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.

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.

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.

Chicago White Sox left-hander Martin Perez (elbow), who was moved to the 60-day injured list on Monday, will not have Tommy John surgery, a source told ESPN's Jess Rogers. Perez could resume throwing again in September, but he will not make it back to the big leagues in 2025. With the 34-year-old southpaw potentially also not being ready for the start of next season, the White Sox will surely decline their $10 million mutual option for the 2026 season in time. The Venezuelan hurler should have only been rostered in AL-only fantasy leagues before his injury. In his four starts for the Pale Hose before suffering a season-ending left-elbow injury, Perez was pitching well, posting a 3.15 ERA (3.69 FIP) and 1.25 WHIP with 18 strikeouts and 11 walks in 20 innings pitched. He can officially be dropped in AL-only formats.

San Francisco Giants first baseman/designated hitter Wilmer Flores went 2-for-3 with a walk and a home run in the Giants' 5-2 win over the visiting Brewers on Monday night. Flores' solo shot in the sixth inning snapped a 2-2 tie and gave the Giants the lead they would hold to the end of the game. The big blast was not only pivotal in securing the win, it also continued a great start to the season for Flores, who now has seven homers in just 23 games after managing just four long-balls in 71 games last year. The 33-year-old is hitting .220 with a .325 wOBA on the year and has been especially effective at Oracle Park, where he has a .360 home batting average and .428 home wOBA on the season. He's worth look if you need power in NL-only leagues or are looking for a short-term fill-in at 1B.

San Francisco Giants starting pitcher Robbie Ray gave up a two-run home run to rookie Caleb Durbinbut was able to limit the damage to just those two runs allowed over his five innings on Tuesday night. He was not efficient with his pitch count and needed 92 pitches to get through five frames while striking out four, walking three, and giving up five hits. The 33-year-old lefty has issued at least three free passes in each of his last four starts and has a 6.7 BB/9 rate on the year. He'll need to improve his control and efficiency to work deeper into games, but he has battled to maintain a 9.3 K/9 and 4.07 ERA despite a 5.87 FIP and 1.56 WHIP. The Giants ultimately won Monday's game, and they'll hope to get a better outing from Ray in his next scheduled start on Saturday against the Rangers.

Cleveland Guardians third baseman Jose Ramirez had a big game in a 6-4 win over the New York Yankees on Monday. Ramirez went 2-for-5 with a homer and four RBI to help power his team to the win. The star infielder hit a three-run homer off New York starter Clarke Schmidt in the third inning to break a scoreless tie and then came back to add an RBI single in the sixth inning. Ramirez is now hitting .276 with five homers, 10 runs, 13 RBI, and three steals across 76 at-bats in 2025. He is starting to heat up at the plate with a .357 average over his past seven games. He remains a must-start fantasy option in all formats.

The Seattle Mariners have decided to trade left-handed relief pitcher Drew Pomeranz to the Chicago Cubs on Monday. The veteran southpaw reportedly has an upward-mobility clause in his contract. That means that the Mariners needed to offer Pomeranz to every team, and if there was an organization willing to promote him, then he needed to be traded there or recalled to Seattle's bullpen. He'll be sent to Chicago after posting a 4.66 ERA with 14 strikeouts and six walks in 9 2/3 innings in Triple-A. Pomeranz hasn't pitched in the MLB since 2021, so it's unclear what exactly the Cubs are going to get here.

Houston Astros first baseman Christian Walker is taking the day off for Monday's series opener against the visiting Toronto Blue Jays at Daikin Park. Zach Dezenzo is starting at first base and is batting ninth against Blue Jays right-hander Kevin Gausman. Although he did go deep over the weekend against the San Diego Padres, Walker could use a mental rest after going 3-for-26 in his last eight games. The 34-year-old veteran power hitter hasn't gotten off to the start he was hoping for in his first year in Houston, as he's currently slashing .156/.253/.260 with two home runs, four RBI and nine runs scored in 77 at-bats. Walker has provided consistent power numbers in recent seasons, so fantasy managers are expecting him to turn things around sooner than later. Dezenzo has never faced Gausman in his MLB career and will be a weak DFS target for Monday's action.

Los Angeles Dodgers right-handed pitcher Blake Treinen (forearm) is dealing with a low-grade sprain and will begin a "conservative" rehab. The reliever will not have to undergo surgery. This is an excellent sign as Treinen was placed on the 15-day injured list with a forearm injury on Saturday. However, it appears the 36-year-old has avoided a significant injury. Fantasy managers should continue to monitor his progression as he slowly increases his workload. Through the early part of the campaign, the right-hander has held a 3.38 ERA with a 1.38 WHIP across eight innings of work. He has struck out 10 batters, tallied three holds, and earned two saves. He has generated a strong 3.47 xERA with a stellar 31.8 percent hard-hit rate. While the right-hander remains out, Tanner Scott should see the bulk of the save opportunities with Kirby Yates and Alex Vesia mixing in.

Arizona Diamondbacks third baseman Eugenio Suarez is not in Sunday's lineup when they conclude a series against the Chicago Cubs. Suarez has started in each of the first 21 games of the regular season. During this stretch, the power-hitting third baseman has held a .145/.253/.421 slash line with three doubles and six home runs. He enjoyed an impressive start, holding a .250/.379/.919 line with five long balls across the first seven games. Over his last 14 games, he has posted a rough .096 AVG. Fantasy managers should expect the 33-year-old to return to the starting nine on Tuesday, when they host the Tampa Bay Rays. As a result, Garrett Hampson will cover the hot corner on Sunday afternoon and bat in the nine-hole.

Philadelphia Phillies catcher J.T. Realmuto will get the day off on Sunday when the Phillies conclude a series against the Miami Marlins. Realmuto has started in each of the previous eight games. During this stretch, he has held a .200/.273/.333 slash line with one double and one home run. Fantasy managers should expect the veteran backstop to return to the starting nine on Monday evening when the Phillies begin a series in Queens against the Mets. Through 18 games this season, the 34-year-old has held a .234/.315/.338 slash line with four runs and six RBI. Instead, Rafael Marchan will be behind the dish and catching for Jesus Luzardo. He will bat ninth and should not be targeted in any DFS competitions.

Minnesota Twins catcher Christian Vazquez (hand) is rejoining the starting nine on Saturday afternoon when the Twins continue a series against the Atlanta Braves. The veteran catcher has been kept sidelined through most of the week since suffering this injury on Monday. However, Vazquez was able to avoid a stint on the injured list. He will catch for Minnesota right-hander Simeon Woods Richardson and bat in the eight-hole. Through his first 11 games of the regular season, Vazquez has posted an underwhelming .115/.172/.192 slash line with two doubles. He has yet to go deep. Despite his poor production at the plate, Vazquez has posted a stellar 16.7 percent whiff rate and a 17.2 percent strikeout rate. Vazquez is not worth targeting in DFS this afternoon, facing Atlanta southpaw Chris Sale.

The Chicago White Sox have placed left-handed pitcher Martin Perez (elbow) on the 15-day injured list due to left elbow inflammation. The 34-year-old exited Friday's contest due to soreness and will now miss at least the next two weeks of action. Before exiting, the southpaw struggled against the Boston Red Sox as he allowed five hits, four runs, and two walks in just three innings of work. However, over his first three starts of the campaign, Perez looked quite sharp as he tossed 17 innings to the tune of an impressive 1.59 ERA and a 1.06 WHIP. He struck out 18 batters and served up nine free passes. In a corresponding move, the White Sox promoted Jared Shuster from Triple-A Charlotte to provide depth on their pitching staff. Shuster could contend for starting opportunities while Perez is sidelined.

Boston Red Sox relief pitcher Liam Hendriks (elbow) is expected to be activated off the 15-day injured list prior to Saturday's contest against the Chicago White Sox. Chris Cotillo of MassLive.com noted that Hunter Dobbins is likely heading back to Triple-A in a corresponding move. Hendriks signed a two-year deal with the Red Sox before the 2024 campaign but has yet to make an appearance for them. He underwent Tommy John in 2023 and then hit the 15-day IL at the start of the 2205 campaign due to elbow inflammation. He has made three rehab appearances and fired three shutout frames. He has struck out five batters, served up two walks, and has allowed just one hit. Even though Aroldis Chapman and Justin Slaten have been the go-to options in the ninth inning, fantasy managers should expect Hendriks to see save situations throughout the campaign.

Chicago White Sox starting pitcher Martin Perez (forearm) is set to undergo an MRI on Saturday. The southpaw was lifted from Saturday's contest in the third inning after feeling soreness in his forearm. Before exiting the contest, Perez allowed five hits, two walks, and four earned runs. Despite his struggles on Friday, Perez was enjoying an impressive start to the young season. In his first three outings, the left-hander tossed 17 innings to the tune of a 1.59 ERA and an impressive 1.06 WHIP. He struck out 18 batters and served up nine walks. However, he already began to see some regression on Friday as he has generated a hefty 6.54 xERA and a .293 xBA. If the 34-year-old were to miss time, fantasy managers should expect the White Sox to promote a pitcher from Triple-A to fill his spot in the rotation.

Chicago White Sox starting pitcher Martin Perez (forearm) was forced to exit early during Friday's game against the Boston Red Sox. The southpaw didn't have favorable results before exiting the contest. Perez allowed five hits, four earned runs, and two walks in three innings of work. He was pulled from the game due to left forearm tightness. The expectation is that Perez will undergo further imaging to determine the severity of the issue. For now, Perez can be considered day-to-day, but could end up on the injured list. Fantasy managers can hold Perez for now who has been solid with two earned runs or less in all of his starts prior to Friday's game.

Arizona Diamondbacks' third baseman Eugenio Suarez hit a grand slam on Friday afternoon in the DBack's 13-11 loss to the Chicago Cubs. The grand slam was his sixth home run on the season and he's now hitting for a .709 OPS. The HR was much needed for the 33-year-old, who hadn't hit one in over two weeks. Fantasy managers will be glad to see the power is still there but his .153 batting average may make them feel like his production is either boom or bust, making him tougher to trust if he doesn't become more consistent. He'll look to keep improving on Saturday against scheduled Cubs' starter Ben Brown.

Detroit Tigers right-hander Tommy Kahnle picked up the save in a 6-1 win over the Kansas City Royals on Thursday. Kahnle tossed two scoreless innings while not allowing a baserunner and failing to record a strikeout to preserve the win. The veteran reliever has been productive at the back of the Detroit bullpen this season, converting all three of his save chances while posting a 1.29 ERA, 0.43 WHIP, and five strikeouts over seven innings of work. The Tigers opened the season with a ninth-inning committee, but it appears that Kahnle has emerged as the favorite for the ninth-inning role moving forward.
