Boston Red Sox starting pitcher Tanner Houck continued his strong start to the season in Monday's 4-1 loss to the Guardians. Houck pitched six innings, allowing two runs on five hits and three walks with four strikeouts. The 27-year-old has been excellent to start the season, going 3-2 with a 1.65 ERA, an 8.82 K/9 rate, and a 1.38 BB/9 rate in his first five starts. His next start will be a middling matchup against the Cubs, but he has pitched well enough to earn the nod in most matchups at this time.

Cleveland Guardians closer Emmanuel Clase picked up his seventh save of the season in Tuesday's 4-1 win over the Red Sox. Clase came in to pitch the top of the ninth inning up by three and shut things down by striking out the side. The 26-year-old has looked more like his old self this season, converting all but two save opportunities with a 0.75 ERA, a 9.75 K/9 rate, and a 0.75 BB/9 rate. Clase was still a high-end fantasy option in 2023 with slightly less impressive numbers overall, so he can be even more valuable if he reverts to how he performed early in his career.

Atlanta Braves starting pitcher Max Fried looked like his old self in Tuesday's 5-0 win over the Marlins. Fried made the most of a favorable matchup, pitching a complete-game shutout with three hits, no walks, and six strikeouts on just 92 pitches. It was a great outing for the 30-year-old, who has struggled out of the gate this season. He is now 2-0 with a 4.97 ERA in his first five starts. He will look to build on his success in his next projected start, which will be at a middling Mariners lineup.

San Diego Padres starting pitcher Michael King did not last long in Tuesday's 7-4 loss to the Rockies. King pitched just 3 2/3 innings, allowing six runs (four earned) on eight hits (including a grand slam) and three walks with five strikeouts. The 38-year-old has had an up-and-down start to the season with his new team, going 2-2 with a 4.11 ERA, a 9.98 K/9 rate, and a 5.28 BB/9 rate in five starts. He will look to rebound in his next start in a tougher matchup against the Phillies.

Colorado Rockies relief pitcher Justin Lawrence picked up his first save of the season in Tuesday's 6-4 win over the Padres. Lawrence came in to pitch the top of the ninth inning up by three. He got the first two outs on a lineout and groundout, allowed a single, and ended the game on a flyout. Lawrence has pitched poorly overall this season with a 6.23 ERA and a 4.15 K/9 rate in nine appearances. The Rockies may not see many save opportunities this season, as this was just their fourth. However, Jake Bird has seen two of them and has pitched better than Lawrence, so he may be the best fantasy option right now in deeper roto leagues.

Colorado Rockies outfielder Nolan Jones (back) exited Tuesday's 7-4 win over the Padres early with a stiff back, per MLB.com's Thomas Harding. The 25-year-old went 1-for-4 with a single, an RBI, and a strikeout before being replaced by Jake Cave. Fantasy managers should keep an eye out for further updates, but Jones can be considered day-to-day for now. He has been highly disappointing to start the season, slashing just .148/.219/.250 in 96 plate appearances.

Arizona Diamondbacks manager Torey Lovullo said Tuesday that the team could be without starting pitcher Merrill Kelly (shoulder) for at least a month. Kelly was placed on the injured list earlier in the day with a right shoulder strain. When asked if the 35-year-old would be back by the All-Star break, Lovullo said, "I don't know. Hard to say." This is a big blow to the Diamondbacks and fantasy managers, as Kelly had a 2.19 ERA, 0.93 WHIP, and 22.8% strikeout rate in his first four starts. Tommy Henry figures to slot into the rotation in Kelly's place, but fantasy managers may want to look elsewhere for immediate replacements.

Texas Rangers starting pitcher Jon Gray made a surprise relief appearance in Saturday's loss to the Atlanta Braves, but he's scheduled to take the ball as a starter for Wednesday's game at home versus the division-rival Seattle Mariners. After yielding five runs in his first start of the 2024 regular season, Gray is getting on a roll in April with a 1.10 ERA (2.47 FIP) and 23:7 K:BB over his last 16 1/3 innings (four appearances). The 32-year-old veteran right-hander dominated Seattle a season ago, logging a pristine 0.64 ERA, 0.50 WHIP, and 13:1 K:BB across 14 frames (two starts) against the division foes in 2023. The current M's roster is batting a paltry .159 (14-for-88) against Gray, who looks like a solid streaming option and a worthy pickup during Tuesday night's waiver runs in fantasy ahead of Wednesday's full slate.

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.

Chicago Cubs outfielder Cody Bellinger exited Tuesday's game versus the Houston Astros with an apparent injury after crashing into the wall in center field. Bellinger hit the wall hard tracking down a Yainer Diaz double in the fourth inning, and the center fielder was later seen holding his right side in the dugout. Bellinger remained in the game all the way up until the seventh frame before he was removed for Alexander Canario, so his departure could very well be a precautionary measure. The Cubs should provide a clearer picture on the 28-year-old All-Star slugger's health following the contest, and he should be deemed day-to-day ahead of the second game of the series on Wednesday. After clubbing a two-run home run on Tuesday, Bellinger is up to a .226/.320/.440 triple-slash line with five homers, 17 RBI, and 10 runs scored in 84 at-bats (22 games).

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.

Tampa Bay Rays manager Kevin Cash said that closer Pete Fairbanks (undisclosed) underwent tests on Tuesday that came back "really clean". Fairbanks was sent for multiple tests, evaluating everything from his neck to his fingertips, but the Rays still haven't provided a specific diagnosis. Cash is "encouraged that nothing is showing up", though. While it's promising to hear no serious setback for Fairbanks has come to light to this point, the hard-throwing 30-year-old right-hander's return timetable from a nerve-related issue remains very cloudy. Over Fairbanks' two injured-list stints last season, setup man Jason Adam collected 10 saves while the closer was sidelined and belongs on all mixed-league fantasy rosters until Tampa Bay's bullpen hierarchy becomes clearer. Lefty Colin Poche should be in the mix for ninth-inning work as well, but he gave up three runs in the eighth inning in Tuesday's 4-2 loss to the Detroit Tigers.

Washington Nationals outfielder Lane Thomas (leg) exited Tuesday's game versus the Los Angeles Dodgers with an apparent left leg injury. Thomas appeared to twist his left leg on a slide while attempting a stolen base in the fifth inning and was able to stay in the game temporarily, but he was later replaced by Eddie Rosario in right field in the seventh. Considering Thomas was able keep playing for a bit, there's optimism that he's only dealing with a minor injury. Expect the Nats to offer some clarity on his status following the contest, and Thomas should be deemed day-to-day ahead of the second game of the series with LA on Wednesday. The 28-year-old right fielder is batting a mere .184 (16-for-87) with two home runs and 10 RBI in 22 games this season, but his 11 swipes are softening the blow. It wouldn't hurt fantasy managers in deep leagues to make a speculative add on No. 2 prospect James Wood until Thomas is fully healthy.

The New York Yankees have announced that third baseman DJ LeMahieu (foot) left Tuesday's minor-league game with Double-A Somerset due to soreness in his right foot, and the infielder will return to New York for examination tomorrow. The Yankees' plan was for LeMahieu to make four rehab appearances before potentially being activated from the injured list on Sunday, but this development is likely to delay the veteran's 2024 regular-season debut a bit longer. LeMahieu is working his way back from a non-displaced fracture of his right foot that he sustained on March 16, and the severity of his setback should be revealed sometime in the coming days. Switch-hitting utility man Oswaldo Cabrera is batting .290 (20-for-69) with three home runs, 14 RBI, and 11 runs scored in 19 games this year, and he should continue manning the hot corner regularly until LeMahieu is finally ready to play.

Los Angeles Dodgers outfielder Jason Heyward (back) isn't swinging a bat and is still dealing with "residual soreness," according to manager Dave Roberts. Heyward is still more than a week from starting a minor-league rehab assignment. The 34-year-old veteran left-handed hitter was put on the 10-day injured list all the way back on April 3 with back soreness, and he hasn't made much progress since. There remains no timetable for a return from the IL, but fantasy managers in deeper leagues should expect him to be out at least another few weeks. Outfielder Teoscar Hernandez has been shifted over to right field for the Dodgers with Heyward out, while rookie prospect Andy Pages has also been platooning in center field with James Outman.

Miami Marlins left-hander Braxton Garrett (shoulder) threw a 25-pitch side session on Tuesday that went "great," according to the team. He will now through four innings or 60 pitches in a minor-league rehab start for Triple-A Jacksonville on Friday. Garrett had to pause his rehab assignment after dealing with dead arm, but he's back up and running and may need only a few rehab starts before he's activated to rejoin Miami's starting rotation in the big leagues. The former seventh overall pick by the Fish in 2016 out of high school is worth picking up and stashing right now in deep-mixed fantasy leagues. Garrett flashed his upside in a career-high 31 outings (30 starts) last year when he went 9-7 with a 3.66 ERA and 1.15 WHIP with 29 walks and 156 strikeouts in 159 2/3 innings.

Colorado Rockies outfielder Kris Bryant (back) is eligible to come off the 10-day injured list for a lower-back strain on Wednesday, but that won't be happening. Manager Bud Black said that Bryant isn't doing any baseball activities yet. Bryant hasn't undergone anymore tests, though, and there has been no discussion of surgery. Given all the time the 32-year-old former MVP has missed in recent seasons due to various ailments, it makes sense for the Rockies to bring him back slowly, even if his back injury isn't considered very serious. Fantasy managers in deeper leagues must remain patient, but in shallower leagues, it's fair to consider dumping him for better options after he started the year going 7-for-47 (.149) with a home run and six RBI.

Houston Astros left-hander Framber Valdez (elbow) will throw a bullpen session with the team in Chicago this week and he could start one of the two games against the Colorado Rockies in Mexico City, either this Saturday or Sunday, according to manager Joe Espada. The 30-year-old southpaw was able to throw a 30-pitch bullpen session last Saturday, which was his first time throwing off a mound since left-elbow inflammation landed him on the injured list on April 9. Whether Valdez is able to make his return and start this weekend against the Rockies will be determined by how he looks in his next bullpen session this week. Even though the Rockies are a very enticing matchup, Valdez would be a shaky fantasy play in the altitude in Mexico City if he's activated for a start this weekend.

Los Angeles Angels right-handed reliever Robert Stephenson (elbow) said he will have Tommy John surgery with the internal brace on April 30 and he's expecting to have a rehab timeline of 12 to 18 months. The exact nature of his surgery hadn't been revealed until Stephenson talked to the media on Tuesday for the first time since getting injured. We already knew the 31-year-old veteran would miss the rest of 2024, but now we know the exact nature of his surgery. He signed a three-year, $33 million contract with the Halos in January but didn't throw a single pitch in the regular season and also was battling a shoulder injury in spring training. There's no guarantee that Stephenson will be ready to roll for the start of the 2025 campaign.

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.
