Kade Anderson a Key Waiver-Wire Target for Final Stretch

Seattle Mariners starting pitcher Kade Anderson was called up to make his MLB debut two weeks ago. His three starts since the call-up haven't been otherworldly, but he still has the strikeout upside necessary to make him an impactful starting pitcher in fantasy baseball for the final stretch of the season. Anderson has a 5.40 ERA through his three starts, but the 3.17 FIP doesn't look quite as bad. The ball-in-play metrics are solid, but we'd like to see him harness his strikeout, walk, and home run rates over a larger sample size. His 6.60 K/9 rate in the majors is essentially half of his rate from the minors this year, and his 4.20 BB/9 and 1.80 HR/9 rates are both key reasons why his ERA is so high. Getting called up midseason could be the main reason why Anderson has been a little shaky in the majors, and we have no concerns about his ability to produce long-term. Meanwhile, in the short-term, there's still a window for him to turn things around if he can attack the strike zone and miss more bats. He's an intriguing stash in September because if he makes those corrections, he'll have a huge fantasy baseball impact. He currently ranks as the #30 starter in RotoBaller's latest rest-of-season fantasy baseball rankings.

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.

Kade Anderson Has League-Winning Upside

Seattle Mariners pitching prospect Kade Anderson will make his major league debut on Saturday against the Chicago Cubs, and the left-hander is talented enough to win leagues for fantasy managers. Anderson was called up from Double-A Arkansas to make his start on Saturday, and he did nothing to disappoint while with the Travelers. He compiled a 10-1 record with a 1.06 ERA and 0.64 WHIP to go with 135 strikeouts in 93 1/3 innings pitched. The top overall prospect for the Mariners, Anderson is considered one of the best pitching prospects in all of baseball. The 22-year-old boasts a 60-grade fastball and changeup combination to go with a 55-grade curveball and slider. The 2025 first-round draft pick rose through the minors seemingly easily to make his MLB debut, and he has the stuff to reward fantasy managers who stashed him.

Kade Anderson is a Must-Add Ahead of Season Debut

Seattle Mariners top pitching prospect Kade Anderson is scheduled to make his season debut against the Chicago Cubs on Saturday. Anderson has earned a late-season call-up after posting fantastic numbers during his lone season in the minor leagues. The Mariners selected Anderson as the third overall pick during the 2025 June Amateur Draft. During his first year in Double-A Arkansas, Anderson posted a 1.06 ERA, 0.64 WHIP, and a 135/13 K/BB ratio across 93.1 innings of work. The 22-year-old is clearly ready to be promoted above Double-A, but the Mariners feel he's ready for the big leagues after 18 starts in the minors. Given his numbers, Anderson is a must-add player ahead of his big league debut versus the Cubbies on Saturday.

Kade Anderson to Make MLB Debut on Saturday

According to Jeff Passan, the Seattle Mariners are expected to call up top pitching prospect Kade Anderson to start Saturday's game against the Chicago Cubs. The Mariners selected Anderson with the third overall pick during the 2025 June Amateur Draft. The 22-year-old has been outstanding during his lone season in the minor leagues. Across 18 starts, Anderson holds a 1.06 ERA, 0.64 WHIP, and a 135/13 K/BB ratio in 93.1 innings of work with Double-A Arkansas. The Mariners have been sliding in the standings recently, so they hope Anderson can give them a much-needed boost. Given his stats in the minors, Anderson is looking like a must-add in all fantasy formats over the final six weeks of the regular season.

Kade Anderson a Must-Stash with Clear Path to MLB Innings

Seattle Mariners pitching prospect Kade Anderson's dream season continued in his latest start this past Friday, allowing zero earned runs for the fourth consecutive contest and the 13th time in 18 total starts. The performance lowered his season-long ERA to a miserly 1.08, with a 0.64 WHIP, and an elite 36.6 percent K-BB%. All of those statistics, along with his 135 strikeouts and 13.67 K/9, are all the best in the minors among pitchers with at least 60 innings pitched. The former third-overall draft pick is positioned to debut in the majors in the coming weeks, with Mariners president of baseball operations Jerry Dipoto confirming that the lefty will be a starter, not a reliever, whenever the team decides the time is right to call him up. At this point, it looks like he'll make the leap to the majors straight from Double-A, and it could be soon, with Bryce Miller struggling mightily over his last six starts (6.12 ERA, 1.52 WHIP, 7.6 K-BB%). Anderson should be considered the top pitcher to stash in all redraft leagues for the stretch run.

Kade Anderson Has Clearer Path to Majors Amid Big-League Struggles

Seattle Mariners pitching prospect Kade Anderson has a lights-out resume this season at Double-A Arkansas, and it turns out that with Bryce Miller struggling in Seattle, he now has a clearer path to a spot in the big-league rotation. Anderson is 10-1 at Arkansas with a 1.13 ERA and 0.65 WHIP with 128 strikeouts in 87 2/3 innings pitched. The video-game-like numbers are impressive, and at age 22, Anderson has done everything in his power to prove he is major-league ready. The only question mark is the fact that he has yet to pitch at Triple-A and prove himself at the last stop before the MLB. However, the Mariners' top prospect looks more and more ready each time he pitches, and in his last outing he gave up three hits and no walks in 5 1/3 innings with nine strikeouts on the way to a win. Now is the time to stash Anderson in redraft leagues, as his time looks like it's coming soon.

Kade Anderson Extends Shutout Streak as Incredible Debut Season Progresses

Seattle Mariners starting pitching prospect Kade Anderson tossed another shutout in his most recent outing at Double-A and remains the most dominant pitcher in the minor leagues. On August 7, Anderson tossed 5 1/3 innings, allowing just three hits, with no walks, no runs, and nine punchouts. This extended his current shutout streak to 15 innings (three starts). During this stretch, the former LSU star has posted a 0.47 WHIP with a near-perfect 20:2 K:BB. On the season, the southpaw has held a 1.13 ERA with a 0.65 WHIP across his first 87 2/3 professional innings. While Luis Castillo's move to Chicago did make Anderson's path to the majors clearer, the team has indicated he will remain a starter once promoted, so he may need to wait for another injury, as Seattle currently has a full staff. However, his upside on a per-game basis remains elite, and managers should continue to view him as a priority stash option across all league types.

Path To MLB Innings Exists for Kade Anderson Following Trade Deadline

Seattle Mariners pitching prospect Kade Anderson has been lights-out all season long at Double-A Arkansas, and following the big-league club's trade of Luis Castillo at the deadline, there could be room for the talented left-hander in Seattle. Anderson has a 9-1 record this season with Arkansas and a 1.20 ERA and 0.66 WHIP. He also has 119 strikeouts in 82 1/3 innings for an extremely enticing strikeout rate. Anderson, now 22 years old, is the No. 1 prospect in the Mariners' system and boasts a 60-grade fastball and changeup with a 55-grade curveball and slider. Anderson looks like a great late-season stash in all fantasy leagues, and his upside is extremely high with his minimal ERA and WHIP coupled with his elite strikeout rate. The only question is whether the Mariners take a chance and call up Anderson to the big leagues.

Kade Anderson Will Work as a Starter Once Called Up

Seattle Mariners President of Baseball Operations Jerry Dipoto said that top pitching prospect Kade Anderson will be part of the team's starting rotation once he's called up to the big leagues, per Adam Jude of The Seattle Times. Jude reports that Anderson is expected to be promoted from Double-A Arkansas "in the coming weeks." Anderson is widely considered to be one of the top prospects in all of baseball and has put together a dominant season in the minor leagues. Across 82 2/3 innings (16 starts), the young left-hander has recorded a 9-1 record with a 1.20 ERA, 0.66 WHIP, and 119 strikeouts. He's posted an absurd 40.5% strikeout rate with just a 4.1% walk rate. Once Anderson gets called up, he offers serious upside for fantasy managers.
