Los Angeles Dodgers relief pitcher Blake Treinen (lung) is starting a rehab assignment this week, and he will need three or four outings before he's ready to return to the major-league roster. On the mend from a bruised lung that he sustained on March 9, Treinen should be back to help LA's bullpen by the beginning of May. The 35-year-old veteran right-hander missed most of the 2022 campaign and all of last season following shoulder surgery, and while he'll be in line for the occasional save opportunity based on closer Evan Phillips' availability, Treinen's fantasy value will be more pronounced in leagues that count holds. With right-handers Joe Kelly and Ryan Brasier struggling to begin to 2024 regular season, look for Treinen to become the Dodgers' primary righty setup man before long. In his last full season during 2021, Treinen posted a 1.99 ERA (2.88 FIP), 0.98 WHIP, and 85:25 K:BB over 72 2/3 innings.

Detroit Tigers third baseman Gio Urshela (hamstring) was cleared to resume baseball activities on Tuesday. After suffering a Grade 1 right hamstring strain in Friday's win over the Minnesota Twins, Urshela was able to do some straight-line running drills on Tuesday. The fact that the 32-year-old defensive-minded infielder is already progressing from the injury means he should be able to return to the Tigers in early May. Although Urshela was hitting for a .298 batting average (17-for-57) before going down, he has just two extra-base hits and six RBI over 18 games in Detroit's weak lineup and is not a recommended stash in the majority of fantasy leagues. Utility man Matt Vierling will handle the lion's share of the reps at third base until Urshela is back healthy, but fantasy managers can do better on waiver wires.

Los Angeles Angels outfielder Mike Trout is in center field and hitting out of the leadoff spot on Tuesday versus the visiting Baltimore Orioles and right-hander Grayson Rodriguez. It's a notable development, as Trout will be hitting leadoff for the first time since August of 2020. Perhaps it will get the 32-year-old All-Star going, as he's hitting just .111 in his last seven games after a strong start to the season. This setup with Trout at the top of the batting order could continue until third baseman Anthony Rendon (hamstring) returns from a stint on the injured list. Trout's recent slump at the plate has dropped his season slash line to .236/.327/.562 with an .889 OPS, but he's still leading the league with eight home runs while driving in 11 and stealing five bases in 23 games. In six career at-bats against Rodriguez, Trout is hitting .333.

Boston Red Sox manager Alex Cora is giving third baseman Rafael Devers (knee) one more day to rest his knee on Tuesday against the Cleveland Guardians and said Devers will serve as the designated hitter on Wednesday. Devers was originally set to return to Tuesday's lineup, but the Red Sox are being cautious since he hasn't played since suffering a bone bruise on his left knee on April 17. Pablo Reyes is getting the start at third for Boston on Tuesday and is hitting ninth against Guardians right-hander Ben Lively. Reyes, 30, should be avoided in DFS, especially in the nine-hole for the Red Sox. The Dominican infielder has eight hits in 46 at-bats (.174 average) with no homers and four RBI this year. Reyes has hit eight home runs, drove in 53 and stolen 12 bases in his six years in the majors.

Boston Red Sox third baseman Rafael Devers (knee) remains absent from the team's starting lineup on Tuesday against the hosting Cleveland Guardians. Pablo Reyes is getting the start at the hot corner and will hit in the nine-hole against Guardians right-hander Ben Lively, making him a poor sleeper option for DFS lineups. The Red Sox were hoping the Devers could return on Tuesday after a scheduled off day on Monday, but that won't be the case. The 27-year-old could need a trip to the injured list now that he'll be missing his fifth straight game after suffering a bone bruise on his left knee. It's a gamble if you've already inserted him into your weekly fantasy lineup. On top of his injury, Devers is just 9-for-48 (.188) so far in 2024 with two home runs and five RBI.

The Cincinnati Reds have activated left-handed reliever Sam Moll (shoulder) from the injured list on Tuesday. Moll began the season on the injured list due to a shoulder impingement. The left-hander went 2-3 with a 3.03 ERA last season with the Reds in 70 games, including one start. By activating Moll, Cincinnati optioned right-handed pitcher Casey Legumina.

The New York Yankees will be starting right-hander Marcus Stroman on Tuesday against the Oakland Athletics. Stroman is coming off going 5.1 innings allowing two runs on six hits against the Toronto Blue Jays. Stroman is 1-1 with a 2.42 ERA this season, while at home is 0-1 with a 3.27 ERA. The right-hander is going up against an Athletics lineup that is slashing .204/.278/.339 which ranks 28th, 29th, and 26th in the majors.

Right-hander Kevin Gausman will be starting for the Toronto Blue Jays on Tuesday in the second game of their four-game series against the Kansas City Royals. Gausman struggled to begin the year with his velocity, but in his last start against the Yankees, the right-hander had success, as he went five innings and allowed just one run on four hits while striking out six. Gausman is 0-2 with an 8.16 ERA this season and will face a Royals lineup that is slashing .237/.306/.405.

San Francisco Giants right-hander Alex Cobb (hip, shoulder) was moved to the 60-day injured list on April 20, so he won't be eligible to return until May 27. Cobb was progressing well in his rehab from offseason hip surgery, but he hit another minor setback when he felt mild shoulder irritation before throwing a bullpen session on April 16. He "felt OK" when he resumed throwing but saw team orthopedist Dr. Ken Akizuki as a precaution on April 18, according to manager Bob Melvin. Cobb said the imaging on his shoulder came back clean, and he's currently throwing out to 75 feet on flat ground. The 36-year-old also had a "baby setback" when he was briefly shut down with a mild flexor strain in his right elbow. Cobb should have a rotation spot waiting for him when he's healthy, but he can stay on the waiver wire for now in most mixed leagues.

St. Louis Cardinals relief pitcher Keynan Middleton (forearm) has been on a two days on, one day off throwing program and has been stretched out so far to 110 feet. He's not throwing off a mound yet, though. Meanwhile, Drew Rom (biceps) did some plyometric work but didn't respond well late last week and hasn't made any progress from his injury. Middleton should be cleared to throw off a mound again soon and could then move to a short minor-league rehab assignment after that if all goes well. The 30-year-old hasn't pitched since getting hurt on March 7 during spring training, but when healthy, he could have some fantasy value in leagues that count holds. He'll be one of the team's primary setup men in front of closer Ryan Helsley.

The Baltimore Orioles placed outfielder Austin Hays (calf) on the 10-day injured list on Monday, retroactive to Sunday. After leaving Saturday's win over the Kansas City Royals, Hays needs to miss some additional time with a strained left calf. The 28-year-old left fielder was already trending down due to a feeble .111/.200/.111 triple-slash line with just two RBI over 45 at-bats (19 games) as well as the emergence of former top prospect Colton Cowser for the O's, so fantasy managers shouldn't feel inclined to stash Hays while he's sidelined. Cowser's playing time in left field becomes even more solidified in the absence of Hays. Hitting .373 (19-for-51) with five home runs, six doubles, nine runs scored, and three stolen bases to this point, Cowser is a player with five-category upside in Baltimore's potent lineup for the foreseeable future.

San Diego Padres third baseman Manny Machado has been placed on the paternity list on Monday. The superstar infielder will be away from the team for one to three days due to personal matters. In a corresponding move, infielder Matthew Batten has been recalled from Triple-A El Paso. Batten will take over the active spot on the roster and figures to play in a few games until Machado returns. Eguy Rosario is starting at third base and is hitting seventh on Monday against the Colorado Rockies and left-hander Austin Gomber.

New York Yankees starting pitcher Carlos Rodon was tough to hit during Monday's game against the Oakland Athletics. The left-hander threw seven scoreless innings while allowing only one hit in what ended up being a no-decision. Sadly for Rodon, the Yankees offense didn't do much during this game. The Yankees ended up giving up two runs in the ninth inning and lost 2-0. Rodon is posting a solid 2.70 ERA, even though his 22/13 K/BB ratio isn't pretty. Fantasy managers will take this strong outing, but don't expect it every start from Rodon.

Milwaukee Brewers right-hander Jakob Junis (head, shoulder) was hit in the head by a line drive during pre-game batting practice before Monday's contest against the Pittsburgh Pirates. Junis is currently on the 15-day injured list with a right-shoulder injury. He was alert and responsive and was taken for more observation by an ambulance at PNC Park in Pittsburgh. The 31-year-old will surely be put through the league's concussion protocol, and it's unclear right now if his head injury will affect how quickly he'll be able to return from the IL for the Brewers. Junis made just one start on April 2 against the Minnesota Twins before going on the shelf with his shoulder injury. In his lone start, he gave up just one earned run on three hits while walking one and striking out four in four innings for a no-decision.

The Milwaukee Brewers placed left-hander Wade Miley (elbow) on the 15-day injured list (retroactive to April 19) with left-elbow inflammation on Monday. In other moves, the team recalled right-hander Tobias Myers from Triple-A Nashville, reinstated first baseman Jake Bauers from the bereavement list, and optioned infielder Andruw Monasterio to Nashville. The 37-year-old Miley started the 2024 season on the injured list with a left-shoulder injury and he also missed time in 2023 with elbow and lat ailments. Miley is set to undergo tests on Tuesday and could be out for an extended amount of time. Myers is the most logical choice to fill in for Miley on Tuesday and start against the Pittsburgh Pirates. Miley already wasn't really an attractive option for fantasy managers in deep-mixed leagues before the injury.

New York Yankees outfielder Aaron Judge went 0-for-4 with two strikeouts in Monday's 2-0 loss to the Oakland A's. The season hasn't been kind to him, as he is averaging .167 (15-for-90) with five doubles, three homers, 15 runs, 11 RBI, 17 walks, and 31 strikeouts over 23 games. Judge should be able to find some hits within the series against the A's as the matchups favor him and the Yankees. Even with the struggles, Judge is a must-start in all league formats, providing power when he connects.

The Minnesota Twins activated outfielder Max Kepler (knee) from the 10-day injured list on Monday, and he's in the starting lineup right away against the Chicago White Sox and rookie right-hander Jonathan Cannon. Kepler is in right field and is batting fifth. The 31-year-old left-handed hitter looked good on his short minor-league rehab assignment with Triple-A St. Paul and should go back to the strong side of a platoon in right field against right-handed pitchers. His return is bad news for both Trevor Larnach and Carlos Santana moving forward. Fantasy managers using Kepler in deeper leagues will hope he can start swinging the bat like he did on his rehab assignment after getting just one hit in his first 20 at-bats of the season before landing on the IL.

Minnesota Twins outfielder Byron Buxton appears to be getting a day off on Monday against the visiting Chicago White Sox. Austin Martin will take over in center field for the Twins and will hit ninth in the batting order against White Sox rookie right-hander Jonathan Cannon. First baseman Alex Kirilloff will also head leadoff for this one. First baseman Carlos Santana will be the designated hitter. Buxton has so far stayed healthy in 2024, but he's hitting a lowly .217 (15-for-69) with no home runs, nine RBI and no stolen bases in 20 games played. There's still time for the 30-year-old to turns things around, but fantasy managers shouldn't expect frequent running on the base paths to be Buxton's thing anymore. Martin will be a low-upside DFS sleeper in the nine-hole on Monday.

The Cincinnati Reds placed right-hander Frankie Montas (forearm) on the 15-day injured list on Monday with a right-forearm contusion and recalled right-hander Casey Legumina from Triple-A Louisville in a corresponding move. Montas heads to the IL after getting hit in the right forearm by a comebacker in Sunday's game against the Los Angeles Angels. The 31-year-old has a good chance of coming back in two weeks when he's eligible after avoiding a fracture to his arm. With Montas out of action for a few weeks, swingman Nick Martinez will become more attractive in fantasy leagues with a move to the starting rotation. In what Montas' managers are hoping is a bounce-back year, he's so far been inconsistent with a 4.19 ERA, 1.45 WHIP and 14 K's in 19 1/3 innings over five starts.

Atlanta Braves first basemen Matt Olson went 0-for-4 with four strikeouts Sunday against the Texas Rangers. Olson's strikeout issues continue to stack up as he struck out six times in three games over the weekend, finishing 0-for-12 with one run, one RBI, and two walks. The struggles have followed him all season long as he is hitting .231 (18-for-92) with seven doubles, one triple, three homers, 12 runs, 13 RBI, 12 walks, and 26 strikeouts over 20 games. Despite striking out four times on Sunday, Olson remains a must-start in all league formats.
