Boston Red Sox infielder Marcelo Mayer (wrist) still hasn't resumed baseball activities since he received an anti-inflammation injection in his ailing right wrist on Aug. 2, Christopher Smith of MassLive.com reports. The Red Sox hoped Mayer would be ready by now, but it appears that surgery is still an option for the 22-year-old rookie. Before a sprained wrist forced him to the 10-day injured list on July 24, Mayer struggled to a .228/.272/.402 line with four homers, 10 RBI, and 20 runs scored in 136 plate appearances. He won't be able to improve on those numbers this season unless his wrist starts responding to treatment.

The Athletics have placed right-hander Luis Severino (oblique) on the 15-day injured list with a strained left oblique and recalled southpaw Hogan Harris from Triple-A Las Vegas. The A's put Severino on the IL retroactive to Aug. 6, though the severity of his injury is unclear. The 31-year-old combined to allow only eight earned runs in 23 innings in his four most recent starts, but his overall production still leaves plenty to be desired. Severino has gone 6-11 with a 4.82 ERA, a 1.34 WHIP, and 103:44 in 136 1/3 innings. His strikeout rate of 6.8 per nine is the lowest of his career. With Severino down, 22-year-old righty Luis Morales will make the first start of his career Sunday against the Baltimore Orioles.

Athletics starting pitcher Luis Morales is scheduled to take the mound for Sunday's game against the Baltimore Orioles. The 22-year-old is set to make his first career start in the big leagues. Morales made one appearance for the A's before this and threw two innings, allowing one earned run on three hits. The expectation is that Morales will have a limited workload on the mound. The right-hander has a tremendous fastball, but control has been an issue for him. There is plenty of long term upside there, but Morales is unlikely to pitch deep into this game. He'll only offer low-end streaming appeal for Sunday's contest.

Detroit Tigers outfielder Wenceel Perez (leg) was forced to make an early exit from Saturday's game against the Los Angeles Angels. Perez fouled a ball off his leg during the second inning of this contest. He stayed in the game, but was eventually replaced by Zach McKinstry in the fifth inning. The expectation is that Perez will undergo further testing to determine the severity of the issue. For now, fantasy managers should consider Perez as day-to-day. He went 2-for-2 at the plate with a single and a triple before exiting the contest.UPDATE: Tests on Perez's right foot came back negative, and he's dealing with a right-foot contusion. It is painful and swollen, but Perez doesn't have structural damage.

Tampa Bay Rays shortstop Taylor Walls (groin) was scratched from the starting lineup ahead of Saturday's game against the Seattle Mariners. Walls reportedly played through a groin issue on Friday, but it was too much for him to play on Saturday. As a result, Walls will be pulled from the lineup, but he might be available off the bench. In his absence, Ha-Seong Kim will take over at shortstop and bat seventh versus right-hander Logan Evans. Fantasy managers should consider Walls as day-to-day until further notice.

Toronto Blue Jays outfielder Joey Loperfido (knee) remains out of the starting lineup ahead of Saturday's game against the Los Angeles Dodgers. This marks the third game in a row that Loperfido has been out of the starting lineup due to a right knee contusion. For now, fantasy managers should consider him day-to-day, but he could land on the injured list if he doesn't get better soon. In the meantime, Davis Schneider, Daulton Varsho, and Myles Straw will cover the outfield on Saturday. Fantasy managers should check back on Sunday for another update on his status.

Minnesota Twins outfielder Trevor Larnach (side) remains out of the starting lineup ahead of Saturday's game against the Kansas City Royals. Larnach will head to the bench for the third straight game while he recovers from a left side injury. He hasn't been placed on the injured list, so for now Larnach should be considered day-to-day. Carson McCusker will cover designated hitter while Alan Roden takes over in left field during Saturday's game. Fantasy managers should check back on Sunday for another update on his status.

The Toronto Blue Jays will continue to evaluate outfielder Anthony Santander (shoulder) "week-to-week" as he recovers from inflammation in his left shoulder, manager John Schneider told reporters. Santander has been on the injured list since May 30, and while he has made progress, he's still not ready to swing a bat. The Jays are holding out hope that Santander will play again this year, but there's no question his first season in Toronto has been a massive letdown. After signing a five-year, $92.5 million contract in free agency last offseason, the former Baltimore Oriole has produced a brutal .179/.273/.304 line with six home runs and 18 RBI in 50 games and 209 plate appearances.

Kansas City Royals second baseman/outfielder Michael Massey (ankle, wrist, back) will begin a Triple-A rehab assignment on Saturday, the team announced. Massey went on the 10-day injured list with a sprained ankle back on June 7, but other issues have set him back in the two months since then. He suffered a hairline wrist fracture on a hit by pitch on June 29, which forced the Royals to shut him down. Massey then restarted a rehab assignment, but the Royals had to remove him from it Aug. 2 after he experienced back tightness. After a recent injection, Massey will attempt to work his way back to the majors once again. The 27-year-old has hit an unsightly .202/.221/.258 with two home runs in 209 plate appearances this season.

Kansas City Royals rookie right-hander Ryan Bergert will make another start for the team on Sunday in the series finale in Minnesota against the division-rival Twins at Target Field. Bergert was acquired from the San Diego Padres at the July 31 trade deadline and allowed two earned runs on two hits while walking two and striking out two in 5 2/3 innings in his Royals debut against the Boston Red Sox on Aug. 5. The 25-year-old former sixth-round pick by the Padres in 2021 out of West Virginia will get another start with his new team, but after that he could be bumped from the rotation with veteran Michael Lorenzen (oblique) nearing his return. Bergert hasn't been anything special in his first MLB season in 2025, but he's more than held his own with a 2.83 ERA (4.15 FIP) and 1.11 WHIP while walking 20 and striking out 36 in 41 1/3 innings over 12 outings (eight starts).

New York Yankees manager Aaron Boone said that he doesn't have a specific timeline for when outfielder Aaron Judge (elbow) will return to the outfield, according to Gary Phillips of the New York Daily News. A report earlier this week suggested that Judge could return to right-field duties either this weekend or early next week, but now it sounds as though the Yankees are in no rush to put him back out there after he spent some time on the injured list with a flexor strain in his right elbow. Giancarlo Stanton is making his first start of the year in the outfield on Saturday against the Astros with Judge still being eased in as the designated hitter. Since returning from the IL on Wednesday, Judge has gone 2-for-10 with an RBI, walk and four strikeouts. Fantasy managers could really care less about when Judge returns on defense, and he remains a must-start in all fantasy lineups.

New York Yankees catcher Austin Wells will get a breather in the second game of the series at Yankee Stadium on Saturday against the visiting Houston Astros with tough left-hander Framber Valdez on the mound. Ben Rice will do the catching for right-hander Luis Gil and will hit fifth against Valdez. Wells is only hitting .209 (64-for-306) on the season, but he's already up to a career-high 15 home runs and 56 RBI for the Yanks in 92 games in his third MLB season. He's actually been better against lefties, too, batting .245 (24-for-98) with five of his 15 homers against them in 2025. Rice has had a breakout season in his first full season in the big leagues with 16 home runs and 36 RBI in his 96 games played in pinstripes. He has never faced Valdez, though, and has gone only 14-for-71 (.197) with four of his 16 long balls against southpaws this year.

Houston Astros infielder Mauricio Dubon and rookie outfielder Cam Smith will both start on the bench for Saturday's game against the New York Yankees in the Bronx. Ramon Urias will make the start for the 'Stros at second base and hit eighth against Yankees right-hander Luis Gil. Jose Altuve is serving as the designated hitter and will bat third, with Taylor Trammell in left field and Jesus Sanchez in right field. Dubon will continue to get at-bats at the keystone for Houston, and he has a hit in each of his last four games played. Smith has gone 4-for-23 with an RBI and five K's in six games so far in August. Sanchez is the one you want to target for DFS lineups on Saturday over Trammell. He has never faced Gil in his career but has gone 8-for-29 (.276) with four doubles and an RBI in his first seven games after the Astros acquired him from the Marlins at the trade deadline.

New York Yankees outfielder Jasson Dominguez is not in the lineup for his team's game against the Houston Astros on Saturday. With Aaron Judge limited to designated hitter duties due to a right flexor strain, Giancarlo Stanton is starting in right field for New York. That pushes Cody Bellinger to left field and Dominguez to the bench. In 374 plate appearances so far this season, Dominguez is hitting .255/.332/.391 with nine home runs, 37 RBI, 50 runs scored, and 19 stolen bases. With Stanton now in the outfield mix, Dominguez could be at increased risk of losing playing time, particularly against left-handed pitching. The 22-year-old is a switch-hitter, but he's hitting just .198 with one home run in 102 plate appearances from the right side of the plate this season.

New York Yankees right-handed reliever Fernando Cruz (oblique) is set to throw a live bullpen session on Sunday at Double-A Somerset. The 35-year-old had recently completed mound work without any setbacks or complications. If he can have a successful session here, there is a good chance that a rehab assignment could take place soon afterward. Cruz has been an outstanding option for the Yankees out of the bullpen this season. Over 33 innings pitched, he has recorded two saves, nine holds, and posted a 41.2% strikeout rate. When he returns, he will join an incredibly talented bullpen, giving New York another solid option near the end of games.

New York Yankees second baseman Jazz Chisholm Jr. is not in the starting lineup for his team's game against the Houston Astros on Saturday. Jose Caballero will take his place at second base and bat eighth against Astros left-hander Framber Valdez. Chisholm Jr. has struggled so far in August, hitting .154 with eight strikeouts in 28 plate appearances this month. He also holds just a .329 slugging percentage against left-handed pitching for the season, which could be part of why he's getting the day off against a tough lefty in Valdez. Chisholm Jr.'s season-long slash line of .237/.329/.461 with 19 home runs and 14 stolen bases is still very solid, so this is likely just a scheduled day off for the 27-year-old.

New York Yankees slugger Giancarlo Stanton is getting his first start in the outfield this season on Saturday against the Houston Astros. Stanton has not appeared in a big-league game in the outfield since 2023. However, with Aaron Judge currently limited to designated hitter duties while he plays through a right flexor strain, the Yankees have been prepping Stanton for defensive work. In 142 plate appearances so far this season, Stanton is slashing .268/.345/.528 with 10 home runs, 28 RBI, and 18 runs scored. The 35-year-old is unlikely to play every day in the field, so his playing time could remain spotty as long as Judge is only able to DH. With Stanton in the lineup on Saturday, Cody Bellinger will shift from right field to left field, and Jasson Dominguez will hit the bench.

Boston Red Sox starting pitcher Walker Buehler did not allow any runs over six innings of work on Friday, yielding four hits and two walks while striking out four batters on the way to earning his seventh win of the year. It was his third quality start in his last five starts, pitching to a 3.21 ERA over that stretch, but it has come with a 1.50 WHIP and a 0.0 percent K-BB%. The 31-year-old has been roughed up to the tune of a 5.40 ERA and 1.56 WHIP with just 75 strikeouts in 100 innings pitched (6.75 K/9) this season. The righty will take on the Astros on the road in his next start on Wednesday, a team he faced recently and allowed three earned runs on nine hits and three walks while not striking out a batter, so he can probably be avoided in DFS.

Kansas City Royals outfielder Mark Canha (elbow) began his rehab assignment with Double-A Northwest Arkansas in a big way, finishing 2-for-4 and hitting a grand slam in the process. It remains to be seen how long he will be rehabbing, but it's a promising sign that his issue with tennis elbow is feeling better after this initial performance. The 36-year-old first baseman/outfielder has only played in 46 games this season, posting a pedestrian .212/.272/.265 slash line while hitting just one home run. When he does return, he will likely continue to be used primarily against left-handed pitchers.

Los Angeles Angels' outfielder Bryce Teodosio (head) left Friday night's game after colliding with the outfield wall in the third inning. The team said after the game that he was feeling better, but that he was still in the process of being evaluated. There should be updates throughout the weekend, but there's a good chance that he misses at least one game while the team figures out the physical well-being of the 26-year-old. Teodosio recently had his contract from Triple-A Salt Lake purchased, and had played in six straight games before the injury. In that time, he has gone 5-14 with three stolen bases. He is someone to consider adding in AL-only leagues, although he appears destined to return to the bench once Jo Adell returns from his injury.
