missing bats at an above-average clip and doing enough to suppress damage when he’s in the zone, which points to a performance that’s been better than the surface numbers indicate. As the results start to catch up with the peripherals, positive regression feels likely rather than hopeful.
Chase Dollander, SP/RP, Colorado Rockies (21% Owned)
A former first-round pick and once top-25 prospect, Chase Dollander‘s pedigree is already on full display to open 2026.
And while Dollander may call Coors Field home, it hasn’t slowed him down in 2026. Through six appearances and 25 innings, he owns a 2.88 ERA with 11.52 K/9 and a much-improved 2.52 BB/9 after sitting at 4.50 in 2025. The underlying metrics back it up as well, with a 2.82 xERA, 3.35 FIP, and 3.05 xFIP underscoring a strong early breakout.
RELIEF PITCHERS
Tanner Scott, RP, Los Angeles Dodgers (46% Owned)
With news of Edwin Diaz‘s elbow surgery, the Dodgers had a massive hole to fill at the closer position. And as predicted in the Week 5 Closer Report, LA turned to Tanner Scott on Thursday, who easily notched his first save of the season.
The next night, however, proved more adventurous for Scott, who entered a 4–4 game in the ninth but needed just two batters to fall behind 6–4 after surrendering a go-ahead two-run homer, taking the loss. The “good” news for Scott owners is that his competition didn’t inspire much confidence either: Alex Vesia gave up two runs in 0.2 innings, and Blake Treinen coughed up a save in the eighth after allowing three hits and a run.
Seranthony Domínguez, RP, Chicago White Sox (46% Owned)
Seranthony Domínguez is a middle-of-the-road relief pitching that currently has the job for the White Sox. If desperate for saves, Domínguez is a viable option.
Lucas Erceg, RP, Kansas City Royals (42% Owned)
After a rocky patch, Lucas Erceg found his footing Friday and shut the door against the Angels in the ninth for his sixth save, putting him tied for fifth in MLB.
Louis Varland, RP, Toronto Blue Jays (38% Owned)
It finally happened. Manager John Schneider has pulled Jeff Hoffman from the closer role and shifted to a committee approach—for now. In true 2026 Blue Jays fashion, even the obvious frontrunner, Louis Varland, nearly fumbled his shot at seizing control.
Varland, however, remains the obvious priority pickup in Week 6. To date, Varland has a stellar 0.64 ERA and 13.50 K/9 across 14 IP and 13 appearances, which are supported by his 1.56 xERA, 1.01 FIP, and 1.72 xFIP.
Bryan Baker, RP, Tampa Bay Rays (32% Owned)
As Griffin Jax continues his early season struggles, Bryan Baker continues piling up the saves, who is now up to 5 on the season.
Joel Kuhnel, RP, Athletics (26% Owned)
Although not the most talented arms in the Athletics bullpen, Joel Kuhnel still appears to be the preferred option and leads the team with 4 saves.
Brad Keller, RP, Philadelphia Phillies (17% Owned)
Following the news of Jhoan Duran, Brad Keller is assumed to be the short-term preferred ninth inning option.
Enyel De Los Santos, RP, Houston Astros (14% Owned)
The Astros’ bullpen struggles have opened the door for Enyel De Los Santos, who’s emerging as the preferred ninth-inning option.
Ben Brown, SP/RP, Chicago Cubs (7% Owned)
After Daniel Palencia‘s oblique strain, Caleb Thielbar looked set as the closer, notching a win and two saves. But Thielbar’s own injury reopens the door in the Cubs’ bullpen.
Enter Ben Brown, former volatile starter turned reliever in 2026. Brown has excelled so far in a flex role for the Cubs, posting a 2.37 ERA (and near-matching 2.68 FIP) across 19 innings and 8 appearances. Brown has elite putaway stuff and the upside to be a shutdown closer—if he can rein in the control.
Jacob Latz, SP/RP, Texas Rangers (3% Owned)
The fourth Ranger to earn a save this year, Jacob Latz earned his first save of the season on Saturday, striking out one across a hitless ninth inning. Latz has a pristine 1.23 ERA and 0.48 WHIP, and could quickly take control of a muddled Rangers bullpen.
