Arizona Diamondbacks second baseman Ketel Marte (knee) will be activated from the 10-day injured list before Monday's series opener at home against the Philadelphia Phillies, according to Francys Romero. Marte is expected to serve as the designated hitter against Phillies right-hander Aaron Nola, and he will address his teammates before the game. He failed to show up at Fenway Park on Aug. 17 against the Boston Red Sox, with his teammates and the D-backs' coaching staff left in the dark as to why he did not show up. Arizona placed Marte on the restricted list before he and his agent sat down with general manager Mike Hazen and manager Torey Lovullo to explain that he left the team to have an MRI exam on his left knee. "We're playing good baseball right now," Lovullo said. "We need to keep playing good baseball. I think an apology would galvanize this group. He doesn't know how powerful that would be if he did something like that." The 32-year-old switch-hitting Dominican will return to a .249/.314/.446 slash line with 21 homers, 67 RBI, 65 runs scored, and four steals in 469 at-bats in 2026. Marte is typically a must-start in fantasy, but he has hit just .224 (22-for-98) with a .712 OPS, four homers, four doubles, 13 RBI, 14 runs scored, 12 walks, and 20 strikeouts in 26 games since the All-Star break.--Keith Hernandez

Miami Marlins outfield prospect Kemp Alderman has some pop in his bat and has shown that with the Triple-A Jacksonville Jumbo Shrimp this season. In 340 at bats with Jacksonville this year, Alderman has 18 homers and 56 RBI with 55 runs scored and a .259 batting average. He battled a left wrist injury that caused him to miss time in May and June. The 24-year-old is the No. 8 prospect for Miami with 60-grade power and a 45-grade hit tool. The power can play in the major leagues and look for a potential promotion at some point in September for Alderman. The batting average, however, could be a drag for fantasy managers, but that could be offset by his power potential and his ability to steal a few bases. He is a nice addition with upside in fantasy leagues to close out the season.--Brian Buckey - RotoBaller

Arizona Diamondbacks first base prospect Manuel Pena is adjusting well to Triple-A Reno and looks like a potential stash candidate with the potential for a call-up to Arizona. In 51 games with Reno, Pena is hitting .297 with five homers and 27 RBI with 25 runs scored. Between two levels of the minors this year, Pena has 31 combined homers with 91 RBI and 73 runs scored while hitting a combined .305. Most of that damage was done at Double-A but Pena nonetheless looks like a prime candidate for a promotion as rosters expand. Pena is the No. 29 prospect for the Diamondbacks with 55-grade power and for the most part has outperformed his expectations this season. Look for that to be rewarded with a shot in Arizona this September and the pop in his bat could play for fantasy teams.--Brian Buckey - RotoBaller

Baltimore Orioles pitching prospect Michael Forret pitched well in his start on Saturday for Triple-A Norfolk and has mixed results in his four starts with his new club after a trade from the Tampa Bay Rays at the trade deadline. Forret picked up the loss on Saturday despite pitching five solid innings of two-run ball with two hits allowed and four walks. He did have six strikeouts as a bright point in the outing. Forret had one dud start for Norfolk, allowing eight runs in five innings in one of his outings. Altogether, he is 0-2 with Norfolk. He is the No. 10 prospect for the Orioles with three 55-grade pitches in his fastball, slider, and changeup. The Orioles will likely look for a bit more consistency from the 22-year-old before calling him up and allowing him to have any fantasy relevance this season.--Brian Buckey - RotoBaller

Detroit Tigers infield prospect Max Anderson is having a nice August at Triple-A Toledo amidst a very consistent 2026 season. He has likely done enough to warrant a call-up to Detroit as rosters expand in September. This season at two levels of the minors, Anderson has 16 homers and 55 RBI while hitting .307 with 59 runs scored. The 22-year-old missed almost all of April with a quad injury but has returned to form nicely at Toledo. In April, Anderson is hitting .316 with three homers and 12 RBI. Anderson is the No. 11 prospect for the Tigers and a 50-grade hit tool with 50-grade power. The right-handed hitter has shown the ability to hit for average in the minors with some added pop in his bat. He will likely bring that bat to Detroit at some point this September and be a good source of batting average for fantasy managers.--Brian Buckey - RotoBaller

Detroit Tigers catcher prospect Josue Briceno has played for four minor league teams this season and has most recently logged 15 games at Triple-A Toledo. At Toledo, Briceno is hitting .196 with no homers and seven RBI as he has gotten off to a rough start. In 144 at-bats between the four levels, Briceno has combined to hit nine homers and 29 RBI with a .250 batting average. Briceno is the No. 5 prospect in the Tigers' system and has a 50-grade hit tool with 60-grade power. The power is elite for a catcher and makes Briceno an enticing fantasy prospect. But the Tigers have the productive duo of Dillon Dingler and Eduardo Valencia at the catcher position. Look for Briceno to make his debut next season, and when he does, he will likely be a bit of a drag in the batting average category but carries big-time power potential.--Brian Buckey - RotoBaller

Milwaukee Brewers infield prospect Luke Adams has impressed in his limited time in August at Triple-A Nashville and could get a shot to play with Milwaukee at the big league level this season. Adams missed some time in August with a shoulder injury but has five homers and 12 RBI in 34 at bats with a .294 batting average. Adams has played in just 13 games this month but is back looking healthy and hitting well. The right-handed hitter has 16 homers and 43 RBI between two minor league levels this season while hitting a combined .267. The 22-year-old is the No. 13 prospect in the Milwaukee organization and has a 50-grade hit tool with 50-grade power. Look for Adams to potentially lift the Milwaukee offense at some point in September with his power. He could turn his hot-hitting August into a chance for a big league promotion.--Brian Buckey - RotoBaller

Cincinnati Reds shortstop Elly De La Cruz (quadriceps) was diagnosed with left-quad tightness after he exited in the seventh inning of Sunday's game against the Chicago Cubs. De La Cruz was replaced in the lineup by Ivan Johnson, but not before he went 2-for-4 with a single, a double, a run, and two strikeouts. The 24-year-old owns a .269/.349/.476 slash line with 21 home runs, 60 RBI, 24 steals, a 10.7% walk rate, a 27.0% strikeout rate, and a career-high 125 wRC+ this season. De La Cruz avoided injury throughout the 2024 and 2025 seasons, but he missed three weeks earlier this year due to a right hamstring strain, and now it appears that he's banged up once again. Fantasy managers should stay tuned for additional injury updates from the Reds after Sunday night's game goes final. UPDATE: FOX 19's Charlie Goldsmith reports that De La Cruz has a chance to play in Monday's series opener against the San Diego Padres.--Andersen Pickard

Baltimore Orioles first baseman Pete Alonso (head) is expected to be fine despite leaving Sunday's game early after being hit by a pitch in the helmet. Manager Craig Albernaz told Matt Weyrich of The Baltimore Sun that he was already planning to pinch-run for Alonso before he got hit in the helmet. He also noted that Alonso remained in the dugout after exiting and was behaving like his usual self, so there's no cause for concern. Based on Albernaz's comments, we wouldn't be surprised to see Alonso back in the lineup for the Orioles' next game against the Colorado Rockies tomorrow night. The veteran first baseman is slashing .269/.358/.503 with 32 home runs, 91 RBI, an 11.0% walk rate, a 24.4% strikeout rate, and 141 wRC+. He currently ranks as the #5 first baseman in RotoBaller's rest-of-season fantasy baseball rankings.--Andersen Pickard

The St. Louis Cardinals are promoting catching prospect Leo Bernal to the majors, according to Francys Romero of Beisbol FR. The 22-year-old originally signed with the Cardinals as an international free agent out of Panama in 2021. Up until this point, he had spent the entire season in Triple-A, slashing .279/.364/.469 with 16 home runs, 77 RBI, nine steals, an 11.8% walk rate, a 20.0% strikeout rate, and 116 wRC+ across 100 games. Bernal is a switch-hitter and has made impressive strides from a platoon standpoint this year. Specifically, he improved upon his ability to hit right-handed pitching, bringing his OPS against righties up from .668 to .846 this year. He's also been solid on defense, throwing out 27.4% of base stealers. Bernal should have a chance to carve out significant playing time right away, as both of the Cardinals' active catchers have a sub-.600 OPS.--Andersen Pickard

Boston Red Sox first baseman Willson Contreras (hamstring), who exited during the seventh inning of Sunday's loss against the New York Yankees, was dealing with hamstring tightness, interim manager Chad Tracy told Christopher Smith of MassLive.com. "The hamstring was a little tight," Tracy said. "Just felt like at that point of the game, I don't want to push it. So we got him out of there." It's worth noting that the Red Sox were trailing 6-0 at the time of Contreras' exit, and it's unclear whether he would have been able to keep playing if the score were closer. We wouldn't be surprised to see him get the day off Monday against the Seattle Mariners, and we also can't rule out an IL stint if the injury persists or worsens in the next day. Nick Sogard would be the most likely candidate to play first base in Contreras' absence, but the team could also recall Mickey Gasper from Triple-A.--Andersen Pickard

Seattle Mariners top outfield prospect Lazaro Montes is being called up to the majors, according to Francys Romero of Beisbol FR. The talented outfielder signed with the Mariners as an international free agent out of Cuba in 2022 and has quickly developed within the organization's farm system. Up until this point, Montes had split his 2026 season between Double-A and Triple-A. Through 43 games at the Triple-A level, he was slashing .267/.359/.564 with 13 home runs, an 11.6% walk rate, a 31.3% strikeout rate, and 125 wRC+. Strikeouts are evidently a concern with the 21-year-old, but he makes up for it with incredible power, slugging 38 total homers in the minors this year. There's a strong chance that he could be in the lineup for his MLB debut tomorrow against the Boston Red Sox. Regardless of whether he plays on Monday, he should earn consistent playing time in the thick of the playoff race, as the Mariners are five games back in the AL West.--Andersen Pickard

Los Angeles Dodgers catcher Will Smith (neck) is expected to rejoin the team on Tuesday, according to Sonja Chen of MLB.com. Smith has been out since early June due to a neck injury. He began a rehab assignment on August 25 and appears to be on the verge of returning to the big league roster. His return is a welcoming sight for the Dodgers, who have struggled to find consistent production from the catcher spot lately. This season, Smith is slashing .249/.338/.382 with six home runs and 23 RBI across 52 games. It hasn't been a great year for Smith offensively, but he could be worth scooping up off the waiver wire for fantasy managers seeking help at the catcher spot.--Andy Webb

Los Angeles Angels starting pitcher George Klassen (back) was placed on the 15-day Injured List on Sunday, according to Jeff Fletcher. This is a tough break for the Halos, with Klassen actually pitching pretty well over his first few outings. He owns a 3.67 ERA, 1.63 WHIP, and a 24/21 K/BB ratio across 27 innings of work. The walks have been a problem for Klassen, but he's still worth a stash in deep league formats. The Angels haven't given a timetable for his return to the mound, but this isn't expected to be a long stint on the Injured List. The team hasn't announced who is going to take his spot in the rotation yet.--Andy Webb
