St. Louis Cardinals right-handed pitching prospect Tekoah Roby has been promoted from Double-A Springfield to Triple-A Memphis. Roby, the team's No. 11 prospect per MLB Pipeline, gets the promotion after going 4-2 with a 2.49 ERA, 0.96 WHIP and 57:11 K:BB in 47 innings over 10 starts. The 23-year-old former third-rounder by the Texas Rangers in 2020 only managed 10 total starts last year due a shoulder injury, so it's nice to see him bounce back already in 2025. Roby, who stands at 6-foot-1 and 210 pounds, could make his major-league debut later this season if he impresses at Memphis. He features a fastball, nasty curveball, slider and changeup. It's nice to see him performing well this season, but the Cardinals will likely want to see him get through a whole year healthy before considering him for their rotation in 2026.

The St. Louis Post-Dispatch's Daniel Guerrero writes that St. Louis Cardinals right-handed pitching prospect Michael McGreevy could come back up to the big leagues to make another spot start later this month. McGreevy came up to make his first start of the year on Sunday against the Los Angeles Dodgers and took the loss after allowing four earned runs on eight hits while walking none and striking out five in six innings. All things considered, it wasn't a bad showing for the 24-year-old, who is considered the team's No. 10 prospect per MLB Pipeline. The former 18th overall pick in 2021 out of Santa Barbara has held his own with a 3.09 ERA and 0.86 WHIP with 10 strikeouts in his two outings (11 2/3 innings) this year after making his MLB debut in 2024. McGreevy's stuff isn't anything special, but he's a ground-ball artist with exceptional control.

St. Louis Post-Dispatch's Derrick Goold writes that St. Louis Cardinals closer Ryan Helsley (toe) dealt with a toe injury on his right foot earlier this year that required him to wear an insert in his cleat that led to a drop in velocity and a lack of command. The 30-year-old right-hander first dealt with the injury in spring training, although he said he feels great now. It's worth noting after he blew his third straight save in Monday's loss to the Toronto Blue Jays. In his three outings in June, Helsley has allowed a run each time out on six total hits (one homer) while walking one and striking out five in three innings. The two-time All-Star currently sports a 3.75 ERA and 3.99 FIP with a 1.54 WHIP and 13 saves in 24 innings in 2025 after leading the league with 49 sacks in 2024. The good news is Helsley's velocity is back up, and he's confident he can bounce back after a rough start to the month.

St. Louis Cardinals outfielder Lars Nootbaar is out of the team's starting lineup for Tuesday's contest against the visiting Toronto Blue Jays at Busch Stadium. Brendan Donovan will start in left field and bat third, while Nolan Gorman starts at second base and bats out of the seven-hole against Blue Jays right-hander Chris Bassitt. Nootbaar will get a day off after starting in each of the team's last 16 contests. It's a good time for a break, as the 27-year-old outfielder has just one hit in his last 19 at-bats to drop his season line to .237/.341/.379 in 253 at-bats. Both Donovan and Gorman have found some success against Bassitt in the past, albeit in small sample sizes. Donovan has hit .429 with a homer and two RBI in seven at-bats, while Gorman has homered twice and driven in four in his two at-bats versus Bassitt. Donovan currently ranks 11th in MLB with his .314 average on the year.

The New York Mets announced on Tuesday that they placed catcher Francisco Alvarez on the paternity list and recalled catcher Hayden Senger from Triple-A Syracuse in a corresponding move. Alvarez will be away from the team for a few days and probably won't return until sometime this weekend for a series at home against the Tampa Bay Rays. With Alvarez out, veteran Luis Torrens will do the catching and hit sixth on Tuesday against the division-rival Washington Nationals and tough left-hander MacKenzie Gore. Senger will serve as New York's backup for a few days. Alvarez got a late start to the 2025 season due to injury and is currently hitting .255 (26-for-102) but with only two home runs, 10 RBI and six runs scored in 114 trips to the plate. Injuries also slowed him down last year, but the 23-year-old hit 25 homers in his first full MLB season in 2023.

Boston Red Sox designated hitter Rafael Devers (undisclosed) slowed down before getting to first base in the series finale against the New York Yankees on Sunday and was seen grimacing during the play. "He plays every day; obviously he's a DH, and there's certain thingsnothing majorbut stuff that we have to pay attention to," manager Alex Cora said. In his following at-bat on Sunday, Devers hit a 393-foot home run in the ninth inning, so the injury obviously isn't too serious. However, it's something to keep an eye on, and it could cause Cora to give the 28-year-old a rest day coming up. Devers told Cora that he was "doing OK." He has played in all 68 games in 2025, so it's probably time for his first day off of the season. The Dominican infielder has been solid in his full-time move to DH this year and is slashing .280/.409/.516 with a .925 OPS, 14 homers, 57 RBI and 45 runs scored.

SI.com's Jack Sommers reported on Monday that Arizona Diamondbacks outfielder Corbin Carroll (hamstring) has been battling through a tight hamstring. Carroll was still in the lineup for Monday's series-opening, extra-inning win over the visiting Seattle Mariners, though, and went 1-for-5 with a solo home run and a walk. The 24-year-old former National League Rookie of the Year missed a couple games over the weekend, and now we know why. He should be fine, but it's something to keep an eye on moving forward if he misses anymore games. If anything, it could cause the former first-rounder to run less on the basepaths. When Carroll is in the starting lineup, he's a must-start in all fantasy leagues with a .258/.339/.569 slash line, .908 OPS, 19 home runs, 41 RBI, 50 runs scored and 10 stolen bases in 260 at-bats this year.

The San Francisco Giants placed third baseman Matt Chapman (hand) on the 10-day injured list on Tuesday with right-hand inflammation and recalled infielder Christian Koss in a corresponding move, according to the San Francisco Chronicle's Shayna Rubin. X-rays came back negative on Chapman's hand after he injured it during a slide on Sunday against the Atlanta Braves, but he'll be forced to miss at least the next 10 days. Hopefully, the 32-year-old veteran will be able to return when he's eligible to come off the IL on June 19. In his second season with San Fran, Chapman has hit .243 (56-for-230) with 12 home runs, 30 RBI, 35 runs scored and seven steals in 65 games played. Casey Schmitt is likely to see most of the playing time at third in Chapman's absence, but he's merely a waiver-wire candidate in NL-only formats. San Fran's defense and offense will take a hit without one of their best players.

Tampa Bay Rays pitching prospect Ian Seymour made his MLB Debut on Monday, coming on in the 10th inning of the team's 10-8 win over the Red Sox in extras. The lefty allowed one unearned run on an error by first baseman Jonathan Aranda, while walking two (one intentional) and striking out two in the two-inning outing. He did not allow a hit in nine batters faced, and because the Rays would take the lead in the top of the 11th and go on to be victorious with Seymour on the mound, the Rays' 19th-ranked prospect would end up as the winning pitcher in the contest. The 26-year-old could be a ratio-enhancer if he ends up sticking around, especially with his strikeout ability, but offers little more fantasy relevance without a closing role.

The Baltimore Orioles announced on Tuesday that they optioned outfielder Heston Kjerstad to Triple-A Norfolk and reinstated outfielder Cedric Mullins (hamstring) from the 10-day injured list in a corresponding move. Kjerstad gets caught in a roster crunch with Baltimore's outfield getting healthy. The 26-year-old former second overall pick in 2020 out of Arkansas has not been able to carve out a regular role with the team since debuting in 2023. In 54 games this year, he went 30-for-156 (.192) with four home runs, five doubles, two triples, 19 RBI, 16 runs scored, a steal, six walks and 45 strikeouts in 167 plate appearances. Kjerstad has a .218/.284/.365 slash line, .649 OPS, 10 homers, 36 RBI and 88 strikeouts in 106 games played at the big-league level since 2023. He has hit the ball hard, but he's just not making enough contact.

The Baltimore Orioles announced on Tuesday that they reinstated outfielder Cedric Mullins (hamstring) from the 10-day injured list and optioned outfielder Heston Kjerstad to Triple-A Norfolk in a corresponding move. The Orioles haven't released their lineup for Tuesday's tilt against the visiting Detroit Tigers, but Mullins may be on the bench with left-hander Brant Hurter on the mound. Mullins skipped a minor-league rehab assignment after straining his right hamstring in late May. His return will push Jorge Mateo back to a reserve infield role with Colton Cowser shifting to a corner outfield spot now against right-handed pitchers. Mullins has a .232 batting average on the year but also sports a .218 xBA, so he's not going to help fantasy managers at all in the average department. The 30-year-old does already have 10 homers and eight steals through 50 games, though.

The Baltimore Orioles announced on Tuesday that they reinstated infielder Jordan Westburg (hamstring) from the 10-day injured list and designated infielder Emmanuel Rivera for assignment in a corresponding move. The Orioles haven't released their lineup for Tuesday's game against the visiting Detroit Tigers, but Westburg figures to be back in there against left-hander Brant Hurter. The 26-year-old has been out since late April with a strained left hamstring, but he should be the club's starting third baseman now that he's back. In his eight minor-league rehab games with Norfolk, he went 11-for-28 with two home runs. Fantasy managers will be hoping he can carry that over after a slow start with the bat before his injury. The former first-rounder went 20-for-92 (.217) with four homers and six RBI in his first 23 games. Westburg was an All-Star in 2023 and hit 18 bombs in 107 games played.

ESPN's Jeff Passan reports that the Milwaukee Brewers are calling up right-hander Jacob Misiorowski, one of the best pitching prospects in baseball, on Tuesday, according to sources. Misiorowski is ranked as the 30th overall prospect in the game by ESPN's Kiley McDaniels and has a fastball that has reached 103 mph this year. He's expected to start on Thursday against the division-rival St. Louis Cardinals in his MLB debut. MLB Pipeline considers the 23-year-old to be Milwaukee's No. 4 prospect. Although Misioriwowski's control has been an issue in the past, it's been better this year and he's posted a 2.13 ERA and 1.09 WHIP with 80 strikeouts and 31 walks in 63 1/3 innings over his 13 outings (12 starts) for Nashville. A learning curve is expected, but Misiorowski should be an immediate waiver-wire priority, and he could stick around in Milwaukee's rotation for the rest of the year.

Chicago Cubs outfielder Kyle Tucker went 1-for-3 with a solo home run in his team's 4-3 road loss to the Philadelphia Phillies. The 28-year-old added two walks and scored twice. Tucker got the Cubs on the board in the top of the first with a solo shot off Phillies starter Zack Wheeler, though they wouldn't score again until the eighth. It was his thirteenth long ball of the season. He notched his second run of the matchup in the eleventh when teammate Pete Crow-Armstrong doubled him home. Tucker has slowed down some in June, going just 5-for-21 (.238), but it was nice to see him go yard for the first time since jamming his finger last week. Despite the slight slump, four of his five hits in the month have gone for extra bases.

Miami Marlins second baseman Otto Lopez went 1-for-1 with a solo home run in Monday's 10-3 loss to the Pittsburgh Pirates. He also drew two free passes. The Dominican Republic native belted his sixth long ball of the season in his first at-bat, giving the Marlins a 1-0 lead in the top of the second inning. However, it'd be the last time they sat atop the scoreboard in Monday's lopsided defeat. Lopez is riding a four-game hit streak, notching two homers and two steals in that span. Despite an unappealing .233/.311/.375 triple slash, the 26-year-old is underproducing quite a bit. In addition to an average nearly 50 points lower than his .282 xBA, Lopez's .482 xSLG is a much more palatable figure than the one he holds. His career-low .243 BABIP figures to rise in short order.

Atlanta Braves first baseman Matt Olson went 1-for-3 with a two-run home run in his team's 7-1 win against the Milwaukee Brewers. The veteran also walked twice. Olson knocked in teammate Austin Riley to culminate a three-run fifth inning with a 417-foot blast to dead-center. It came off Brewers' reliever DL Hall's first pitch of the outing, and was dinger No. 14 on the season for him. The 31-year-old is sporting one of his lowest averages against righties in 2025 (.227). However, he's underperforming his .269 xBA by over 30 points (.238). Furthermore, Olson holds the best quality of contact metrics of his career -- boasting personal-bests in average exit velo (94.2 MPH) and hard-hit rate (56.3%).

From RotoBaller

Atlanta Braves outfielder Ronald Acuna Jr. went 1-for-3 with a solo home run in Monday's 7-1 road win over the Milwaukee Brewers. He also scored twice and drew two walks. The 27-year-old superstar crushed an Aaron Civale offering 404 feet the opposite way to record his fifth long ball in 16 games since being reinstated from injury. Acuna Jr. has wasted no time reacclimating himself to big-league pitching, batting a strong .305 (18-for-59) with two doubles, eight RBI, and 12 runs scored (.999 OPS). While it's too small a sample to draw any definitive conclusions, the Venezuelan native's average exit velocity (97.1 MPH) and hard-hit rate (67.6%) would put him in the top 2% and 1% of batters, respectively, if they qualified.

St. Louis Cardinals catcher Ivan Herrera went 2-for-4 with a three-run home run in his team's 5-4 loss to the Toronto Blue Jays. He added a single for his second straight two-hit outing. The 25-year-old blasted his seventh long ball of 2025 off Blue Jays pitcher Yariel Rodriguez in the bottom of the eighth inning to cap a four-run rally and take their first lead of the matchup, 4-3. However, it wasn't enough to pick up the win. Herrera tallied a lone extra-base hit over a 15-game stretch that started in mid-May, but he's picked it up since then with three over the last five days -- including two homers. The Panama City native has cooled some, but is still slashing a robust .322/.397/.568 with eight doubles, 31 RBI, and 19 runs scored (34 appearances).

From RotoBaller

Athletics second baseman Max Muncy went 2-for-4 with a two-run home run in his team's 7-4 loss to the Los Angeles Angels. The 22-year-old added a single and notched his first steal of the season. Muncy launched his fourth homer in the top of the ninth inning, but that'd be the final hit his team could muster. He's gone yard in back-to-back games and thrice since being recalled last Wednesday. The A's No. 6 prospect wasn't so successful in the majors before being sent down to Triple-A. However, upon his demotion, he slashed an excellent .325/.397/.504 with 22 RBI, 24 runs scored, 11 doubles, a triple, and three homers (31 games). He's 6-for-21 (.286) in five June appearances.

Los Angeles Dodgers catcher Will Smith went 1-for-4 with a two-run home run in Monday's 8-7 road win against the San Diego Padres. He also picked up an RBI on a sac fly. Smith went yard for the sixth time this season in the top of the third off Padres pitcher Nick Pivetta, scoring teammate Freddie Freeman to give LA a 5-3 lead. He's been superb this season, batting .320 (56-for-175) with the second-highest on-base percentage in the league (.423) behind only Aaron Judge. The Louisville product is chasing at his lowest rate since 2020 (18.8%), and drawing a walk at a 15.0% clip, which puts him amongst the top 5% of all hitters.
