Jeff McNeil an Everyday Option with Positional Versatility
Athletics infielder Jeff McNeil has delivered an uptick in production lately, making him an intriguing player to target on the waiver wire in deeper fantasy baseball leagues. Since the start of August, he's 38-for-112 (.339) with four homers, seven doubles, 19 RBI, four walks, 12 strikeouts, and five steals. Those numbers are substantially better than his season-long statistics, although his "back of the baseball card" numbers aren't necessarily concerning. This year, he owns a .271/.321/.378 slash line with eight homers, eight steals, 52 RBI, a 6.0% walk rate, an 11.3% strikeout rate, and 89 wRC+. Since the start of August, his slash line and home run total have increased while his strikeout rate has remained relatively constant. Because of his recent improvements at the plate, McNeil is an intriguing fantasy baseball waiver wire target in deeper leagues. He has played mostly first base and second base for the A's, but he also has fantasy eligibility in all three outfield spots. The 34-year-old is currently available to be picked up in 80% of leagues.

Joshua Baez a Slugger to Target on the Waiver Wire
St. Louis Cardinals outfielder Joshua Baez continues to show off his power tool at the major league level. In 22 games since being called up for his MLB debut, Baez is slashing .229/.286/.586 with seven home runs, 15 RBI, a 3.9% walk rate, a 35.1% strikeout rate, and 133 wRC+. The discipline and ball-in-play metrics are worrisome, but his absurd power output has made up for it, especially in fantasy baseball leagues. The only thing to consider is that Baez's 9.1% home run rate is not sustainable long-term, so he'll likely cool off eventually. He had a 7.4% home run rate in Triple-A, and even that proportion was absolutely insane. With that being said, Baez hasn't shown any signs of slowing down lately, so he continues to be a worthwhile waiver wire target. He is available in 73% of leagues and ranks as the #65 outfielder in RotoBaller's rest-of-season rankings.

Mason Montgomery Excelling in Closer Role Lately
Pittsburgh Pirates reliever Mason Montgomery has been excellent lately, solidifying himself as the team's closer and getting onto the fantasy radar as a very intriguing waiver wire target late in the season. Montgomery hadn't logged a save situation this year until June 13, and he didn't pick up his first save until July 11. However, the saves have started to occur en masse, as Montgomery has eight saves since the start of August and four saves over his last five appearances. He has also strung together 18 consecutive scoreless outings dating back to July 27. During that window, he has 14.0 K/9 and just 2.1 BB/9. Simply put, Montgomery has been absolutely phenomenal since the end of July. Fantasy managers are starting to take notice, but he's still available in 73% of leagues, which feels like way too many. He should be a top relief pitching target for fantasy managers on the waiver wire. Montgomery ranks as the #37 reliever in RotoBaller's latest rest-of-season fantasy baseball rankings.

Andrew Painter a Late-Season Waiver-Wire Target Amid Hot Stretch
Philadelphia Phillies starting pitcher Andrew Painter has turned things around lately, and he's back on the fantasy radar as an appealing waiver wire target for the month of September. Painter owns a 5.55 ERA with a 1.37 WHIP over 21 outings this year. However, over just his last seven starts, he has a 3.12 ERA with 8.5 K/9 and just 2.9 BB/9. Two of his last three outings have gone seven innings with one or fewer runs. In his most recent start on Wednesday, he went seven shutout innings with six strikeouts, two hits, and no walks. Painter isn't currently a top-85 starter in RotoBaller's rest-of-season fantasy baseball rankings, but that will change if he continues to pitch at such a high level. There's a real opportunity for fantasy managers to pick up Painter off the waiver wire and reap the rewards going forward. As it stands, he's rostered in just 24% of leagues.

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 Sunday'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.

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.

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.

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.

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.

Edward Florentino Looks the Part Of Young Future Star
Pittsburgh Pirates outfield prospect Edward Florentino homered on Saturday for his second homer in four games with High-A Greensboro. Florentino has had a good minor league season at age 19 between two minor league levels, combining to hit .236 with 27 homers and 84 RBI with 84 runs scored and 11 stolen bases. The left-handed hitter is the No. 2 prospect in the Pirates system with a 50-grade hit tool, 60-grade power, and 55-grade speed. At 6-foot-3 and 200 pounds, Florentino is a bit wiry but has room to put on some more muscle, which will only likely add to his power. His average is a bit low this season, but that could be due to adjusting to the minors in only his third professional season. Signed out of the Dominican Republic, Florentino looks to have high fantasy upside and be a high priority dynasty league pickup.

Josuar Gonzalez Has The Makings of a Fantasy Superstar
San Francisco Giants top shortstop prospect Josuar Gonzalez hit a home run on Saturday night and already has six RBI in the month of September. Since his promotion to Single-A San Jose, Gonzalez, a shortstop prospect, has three homers and 35 RBI in 31 games with a .357 batting average and 13 stolen bases. At just 18 years old, Gonzalez is already showing tons of promise in his second professional season. Gonzalez, a switch hitter, is the top prospect and jewel of the Giants' system with a 55-grade hit tool, 55-grade power, and 65-grade speed. Gonzalez appears to be an elite dynasty option, and while it might take a few years for him to make his major league debut, he has the tools to be a future fantasy star. At the shortstop position, he looks to be a future standout.

Aidan Miller Gets Season Debut Under His Belt
Philadelphia Phillies shortstop prospect Aidan Miller (back) made his season debut on a rehab assignment with Single-A Clearwater on Saturday. The 22-year-old was 1-for-2 at the plate in his debut with a run scored. Miller returned to action on a rehab assignment for his back injury. The right-handed hitter is the No. 2 prospect in the Phillies system and has a well-rounded game with a 55-grade hit tool, 60-grade power, and 50-grade speed. The Phillies first round pick in the 2023 MLB draft out of a Florida high school, Miller has good size at 6-foot-1 and 205 pounds and made it all the way to Triple-A during the 2025 season. With a chance to get some games under his belt at the end of this season, Miller looks to be a solid dynasty league target. He promises to be one of the up-and-coming players at the shortstop position.

Parks Harber A Risky End-of-Season Stash Candidate
San Francisco Giants third base prospect Parks Harber has had a decent season in the minors at age 24, and his promotion to Triple-A Sacramento has been followed by some success. In 41 games at Sacramento, Harber has hit .256 with five homers and 29 RBI to go with 24 runs scored. Harber has flashed his power across two levels of the minors this season with 17 combined homers and 76 RBI with a .273 batting average. The right-handed third base prospect is the No. 13 prospect in the Giants system with a 45-grade hit tool and 55-grade power. Harber has had a decent statistical season across the minors this year, and the Giants could reward him with a late-season promotion even though he didn't get the early September call-up. Harber could also be looking at a 2027 big-league debut if the Giants wait it out and let him begin the season in the big leagues next year.

James Tibbs III Hoping Triple-A Consistency Leads To Big-League Promotion
Los Angeles Dodgers outfield prospect James Tibbs III continues to hit at Triple-A Oklahoma City and completed a very strong month in August, making a promotion to the Dodgers even more possible. Tibbs III launched six homers in 92 August at-bats with 21 RBI and a .326 batting average, to go with 19 runs scored. Tibbs III has been consistently good all season at Triple-A with 28 homers and 98 RBI with a . 298 batting average and 100 runs scored. The left-handed hitter is the No. 7 prospect in the Dodgers system and has a 50-grade hit tool with 55-grade power. At age 23, the Dodgers could determine that Tibbs III is ready for a promotion to the big leagues after such a statistically strong season at Triple-A. Tibbs III is worth a stash in redraft leagues, as his potential is great with his strong overall hitting tools and plus power.

Emmanuel Rodriguez Could Be Sneaky Late-Season Stash
Minnesota Twins outfield prospect Emmanuel Rodriguez is hitting for power in his limited action at Triple-A St. Paul this season. In 45 games at Triple-A, Rodriguez has 11 homers and 31 RBI but is hitting just .252. Rodriguez has battled a bad thumb injury this season, which has limited his game time, but the power in his bat has shown. The 23-year-old left-handed hitter is the No. 5 prospect in the Twins system and has a 45-grade hit tool with 55-grade power and speed. Rodriguez also has seven stolen bases in his little game time this season. Rodriguez has some work to do on his overall hitting and is a batting-average risk for fantasy, but his power-speed combination is real. The Twins have already called up top prospects Walker Jenkins and Kaelen Culpepper, so they might elect to keep Rodriguez in the minors the rest of this season. But if they do look his way for a promotion, he could have some late impact on the fantasy season.
