The Chicago Cubs designated outfielder Garrett Cooper for assignment on Tuesday, according to a source. Cooper wasn't exactly slumping at the plate, but the Cubs think he's expendable in order to bring up first base prospect Matt Mervis as another right-handed bat. The 33-year-old Cooper was hitting .270/.341/.432 with a home run, double, triple, six RBI and three runs scored in 41 trips to the plate and 12 games for the Cubs before getting DFA'd. He had walked four times and struck out 13 times. For now, Mervis is likely to see most of his time as the team's designated hitter, at least until outfielder Seiya Suzuki (oblique) is able to return from the injured list. Mervis is worth a pickup in NL-only leagues for now.

Chicago Cubs outfielder Ian Happ (hamstring) is back in left field and is hitting second for the Cubs on Tuesday against the visiting Houston Astros and right-hander J.P. France. Happ tweaked his hamstring last Friday and sat out Saturday and Sunday. But after the team's scheduled off day on Monday, the 29-year-old switch-hitter is ready to return to Chicago's starting lineup. Happ will be looking to bust out of a recent slump that has seen him record just four hits in his last 35 at-bats now that he's healthy again. Overall this year, he's hitting .240/.352/.360 with a home run, 12 RBI and 14 runs scored in his first 75 at-bats. In his two career at-bats against France, Happ has two hits and an RBI.

The Chicago Cubs placed pitchers Kyle Hendricks (back) and Drew Smyly (hip) on the 15-day injured list on Tuesday and recalled infielder Matt Mervis, right-hander Hayden Wesneski and left-hander Luke Little from Triple-A Iowa in corresponding moves. The 34-year-old Hendricks has been downright bad so far in 2024, posting a 12.00 ERA in his first five starts, but hopefully his back injury was mostly to blame. If left-hander Justin Steele (hamstring) is able to return from his IL stint before Hendricks does, which is likely, Hendricks could find himself out of a rotation spot when he's ready to return. With Hendricks out, Wesneski is a candidate to fill his rotation spot until Steele is able to return. Little will give the Cubs another left-handed arm out of the bullpen to replace Smyly.

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.

New York Yankees right-hander Gerrit Cole (elbow) got out to 120 feet on flat ground in his throwing program on Tuesday, which is typically as far out as pitchers will go before getting on the mound as they rehab. With that said, Cole isn't sure when he will advance to throwing off a mound. He will take the day off on Wednesday and go from there as he ramps up his throwing progression. If the 33-year-old reigning American League Cy Young winner feels good later this week, manager Aaron Boone said he could star throwing off a mound next week. Fantasy managers in all formats need to keep Cole stashed in an injured-list spot as he attempts to come back from nerve irritation in his right elbow, but he still has a ways to go.

Boston Red Sox outfielder Tyler O'Neill (concussion) was activated from the seven-day injured list on Tuesday and is serving as the designated hitter and batting third in the order against the Cleveland Guardians and right-hander Ben Lively. In a corresponding move, the Red Sox placed catcher Tyler Heineman (hamstring) on the 10-day injured list (retroactive to April 22) with a right-hamstring strain. O'Neill missed the minimum time on the IL after suffering a mild concussion during a collision with third baseman Rafael Devers last week. Fantasy managers should be ecstatic to get the 28-year-old outfielder back into their lineups, as he had a 1.21 OPS and seven home runs in his first 61 plate appearances before his head injury. O'Neill has never faced Lively in his career.

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 Kenta Maeda is set for his fifth start of the MLB season as the Detroit Tigers are on the road to play the Tampa Bay Rays on Tuesday. Maeda is coming off a terrible start against the Texas Rangers, as he went 2 2/3 innings and allowed six runs (five earned) on seven hits, including three home runs. Maeda is 0-1 with a 7.64 ERA and faces a Rays lineup is slashing .242/.304/.356. Fantasy managers would be wise to avoid Maeda in this one as a streamer.

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.

Arizona Diamondbacks third baseman Eugenio Suarez's plate vision was displayed in Monday's 5-3 loss against the St. Luis Cardinals. Suarez went 3-for-4 with two doubles, two RBI, and one run, finally connecting at the plate after going hitless in back-to-back games over the weekend against the Giants. He is 21-for-85 (.247) with five doubles, two homers, 16 RBI, 16 runs, eight walks and 24 strikeouts through 23 games. The season has had ups and downs for the third baseman and with his recent slump, the matchup against St. Luis favors him. With the favorable matchups for this week, Suarez is a strong stash option with upside across all formats.

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.

St. Louis Cardinals designated hitter Matt Carpenter (oblique) received a platelet-rich injection on Monday for his strained right oblique, according to manager Oliver Marmol. The plan is for Carpenter to have three days of no activity followed by hitting coach thrown batting practice and then machine work before they look at getting him live at-bats. The 38-year-old veteran had three hits in 10 at-bats over three games at the beginning of the season before getting hurt and landing on the injured list. When healthy, Carpenter will strictly be a bench bat and a DH option for the Cards when they are facing right-handed pitching. In 76 games with the San Diego Padres in 2023, he slashed a miserable .176/.322/.319 with five home runs and 31 RBI.

Washington Nationals outfielder Victor Robles (hamstring) will travel with the team as he continues to rehab a left-hamstring strain, which he suffered running from first to third base on April 3. Robles is throwing and hitting without pain and has regained full range of motion. Manager Dave Martinez hopes he will begin running drills soon. Robles had returned to full health during spring training after back spasms limited him to 36 games in 2023. It's good news that the 26-year-old is making progress, but when he's ready to rejoin the big-league roster, he's probably going to need to produce to continue playing regularly, especially given the fact that Washington has several big-name prospects that are itching to make their major-league debuts. Jacob Young has been serving as Washington's center fielder with Robles out and has gone 11-for-42 (.262) with no homers, two RBI and six steals in 15 games.

Atlanta Braves closer Raisel Iglesias converted his seventh save of the season in Monday's 3-0 win over the Marlins. Iglesias came in to pitch the top of the ninth inning up by three and delivered a 1-2-3 outing with a strikeout. The 34-year-old veteran has converted all of his save opportunities with a 2.16 ERA, a 6.48 K/9 rate, and a 1.08 BB/9 rate. The strikeouts have been down, but Iglesias should continue to be a higher-end fantasy option serving as the closer on one of baseball's best teams.

Atlanta Braves catcher Travis d'Arnaud continued his power surge in Monday's 3-0 win over the Marlins. d'Arnaud went 2-for-4 with a single, a two-run home run, and a strikeout. The 35-year-old veteran has hit five HR in his last four games, bringing his season numbers to a .273/.344/.636 slash line with 14 RBI in 61 plate appearances. d'Arnaud should be a viable fantasy option in at least two-catcher leagues as long as he continues to hit while Sean Murphy (oblique) is on the injured list with an oblique injury.

The Kansas City Royals placed right-hander Jordan Lyles (personal) on the inactive list on Saturday, and the team is not disclosing the reason for his absence other than describing it as a "personal matter." There's no timeline for his return, but because of the type of inactive list Lyles was placed on, it opened a 40-man roster spot for the Royals to call up veteran right-handed reliever Tyler Duffey. Lyles has thrown five scoreless innings with three strikeouts in five appearances out of KC's bullpen during the 2024 regular season, but he hasn't pitched since April 12. With no defined role and most of his work coming in mop-up duty this year, however, the 33-year-old journeyman belongs on fantasy waiver wires while he's unavailable. There's no clear-cut fantasy beneficiary of his absence, either.

Toronto Blue Jays first baseman Joey Votto (ankle) has started running more, but he's not hitting live pitching yet. There's no immediate plan for him to get into minor-league games, so until Votto resumes hitting, there's also no reason for fantasy managers to consider stashing the veteran on-base machine. After slashing .202/.314/.433 with 14 home runs and 38 RBI over 242 plate appearances (65 games) with the Cincinnati Reds a year ago, the 40-year-old former All-Star will be an option to serve as Toronto's designated hitter versus right-handed pitching when he's ultimately able to return from an ankle sprain and make his 2024 regular-season debut. Righty-mashing veteran Daniel Vogelbach will draw the occasional start as the DH, but he's only appeared in eight games for the Jays so far and isn't receiving enough at-bats to garner any fantasy interest right now.
