Bryan Woo's Road Struggles Masking Second-Half Value?
Seattle Mariners starting pitcher Bryan Woo has not been automatic away from home, and that may be the only opening fantasy managers get in trade talks. The 26-year-old gave up nine hits, one walk, and four runs, three earned, over five innings Tuesday, July 7, against Miami. His home-road split is hard to ignore, with Woo sitting at 6-0 with a 2.10 ERA in Seattle and 1-6 with a 6.28 ERA on the road. The full profile is still a lot better than the road blowups. Woo has a 4.23 ERA, but the 1.07 WHIP, 102 strikeouts, 20 walks, and 3.06 FIP are not the numbers of a pitcher to panic-sell. Since he is already rostered in roughly 98% of leagues, this is a trade-market play, not a waiver chase. Check in if his manager is annoyed, but do not sell low.

Is Ryan Sloan the Next Mariners Pitcher to Debut?
Seattle Mariners right-handed pitching prospect Ryan Sloan has spent the entire 2026 season at the Double-A level but has been overshadowed by his teammate Kade Anderson. While Anderson has recently jumped Sloan on the team prospect board (on MLB.com), Sloan possesses nearly as much upside, sitting as MLB.com's No. 8 overall prospect and the team's No. 2 overall prospect. Through the first half of the 2026 season, the 55th overall pick from the 2024 MLB Draft has posted a 4.04 ERA and 1.19 WHIP over his first 62 1/3 innings at Double-A. He has struck out an impressive 77 hitters and walked only 12. During the 2025 season, Sloan made his professional debut and tossed 82 innings with a 3.73 ERA and a 1.16 WHIP over stints in the lower levels. Given Sloan's previous professional experience, the Mariners could turn to him first, rather than Anderson, when they need depth down the stretch. For now, Sloan is worth close monitoring, as a promotion to Triple-A could be imminent.

Kade Anderson's Elite Double-A Production Makes him a Priority Stash
Seattle Mariners pitching prospect Kade Anderson suffered his first loss at Double-A Arkansas following his July 3 start. He only allowed two earned runs to pick up his first loss of the season in his 8-1 overall record. His numbers look video game worthy with a 1.36 ERA and 0.69 WHIP with 108 strikeouts in 72 2/3 innings pitched. The No. 3 overall draft pick out of LSU has dominated the minors in his first season of professional baseball. Before a stop in Seattle and a spot in the Mariners rotation, Anderson would likely need some seasoning at Triple-A. So while his numbers call out for a stash for fantasy managers, some patience is required. Managers in mid-size leagues would be smart to use a roster spot now on Anderson and wait to see if it pays off. The prospect pedigree looks elite for Anderson, and it's worth using an early roster spot to acquire his services.

Is Kade Anderson the No. 1 Stash Target as he Continues to Deal at Double-A?
Seattle Mariners starting pitching prospect Kade Anderson has turned in a dominant June at Double-A Arkansas and is coming off a start in which he allowed his first two earned runs of the month. Overall, he completed June with a 4-0 record and an 0.79 ERA with 32 strikeouts in 22 2/3 innings pitched. It doesn't get much better than that at any level, and fantasy managers would like to see Anderson and his lefty dominance at the Triple-A level sooner rather than later. Anderson has shown a mastery of Double-A with an 8-0 record and 1.22 ERA with 99 strikeouts in 66 2/3 innings pitched. The talented former No. 3 overall pick would likely need some time in Triple-A before the Mariners take a look at him in Seattle. But his numbers show that he could be ready for a close-up and is definitely worth picking up and stashing off the waiver wire in leagues of all sizes.

Kade Anderson Dominating at Double-A, Worth a Stash Look
Seattle Mariners left-handed pitching prospect Kade Anderson was the No. 3 overall pick in the 2025 MLB Draft out of LSU. He is already showing off his dominant left-handed arsenal at Double-A. With the Arkansas Travelers, Anderson's numbers are sparkling, with an 8-0 record in 13 starts and a 1.22 ERA with 99 strikeouts in 66 2/3 innings pitched. He has pretty much done enough to get the call to Triple-A sooner rather than later. His record is flawless, his ERA is barely existent, but most impressive perhaps is his strikeout rate. That is what makes him the most enticing for fantasy purposes. Anderson looks like he could be impressive at the major-league level, but he does still likely need to prove himself at Triple-A before the Mariners call him up. While Anderson could hold his own right now at the big-league level, the Mariners have hinted that they most likely won't call him up until later in the second half of the regular season, and when they do, he could be used in a relief role.

Kade Anderson Won't Get Promoted Until the Stretch Run?
The Seattle Mariners have floated the idea of creating a "super 'pen" for the stretch run late in the season, perhaps featuring promotions for pitching prospects Kade Anderson and Ryan Sloan, according to Adam Jude of The Seattle Times. Anderson, the former third overall pick in 2025 out of Louisiana State University and the team's No. 2 prospect per MLB Pipeline, has dominated this year at Double-A Arkansas, going 8-0 with a stingy 1.22 ERA, 0.70 WHIP, and 99:10 K:BB in 66 2/3 innings across his 13 starts. It was reported in mid-June that the 21-year-old southpaw wasn't in Seattle's immediate plans for a big-league call-up, and this report by Jude corroborates that we probably won't see Anderson make his MLB debut until much later in 2026. He's currently rostered in 12% of Yahoo leagues, but fantasy managers in mixed redraft leagues won't have much incentive to hold him now, especially since he might not even pitch in a starting role if he joins the M's for the stretch run. But in dynasty/keeper leagues, Anderson is a must-stash for his clear high-end upside for 2027 and beyond.

Kade Anderson Poised for Second-Half MLB Debut?
Seattle Mariners top pitching prospect Kade Anderson has been nothing short of dominant in his first taste of professional action. Since joining the Mariners with the third overall pick in last year's MLB Draft, the former LSU standout was sent to Double-A to begin his professional career at the start of the 2026 campaign. With Double-A, the southpaw has looked incredible, logging 61 2/3 innings (12 starts) with a stellar 1.02 ERA and a 0.65 WHIP. During this stretch, Anderson has struck out 90 hitters while walking just eight. However, Seattle currently has a surplus of starting pitchers, which leaves Anderson without a clear path to debut in the near future. With the team opting to use a "piggyback" schedule to keep all six starters engaged, Anderson appears set to debut later in the second half. While his timeline remains undetermined, his upside on a per-start basis remains the highest out of any of the top prospect pitchers. Managers in leagues with N/A spots should still view the former third overall pick as a must-stash option heading into the first week of July.

Bryce Miller Continues Excellent Season, Strikes Out 11 in a Loss
Seattle Mariners right-hander Bryce Miller allowed two home runs and picked up his second loss of the year in Thursday's 5-1 defeat at the hands of the hosting Pittsburgh Pirates, but he still pitched extremely well. Miller allowed three earned runs on five hits while walking none and striking out a season-high 11 batters in 5 2/3 innings. The 27-year-old got off to a late start to the 2026 season while recovering from an injury, but he has been very strong in his first eight starts and now sports an ERA under 2.00. Miller has had at least seven strikeouts in each of his last four starts, and he hasn't allowed more than three earned runs in any of his 2026 starts yet. In addition to his nice 1.97 ERA, Miller will carry a 0.72 WHIP and 54:5 K:BB in 45 2/3 frames into an amazing matchup against the division-rival Los Angeles Angels his next time out. Based on how well Miller has looked in 2026, fantasy managers should consider him a must-start for his next outing against the Halos. Miller is now rostered in 80% of Yahoo leagues.

Kade Anderson Dominates Again, Could He Force His Way to Seattle for a Debut?
Seattle Mariners pitching prospect Kade Anderson is making Double-A look easy at this point, cruising through six innings in his latest start where he did not allow a run, yielding only two hits and a walk while striking out eight batters. It was the fifth consecutive start in which the lefty did not allow a run, a stretch of 27 2/3 innings, and he's also struck out at least six batters in each of those contests, with 39 strikeouts compared to just three walks. The former third-overall draft pick owns a pristine 1.02 ERA, 0.65 WHIP, and an elite 37.4 percent K-BB%, all of which are tops in the minor leagues out of all pitchers who have thrown at least 50 innings. The Mariners have made it known that the southpaw is not part of their immediate plans in the major league rotation, but a test at Triple-A certainly appears to be on the horizon, and while a major league debut does not appear to be imminent, this kind of elite performance makes the 21-year-old a top pitching stash thanks to his high-strikeout upside coupled with strong command. Stash in an NA spot if available.

Luis Castillo Allows Five Runs in Long-Relief Role, a Safe Cut in All Formats?
Seattle Mariners right-hander Luis Castillo entered his team's game against the Boston Red Sox on Friday night in the sixth inning and struggled, allowing five runs (four earned) on seven hits across four innings of work. The 33-year-old has generally pitched better since being moved from the rotation into a hybrid starter/reliever role, as he had allowed just six earned runs with 22 strikeouts across 23 innings (five appearances) since the switch leading into Friday. However, Castillo's overall line for the year remains ugly. Across 70 2/3 innings, he's recorded a 2-6 record with a 5.22 ERA, 1.40 WHIP, and 69 strikeouts. At this point, Castillo appears to be the clear odd man out in a Seattle rotation that includes Bryan Woo, Logan Gilbert, George Kirby, Bryce Miller, and Emerson Hancock. Barring an injury to one of the Mariners' top arms, Castillo is likely safe to drop in most fantasy formats.

Is Kade Anderson the Top Pitching Prospect to Stash?
Seattle Mariners left-handed pitching prospect Kade Anderson has seen his short-term fantasy stock take a hit this past week, but the budding ace remains firmly on the stash radar. The Mariners acknowledged that they will be looking to "piggyback" each of their MLB starters and do not view Anderson as part of their immediate plans. While this could change in the second half, for now it appears the former LSU superstar will remain in the minor leagues for the foreseeable future. However, during his first taste of professional baseball, the southpaw has looked nothing short of dominant, posting an elite 1.13 ERA, 0.66 WHIP, and an 82:7 K:BB over 55 2/3 innings of work. While his path to the majors is not overly clear, his upside remains elite, making him a top-stash candidate in standard formats with NA spots.

Logan Gilbert Fans 10 on Tuesday, Heating Up on the Mound
Seattle Mariners right-hander Logan Gilbert has pitched much better of late after a slow start to his 2026 season, and it continued on Tuesday night at T-Mobile Park in a 3-1 win over the visiting Baltimore Orioles. Gilbert allowed just one earned run on just two hits while walking one and striking out a season-high 10 in seven innings of work for his fifth win of the year and to drop his season ERA to 3.43. The lone run that the 29-year-old gave up on the night came in the first inning, and he settled in from there and retired 16 batters in a row at one point. The strong performance against the O's has the former 14th overall pick in 2018 out of Stetson University sitting at 5-4 on the season with a 3.43 ERA (3.79 FIP) and 1.03 WHIP with 92 punchouts and 20 walks in 86 2/3 innings across 15 starts in his sixth year in the majors. Since allowing a season-high seven earned runs on May 16, Gilbert has allowed five earned runs on 16 hits while walking eight and striking out 35 while going 3-0 in five starts. He should be considered a must-start as he heats up as he heads into a strong matchup versus the Boston Red Sox.

Kade Anderson Not Part of Mariners' Immediate Rotation Plans
Seattle Mariners pitching prospects Kade Anderson and Ryan Sloan are not part of the team's immediate plans, a source told Adam Jude of The Seattle Times, as the team reassesses its six-man rotation. The expectation remains for both Anderson and Sloan to figure into the mix at the big-league level by late summer, though. Per MLB Pipeline, Anderson is the club's No. 3 prospect, with Sloan sitting right behind him at No. 3. Anderson, the third overall pick last year out of Louisiana State University, has been absolutely dominant in his first full season of pro ball at Double-A Arkansas, going 6-0 with a 1.13 ERA, 0.66 WHIP, and 82:7 K:BB in 55 2/3 innings pitched across 11 starts. The 6-foot-2, 179-pounder is one of the best pitching prospects to stash in 2026, even in redraft formats. Right now, he's rostered in 11% of Yahoo leagues with his first MLB promotion coming sooner rather than later. Anderson lacks high-end velocity, but he makes up for it with excellent run up in the zone, and he also features two plus breaking pitches in a high-spin slider and curveball.

Kade Anderson Dominates Again, but Any Closer to MLB Debut?
Seattle Mariners pitching prospect Kade Anderson impressed yet again in his latest start at Double-A Arkansas, tossing 6 2/3 innings of scoreless ball on Saturday, allowing just three hits and no walks while striking out six batters. That is now four straight starts in which the southpaw has not allowed a run, and his third straight in which he did not walk a batter. The effort reduced his ERA for the season to 1.13 with a 0.66 WHIP and a 37.7 percent K-BB%, all of which lead the entire minor leagues for pitchers with at least 50 innings pitched. There is seemingly nothing left to prove at Double-A, so it's just a matter of time before the lefty earns a promotion to Triple-A Tacoma, at which point he'll be knocking on the door to the majors. The Seattle rotation isn't in need of reinforcements at the moment, but should Anderson continue to perform at a high level, a major league debut this season is very likely, and could possibly even happen by the end of July at this rate. That being the case, the former third-overall draft pick is one of the top arms to stash in redraft leagues for his multi-ratio-boosting upside.

Bryce Miller has Been Outstanding, Should be Rostered in More Leagues
Seattle Mariners right-hander Bryce Miller didn't make his 2026 season debut until the middle of May due to injury, but since returning, the 27-year-old has been outstanding for the Mariners. The former fourth-round selection in 2021 out of Texas A&M University has gone 2-0 with a 1.33 ERA (2.47 FIP) and 0.78 WHIP with 29 strikeouts and five walks in five outings (four starts). Miller was superb in his last outing on June 6 against the Detroit Tigers, when he threw six scoreless innings with only one hit allowed, two walks, and a season-high nine strikeouts. He hasn't allowed more than two runs in any of his five appearances for Seattle so far this season and appears to be fully healthy after injuries limited him to just 18 starts in 2025 in his third full year in the big leagues. Miller currently ranks in the 98th percentile in hard-hit rate, the 89th percentile in strikeout rate, and the 94th percentile in walk rate. Somehow, he's rostered in only 68% of Yahoo leagues right now. He's scheduled to make his sixth appearance of 2026 on the road in D.C. on Friday against the Washington Nationals.
