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.

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.

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.

Arizona Diamondbacks starting pitcher Merrill Kelly (shoulder) has been placed on the 15-day injured list on Tuesday. The right-hander is dealing with a shoulder strain, but reportedly won't need surgery, according to manager Torey Lovullo. The D-Backs have not given a timetable on Kelly's possible return to the mound. It sounds like the organization plans to have Kelly undergo further testing before they decide on what to do. Southpaw Tommy Henry has been recalled from the minors and figures to slide into the open spot in the starting rotation.

The Texas Rangers have signed starting pitcher Johnny Cueto to a minor-league contract on Tuesday. The 38-year-old lands a deal with the defending World Series champions after a rough year with the Miami Marlins. Cueto posted a 6.02 ERA, 1.26 WHIP, and a 39/15 K/BB ratio over 52 1/3 innings with the Marlins last season. It's uncertain what Cueto still has left in the tank, but he'll at least be additional depth for the organization. Cueto has plenty of experience but is unlikely to offer any kind of fantasy value.

Washington Nationals catcher Keibert Ruiz (illness) is scheduled to begin a minor-league rehab assignment with Double-A Harrisburg on Tuesday. Ruiz landed on the injured list last week with influenza. Barring any setbacks, Ruiz should be ready to return to the Nats lineup at some point later this week. Until then, Riley Adams and Drew Millas figure to split up the playing time behind the plate.

Philadelphia Phillies starting pitcher Taijuan Walker (shoulder) is set to make his season debut against the San Diego Padres on Sunday. The 31-year-old appears to be ready to pitch after missing time due to right shoulder soreness. Walker isn't an excellent fantasy option, but he could be worth a look in deeper mixed leagues. He has shown in the past that he has the skills to be a viable option in the big leagues. Fantasy managers who are in need of pitching help should keep an eye on Walker.

New York Yankees infielder DJ LeMahieu (foot) is scheduled to begin a minor-league rehab assignment with Double-A Somerset on Tuesday. It sounds like the plan is for LeMahieu to play four games in the minors before possibly returning to the Yankees roster. The veteran slugger has been sidelined all season due to a fractured foot. The Yankees could certainly use LeMahieu's help given their current struggles at the plate. Fantasy managers should wait patiently as it sounds like LeMahieu should be back soon.

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.

Chicago Cubs left-hander Justin Steele (hamstring) went through some fielding practice on Tuesday before the team's game against the visiting Houston Astros. Steele suffered his strained left hamstring while fielding a ball on Opening Day before landing on the injured list, so the Cubs want to make sure he's good before he throws in an extended spring training game this Friday. The 28-year-old will return to a spot in Chicago's rotation, but he's going to need at least a short minor-league rehab assignment before that happens. Steele is worth stashing in an injured-list spot in most fantasy leagues after going 16-5 with a career-best 3.06 ERA and 1.17 WHIP with 36 walks and a career-high 176 strikeouts in 173 1/3 innings in 30 starts for the Cubbies in 2023.

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.
