Michael Arroyo Off to Hot Start at Triple-A, In Position for Late-Season MLB Debut
Seattle Mariners infield prospect Michael Arroyo was recently promoted to the Triple-A club and has not slowed down since moving up to the top ranks. Through his first six contests with Tacoma, the team's No. 4 prospect has held a .346/.406/.731 line with a dominant 1.137 OPS. During this stretch, Arroyo has launched two long balls and swiped two bags. He spent the majority of the first half with Double-A Arkansas, where he carried a .287/.364/.456 line with 12 doubles, 10 home runs, and 13 stolen bases. Fantasy managers in deeper leagues should continue to pay close attention to his production as he has put himself firmly on the stash radar. He may only need a brief seasoning at this level before being given the green light to join the Mariners for the final stretch.

Brendan Donovan Could Start Rehab Assignment Any Day Now
Seattle Mariners infielder/outfielder Brendan Donovan (groin) worked out on Tuesday in Arizona and will go through another workout on Wednesday, according to Ryan Divish of The Seattle Times. The hope is that he will start playing in minor-league rehab games in the rookie-level Arizona Complex League after that. The 29-year-old utility man is making progress, but he's not going to be ready to rejoin Seattle's major-league roster before the end of the first half of the season this Sunday. Depending on how Donovan's rehab assignment goes, though, he could be ready for the start of the second half on Friday, July 17. The former seventh-rounder of the St. Louis Cardinals in 2018 out of the University of South Alabama was expected to be a key contributor for the M's in 2026, but he's managed to play in just 25 games due to injuries, going 23-for-84 (.274) with three homers, eight RBI, nine runs, and a stolen base. Donovan is more attractive in real baseball than fantasy because of his low power/speed ceiling, but he hits for average and is eligible at second base, third base, shortstop, and outfield in Yahoo leagues. He's currently rostered in just under half of Yahoo leagues.

Michael Arroyo to Join Triple-A Tacoma, Emerging as Viable Stash Candidate?
Seattle Mariners infield prospect Michael Arroyo was promoted to Triple-A Tacoma earlier on Sunday evening, according to Daniel Kramer of MLB.com. Arroyo is currently viewed as the team's No. 5-ranked prospect and the overall No. 45 prospect on MLB.com. The infielder has spent the first half of the season in Double-A and is being rewarded with an early promotion. Across 65 games with Double-A Arkansas, Arroyo has posted a strong .287/.364/.456 line with 12 doubles, 10 home runs, and 13 stolen bases. Last summer, Arroyo split his time between High-A and Double-A, where he carried an overall .262/.401/.433 line with 17 home runs and 12 stolen bases. While an MLB debut may not occur until late in the season, his five-category profile makes him a worthy stash candidate in deeper 15-team leagues with N/A spots as he is now on the doorstep of the majors.

Brendan Donovan to Start a Rehab Assignment on Tuesday
Seattle Mariners infielder/outfielder Brendan Donovan (groin) will start a minor-league rehab assignment on Tuesday, according to Ryan Divish of The Seattle Times. Donovan has been sidelined with a strained left groin since the middle of May, but barring a setback on his rehab assignment, he could return just before the All-Star break and play with the M's next weekend. The 29-year-old former seventh-rounder by the St. Louis Cardinals in 2018 from the University of South Alabama was a first-time All-Star in 2025 in his final year in St. Louis, slashing .287/.353/.422 with a .775 OPS, 10 homers, 50 RBI, 64 runs scored, and three stolen bases in 118 games and 515 plate appearances. Donovan has a limited fantasy ceiling because of his middling power and speed, but his high-contact approach makes him appealing for his high average and on-base percentage, not to mention he's eligible at second base, third base, shortstop, and the outfield in Yahoo leagues. He's currently rostered in just under half of Yahoo leagues.

Colt Emerson a Must-Add Waiver-Wire Target Ahead of Second-Half Breakout?
Since being promoted to the big leagues in mid-May, Seattle Mariners infielder Colt Emerson has emerged as his team's everyday shortstop. Across 116 plate appearances, the 20-year-old is hitting .212/.293/.481 with seven home runs, 17 RBI, 15 runs scored, and one stolen base. Emerson's underlying metrics are a bit concerning, as his strikeout rate (31.9%) is higher than his hard-hit rate (31.3%). Still, Emerson has gotten to some power at the MLB level, and he's widely considered one of the top prospects in all of baseball. Emerson stole 10 bases across 38 games at Triple-A before his promotion, so he has some untapped speed potential once he starts getting on base more consistently. Given his upside, Emerson profiles as a worthy waiver wire target despite some of his early struggles in the big leagues.

Should Colt Emerson be Considered a Priority Waiver-Wire Target?
Across 94 plate appearances since making his MLB debut in mid-May, Seattle Mariners infielder Colt Emerson is hitting .235/.309/.529 with six home runs, 16 RBI, 13 runs scored, and one stolen base. The 20-year-old has struggled with swing-and-miss, posting a 29.8% strikeout rate that may put a ceiling on his batting average. However, he's shown off his power stroke in recent weeks and has already hit four home runs in June. Emerson has also established himself as the everyday shortstop in Seattle, with veteran Mariners infielder J.P. Crawford being moved from shortstop to third base upon his return from a hand injury earlier this month. Emerson's underlying contact metrics (5.3% barrel rate, 29.8% hard-hit rate) do not support his power output so far, which should be a bit of a red flag for fantasy managers. Still, Emerson is considered to be one of the top prospects in all of baseball and hit seven home runs across 169 plate appearances at Triple-A this season before his promotion. Given his prospect pedigree and his role in Seattle, Emerson profiles as a priority waiver wire target.

Brendan Donovan Begins Running Progression, Return Imminent?
Seattle Mariners infielder/outfielder Brendan Donovan (groin) started a running progression on Tuesday, which is the biggest hurdle to clear as he attempts to return from a strained left groin, according to Daniel Kramer of MLB.com. Donovan's running progression is expected to last 10 days to two weeks, so his return to the big-league roster isn't imminent. From there, if he avoids any setbacks, Donovan could go straight into a minor-league rehab assignment. The 29-year-old left-handed hitter has been sidelined since the middle of May, but barring a setback, he will have a shot to rejoin the big-league squad before the All-Star break in mid-July. Donovan is a contact-oriented utility man who was starting regularly at third base for Seattle before his injury, hitting .274 (23-for-84) with three homers and eight RBI in just 25 games played. When he's ready to return, he should return to an everyday role with the M's, which could push infielder J.P. Crawford to the bench. Donovan is currently rostered in just over half of Yahoo leagues.

J.P. Crawford Activated and Starting at Third Base on Tuesday
The Seattle Mariners announced on Tuesday that they reinstated infielder J.P. Crawford (hand) from the 10-day injured list due to a right-hand contusion, and he's starting at third base and batting leadoff in his first game back in Tuesday's series opener against the Baltimore Orioles and right-hander Brandon Young. The 31-year-old veteran spent the minimum time on the IL with a minor right-hand contusion that he suffered after getting hit by a pitch. Now that he's back, he could spend most of his time in Seattle at the hot corner with infield prospect Cole Emerson settling in at the 6. Crawford returns to an ugly .228/.356/.409 slash line with a .766 OPS, 10 home runs, 23 RBI, 31 runs scored, and a stolen base in his 193 at-bats in 2026. He has now reached double-digit home runs in three of the last four seasons, and he's only striking out 18.9% of the time. Still, Crawford is only rostered in 11% of Yahoo leagues with minimal power for a player with shortstop eligibility. He was heating up at the plate before landing on the IL, hitting .333 with four home runs in his last 11 contests.

Colt Emerson Showing More Power in Second Month in the Big Leagues
Seattle Mariners infield prospect Colt Emerson, who is ranked as the team's top prospect at MLB Pipeline, has delivered a .237/.310/.566 slash line, .875 OPS, six home runs, 14 RBI, 12 runs scored, six walks, and 24 strikeouts in 84 plate appearances across his first 23 games in the majors. At the shortstop position, MLB Pipeline has Emerson ranked at No. 4, behind only the Brewers' Jesus Made, the A's prospect Leo De Vries, and Nationals shortstop prospect Eli Willits. Emerson, the 22nd overall pick in 2023, doesn't turn 21 until late July. He has plenty of maturing to do as a hitter, especially since he's not an elite athlete. However, Emerson showed in the minors that he can provide a strong hit tool while also developing his power. He hit .244 (10-for-41) with two homers and seven RBI in 13 games in May, and he's gone 8-for-35 (.229) so far in June with four homers, two doubles, and seven RBI in 10 games played. Even with regular shortstop J.P. Crawford (hand) expected to return from the injured list this week, Emerson should play regularly at third base in Seattle, and his emerging power from the left side of the plate makes him an attractive young infield target in deeper fantasy leagues. The 6-foot, 195-pounder is currently rostered in only 24% of Yahoo leagues.

J.P. Crawford Expects to Return on Tuesday, Set to Play Third Base in Seattle?
Seattle Mariners shortstop J.P. Crawford (hand) said that he expects to be activated from the 10-day injured list on Tuesday, per Daniel Kramer of MLB.com. Kramer also reports that Crawford has been taking grounders at third base "almost exclusively" during the team's current road trip. While Crawford made 53 appearances at shortstop this season before the injury, Mariners prospect Colt Emerson has taken over as the team's everyday shortstop in Crawford's absence. It appears that Seattle could be planning a position change for the veteran, who has graded out as a poor defender at short by the advanced metrics over the past couple of seasons. Across 233 plate appearances before the hand injury, Crawford hit .228/.356/.409 with 10 home runs, 23 RBI, 32 runs scored, and one stolen base. Moving to third base could allow him to maintain everyday playing time in Seattle, at least until Mariners infielder Brendan Donovan (groin) makes his return from a groin strain.

Colt Emerson Returns to M's Lineup Following Bout With Back Spasms
Seattle Mariners rookie infielder Colt Emerson (back) is starting at shortstop and will bat ninth for Seattle in Thursday's series finale against the hosting Baltimore Orioles and right-hander Kyle Bradish at Camden Yards, according to MLB.com. Emerson didn't play in any of the last three games due to a bout with back spasms, but he's feeling good enough to play on Thursday. The 20-year-old infield prospect is one of the most intriguing young power/speed threats in baseball, although he won't carry a ton of DFS appeal at the bottom of the Mariners' batting order in his return. In his first 19 games in the big leagues, Emerson has gone 15-for-62 (.242) with four home runs, five doubles, a triple, 10 RBI, and nine runs scored across 69 plate appearances. He will play regularly for the M's at the 6 with J.P. Crawford (hand) on the injured list currently. Emerson has only five walks and 21 strikeouts early on, so he'll need to make more contact to capitalize on his potential.

Colt Emerson Out Again With Back Spasms, Likely to Avoid Injured List
Seattle Mariners rookie infielder Cole Emerson (back) remains out of the starting lineup on Wednesday against the Baltimore Orioles due to back spasms, but he took swings in the cages and is feeling a little bit better, according to Adam Jude of The Seattle Times. Emerson is expected to avoid a stint on the injured list. Cole Young is making another start at the 6 and is batting leadoff, with Miles Mastrobuoni starting at second base and hitting eighth against Orioles right-hander Brandon Young. It will be the third straight game that Emerson will start on the bench due to back spasms, but he could return to the starting nine as soon as Thursday's series finale at Camden Yards. With J.P. Crawford (hand) on the IL right now, Emerson will be Seattle's preferred option at shortstop when he recovers from his back injury. In his first 62 major-league at-bats, the 20-year-old former first-rounder in 2023 has hit .242 (15-for-62) with four home runs, five doubles, 10 RBI, and nine runs scored across 69 plate appearances. Emerson is one of the more intriguing young infield prospects in the majors.

Colt Emerson Remains Out on Tuesday With Back Injury
Seattle Mariners rookie infielder Colt Emerson (back) remains out of the starting lineup for Game 2 of the series against the hosting Baltimore Orioles at Camden Yards on Tuesday, according to MLB.com. Infielder Cole Young will make another start at the 6 and will bat eighth against Orioles left-hander Trevor Rogers. Emerson will miss a second straight game after he was scratched from Monday's series-opening win in Baltimore due to tightness in his back. The M's placed regular shortstop J.P. Crawford on the injured list on Monday with a hand contusion, so Seattle has become pretty thin up the middle of late. Ryan Bliss was recalled from Triple-A Tacoma and will make his second straight start at the keystone on Tuesday. Emerson, one of the top middle-infield prospects in the game, has hit .242/.319/.548 with an .867 OPS, four home runs, 10 RBI, and nine runs scored in his first 19 big-league games since being called up. Check back on Wednesday to see if he returns to the starting nine for the Mariners.

Colt Emerson Dealing With Back Tightness
Seattle Mariners rookie infielder Colt Emerson (back) was scratched from the lineup for Monday's series opener in Baltimore against the Orioles due to back tightness, according to Adam Jude of The Seattle Times. Infielder Cole Young made the start at the 6 for the M's against right-hander Trey Gibson. The Mariners placed regular shortstop J.P. Crawford (hand) on the 10-day injured list on Monday as well, so they're a bit thin at the position right now. The good news is that Emerson's injury isn't considered to be very serious, so he could return to the starting lineup at shortstop for Game 2 of the series at Camden Yards on Tuesday. Fantasy managers need to check back then. The 20-year-old former 22nd overall pick in 2023 is one of the most intriguing young infielders in the game. Through his first 19 major-league ballgames, Emerson has gone 15-for-62 (.242) with four home runs, 10 RBI, and nine runs scored across his 69 plate appearances. He's currently rostered in 27% of Yahoo leagues and has gone 5-for-21 (.238) with two homers, two doubles, three RBI, and three runs in six games so far in June.

J.P. Crawford Placed on Injured List With Hand Contusion
Seattle Mariners shortstop J.P. Crawford (hand) was placed on the 10-day injured list (retroactive to June 7) on Monday with a right-hand contusion, according to Daniel Kramer of MLB.com. Infielder Ryan Bliss has been recalled from Triple-A Tacoma in a corresponding move. Crawford will be eligible to return from the IL next Tuesday, when the Mariners start their homestand. The 31-year-old veteran was hit by a pitch on his hand late last week and needs a little more rest. He should be ready to return when eligible next week. In the meantime, Colt Emerson will continue to fill in as the M's primary shortstop, with Patrick Wisdom picking up more playing time at the hot corner in Seattle. Crawford is only rostered in 14% of Yahoo leagues at this point because of his limited fantasy ceiling across all categories. The 10-year veteran goes to the shelf hitting just .228 (44-for-193) on the season with 10 home runs, 23 RBI, 31 runs scored, and one stolen base in 233 plate appearances across 55 games played.
