Minnesota Twins relief pitcher Caleb Thielbar earned his third save of the season in Monday's 3-1 win over the Mariners. Thielbar came in to pitch the top of the ninth inning up by two and delivered a 1-2-3 outing with two strikeouts. Closer Jhoan Duran was called upon to face the top of the order in the eighth inning, so Thielbar got the save opportunity. The 37-year-old veteran has gotten off to a rough start this season with a bloated 6.14 ERA in 7 1/3 innings pitched. His fantasy value will remain limited if he continues to pitch poorly, as it seems unlikely that he would earn high-leverage situations.

Minnesota Twins starting pitcher Simeon Woods Richardson turned in a quality start but came away with a no-decision in Monday's 3-1 win over the Mariners. The 23-year-old pitched six scoreless innings, allowing just one hit and one walk with eight strikeouts. Woods Richardson has capitalized on favorable matchups since being called up and is now 1-0 with a 1.74 ERA, a 9.15 K/9 rate, and a 2.18 BB/9 rate in four starts and 20 2/3 IP. His streak has a chance to continue in his next projected start at the struggling Blue Jays.

The Los Angeles Dodgers placed right-hander Joe Kelly (shoulder) on the 15-day injured list on Monday with a "right posterior shoulder strain." The move cleared a spot for right-hander Walker Buehler (elbow) to be activated from the IL. Kelly doesn't think the injury will keep him out for long, but that doesn't mean he will be ready to return once his stay on the 15-day IL is up. The 35-year-old reliever also dealt with a groin injury recently. The Dodgers' bullpen has taken a hit in recent days with both Kelly and closer Evan Phillips (hamstring) going on the shelf. With Phillips out, expect the Dodgers to move to a closer-by-committee, with players such as Daniel Hudson, Blake Treinen and Alex Vesia being candidates for save opportunities. Kelly has a 4.73 ERA and 1.35 WHIP with five walks and 14 K's in 13 1/3 relief innings so far in 2024.

The Baltimore Orioles announced on Monday that outfielder Austin Hays (calf) is scheduled to begin a minor-league rehab assignment with Double-A Bowie on Tuesday. Hays is working his way back from a left-calf strain that has sidelined him since April 20. Before his injury, the 28-year-old had already started losing playing time in Baltimore's outfield with rookie Colton Cowser impressing early on. But since then, Cowser's bat has cooled off, so it's possible that Hays will get another shot to make some noise for the O's when he's activated from the 10-day injured list, possibly as early as later this week. Unless Hays flips the script and sends Cowser to the bench, he'll mostly be a bench option in AL-only leagues. Before his injury, he had gone 5-for-45 (.111) with no homers and two RBI in 19 games.

Colorado Rockies outfielder Nolan Jones (back) did throwing and running drills on May 4 at PNC Park, a positive step in his recovery from a lower-back strain that landed him on the injured list last Tuesday. Jones dealt with back soreness last year as well and during spring training earlier this year. Manager Bud Black hasn't put a timetable on Jones' return but said that he is "progressing each day, which is encouraging -- we need him back to where he was last year." Barring setbacks, the 25-year-old left-handed slugger should be back starting for the Rockies by the middle of May. Jones hit .297/.389/.542 with 20 homers, 62 RBI and 20 stolen bases in 106 games for Colorado last year, so fantasy managers should stick with him despite his slow start in 2024.

Arizona Diamondbacks closer Paul Sewald (oblique) is on the brink of returning from the 15-day injured list after he said that his minor-league rehab outing in rookie ball on Saturday went as planned. He plans on traveling with the team to Cincinnati to begin a series with the Reds on Tuesday, and manager Torey Lovullo said it was a great sign that Sewald woke up without any pain after pitching in the Arizona Complex League. The 33-year-old said he got a couple of strikeouts and ground balls during his outing over the weekend. Sewald took a step back on his rehab assignment after feeling some soreness following an outing with Triple-A Reno on April 23, but he said he hasn't "felt anything in 10 days now." When Sewald returns to the team's bullpen, he'll be the primary closer, so fantasy managers should scoop him up right away if he was dropped when he landed on the injured list.

Arizona Diamondbacks left-hander Eduardo Rodriguez (shoulder) will have another MRI exam this week and could start his throwing program shortly after, according to manager Torey Lovullo. "He said he feels great and he's hoping for good news. And once we get that good news, he's going to be full steam ahead getting into a throwing program," Lovullo said. As long as the imaging shows significant healing and Rodriguez is asymptomatic, Lovullo expects a throwing program to begin quickly. The skipper said E-Rod told him he has been pain-free after he was initially shut down from throwing in mid-April due to left-shoulder tightness. It's good news for the 31-year-old veteran southpaw, but he won't be eligible to come off the 60-day injured list until late May and he's going to need a lengthy minor-league rehab assignment before he's able to rejoin Arizona's starting rotation.

Texas Rangers manager Bruce Bochy said that right-hander Nathan Eovaldi (groin) does not have a sports hernia, and the team thinks he'll be able to return soon around the time his 15-day injured list stint is up. Eovaldi visited with a specialist on Monday in New York, with Bochy calling it "good news." It was reported earlier on Monday that the 34-year-old veteran wouldn't need to go on a minor-league rehab assignment before returning from his IL stint, so all around it's been good news for Eovaldi's fantasy managers. As long as he doesn't suffer a setback when he returns to throwing, Eovaldi should be expected to return to Texas' starting rotation during the upcoming series against the Los Angeles Angels. Eovaldi needs to be stashed in all fantasy leagues while he's on the IL.

Cleveland Guardians third baseman Jose Ramirez belted his seventh home run of the 2024 regular season in Monday's 2-1 win over the division-rival Detroit Tigers, helping lift his team to victory. Ramirez's go-ahead blast came in the eighth inning, and it was his second homer in as many days after going yard in Sunday's series finale against the Los Angeles Angels. It's been a much-needed rebound for Ramirez, who was mired in a 3-for-28 dry spell over eight games prior to Sunday. The 31-year-old perennial All-Star is still slashing a disappointing .230/.278/.432 on the season, but he does have seven bombs, 28 RBI, 23 runs scored, and five stolen bases covering 139 at-bats (34 games) for the Guardians. Ramirez will try to solve his woes against the Tigers during the final two contests of this three-game series, as he's batting just .167 (9-for-54) with three round-trippers and six RBI across 14 games versus Detroit since 2023.

Miami Marlins third baseman Jake Burger (oblique) was reinstated from the 10-day injured list on Monday and is back at third base while hitting third in the series opener in Los Angeles against the Dodgers and right-hander Walker Buehler, who is making his first start in the big leagues since 2022. Burger is returning from a left-intercostal strain that caused him to miss the last few weeks. The 28-year-old right-handed slugger isn't going to help your fantasy team's batting average, but his power potential makes him worth rostering in at least deep-mixed leagues. In 57 at-bats before going on the injured list, Burger was hitting .228 (13-for-57) with three home runs, 15 RBI and eight runs scored. Burger hit a career-high 34 home runs in 141 games last year with the Marlins and White Sox.

Tampa Bay Rays left-hander Shane McClanahan (elbow) has ramped up to throwing from 90 feet. Manager Kevin Cash said on Friday that McClanahan is "progress well," although he's still in the early stages of his rehab from the second Tommy John procedure of his career. The 27-year-old southpaw is expected to miss the entire 2024 season. In a best-case scenario, it's possible that he'll return in the late stages this year, but fantasy managers in single-year formats shouldn't count on it at all. McClanahan was officially placed on the 60-day injured list on Feb. 14 before the team's first spring training workout. He underwent his second Tommy John surgery on Aug. 21 of 2023.

Tampa Ray Rays right-hander Drew Rasmussen (elbow) had a season-ending internal-brace procedure for a right-flexor strain on July 24 of last year. Rasmussen, who has previously had two Tommy John surgeries, is doing well in his rehab and is scheduled to throw in an extended spring game around May 20. President of baseball operations Erik Neander said before the season that Rasmussen could return to the big-league staff in the final months of the season. Rasmussen was put on the 60-day injured list back on Feb. 20. The 28-year-old should remain on the waiver wire in single-year fantasy leagues. The former sixth-round pick in 2018 by the Brewers out of Oregon State had a 2.84 ERA and 1.04 WHIP with a 125:31 K:BB in 28 starts covering 146 innings in his last full season in the majors in 2022.

Tampa Bay Rays left-hander Colin Poche (back) threw on flat ground at Tropicana Field on Sunday and was scheduled to throw a bullpen session on Monday. Poche went on the injured list on April 26 with mid-back tightness that had been preventing him from feeling fully comfortable on the mound. He received an injection in his back, which came before a few days of rest. The 30-year-old southpaw should be able to return in the middle of May as long as he doesn't have any setbacks. Poche won a career-high 12 games last year for the Rays and had a 2.23 ERA and 1.09 WHIP with a save. He has a 6.75 ERA and 1.61 WHIP in his first 9 1/3 relief innings so far in 2024, but he also has two saves and could be in the picture for saves, depending on when Pete Fairbanks (hand) is able to return.

Tampa Bay Rays infielder Jonathan Aranda (finger) is has not hit well during his minor-league rehab assignment with Triple-A Durham, and manager Kevin Cash said on Friday that the team wants to make sure Aranda is "timed up at the plate as much as possible" before ending his rehab assignment. Aranda fractured his right ring finger during a workout on March 19, which led to surgery to insert a pin into his finger on March 21. He had the pins removed from his finger on April 15. The 25-year-old looked great in spring training before his injury and should have a significant role for the Rays when he returns, at least as the designated hitter against right-handed pitching. Aranda is at least worth a pickup in deep-mixed leagues when he makes his 2024 debut.

Tampa Bay Rays right-hander Shane Baz (elbow) gave up three runs on three hits over three innings while walking one and striking out none in his first minor-league rehab assignment for Triple-A Durham on Saturday. Twenty-two of his 39 pitches went for strikes, and his four-seam fastball topped out at 97.1 mph. The 24-year-old missed all of last year after having Tommy John surgery. He was never expected to have a significant workload in 2024 after missing so much time, especially after he dealt with two minor oblique setbacks during his comeback. He essentially began his buildup after spring training ended and was put on the 15-day injured list on March 26. Baz will likely need several more rehab starts before Tampa thinks about activating him. Fantasy managers in single-year leagues need to temper their expectations for Baz in 2024 in his first season coming off Tommy John surgery.

Tampa Bay Rays outfielder Jose Siri is not in the team's starting lineup on Monday as they take on the visiting Chicago White Sox. Siri went 0-for-5 with two strikeouts in the last two games over the weekend to drop his season line to .176/.262/.286 in his first 91 at-bats of the year. The 28-year-old Dominican outfielder has added two home runs, seven RBI, six stolen bases and 11 runs scored in 31 games played. Siri hasn't played great defense either so far this year, so if he continues to struggle offensively, he could find himself on the bench more often now that Josh Low (oblique) is back from the injured list. Jonny DeLuca is starting in center field and is batting in the nine-hole for the Rays in the series opener against the White Sox and right-hander Mike Clevinger, who is making his season debut.

Los Angeles Angels infielder Luis Rengifo (illness) was scratched from Monday's lineup against the Pittsburgh Pirates. Rengifo missed the team's last two games on Saturday and Sunday against the Cleveland Guardians with an illness, but he's not sick anymore, and it's unclear why he was scratched from the series opener in Pittsburgh. Brandon Drury is now starting at third base and will hit sixth for the Halos against Pirates right-hander Mitch Keller. Rengifo has been hitting the ball well this year, going 30-for-91 (.330) with two homers, 11 RBI and nine stolen bases, so fantasy managers in deeper leagues will be hoping he's able to return soon. Drury, on the other hand, is hitting just .161 (15-for-93) with a homer and five RBI, but he's batting .600 in five career at-bats against Keller with a home run and six RBI.

Los Angeles Angels catcher Logan O'Hoppe (hand) is back behind the dish and is hitting fifth for the Angels on Monday against the Pittsburgh Pirates and right-hander Mitch Keller. O'Hoppe left the game on Saturday early against the Cleveland Guardians after taking a foul tip off his right hand, but X-rays came back negative and he will end up missing only one game as a result. Fantasy managers that have been rolling with the 24-year-old will want to get him back into their starting lineups this week. O'Hoppe will return to a .260/.317/.396 slash line with two home runs in his 29 games played so far in 2024. This will be the first time in his career that he's faced Keller.

Cleveland Guardians outfielder Steven Kwan (hamstring) is expected to miss four weeks with an acute hamstring strain, according to Mandy Bell of MLB.com. Kwan left Saturday's 7-1 win over the Los Angeles Angels with hamstring tightness in the top of the fourth inning. However, an MRI revealed a strain for the outfielder, which will cause him to be out for approximately one month. The 26-year-old has been one of the best hitters this season, batting .353 with three home runs, 11 RBI, six doubles, and two triples in 32 games. Fantasy managers should place him in one of their injured list spots and expect a return sometime at the beginning of June.

The Cincinnati Reds optioned left-handed pitcher Sam Moll to Triple-A Louisville on Monday. Moll has been great out of the bullpen for the Reds in 2024, allowing zero earned runs across five inningssince making his season debut in late April. However, with Cincinnati needing a roster spot to officially activate Frankie Montas (forearm) for Tuesday's start, the southpaw is the odd man out. The left-hander has a career 3.31 ERA and 133 strikeouts in 147 appearances in his MLB career.
