Texas Rangers shortstop Corey Seager (hamstring) left Tuesday's game early against the division-rival Athletics with right-hamstring tightness. Before leaving, the All-Star shortstop went 1-for-4 at the plate with two runs scored. Josh Smith shifted from center field to shortstop, with Leody Taveras entering the game to play center field. Fantasy managers will be hoping that the Rangers pulled the 30-year-old two-time World Series MVP early as a precaution in an 8-2 ball game, but we won't know more about the severity of Seager's injury until probably Wednesday morning. At the very least, Seager probably won't be in the lineup as the series against the A's continues on Wednesday. If Seager misses extended time, we'd expect Smith to pick up regular playing time at the 6 in Texas. Seager entered Tuesday's contest hitting a strong .288 (21-for-73) with four homers, six RBI and six runs early in the season.

Pittsburgh Pirates left-hander Bailey Falter (back) was removed from his start early on Tuesday against the hosting Los Angeles Angels due to lower-back tightness, according to the team. Falter is currently being treated by the team's medical staff, and the Pirates will provide an update on his condition when new information becomes available. Before departing the contest in Anaheim, Falter had allowed three earned runs on five hits (one homer) while walking none and striking out five in four innings (65 pitches). It's anyone's guess as to whether the 27-year-old southpaw will be able to make his next scheduled start on Sunday against the Los Angeles Dodgers. Even if Falter's injury is minor and he's able to toe the rubber this weekend, fantasy managers will want to avoid him in that matchup. He has been inconsistent so far in 2025 and entered Tuesday's outing with a 4.91 ERA and 1.18 WHIP in his four starts.

San Diego Padres starting pitcher Nick Pivetta pitched seven shutout innings in a 2-0 win over the Tigers on Tuesday. He allowed two hits and two walks while striking out six. This was his third straight quality start and his fourth of the season. Outside of a rough start on April 5 against the Cubs when he gave up three runs in three innings, he's pitched like an ace. In his four other starts, he's allowed just one run in 27 innings with 26 strikeouts compared to only four walks. He'll look to continue his breakout year in his next start, which is currently lined up to be against the Giants.

Philadelphia Phillies outfielder Brandon Marsh (hamstring) ran the bases on Tuesday and feels back to 100 percent. He'll have a rest day on Wednesday and will likely begin a minor-league rehab assignment on Thursday, according to manager Rob Thomson. This is a quick turnaround for the 27-year-old, as he was only officially placed on the 10-day injured list two days ago. It was retroactive to April 17, meaning he would be eligible to return this weekend if his rehab goes well. Hopefully this extended break will help him snap out of his early-season slump, as he's batting just .095 so far through 17 games.

Minnesota Twins starting pitcher Pablo Lopez (hamstring) is nearing a return to the major league rotation. He made a successful rehab start on Saturday, allowing one run on three hits with four strikeouts over 4 innings and 63 pitches. He threw a bullpen session on Tuesday and is happy with where everything is at. There is no official word yet on which day he will make his first start back, but he is eligible to be activated from the injured list on Thursday. He'll look to pick up where he left off before the injury, as he posted a 1.62 ERA and 1.02 WHIP in his first three starts of the year.

Philadelphia Phillies starting pitcher Cristopher Sanchez was pulled from his start after just two innings and 58 pitches due to left forearm soreness. He will be evaluated further before any more updates are given, but this isn't good news for the breakout lefty. The injury was already starting to show itself early in the start, as his velocity was noticeably down a tick to start the game. It looked like he was taking the next step into ace territory in 2025, posting a 2.96 ERA with 31 strikeouts and six walks through his first four starts of the season. Hopefully this injury isn't the worst-case scenario, but more information should be available within the coming days.

Los Angeles Angels infielder Luis Rengifo (mouth) is out of Tuesday's starting lineup against the visiting Pittsburgh Pirates after having a root canal on Monday, according to manager Ron Washington. Rengifo was cleared to play, but Washington wanted Kevin Newman to get a chance to play against Pirates left-hander Bailey Falter, who he has gone 5-for-11 against in his career. Newman is starting at third base and is batting in the nine-hole for the Halos, though, so he will still be a poor choice for DFS lineups with little fantasy upside. Fantasy managers should expect Rengifo to return to the Angels' starting lineup at third base on Wednesday. The 28-year-old Venezuelan infielder has gotten off to a slow start offensively in 2025, going 17-for-78 (.218) with a homer, seven RBI, no steals and eight runs scored in his first 21 games played.

The New York Yankees announced on Tuesday that they signed left-hander Tyler Matzek to a major-league contract and selected him to their active roster and designated right-hander Yoendrys Gomez for assignment in a corresponding move. The Yankees signed Matzek to a minor-league deal back in February, but now he'll join their big-league bullpen for the time being. The 34-year-old veteran southpaw began the season in the minors due to an oblique injury that he suffered in spring training in March, but now he's past the issue and will provide New York with a lefty arm out of their 'pen. In 5 2/3 relief innings for Single-A Tampa and Triple-A Scranton/Wilkes-Barre this year, he gave up two earned runs while walking two and striking out seven. Matzek has a 3.72 career ERA, 1.36 WHIP and just one save in his six major-league seasons.

Cincinnati Reds left-hander Wade Miley (elbow) is starting his minor-league rehab assignment on Tuesday night with High-A Dayton, according to The Cincinnati Enquirer's Charlie Goldsmith. Miley continues his recovery from an internal-brace procedure/Tommy John surgery last May and still has a long ways to go before he's considered an option for the Reds' major-league starting rotation. Even if the 38-year-old veteran soft-tosser makes it back to the big leagues in the first half of the 2025 season, he's not going to present fantasy managers with much upside, if any at all, in the strikeout department. Those in mixed leagues should have more attractive options to choose from. Miley only made two starts for the Milwaukee Brewers before being shut down in 2024 and has a career 7.0 K/9 in 14 MLB seasons.

Cincinnati Reds left-handed reliever Sam Moll (shoulder) is starting his minor-league rehab assignment on Tuesday with Triple-A Louisville, according to The Cincinnati Enquirer's Gordon Wittenmyer. Moll is working his way back since landing on the injured list in the middle of April due to an impingement in his left shoulder, but he's getting closer to making a return to Cincinnati's bullpen. The 33-year-old veteran southpaw isn't a fantasy asset, though, especially after a rough start to his 2025 campaign with four earned runs allowed in two innings pitched as well as three walks and one strikeout. When he's activated from the injured list, Moll will operate in a middle-relief role. In his six seasons in the majors, he has a 3.60 ERA, 1.28 WHIP, one save and a 168:77 K:BB in 162 1/3 innings pitched.

Cincinnati Reds catcher Tyler Stephenson (oblique) is starting his minor-league rehab assignment with Triple-A Louisville on Tuesday, according to The Cincinnati Enquirer's Gordon Wittenmyer. Stephenson worked out with Louisville over the weekend and is now ready to return to game action this week. The 28-year-old backstop hasn't played in a game since spring training in mid-March and opened the year on the 10-day injured list, so the Reds won't rush him back. In the meantime, veteran Jose Trevino will continue to operate as Cincy's primary catcher at the major-league level, with Austin Wynns backing him up. Although he has yet to make is 2025 debut, Stephenson is worth stashing in all fantasy leagues as one of the better power-hitting catchers in the league when he's healthy. He had a career-high 19 long balls and drove in 66 runs in 138 games in 2024.

Texas Rangers second baseman Marcus Semien is being dropped to fifth in the batting order for Tuesday's contest against the hosting Athletics and right-hander Osvaldo Bido. It's the first time that Semien has hit lower than third in the lineup since joining the Rangers back in 2022, and it comes with Semien entering Tuesday's tilt with a .141/.209/.192 slash line, only one home run, six RBI and five runs scored in his first 78 at-bats of the 2025 season. The good news, though, is that he has recorded a hit in four of his last five games. With the 34-year-old veteran moving down the batting order temporarily, utility man Josh Smith will start in center field and bat leadoff for a Rangers offense that is looking to shake things up. Fantasy managers can only hope the drop in the batting order can get Semien going. He has a hit in just two career at-bats against Bido.

The Baltimore Orioles announced on Tuesday that they placed right-hander Cody Poteet (shoulder) on the 15-day injured list (retroactive to April 21) with right-shoulder inflammation and recalled right-hander Brandon Young from Triple-A Norfolk in a corresponding move. Poteet's right shoulder was apparently giving him problems in his first outing of the season on Sunday against the Cincinnati Reds, when he allowed five earned runs on six hits while walking two and striking out one in 2 2/3 innings of work out of the bullpen in a 24-2 shellacking. It's unclear how long the 30-year-old veteran reliever will be on the injured list, but fantasy managers can continue to ignore him whenever he gets back. Poteet has never thrown more than 30 2/3 innings at the big-league level since debuting with the Miami Marlins back in 2021.

The Double-A Chesapeake Baysox announced that Baltimore Orioles left-hander Trevor Rogers (knee) will make his first minor-league rehab appearance for them on Wednesday against the Double-A Altoona Curve. Rogers has been rehabbing from a subluxation of his right knee that he suffered way back in January, and he's now ready to pitch in games as he attempts to make his way back to the Orioles' starting rotation. However, the 27-year-old southpaw is expected to need a lengthy rehab assignment that could stretch well into May. Even when Rogers is deemed fully healthy, there's no guarantee he'll have a rotation spot waiting for him at the big-league level. The former first-rounder by the Miami Marlins in 2017 had a rough 7.11 ERA and 1.84 WHIP in four starts for the O's late last year and was eventually shipped to the minors.

In his third minor-league start on Sunday, Baltimore Orioles right-hander Kyle Gibson went five innings and allowed two runs (one earned) while allowing a solo home run, walking two and striking out five to pick up a win for High-A Aberdeen. Gibson isn't injured, but he opened the 2025 season in the minors to build up his arm after not appearing in any spring training games after signing with Baltimore late. The 37-year-old veteran has now allowed six runs (five earned) on 10 hits (one homer) while walking two and striking out 13 in 12 innings over his three starts (two with Triple-A Norfolk). He was able to throw 51 of his 78 pitches on Easter Sunday for strikes, and he could only need one more minor-league tune-up before the Orioles are ready to have him join the big-league roster. When he joins Baltimore's rotation, he'll be an innings-eater for those in AL-only fantasy leagues at the very least.

Toronto Blue Jays outfielder Daulton Varsho (shoulder) is joining the Triple-A Buffalo Bisons on his minor-league rehab assignment on Tuesday, according to Sportsnet's Arden Zwelling. The hope is that he will play five of the remaining six days this week, with a potential return to the big leagues this weekend in New York against the Yankees as a possibility. Toronto will re-evaluate the 28-year-old on Wednesday or Thursday to make a final call. Varsho is nearing his 2025 debut after having right-shoulder surgery in the offseason. In two rehab games with Single-A Dunedin, he went hitless in six at-bats with two strikeouts, and the Blue Jays want to see a little more before activating him from the injured list. Varsho will probably be eased in when he returns to the majors, but eventually he'll be the team's everyday center fielder.

Toronto Blue Jays right-hander Max Scherzer (thumb) rejoined the team in Houston this week and was seen playing catch before their game against the Astros on Monday at Daikin Park. Scherzer received a second cortisone shot in his troublesome right thumb (in the knuckle area) and is hoping it will alleviate the discomfort in his finger. Pitching coach Pete Walker said Scherzer felt his throwing session went "OK." It was the first time that the 40-year-old future Hall of Famer had thrown since receiving a second cortisone shot. We should know more in a couple of days based on how Scherzer is feeling. If he's cleared to progress to throwing bullpens and facing live hitters, he will eventually need to go on a minor-league rehab assignment before rejoining Toronto's starting rotation. Barring a setback, that might not be until mid- to late-May.

Toronto Blue Jays outfielder/designated hitter Anthony Santander will start on the bench in Tuesday's contest against the hosting Houston Astros. Vladimir Guerrero Jr. will serve as the DH and bat second, while Will Wagner will draw into the lineup at first base and hit seventh against Astros right-hander Ronel Blanco. Tuesday will be Santander's first game off of the season and will give him a much-needed break after he's gone 18-for-92 (.196) with two home runs, eight RBI, seven runs scored and 23 strikeouts in 102 plate appearances over his 23 games played. In the last four games, he has just one hit in 15 at-bats. Fantasy managers will be hoping the day off can get the Venezuelan slugger going at the plate. Guerrero is a must-start in fantasy each and every day, but he has only two hits in 10 career at-bats against Blanco.

The Arizona Diamondbacks optioned center fielder Jake McCarthy to Triple-A Reno during their day off on Monday. Due to McCarthy's slow start to the 2025 season at the plate, Alek Thomas is now the team's go-to option in center field. The 27-year-old former first-rounder will surely be back up with the D-backs this year, but for now he'll head to the farm to work on his hitting after going 3-for-41 (.073) with a double, three RBI, one stolen base, two runs scored, four walks and six strikeouts in his first 14 games played for Arizona. Meanwhile, Thomas, who played in only 39 games in his third big-league season in 2024 due to injuries, has hit .283/.350/.415 with a career-best .765 OPS, three doubles, two triples, 10 RBI, three steals and seven runs scored in 17 games over his first 60 plate appearances. Thomas' stock in deep-mixed and NL-only leagues is certainly on the rise.

Arizona Diamondbacks left-handed reliever A.J. Puk (elbow) underwent an MRI exam on Monday on his injured left elbow, which will determine if he'll need to be out longer than 15 days after being placed on the injured list over the weekend with left-elbow inflammation. Puk already has four saves in eight appearances out of the bullpen in his first full season with Arizona, but he'll now be forced to miss at least the next two weeks while his elbow calms down. The 29-year-old southpaw needs to be stashed in an IL spot while he recovers. Right-hander Justin Martinez should see the majority of save chances for the Snakes while Puk is sidelined, although he was unavailable on Sunday due to a recent heavy workload, which led to Drey Jameson picking up the save over the Chicago Cubs.UPDATE: Lovullo said Puk is seeking multiple opinions after his MRI exam on Monday, which is an ominous sign.
