Mariners Hiring Jason Kanzler as New Manager
The Seattle Mariners are hiring former Chicago Cubs' director of player development Jason Kanzler as their new manager, a source told Alden Gonzalez of ESPN. Houston Astros manager Joe Espada had been among the finalists to land the job in Seattle, but it will instead go to Kanzler in an unconventional move by the Mariners. Kanzler, 36, will be replacing Dan Wilson after he was fired following the team's disappointing 2026 season. Kanzler has never managed at any level, but he will be inheriting one of the league's deepest, most talented rosters. Seattle has stars in outfielder Julio Rodriguez and catcher Cal Raleigh, not to mention some of the best starting-pitching depth in baseball. Kanzler is a former outfielder who was drafted in the 20th round in 2013. He previously spent five years with the Houston Astros, serving as a major-league coach in 2022 and 2023. He was hired by the Cubs as their director of player development at the start of the 2024 campaign. Kanzler will be the third skipper to serve under general manager Jerry Dipoto, who was brought in near the end of the 2015 season.

Rocco Baldelli Withdraws From Mariners' Managerial Search
Los Angeles Dodgers special assistant Rocco Baldelli has withdrawn from the search for a new Seattle Mariners manager, according to a report from The Athletic's Ken Rosenthal. Rosenthal reports that Baldelli has cited "family considerations" in withdrawing his name from consideration for the Mariners' open position. Baldelli currently serves as a special assistant to the president of baseball operations with the Dodgers. He was previously the manager of the Minnesota Twins from 2019 to 2025 and was the American League Manager of the Year in 2019 and won three AL Central division titles.

Managerial Candidates Emerging For Mariners Job
According to The Athletic's Chandler Rome, two former members of the Houston Astros staff -- Joe Espada and Jason Kanzler -- have emerged as serious candidates in the search for a new Seattle Mariners manager. Kanzler was on the Astros' 2022 staff and is now the Cubs farm director. And The Athletic's Ken Rosenthal added that Rocco Baldelli, the Dodgers' special assistant, is also in the mix for the Mariners job. The Mariners finished 76-86 overall and in third place in the AL West behind the Houston Astros, who finished with an 81-81 record to win the division. The Astros parted ways with Espada this offseason after the team lost to the Chicago White Sox in the postseason.

Joe Espada Set to Interview for Mariners Manager Job
The Seattle Mariners are set to interview current Houston Astros manager Joe Espada for their managerial vacancy, per Chandler Rome of The Athletic. While Espada is currently employed by Houston, Rome reports that his future with the organization is "in doubt" as his contract expires at the end of October. Espada has been the manager of the Astros since the start of the 2024 season. Houston has reached the playoffs twice under his watch, but they've failed to win a postseason game and have also seen their regular-season record get worse every year. The Mariners parted ways with former manager Dan Wilson shortly after the conclusion of the 2026 season. Seattle won just 76 games this year, but the team has plenty of returning talent. If Espada gets the Mariners job, he will be under pressure to win immediately in Seattle.

Mariners Top Infield Prospect Michael Arroyo to Join Major Leagues
The Seattle Mariners are promoting top infield prospect Michael Arroyo to the major leagues prior to Sunday's game against the Athletics, according to Daniel Kramer of MLB.com. Arroyo ranked as the Mariners' No. 3 prospect in the latest MLB Pipeline farm system rankings. He was originally signed as an international free agent out of Colombia in 2022. He was promoted from Double-A to Triple-A in the middle of the 2026 season, slashing .283/.359/.471 with 18 home runs, 81 RBI, 17 steals, and 117 wRC+ between the two affiliates. He also racked up an 8.1% walk rate and a 16.4% strikeout rate in the minors. Arroyo played the left side of the infield early in his minor league career, but he has only played second base and left field in 2026. He'll make his MLB debut on Sunday afternoon, batting eighth and playing second base.

Michael Arroyo Making Push For Promotion to Mariners
Seattle Mariners second base/outfield prospect Michael Arroyo already has six RBI in his first four September games at Triple-A Tacoma and is continuing to show why he is one of the top prospects in the Mariners system. The Mariners No. 3 overall prospect, Arroyo is a well-rounded player with a 55-grade hit tool and 55-grade power with 50-grade speed. Between two minor league levels this season, Arroyo has a combined 18 homers and 17 stolen bases with a .286 batting average and looks like a consistent, five-category performer. As someone who can play second base or be shifted to the outfield, Arroyo has some versatility to his game. He is looking like he will be a plus fantasy contributor when he is called up to the majors, and he looks like someone the Mariners could use with his all-around game and his positive versatility.

Michael Arroyo Could be Next Mariners Prospect to Debut
Seattle Mariners infield/outfield prospect Michael Arroyo cooled after a hot start to his Triple-A campaign, but is heating up again for Tacoma, going 8-for-26 (.308) with a double, a triple, a home run, one stolen base, and a 3:4 BB:K over his last seven games for the Rainiers. It brings the slash line to .271/.349/.481 for the Mariners' top offensive prospect, with eight home runs and three steals in 44 games since being promoted to Triple-A in early July (18 home runs, 16 steals in 109 games including Double-A). The jump to the higher level has not fazed him, with virtually identical strikeout (16.7 percent) and walk rates (8.1 percent), along with a 10-point improvement in OPS (.830). The Mariners have aggressively promoted other top prospects this season, with Colt Emerson, Kade Anderson, and Lazaro Montes all making their debuts in 2026, and Arroyo could be next in line. With solid hit, power, and speed tools, the 21-year-old possesses a solid all-around skill set that could make him a sneaky fantasy option down the stretch if he were to get regular at-bats, making him a stash-worthy option in deeper 12+ team leagues.

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.

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.

Michael Arroyo Adjusting Well To Triple-A
Seattle Mariners middle-infield prospect Michael Arroyo has adjusted nicely since his call-up to Triple-A Tacoma. In 36 games with the Rainiers, Arroyo has hit .275 with seven homers and 30 RBI with 29 runs scored. The infield prospect comes in at No. 3 on the Mariners' updated prospect list and has a 55-grade hit tool with 55-grade power and 50-grade speed. Signed out of Colombia, Arroyo has fared well in his minor-league career and has one more step to go in his progression to complete the journey to the MLB. At age 21, Arroyo is worth taking a chance on in fantasy leagues, as the right-handed hitter could see a call-up to Seattle before the end of this season. He likely needs a bit more time in Triple-A to adjust, but the Mariners could reward the youngster with a promotion soon.

Cole Young's Stable Production Floor Gives Him Deep-League Appeal
Across 501 plate appearances in 2026, Seattle Mariners second baseman Cole Young is hitting .260/.318/.405 with 15 home runs, 56 RBI, 58 runs scored, and three stolen bases. The 23-year-old's underlying batted ball metrics are underwhelming, as he's posted a 4.7% barrel rate and a 39.1% hard-hit rate. However, Young has quietly made some power gains over the course of the season. After hitting just four homers through his first 237 trips to the plate, Young has gone deep 11 times in his last 264 plate appearances. Young has also logged a strong 16.4% strikeout rate, which keeps his batting average floor high. He may not offer tremendous fantasy upside, but Young is locked into everyday playing time in Seattle and brings a stable production floor. In deeper leagues, Young is worth targeting on the waiver wire.

Michael Arroyo Looking Like Strong Stash Candidate
Seattle Mariners infield/outfield prospect Michael Arroyo has adjusted well since being promoted to Triple-A Tacoma on July 7. In 32 games with Tacoma, Arroyo has hit .286 with six homers and 27 RBI to go with 26 runs scored. The 21-year-old, with the ability to play infield or outfield, is quickly rising up the prospect rankings for Seattle and is now the No. 3 prospect in the Mariners' system. He boasts a 55-grade hit tool and 50-grade power and speed. He's totaled 15 stolen bases between Double-A Arkansas and Tacoma and has proven he can be a threat on the base paths. With his position versatility, look for Arroyo to get an opportunity at some point this year with the big league club. When he does, he should be a good addition to fantasy squads because of his all-around game and his power-speed combination.

Michael Arroyo Could Be Next Prospect to Earn the Call in Seattle
Seattle Mariners middle-infield prospect Michael Arroyo has fared well at Triple-A Tacoma since his promotion and could be next in line for a call-up to Seattle, following in the footsteps of Tacoma teammate Brock Rodden. Arroyo has played in 31 games for Tacoma this season and has six homers and 27 RBI while hitting .295. Arroyo, the right-handed hitter out of Colombia, is the No. 3 prospect on the Mariners list. The infielder has a balanced profile with a 55-grade hit tool and power with 50-grade speed. At age 21, he could be ready for his next step to the majors but might need a little more time at Triple-A. Nonetheless, he is looking like a good stash candidate and one that could reward fantasy managers with five-category production given an opportunity to make his MLB debut.

Michael Arroyo Making the Case for MLB Call-Up
Seattle Mariners second base/outfield prospect Michael Arroyo was already hitting well since his promotion to Triple-A, but the power potential has been on full display as of late. The Mariners' fourth-ranked prospect has belted a home run in three of his last four contests for Tacoma; he's now hit eight doubles, a triple, and six home runs in 26 games with the Rainiers. The 5-foot-10 Colombian is slashing a robust .327/.395/.582 during his time at Triple-A, while striking out at a better-than-average rate of 17.8 percent (8.5 percent walk rate), and he's stolen two bases thus far. The right-handed hitter has played a lot of outfield this year, in addition to his usual second base, which should give him multiple paths to the majors. At the moment, however, there is no room on the major league roster, so a call-up does not appear to be imminent. Nevertheless, the 21-year-old's skillset makes him one of the better offensive stash options out there, so managers with an NA spot available could tuck him away there in hopes of a late-season debut.

Michael Arroyo Producing at Triple-A But Has Tough Path to MLB Playing Time
Seattle Mariners second base/outfield prospect Michael Arroyo has been good since his promotion to Triple-A Tacoma, batting .324 in 24 games with the Rainiers to go with four homers, 22 RBI, and 22 runs scored. Arroyo is the No. 5 prospect in the Mariners system and boasts a 55-grade hit tool with 55-grade power and a 50-grade run tool. The 21-year-old second base/outfielder is making a real push for a chance at an MLB debut. Cole Young is currently atop the depth chart at second base for Seattle, and the outfield is full of some veteran players. Barring an injury, it might be a hard path to clear playing time for Arroyo. He's looking like he might be a wait-and-see at this point, especially after Seattle traded for Taylor Ward in the outfield. Arroyo, at just 21 years old, is showing great signs at Triple-A, so the Mariners may want to give him a shot at the big leagues, but it's difficult to stash him late this season.
