Kade Anderson Remains Elite Stash Option Despite Unclear Path to Big Leagues
Seattle Mariners left-handed pitching prospect Kade Anderson has been nothing short of dominant since making his professional debut and remains an elite stash option among all prospects ahead of Week 12 of the fantasy season. After joining the Mariners with the third overall pick in last year's MLB Draft, he was sent to the Double-A level to begin his first professional campaign. Through his first 10 outings with Double-A Arkansas, the former LSU superstar has posted an incredible 1.29 ERA with a 0.64 WHIP. During this stint, Anderson has racked up 76 punchouts while walking just seven hitters. Additionally, Anderson has allowed two runs or fewer in nine of these 10 games. However, the lone concern with his redraft value is his unclear path to the majors. With Bryce Miller back in action on the MLB roster, the Mariners have six capable starters on the roster. Despite this, Anderson's upside on a per-start basis makes him a worthy target in all formats that have N/A spots.

George Kirby Strikes Out 10 in Loss to Orioles on Wednesday
Seattle Mariners right-hander George Kirby may have taken his sixth loss of the season in Wednesday's 7-2 loss to the Baltimore Orioles at Camden Yards, but he still pitched very well for his fantasy managers. Kirby picked up a quality start by allowing three earned runs on seven hits (one homer) while walking three and striking out a season-high 10 in six innings of work. Everything was going well for Kirby through five shutout innings before he gave up all three runs on three extra-base hits in the sixth frame. He has now been handed a loss in four of his last five outings, but Wednesday's outing hopefully will help the 28-year-old turn things around after he had an ERA over 7.00 in his last four starts. After his strong outing on Wednesday, Kirby now has a 4.07 ERA on the season and 1.31 WHIP with 74 strikeouts and 21 walks in 84 innings across his 14 starts for the M's. The Orioles aren't the best matchup in baseball, but fantasy managers should be willing to roll the dice and start Kirby again for his rematch with Baltimore next week.

After Latest Dominant Outing, is Now a Good Time to Stash Kade Anderson?
Seattle Mariners pitching prospect Kade Anderson's phenomenal professional debut continued in his latest start on Friday, when he didn't allow an earned run for the third straight game after giving up just one hit in five innings of work. It was also the second consecutive game in which he did not walk a batter and struck out nine. The performance brought the left-hander's ERA down to a miserly 1.29 with a 0.69 WHIP in 49 total innings pitched, and his 39.2 percent K-BB% is the highest in all the minor leagues among pitchers who have worked at least 30 innings. After dominating Double-A competition through 10 starts, a test at Triple-A should be close at hand, and if the former third-overall draft pick has success, then a major league debut could happen later this year. Although a big league promotion is not imminent, the 21-year-old is a worthy stash consideration in deeper leagues for his high strikeout upside, especially in leagues where an NA spot is available to tuck him away in until he earns a call-up.

Bryce Miller Rediscovering Peak Form, Emerging as a Priority Waiver-Wire Target
After suffering an oblique strain in Spring Training, Seattle Mariners right-hander Bryce Miller did not make his 2026 debut until May 13. However, the 27-year-old has been impressive across 21 innings since returning to Seattle, pitching to a 1.71 ERA and 0.86 WHIP with 20 strikeouts. One of Miller's four appearances so far this season has come in relief as Seattle juggles its impressive rotation depth. Still, Miller has worked at least five innings in every outing and has also significantly out-pitched Mariners veteran Luis Castillo, with whom he is ostensibly competing for a rotation spot. Miller battled injury and underperformance in 2025, posting a 5.68 ERA across 90 innings. Early on in 2026, he looks to have regained his form from 2024, when he recorded a 2.94 ERA and 0.98 WHIP with a 17.9% K-BB rate across 180 1/3 innings. In any league where he's not already rostered, Miller should be a priority waiver wire target for fantasy managers.

Can Kade Anderson Debut During the 2026 Season?
Seattle Mariners top prospect Kade Anderson continues to showcase elite upside at the Double-A level and is seeing his value increase as a stash candidate. After joining the Mariners with the third overall pick in last year's MLB Draft, the southpaw has spent his professional career in Double-A and has looked very comfortable. Through his first nine outings with Arkansas, Anderson has logged 44 innings of work to the tune of a 1.43 ERA and a 0.75 WHIP. During this stretch, the left-hander has struck out an impressive 67 hitters while serving up just seven total walks. Additionally, Anderson has allowed one run or fewer in eight of these outings. Despite this incredible production, Anderson remains somewhat far from his MLB debut, given Seattle's pitching depth. With six capable starters on the MLB roster, the No. 6-ranked prospect in the sport will likely have to wait for several injuries or a potential trade to earn the call. However, those in leagues with N/A spots should still view the left-hander as an elite stash target given his upside on a per-start basis.

Bryce Miller a Priority Waiver-Wire Target
Seattle Mariners right-hander Bryce Miller had his 2026 season delayed by an oblique strain that he suffered in spring training. However, the 27-year-old has been effective since returning in mid-May, recording a 1-0 record with a 1.71 ERA, 0.86 WHIP, and 20 strikeouts across 21 innings (four games). While Miller made one appearance as a reliever as Seattle manages its impressive rotation depth, he's pitched at least five innings in all four of his outings. The young right-hander owns an impressive 21.5% K-BB rate that is buoyed by his elite 3.8% walk rate. After posting a 5.68 ERA across 90 1/3 innings in 2025, Miller appears to be back to the form he displayed in 2024, when he logged a 2.94 ERA across 180 1/3 innings. In any leagues where he's not already rostered, Miller should be a priority waiver wire target with upside for fantasy managers.

Kade Anderson a Top Pitcher to Stash as 2026 Debut is Increasingly Likely
Seattle Mariners starting pitching prospect Kade Anderson made his pro baseball debut less than two months ago, but he's already on the fantasy radar as a redraft stash in anticipation of his potential MLB debut later this season. Anderson was the third overall pick in the 2025 MLB Draft, making him the first pitcher off the board. Through nine Double-A starts this year, he owns a 1.43 ERA, 1.80 FIP, 13.70 K/9, 1.43 BB/9, and 0.41 HR/9. Those are incredible numbers all around, and it's even more exciting to note that he has zero earned runs and 16 strikeouts over his last two starts (10.0 innings). As a young, electric left-hander, Anderson has a spectacular outlook in dynasty fantasy baseball. However, he's getting close to being MLB-ready, and if he does get a call to the majors this year, he'll have an immediate impact in redraft leagues, too. Managers should consider stashing him in hopes that he can provide a spark in fantasy baseball during the second half of the season.

Kade Anderson Remains Elite Stash Target Amid Incredible Start to Professional Career
Seattle Mariners pitching prospect Kade Anderson continues to hold must-stash value heading into Week 10 of the fantasy baseball season. Since joining the Mariners with the third overall pick in last year's MLB Draft, the former LSU standout has looked more than comfortable in the minor leagues. The Mariners opted to send the left-hander to Double-A to make his professional debut, and he has flashed incredible potential, striking out 58 hitters over his first 38 2/3 innings. During this stretch, Anderson has posted a 1.63 ERA with a 0.80 WHIP and has allowed just seven total free passes. Removing his lone five-run outlier showing, Anderson would carry a 0.52 ERA over the first two months of the season. Even though there is no clear spot in the rotation for the left-hander, he remains on the verge of a call-up and may not need to wait long if the MLB roster needs additional depth.

Kade Anderson Reclaims Must-Stash Value After Dominant Bounce-Back Effort
Seattle Mariners pitching prospect Kade Anderson enjoyed a dominant bounce-back effort after a season-worst showing. On May 15, the former LSU superstar's near-perfect regular season came to a sudden halt as he allowed six hits and five runs, both of which set season highs. However, on May 22, the left-hander quickly returned to form, logging 4 2/3 shutout frames with three hits and a 7:2 K:BB. Removing his lone outlier outing from his game log, the former No. 3 overall pick would carry an incredible 0.52 ERA, 0.72 WHIP, and a 54:7 K:BB over a short 34 2/3 inning stint with Double-A. Given his current production, the sotuhpaw is already on the verge of reaching Triple-A and may only need a brief taste of the level before reaching Seattle. Even though there is no clear spot for him on the MLB roster, he possesses the highest upside among pitching prospects to stash, making him a priority target in all formats.

Luis Castillo Set to Start on Monday
Seattle Mariners starting pitcher Luis Castillo is set to make the start during Monday's game against the Athletics. Mariners manager Dan Wilson confirmed that Castillo will start and Bryce Miller will work behind him in a piggyback role. The Mariners tried this strategy on Tuesday, but Miller started, and Castillo worked the final few innings. Castillo tossed 2.1 innings, allowing two earned runs in the first relief appearance of his big league career. The Mariners will reverse the order in which they pitch together and hope for better results from Castillo. The veteran right-hander holds a 6.41 ERA and 1.55 WHIP, so fantasy managers shouldn't put much faith in him right now. Miller will likely pitch the bulk of the innings, so Castillo won't be a recommended fantasy option.

Bryce Miller Demoted to Bullpen Role for Monday's Game
Seattle Mariners right-hander Luis Castillo is set to start Monday's game against the Athletics. Bryce Miller will come out of the bullpen and follow in the piggyback role. Castillo has struggled this season, posting a 6.41 ERA, 1.55 WHIP, and 47 strikeouts across 46 1/3 innings. The 33-year-old struggled in his only relief appearance, taking the loss, while allowing two runs on a hit, two walks, and a HBP while striking out four over 2 1/3 innings against the Chicago White Sox. It's unclear how many innings Castillo will throw on Monday, but Miller has pitched well since returning from the injured list on May 13. The 27-year-old owns a 1.64 ERA, 1.00 WHIP, a 22.7K%, and a 4.5 BB% through 11 innings. Even though Miller is coming out of the bullpen, he's still worth holding onto in deep league formats, but can likely be dropped in 10-12-team leagues until he solidifies a spot in Seattle's rotation.

Is Kade Anderson Still the Top Pitching Prospect to Stash After Season-Worst Outing?
Seattle Mariners pitching prospect Kade Anderson remains an elite option to stash among pitchers despite his recent five-run showing. On May 15, Anderson's near-perfect start to his professional career came to a halt as he allowed a season-worst five runs and six hits to Northwest Arkansas. However, prior to this showing, the former LSU superstar was on an incredible pace at Double-A and was making a case to join the majors much sooner than anticipated. Over his first 30 frames, the lefty struck out 47 hitters while walking five batters with a dominant 0.60 ERA and a 0.67 WHIP. However, the only concern for Anderson's redraft value is his path to the majors. While his upside remains high, he has a difficult path to joining the MLB roster, pitching on a deep Seattle team that already has six proven starters on the MLB roster. Since he will likely have to wait for multiple injuries to earn the call, he is best left for 12-team leagues that have several N/A spots.

Kade Anderson Still a Must-Stash After Rough Outing?
Seattle Mariners pitching prospect Kade Anderson was the third-overall selection in last year's MLB Draft, which comes with some high expectations, but the southpaw has exceeded even that lofty outlook early on. The LSU product has struck out 51 batters in just 34 innings pitched (13.5 K/9), walking only 4.0 percent of batters he's faced (37.1 percent K-BB%), and producing a sterling 1.85 ERA through his first seven starts to his professional career at Double-A Arkansas. That pristine ERA even includes the five earned runs he yielded in his latest start; he allowed only two earned over his first six starts. Despite the rough outing, the Mariners' second-ranked prospect remains one of the top pitchers to stash in fantasy leagues. A promotion to Triple-A should not be far off, and with the expectation that the lefty will be able to compete at that level, an MLB debut should be in the cards later this season. There is not an opening in the current Seattle rotation anyway, which should give the 21-year-old some additional time to develop, but given how quickly he could get the hook to the majors and his ability to pile up the strikeouts, he should be viewed as a high-end pitcher to stash right now.

Luis Castillo Operating as Bulk Reliever on Tuesday, Should Managers Cut Ties?
Seattle Mariners right-hander Luis Castillo is slated to work as a piggyback reliever behind Mariners starter Bryce Miller on Tuesday against the Chicago White Sox, per Adam Jude of The Seattle Times. While Castillo has been one of the more dependable starting pitchers in baseball for nearly a decade, this move to the bullpen is a result of his brutal start to 2026. Across 44 innings (nine starts) so far this year, Castillo has recorded a 1-4 record with a 6.34 ERA, 1.57 WHIP, and 43 strikeouts. Miller opened 2026 on the injured list due to an oblique injury, but the combination of his return and Mariners right-hander Emerson Hancock's breakout may make it difficult for Castillo to rejoin the rotation. Even if the veteran gets another chance, his career-worst 13.4% K-BB rate could be an indicator that his time as a fantasy-relevant starting pitcher has come to a close.

Is Kade Anderson Entering Must-Stash Territory?
Seattle Mariners top pitching prospect Kade Anderson has fully put himself in must-stash territory, given his incredible start to his first professional campaign. Last year's No. 3 overall pick was sent to Double-A to begin his professional career and has been nothing short of incredible. With Arkansas, the southpaw has flashed incredible upside, logging 34 innings to the tune of a 1.85 ERA and a 0.76 WHIP. During this dominant start to his career, the left-hander has struck out 51 hitters while walking just five total batters. Over his first 30 frames, Anderson held a near-perfect 0.60 ERA before surrendering a season-high five runs in his most recent outing on May 15. The lone concern for Anderson is that the current MLB roster has a full rotation without a clear opening for Anderson. However, in the event of an injury, the former LSU superstar could get the call and become a must-start option for fantasy. For now, he is an elite stash option in all 12-team leagues ahead of Week 8.
