Mariners Top Infield Prospect Michael Arroyo to Join Major Leagues
The Seattle Mariners are promoting top infield prospect Michael Arroyo to the major leagues prior to today's game against the Athletics, according to Daniel Kramer of MLB.com. Arroyo ranked as the Mariners' No. 3 prospect in the latest MLB Pipeline farm system rankings. He was originally signed as an international free agent out of Colombia in 2022. He was promoted from Double-A to Triple-A in the middle of the 2026 season, slashing .283/.359/.471 with 18 home runs, 81 RBI, 17 steals, and 117 wRC+ between the two affiliates. He also racked up an 8.1% walk rate and a 16.4% strikeout rate in the minors. Arroyo played the left side of the infield early in his minor league career, but he has only played second base and left field in 2026. He'll make his MLB debut on Sunday afternoon, batting eighth and playing second base.

Cooper Kupp May See Even Further Workload Reduction in 2026
Across 16 games (15 starts) in 2025, Seattle Seahawks wide receiver Cooper Kupp recorded 47 catches for 593 yards and two touchdowns on 70 targets. While Kupp remained an important piece of Seattle's run to a Super Bowl title, his average of 4.4 targets per game was by far the lowest mark of his nine-year NFL career. Entering 2026, Seahawks WR1 Jaxon Smith-Njigba projects to once again dominate target share in Seattle. Unlike 2025, Kupp may also be behind Seahawks wideout Rashid Shaheed in terms of expected target volume. While Seattle utilized Shaheed in a low-volume, downfield role after acquiring him from the New Orleans Saints at the 2025 trade deadline, Shaheed has reportedly seen much more expansive usage in training camp. As Kupp enters his age-33 season, his days as a must-roster fantasy wide receiver may be behind him.

Kaelen Culpepper Remains Available in Most Leagues Amid Fantastic Start
Minnesota Twins shortstop Kaelen Culpepper has been fantastic at the plate ever since being called up for his MLB debut less than one month ago. Culpepper has played in 24 games (all at shortstop), and he's had no trouble living up to the hype that he possessed as a top prospect. So far, he owns a .307/.361/.466 slash line with three home runs, 10 RBI, a 6.2% walk rate, a 19.6% strikeout rate, and 133 wRC+. He's slugged eight extra-base hits, and although he's walking less than he did in the minors, his strikeout rate hasn't increased by much since his promotion. Culpepper's near-everyday role and impressive offensive contributions have helped him emerge as a top waiver wire option in fantasy baseball. He's still available in 89% of fantasy leagues, and he ranks as the #24 shortstop in RotoBaller's rest-of-season rankings.

Antonio Williams' Path to Immediate Production in Washington May Be Blocked
A third-round pick out of Clemson this past April, Washington Commanders rookie wide receiver Antonio Williams appeared to have a chance to play a significant role in his team's offense at the start of the summer. However, the Commanders' addition of veteran wideout Stefon Diggs in early August may have eliminated Williams' path to high-end usage early on. Between Diggs and star wideout Terry McLaurin, Washington now has two wide receivers who should both easily clear 100+ targets if they are able to stay on the field in 2026. Commanders tight end Chig Okonkwo has recorded at least 50 receptions in three straight seasons and may also be more heavily featured in the Washington pass game than Williams. While Williams remains an intriguing option in dynasty leagues, his redraft value for 2026 could be limited without an injury to the wide receivers ahead of him on the Commanders' depth chart.

Walker Jenkins a Deep-League Waiver Wire Option Despite Quiet Start
Minnesota Twins outfielder Walker Jenkins has been relatively quiet at the plate since being called up for his MLB debut, but he still possesses the upside necessary to be an everyday fantasy baseball option. Therefore, fantasy managers should still consider picking him up off the waiver wire for the month of September, especially in deeper leagues. He owns a .590 OPS through eight games, and he has already recorded both his first home run and his first stolen base. He's striking out at a suboptimal 21.4% clip, but he's also showing on-base skills with his 17.9% walk rate. Over a larger sample size, Jenkins should pan out to be a productive fantasy baseball outfielder. As it stands, he's available to grab off the waiver wire in 89% of leagues.

Travis Hunter a Risky Wide Receiver Option Amidst Major Role Uncertainty
Jacksonville Jaguars cornerback/wide receiver Travis Hunter was an inconsistent producer on offense as a rookie in 2025, recording 29 catches for 298 yards and a touchdown on 45 targets across seven games before suffering a season-ending knee injury. Early reporting out of Jaguars camp this summer indicated that Jacksonville planned to continue using Hunter on both sides of the ball. However, more recent news indicates that the 23-year-old's efforts have been focused almost exclusively on defense as the season draws closer. Deploying Hunter more as a cornerback would make sense for Jacksonville given that the team has three quality wide receivers in Parker Washington, Brian Thomas Jr., and Jakobi Meyers. While Hunter still may see some snaps as a wide receiver, it seems unlikely that he will log enough playing time and/or a large enough target share to be a reliable fantasy wideout in 2026.

Carter Jensen a Priority Waiver Wire Target Amid Hot Stretch
Kansas City Royals catcher Carter Jensen has been swinging a hot bat lately, and he's on the fantasy radar as a very appealing waiver wire target. Over his last six games, Jensen is 9-for-23 with three home runs, six RBI, two walks, and five strikeouts. The bulk of his hits have been of the extra-base variety. In addition to his three homers, he's slugged three doubles and a triple during that six-game window. Over the full season, he has a .755 OPS with 22 homers, a 10.9% walk rate, a 28.1% strikeout rate, and 107 wRC+. Jensen gets the day off Sunday, but he's expected to be back in the lineup Monday against the Diamondbacks. In doing so, he'll look to extend his on-base streak to 12 games. He is rostered in 49% of leagues and currently ranks as the #8 catcher in RotoBaller's rest-of-season fantasy baseball rankings. Managers looking to strengthen or solidify their catcher position should consider picking up Jensen off the waiver wire if he's available.

Oronde Gadsden's Stock Falling Due to Uncertain Role in Los Angeles
A fifth-round pick in the 2025 NFL Draft, Los Angeles Chargers tight end Oronde Gadsden was a pleasant surprise for fantasy managers during his rookie season. Across 15 games (seven starts), the 23-year-old recorded 49 catches for 664 yards and three touchdowns on 69 targets. Despite the encouraging rookie campaign, Gadsden's fantasy value has fallen over the course of the summer. The Chargers added a pair of veteran tight ends in the offseason in Charlie Kolar and David Njoku, both of whom may currently be above Gadsden on the team's depth chart due to their superior skill set as blockers. Los Angeles also has plenty of target competition for Gadsden in its wide receiver corps between wideouts Ladd McConkey, Quentin Johnston, and Tre' Harris. While Gadsden still carries some upside, his lack of a clear role in the Chargers offense makes him a player for redraft managers to avoid ahead of 2026.

Kade Anderson a Key Waiver Wire Target for Final Stretch
Seattle Mariners starting pitcher Kade Anderson was called up to make his MLB debut two weeks ago. His three starts since the call-up haven't been otherworldly, but he still has the strikeout upside necessary to make him an impactful starting pitcher in fantasy baseball for the final stretch of the season. Anderson has a 5.40 ERA through his three starts, but the 3.17 FIP doesn't look quite as bad. The ball-in-play metrics are solid, but we'd like to see him harness his strikeout, walk, and home run rates over a larger sample size. His 6.60 K/9 rate in the majors is essentially half of his rate from the minors this year, and his 4.20 BB/9 and 1.80 HR/9 rates are both key reasons why his ERA is so high. Getting called up midseason could be the main reason why Anderson has been a little shaky in the majors, and we have no concerns about his ability to produce long-term. Meanwhile, in the short-term, there's still a window for him to turn things around if he can attack the strike zone and miss more bats. He's an intriguing stash in September because if he makes those corrections, he'll have a huge fantasy baseball impact. He currently ranks as the #30 starter in RotoBaller's latest rest-of-season fantasy baseball rankings.

Kenyon Sadiq Unlikely to be Immediate Contributor After Injury-Riddled Camp
New York Jets tight end Kenyon Sadiq (hernia) had his first pro camp slightly derailed due to a hernia. The rookie missed most of training camp, as well as all three of the Jets' preseason games. Being available throughout the summer is pivotal for all players, but especially rookies who are trying to adapt to the speed of the NFL while making a good impression. Sadiq's injury has delayed him significantly, making it unlikely that he carves out a fantasy-relevant role early in the season. His age (21) and draft stock (16th overall pick) still make him a must-roster tight end in dynasty leagues, but he's no longer a must-draft player in redraft formats. He has fallen to TE27 in RotoBaller's redraft rankings, and he could slip even further if Mason Taylor handles the bulk of the snaps in Week 1. Sadiq currently has a redraft ADP of 169.4, which corresponds to the 15th round of fantasy drafts and makes him the 23rd tight end off the board. At that same price tag, we'd prefer slightly safer tight ends like Dalton Schultz, Oronde Gadsden II, T.J. Hockenson, and AJ Barner.

Tyler Warren Carries High-End TE1 Upside with Improved QB Health in Indianapolis
Across 17 games as a rookie in 2025, Indianapolis Colts tight end Tyler Warren recorded 76 catches for 817 yards and four touchdowns on 112 targets. The 24-year-old got off to a dominant start to the season, but his production tapered off down the stretch. From Week 12 onward, Warren recorded just one touchdown catch and failed to log more than 43 receiving yards in any game. However, Warren's worst run of the season largely correlated with the health of Colts QB1 Daniel Jones, who suffered a season-ending torn Achilles in Week 14. Heading into 2026, Jones will be back under center for Indianapolis. The Colts also traded away veteran wideout Michael Pittman Jr. over the offseason, which could put Warren in position to be the team's clear number one target in its passing game. Warren carries high-end TE1 potential for fantasy managers into 2026.

Jacory Croskey-Merritt Keeps Building His Case for More Work
Washington Commanders running back Jacory Croskey-Merritt has made a stronger case for more work heading into Year 2. The rushing production was already there after he turned 175 carries into 805 yards and eight touchdowns as a rookie, but the bigger development this summer has come without the ball. Washington senior writer Zach Selby called Croskey-Merritt's pass protection arguably the biggest thing that stood out during a good camp, and that matters after those struggles cost him snaps at times last season. Dan Quinn has also praised the progress he's made as a receiver. A late-August groin injury interrupted things for a bit, but Croskey-Merritt was back on the practice field Sept. 1 and spoke with reporters after practice two days later. Rachaad White still gives Washington another option, especially on passing downs, so this is not suddenly a one-back setup. Still, RotoBaller has moved Croskey-Merritt from RB43 earlier this offseason to RB37 in its Sept. 6 half-PPR rankings. He has done enough this summer to justify the bump.

Keenan Allen Losing Ground in a Crowded Passing Game
Indianapolis Colts wide receiver Keenan Allen doesn't look quite as interesting as he did when he signed in August. Allen was arrested last weekend on misdemeanor charges related to operating a vehicle while intoxicated, though the Colts expect him to play Week 1 and no NFL discipline has been announced. More important for fantasy managers, Alec Pierce is back. Pierce returned from offseason ankle surgery and was a full participant in practice Thursday after spending most of the summer on PUP. He is coming off 1,003 receiving yards, and Allen also has Josh Downs and tight end Tyler Warren fighting for targets. Warren drew 112 of them last season, while Downs had 88. Allen can still get open and caught 81 passes for the Chargers last year, but those receptions produced 777 yards and four touchdowns. RotoBaller currently has him at WR61 in half-PPR formats, behind both Downs and Pierce. There's still a role for Allen here. It just doesn't look like one that needs to carry much fantasy upside.

Jalen McMillan's Redraft Appeal Takes Another Hit
Tampa Bay Buccaneers wide receiver Jalen McMillan (knee) has lost some of the late-round appeal he carried into training camp. He banged up his knee in early August, missed all three preseason games and was still sidelined when Tampa Bay practiced on Sept. 1. The Bucs remain hopeful he'll be ready for Week 1, but this comes right after a 2025 season that was mostly lost to a serious neck injury. McMillan spent months in a restrictive brace before returning in Week 15 and finished the year with 12 catches for 178 yards in four games. That followed a much more encouraging rookie season, when he caught 37 passes for 461 yards and eight touchdowns. There is still room for him in this offense, but the missed summer work matters with Chris Godwin Jr. and Emeka Egbuka holding clearly defined roles and Ted Hurst III and Tez Johnson also in the mix. RotoBaller had McMillan at WR57 in late August. He's down to WR64 in the Sept. 6 half-PPR rankings.

Brandon Aiyuk Keeps Sliding Out of Redraft Relevance
San Francisco 49ers wide receiver Brandon Aiyuk is getting awfully difficult to keep on a redraft board. He remains on the reserve/left squad list as Week 1 approaches, and there has been no movement toward getting him back into the 49ers' offense. Aiyuk hasn't played since Week 7 of 2024, when a torn ACL and MCL ended a seven-game season in which he caught 25 passes for 374 yards and no touchdowns. He then missed all of 2025. At this point, the bigger concern isn't even the knee. There is simply no 2026 role to project while he remains away from the team. RotoBaller had Aiyuk at WR115 in its August half-PPR rankings, and he has since dropped to WR132 in the Sept. 6 update. Something could eventually change with his roster situation, but fantasy managers drafting right now have very little reason to spend a pick waiting for it.
