Miami Marlins outfield prospect
Kemp Alderman has been promoted to Triple-A Jacksonville after a productive showing at Double-A throughout the bulk of the season. The Marlins' 11th-ranked prospect slashed .282/.337/.447 with 15 home runs and 20 stolen bases in 110 games for Pensacola, earning Southern League Player of the Week honors on three separate occasions in 2025. The 23-year-old will play out the remainder of the season with the Jumbo Shrimp, with eyes set on a potential major league debut in 2026. The former second-round draft pick has big-time power, but has shown that he can hit for average as well, and even has the chops to steal bases. With a seemingly complete skillset, if he can continue to produce at Triple-A, he could be a solid under-the-radar piece in dynasty formats.

Athletics starting pitcher
Luis Severino (oblique) is expected to rejoin the team for their upcoming road trip against the St. Louis Cardinals. Severino has been sidelined since August 9 due to a left oblique strain. He appears to be on the verge of returning which is great news for the A's. The right-hander was pitching well over his last few starts before going down. Overall, Severino owns a 4.82 ERA, 1.34 WHIP, and a 103/44 K/BB ratio across 24 starts this season. Severino is probably only worth rostering in deep leagues at the moment.

Cleveland Guardians outfield prospect
George Valera is expected to be promoted to the majors on Monday for what will be his major league debut. The 24-year-old was Cleveland's top-ranked prospect back in 2022, but has since fallen outside the top 30 with a career batting average at Triple-A of .232. At the end of last season, the left-handed slugger ruptured the patellar tendon in his right knee attempting to make a play in right field, but worked his way back and rejoined Triple-A Columbus full-time in July of this year. The Dominican was hitting .255 for Columbus at the time of his call-up, registering a solid .346 OBP thanks to a strong 12.1 percent walk rate, and even hit for the cycle a little over a week ago on August 22. Once projected to be a 25-30 home run prospect, there should be optimism for the potential he brings to Cleveland, however, fantasy managers should take a wait-and-see approach before adding him.

San Francisco Giants relief pitcher
Randy Rodriguez (elbow) will undergo season-ending Tommy John surgery. Rodriguez landed on the 15-day injured list on Tuesday due to a right elbow issue. After further discussion with doctors, Rodriguez has decided to have Tommy John surgery. This operation normally requires 12-to-18 months to recover, so Rodriguez is unlikely to pitch in 2026. This is a tough blow to the Giants as Rodriguez earned his first All-Star selection in 2025. He'll finish with a 1.78 ERA, 0.89 WHIP, and a 67/11 K/BB ratio across 50 appearances this season. The absence of Rodriguez means that
Ryan Walker should remain the closer in San Francisco.

Cincinnati Reds pitcher
Chase Burns (elbow) was able to throw a successful bullpen session on Saturday. The activity included an "up and down" to simulate multiple innings. The session went well, so Burns will likely move to facing live hitters next. The minor league season is nearing an end, so it's unclear if he'll go on a rehab assignment. It still sounds like Burns is a few weeks away, but is hopeful to get back before the end of the season. Burns is worth stashing on the IR until more information is known about his possible return.

Miami Marlins outfield prospect
Victor Mesa Jr. was recalled from Triple-A Jacksonville on Sunday, although he is not in the lineup for the team's afternoon contest against the Mets. The Marlins' 23rd-ranked prospect was activated from the injured list at Triple-A on August 17 and had gone 13-for-35 (.371) in the nine games since activation, including one double, two home runs, 11 RBI, and four runs scored during that stretch. Once a top prospect for Miami, there is potential to hit for power, and with a low 16.8 percent strikeout rate this season, he could hit for average, too, but he's fallen off over the last couple of seasons in the stolen base category. The 23-year-old made a brief debut with the Marlins earlier this year, but if he's not going to get regular at-bats, there is little reason to pick him up in season-long leagues.

Miami Marlins rookie starting pitcher
Ryan Gusto (shoulder) was placed on the 15-day injured list on Sunday, retroactive to Aug. 28. Gusto has been terrible lately, allowing 14 earned runs over his last two starts. It's possible that his shoulder issue was part of the reason he was struggling on the mound. He figures to miss a few weeks of action and honestly could be done for the season given there's basically only a month left. In a corresponding move, right-hander
Freddy Tarnok has been recalled from Triple-A Jacksonville. Gusto can safely be dropped in all fantasy leagues.

Athletics first baseman
Nick Kurtz (oblique) remains out of the starting lineup ahead of Sunday's game against the Texas Rangers. The A's have decided to hold out Kurtz for the rest of the weekend after he suffered an oblique injury on Friday. The MRI didn't reveal any significant damage, so Kurtz should be considered day-to-day. The A's aren't playing for anything at this point in the season, so they'll give Kurtz as much time as he needs to get healthy. It sounds like he'll avoid a trip to the injured list and hopefully return early next week. In the meantime,
Tyler Soderstrom will cover first base and bat cleanup against right-hander
Jacob deGrom on Sunday.

Boston Red Sox outfielder
Wilyer Abreu (calf) isn't recovering as quickly as expected when he went on the 10-day injured list with a strained right calf on Aug. 21. Manager Alex Cora said Sunday that Abreu has "been able to hit and move around defensively. But he hasn't been able to run. So are we concerned? Yes and no. He'll be back at one point. But I think it's been longer than expected." Abreu is scheduled to run on Monday, so the Red Sox will have a better idea of his status then. The 26-year-old is unlikely to return during their current homestand, which runs through Wednesday. The team will start a six-game road trip on Friday. It's less than ideal for the playoff-contending Red Sox to continue going without Abreu, who has been one of their most productive players this year. He has taken 395 trips to the plate and slashed .253/.325/.486 with 22 homers, 69 RBI, 52 runs scored, and six stolen bases.

New York Mets right-handed pitching prospect
Jonah Tong will make the second start of his career on Friday against the Cincinnati Reds. Tong earned the victory in his debut this past Friday against the Miami Marlins, whom he held to one earned run on six hits over five innings. The 22-year-old posted six strikeouts against no walks in that game, and he impressed manager
Carlos Mendoza enough to remain part of a six-man rotation. Tong, who ranks as one of the game's top pitching prospects, led all minor leaguers with an eye-popping 179 strikeouts in 113 2/3 frames before the Mets promoted him. His next opponent, Cincinnati, ranks a decent 14th in the majors in runs this season. However, the Reds' offense has sputtered this month. They rank 29th in both runs and wOBA over the past 30 days. That could bode well for Tong.

Washington Nationals left-hander
Andrew Alvarez will come up from Triple-A Rochester to start against the Miami Marlins on Monday, interim manager Miguel Cairo announced. He'll replace injured southpaw
MacKenzie Gore (shoulder) in the Nationals' rotation for the time being. Alvarez, a 12th-round pick in 2021, will be making his major league debut. The 26-year-old does not rank among the Nationals' top 30 prospects at either MLB Pipeline or Baseball America. Nevertheless, he has pitched to a respectable 4.10 ERA with a 1.35 WHIP, 114 strikeouts, and 52 walks in 123 Triple-A innings this season. On paper, he has a favorable matchup against the Marlins, whose .284 wOBA versus lefties ranks 26th in the majors.

The Toronto Blue Jays have claimed utility player
Isiah Kiner-Falefa off waivers from the Pittsburgh Pirates, Jeff Passan of ESPN reports. Kiner-Falefa spent the first few months of the 2024 season with Toronto before the team traded him to Pittsburgh in July. The 30-year-old, who has never been an offensive threat, hit .264/.300/.332 with one homer, 35 RBI, 40 runs scored, and 15 stolen bases in 428 plate appearances with the Pirates this season. Thanks to his defensive versatility, Kiner-Falefa is a much more useful player in real life than he is in fantasy. He'll provide the AL East-leading Blue Jays with some quality depth down the stretch.

Colorado Rockies rookie first baseman
Warming Bernabel (knee, quad) left a 4-3 loss to the Chicago Cubs early on Saturday with a bruised left knee and quad. He fouled a ball off himself in the second inning and had to exit shortly after that. Bernabel is out of the lineup on Sunday against the Cubs, while
Kyle Farmer will play first and hit sixth in a meeting with left-hander
Matthew Boyd. The Rockies will start a series against the San Francisco Giants on Monday, but it's unclear if Bernabel will return then. Since debuting on July 26, the 23-year-old has slashed .252/.283/.435 with four homers, 13 RBI, and 14 runs scored in 120 plate appearances. He went seven straight games without a hit before singling on Saturday.

The Kansas City Royals announced that they have reinstated right-hander
Michael Wacha (personal) from the paternity list and optioned righty
Stephen Kolek to Triple-A Omaha. Wacha will start Sunday's game against the division-rival Detroit Tigers. Although Wacha's not a great source of strikeouts, the 34-year-old has nonetheless enjoyed another solid season. He has made 26 starts and gone 8-10 with a 3.39 ERA, a 1.18 WHIP, and 108:38 K:BB in 148 2/3 innings. Wacha has already faced the Tigers three times this year and held his own in each outing. The Royals won two of those meetings, and Wacha combined to allow just five earned runs on 16 hits and post 15 strikeouts against two walks over 18 1/3 frames.

The Miami Marlins announced that they have placed outfielder
Dane Myers (oblique) on the 10-day injured list with a strained right oblique and recalled outfielder
Victor Mesa Jr. from Triple-A Jacksonville. Myers suffered the injury in an 11-8 win over the New York Mets on Saturday and had to leave early as a result. This is now the second time Myers has gone on the IL with a right-oblique strain this year. The injury shelved him for approximately three weeks in May. Depending on the severity of this strain, it could end Myers' season. The 29-year-old got off to a promising start in 2025 and owned an .862 OPS as late as June 16, but his production has nosedived in the past two and a half months. He's heading back to the IL with a .233/.292/.325 line, six homers, 27 RBI, 28 runs scored, and 17 stolen bases in 318 plate appearances.
