Bryce Miller Temporarily Demoted to Bullpen
According to Daniel Kramer, Seattle Mariners starting pitcher Bryce Miller is temporarily being moved to the bullpen. Mariners manager Dan Wilson confirmed the news on Friday that the struggling right-hander will shift to the pen for now. Over his last eight starts, Miller is 0-6 with a horrendous 7.19 ERA. It doesn't sound like Miller is fully healthy right now, so they might move him to the Injured List if he continues to struggle. The Mariners will go with a traditional five-man rotation with Miller getting the boot. Miller will likely pitch in low-leverage spots, which won't result in much fantasy value.

Lazaro Montes Continues to Hit With Power In Minor Leagues
Seattle Mariners outfield prospect Lazaro Montes is still hitting with power in the minor leagues, with nine homers and 19 RBI in August with Triple-A Tacoma. This season, between Double-A Arkansas and Triple-A Tacoma, Montes has combined to hit .248 with 37 homers and 93 RBI with 96 runs scored. The power-hitting skills are elite for Montes, the No. 5 overall prospect for the Mariners. He is blessed with 65-grade power but just a 45-grade hit tool. So he will need to improve his overall batting skills before he is able to earn a promotion to the big leagues. But the Mariners could use the power that he provides, making him a tempting call-up at the end of this season. Fantasy managers will want to monitor closely how the Mariners use Montes as this season winds down.

Michael Arroyo Could Be Next Mariners Hitter to be Called Up
Seattle Mariners new top middle-infield prospect Michael Arroyo is an accomplished infielder who could make a difference as a late-season call-up to the Mariners. The 21-year-old has hit well since his promotion to Triple-A Tacoma. In 41 games with Tacoma, Arroyo has eight homers and 35 RBI while hitting .271 with 31 runs scored. At Double-A Arkansas this season, Arroyo hit 10 homers and drove in 40 runs while hitting .287. The right-handed hitter is the No. 3 prospect in the Mariners system behind pitchers Kade Anderson and Ryan Sloan. Arroyo was signed out of Colombia and has a 55-grade hit tool and 55-grade power with 50-grade speed. Arroyo could be a nice addition to fantasy teams down the stretch and could provide five-category contributions to fantasy rosters.

Kade Anderson Can Make a Difference Down the Stretch
The Seattle Mariners called up their top pitching prospect last weekend in left-hander Kade Anderson, and he nearly recorded a quality start in his major-league debut against the Chicago Cubs, allowing three runs (two earned) on five hits (two homers) while walking two and striking out five in 5 2/3 innings pitched last Saturday. The 22-year-old southpaw, who is ranked as Seattle's top overall prospect at MLB Pipeline, threw four shutout innings last Saturday before allowing two solo home runs in the sixth frame. MLB Pipeline also has Anderson ranked as the top left-handed pitching prospect in all of baseball after the former third overall pick from LSU went 10-1 with a 1.06 ERA, 0.64 WHIP, and 135:13 K:BB in 93 1/3 innings across 18 starts at Double-A Arkansas this year before getting the call to the Show. Anderson, who is already rostered in nearly 60% of Yahoo leagues, can absolutely be a difference-maker for fantasy pitching staffs in the final month of the regular season in September, and he will have a plus second matchup as a member of the M's this weekend in Toronto against the Blue Jays. Scoop him up now if you need starting pitching help.

Julio Rodriguez Continues Sluggish Play
Seattle Mariners outfielder Julio Rodriguez has not been able to put it together at the plate this season. Fantasy managers have stayed hopeful that Rodriguez would figure it out, but it hasn't happened yet. Over the last two weeks, Rodriguez is 10-for-57 with one home run, four RBI, and two stolen bases. The three-time All-Star still has 20 homers and 17 steals, which is good, but fantasy managers expect more out of Rodriguez. The 25-year-old still has a month left in the regular season to turn it around and help his team make the postseason. At this point, fantasy managers can't really do anything but stick with Rodriguez and hope things turn around.

J.P. Crawford Reinstated from 10-Day Injured List on Tuesday
The Seattle Mariners reinstated infielder J.P. Crawford (wrist) from the 10-day injured list on Tuesday, optioning infielder Leo Rivas to Triple-A Tacoma as the corresponding move. Crawford had been sidelined since late July due to left wrist inflammation. Across 364 plate appearances on the year, the 31-year-old is hitting .212/.330/.345 with 10 home runs, 30 RBI, 38 runs scored, and one stolen base. Crawford's 6.4% barrel rate and 35.3% hard-hit rate are both subpar, but his stellar 13.7% walk rate provides him with a relatively stable floor at the plate. With Mariners infielders Brendan Donovan (concussion) and Colt Emerson (wrist) both on the injured list, Crawford should also be in line for everyday playing time on the left side of the infield. He's starting at third base and batting eighth on Tuesday night against the Philadelphia Phillies.

Cal Raleigh has First Career Three-Homer Game on Monday
It has been a rough 2026 season for Seattle Mariners catcher Cal Raleigh, but he had a bright spot in Monday night's 9-2 win over the visiting Philadelphia Phillies, going 3-for-3 at the plate with three home runs, four RBI and a walk. It was the 29-year-old left-handed slugger's first three-homer performance of his career and his first multi-homer showing of the season. Despite the monster game at T-Mobile Park, the Big Dumper is still slashing only .167/.282/.336 with a .618 OPS, 17 home runs, 51 RBI, 31 runs scored, two stolen bases, and a 30.9% strikeout rate in his 408 plate appearances in 2026. The poor season comes after Raleigh was a first-time All-Star and finished second in the American League MVP voting just last year after he finished with a league-high 60 home runs and 125 RBI in 159 regular-season games played. Raleigh can still make a power impact for fantasy managers down the stretch this year, but he almost certainly will finish shy of the 30-homer mark for the first time since his first full year in the league in 2022.

Bryan Woo 100 Percent Confident he Can Start on Wednesday
Seattle Mariners right-hander Bryan Woo (shoulder) is "100% confident" that he can make his scheduled start on Wednesday at home against the Philadelphia Phillies, according to The Seattle Times' Adam Jude. Woo had his last start on Aug. 16 cut short due to soreness in his right shoulder, and the Mariners skipped his last scheduled start over the weekend against the Chicago Cubs. The 26-year-old threw a successful bullpen session on Sunday, though, and thinks he will be cleared to toe the rubber this Wednesday. Fantasy managers will want to be cautious with his start this week while coming off an injury, although he will be on extra rest. Woo allowed 10 earned runs with four walks and 13 strikeouts in 10 innings in his final two starts of July against the Texas Rangers and Los Angeles Dodgers, but he's rebounded in three starts in August against the Detroit Tigers, New York Yankees, and Astros, allowing just two earned runs with three walks and 15 strikeouts in 18 innings pitched. He is 9-8 in 2026 with a 4.10 ERA (3.29 FIP) and 1.08 WHIP with 137 strikeouts and only 29 walks in 138 1/3 innings across his 24 starts on the year in his fourth year in the majors.

Colt Emerson to Have Season-Ending Wrist Surgery on Wednesday
Seattle Mariners rookie infielder Colt Emerson (wrist) is scheduled to have season-ending wrist surgery on Wednesday, according to Adam Jude of The Seattle Times. There was a lot of excitement around Emerson, one of the team's top overall prospects, making his major-league debut in 2026, but it did not last long. The 21-year-old left-handed-hitting infielder struggled with big-league pitching in his first 69 games and 241 plate appearances, slashing .190/.246/.335 with a .581 OPS, eight home runs, six doubles, a triple, 23 RBI, 24 runs scored, three stolen bases, 15 walks, and 83 strikeouts. It was not what Emerson, his fantasy managers, or the Mariners expected, but the good news is that the young infielder is expected to be ready for the start of spring training early in 2027. Barring a setback with his wrist injury, Emerson is still in line as the club's starting shortstop over the long term, so fantasy managers in dynasty/keeper leagues should be looking to buy low on the shortstop prospect this winter. Brock Rodden is starting at the 6 on Monday for the M's, but veteran J.P. Crawford (wrist) could come off the injured list as early as Tuesday to regain starting shortstop duties.

Bryce Miller Loses Consecutive Starts by at Least 17 Runs
Seattle Mariners right-hander Bryce Miller became the first pitcher since George Van Haltren of the 1890 Brooklyn Wonders to lose consecutive starts by at least 17 runs, according to ESPN Insights. In the Mariners' 19-2 loss to the Chicago Cubs on Sunday, Miller allowed six earned runs on two hits (two homers) while walking seven and striking out five in 4 1/3 innings for his eighth loss of the year. In his previous outing, a 22-0 shutout loss to the Milwaukee Brewers, he gave up six runs (five earned) on seven hits (one homer) while walking two and striking out three in 4 2/3 innings. The Seattle Times' Adam Jude reports that Miller admitted after Sunday's loss that he has dealt with a minor right-lat injury since his July 24 start against the division-rival Texas Rangers. He allowed five earned runs to Texas on that day and has a 7.92 ERA with 15 walks and 21 strikeouts in 30 2/3 innings in his last six starts for Seattle. Fantasy managers should be avoiding Miller in his next scheduled outing this Sunday against the Toronto Blue Jays, and he could be relegated to the bullpen once Bryan Woo returns from his shoulder injury.

Michael Arroyo Emerging as Sneaky Stash Target with Clear Path to At-Bats
Seattle Mariners infield prospect Michael Arroyo is emerging as a potential late-season call-up. Arroyo began the 2026 season at the Double-A level but has since moved up to the top club. Through his first 65 games of the Double-A season, Arroyo held a .287/.364/.456 slash line with 12 doubles, 10 home runs and 13 stolen bases. This production earned him a call-up to Triple-A Tacoma. Through his first 38 games with the top club, Arroyo has held a sharp .270/.341/.472 line with nine doubles, seven home runs, and two stolen bases. With Brendan Donovan shifting back to the injured list and Colt Emerson being demoted to Triple-A, Arroyo does have a path to emerge as a potential option for the Mariners as they look to claim a spot in the postseason.

Lazaro Montes Slugging His Way to MLB Debut
Seattle Mariners outfield prospect Lazaro Montes has enjoyed a power binge at Triple-A and has put himself in a prime position to join the Mariners for the final stretch. Over his last 18 games at the top club in the system, the top outfield prospect has been nothing short of dominant. During this noted stretch, Montes has launched nine home runs and added four doubles while carrying a .324/.415/.761 line. Through 38 total games at the Triple-A level, the 21-year-old has held a .286/.369/.597 line with 12 long balls. Earlier in the season, Montes appeared in 79 games at Double-A, where he posted a .234/.369/.550 line with 25 round-trippers. Given his immense power upside and recent surge, Montes may not only debut later this season, but also provide a high-impact down the stretch.

Bryan Woo Encouraged After Throwing Bullpen Session
Seattle Mariners right-hander Bryan Woo (shoulder) said he is encouraged coming out of a bullpen session on Sunday, according to Adam Jude of The Seattle Times. Woo never thought his season was in jeopardy after being pushed back from his scheduled start against the Chicago Cubs this weekend, but he wants to be cautious about pushing through discomfort in his right shoulder. No decision has been made about when he will make his next start. The M's pulled the 26-year-old after just 75 pitches in his most recent start last Sunday against the division-rival Houston Astros, when he allowed only two earned runs with a walk and five strikeouts in six innings for his ninth win of the year. Woo allowed 10 earned runs in 10 innings to the Texas Rangers and Los Angeles Dodgers in his last two starts in July, but he has given up just two earned runs with three walks and 15 K's in his three starts so far in August. Seattle has an upcoming three-game series with the Philadelphia Phillies on Monday, followed by a three-game series next weekend in Toronto against the Jays.

Brendan Donovan Goes on Concussion Injured List
Seattle Mariners infielder/outfielder Brendan Donovan (concussion) was placed on the 7-day concussion Injured List, retroactive to August 22. This comes a day after Donovan was hit in the head while in the batting cage before Saturday's game. He'll now be sidelined for at least the next week while he goes through the league's concussion protocols. In a corresponding move, third baseman Patrick Wisdom was recalled from Triple-A Tacoma to replace Donovan on the roster. Weston Wilson will operate at third base during Sunday's game against the Chicago Cubs.

Lazaro Montes Keeps Hitting With Power at Triple-A
Seattle Mariners outfield prospect Lazaro Montes continues to show off his power stroke this season in the minors. Montes has eight homers and 18 RBI in August with Triple-A Tacoma and is up to 36 homers and 92 RBI between Double-A Arkansas and Tacoma this season. The left-handed hitter is the No. 5 prospect in the Mariners' system and has 65-grade power. Montes, signed out of Cuba, would offer nice power potential for fantasy teams if given a shot at promotion to Seattle. Fantasy managers can take a chance on Montes this season, but there is a good shot that he will not make his big-league debut until next season. At 21 years old, Montes could use a bit more minor league seasoning, but looks like a player who will make a big-time impact in the major leagues when he debuts.
