    Mariners selected the contract of LHP Kade Anderson from Double-A Arkansas.

    It’s time. Anderson’s meteoric rise concludes with his major-league debut against the Cubs on Saturday following an unprecedented 18-start run at Double-A Arkansas where he compiled a microscopic 1.06 ERA, 0.64 WHIP and 135/13 K/BB ratio across 93 1/3 innings in his professional debut. The 22-year-old southpaw, who was the third-overall selection in last year’s draft, offers enough strikeout upside to be relevant in all fantasy formats over the final five weeks of the season. His signature offering is an upper-80s slider that he can consistently land in the strike zone for strikes, while also burying it below the zone to generate whiffs as a putaway pitch. It’s so early in his long-term development trajectory that fantasy managers should keep realistic expectations in check, but it’s not hyperbolic to assert that Anderson is unquestionably one of the more exciting, front-of-the-rotation caliber pitching prospects to reach the big leagues in recent memory. He’s long gone in most competitive fantasy leagues and should remain rostered until further notice.

    Anderson struck out five and walked none, but the hits he allowed came in bunches in the first and third innings. Anderson is due to make two more starts Sunday against the Rockies and then the next Saturday against the Angels. Still, with the Mariners all but out of the race, we wouldn’t be surprised if at least that last start disappears.

    As it turns out, Anderson wasn’t the cure all for Seattle’s issues. He gave up seven hits and managed just three strikeouts tonight against a lineup that had Jonah Heim batting cleanup. Anderson is almost certainly destined for big things as a major leaguer, but it’s going to take time. He’s still probably worth using in mixed leagues at home versus the Rangers next week.
  • SEA Starting Pitcher #13
    Anderson got off to an excellent start in his second career outing for the Mariners. He stranded four baserunners across four scoreless innings before getting into some trouble in the fifth. He gave up a base hit and walked a batter with one out in the inning, ending his day at 85 pitches as the team looks to limit his pitch count. Both inherited runners would come in to score. He struck out three. The 22-year-old left-hander has given up five runs with an 8/5 K/BB ratio over 10 innings across his first two starts. Anderson is in line for his third start on Thursday, taking on the Athletics in Seattle.

    Anderson tossed a clean first inning, collecting his first career strikeout on Alex Bregman to end the inning. He worked around a walk in the second inning, then tossed a clean third with the help of a spectacular home run robbery by Randy Arozarena. Anderson gave up his first hit to lead off the fourth, then surrendered his first run on a walk, a hit, and a sacrifice fly in the fifth. Despite being at 72 pitches and never having thrown more than 80 this season, he returned for the sixth, facing the order for a third time, and gave up back-to-back solo homers to Alex Bregman and Michael Busch, knocking him from the game with two outs at 81 pitches. Still, it was an impressive debut overall for the talented 22-year-old right-hander. He’ll get a chance to build on his solid first start with a matchup against the Blue Jays in Toronto next weekend.

    And the fantasy managers rejoiced. The 22-year-old southpaw will make his highly anticipated MLB debut on Saturday against the Cubs. Anderson, the third overall selection from the 2025 MLB draft, has compiled a brilliant 1.06 ERA, 0.64 WHIP and a 135/13 K/BB ratio across 93 1/3 innings in 18 starts at Double-A Arkansas this season. He should be rostered in all fantasy leagues and is expected to make an immediate impact for the M’s and for fantasy managers over the final six weeks of the season.
  • SEA Starting Pitcher #22
    Woo completed six innings in the win tonight, but he was only at 75 pitches, and it sounds like he would have continued if not for the shoulder issue getting him lifted as a precaution. Woo said after the game that he wasn’t concerned about it. Still, if he winds up on the IL, that would open up a spot for top prospect Kade Anderson. Anderson, though, should really be in the majors regardless.

    The time to stash Anderson was weeks, if not months, ago. Now, his arrival in Seattle appears imminent, especially after the Mariners jettisoned veteran Luis Castillo at the trade deadline earlier this week. The 22-year-old pitching phenom, who was selected third overall in last year’s draft, has authored one of the most dominant professional debuts in recent memory, posting a microscopic 1.13 ERA and 0.65 WHIP with a staggering 128/12 K/BB ratio across 87 2/3 innings. Seattle can promote Anderson later next week while preserving his rookie eligibility for next season. Mariners president Jerry Dipoto told reporters earlier this week that he will work as a traditional starter, and won’t pitch in relief, when he jumps to the big leagues. At this point, all signs point toward Anderson making his major-league debut next week. Simply put, he has nothing left to prove in the minors and represents a must-roster arm in all fantasy leagues.

    Seattle didn’t move on from George Kirby or Emerson Hancock at the trade deadline, but they managed to ship veteran Luis Castillo to the White Sox over the weekend, which could open up a rotation spot for Anderson. The 22-year-old top pitching prospect figures to arrive at some point in mid-August so that he’ll remain rookie-eligible for next season. He’s put together a sublime professional debut with a microscopic 1.20 ERA and 119/12 K/BB ratio across 82 1/3 innings over 16 starts for Double-A Arkansas. Needless to say, Anderson should’ve been stashed in most fantasy leagues a while ago.

    Passan adds that the sense is that Kirby is available and could be moved prior to Monday’s deadline. He also notes that Seattle has been listening to offer for Emerson Hancock and Luis Castillo. The Mariners have top prospect Kade Anderson knocking on the door of the majors and figure to move at least one, if not more, of their current rotation members. Kirby would net the largest return in any potential trade package, despite holding a pedestrian 3.98 ERA across 120 innings this season.
  • SEA Starting Pitcher
    It’s fair to wonder whether Seattle will wait until mid-August to promote Anderson since that would allow him to remain rookie-eligible for next season. There will be a rotation spot open one they move on from either Emerson Hancock or Luis Castillo ahead of next week’s trade deadline. There’s a chance that both of them are on the move. Anderson has checked every metaphorical box during his professional debut with a microscopic 1.20 ERA and 119/12 K/BB ratio across 82 1/3 innings over 16 starts for Double-A Arkansas. Needless to say, Anderson should be stashed in all fantasy formats. His time is coming.

    Nationals signed RHP Cade Cavalli to a four-year contract extension through the 2030 season with a club option for 2031.

    This was rumored to be close on Thursday and it gets done on Friday. This extension buys out one year of free agency as well as his arbitration seasons before considering the team option. Cavalli, starting tonight’s game for the Nationals, has posted a 3.12 ERA in 31 starts while striking out 194 batters over 164 2/3 innings. He’s been even better than that as of late, with a 2.83 ERA since the start of June. The 28-year-old will be a part of the Nationals rotation plans going forward and has made the leap to extremely useful fantasy pitcher this season. It’s a success for the Nationals to get him locked up for the long-term.

    Jac Caglianone is not in Kansas City’s starting lineup for Friday’s game against the Pirates.

    That makes two of the last three games on the bench for Caglianone, who may not be completely over getting beaned in the forearm on Tuesday (or his elbow injury that kept him out for much of last week) at this point. John Rave will be in there against RHP Paul Skenes.

    Adley Rutschman is not in Boston’s starting lineup for Friday’s game against the Rays.

    It appears to be a routine day off against Rays LHP Ian Seymour. Connor Wong will get the start at catcher after Rutschman played the last six games in a row.

    Brewers recalled LHP Colton Gordon from Triple-A Nashville.

    Gordon has a 4.67 ERA in 54 innings (over 10 starts) with Triple-A Nashville since coming over in the Lance McCullers Jr. trade. He’ll be an option to start or go bulk in a game down the stretch for the Brewers as they finish off a sterling regular season.

    Brewers optioned RHP Garrett Stallings to Triple-A Nashville.

    He threw three innings yesterday and was exchanged for a fresh arm in LHP Colton Gordon. Stallings has thrown 14 shutout innings in the bigs so far this year, with 17 strikeouts and just four hits allowed.

    Willson Conteras (hand) is not in Friday’s starting lineup for the Red Sox against the Rays.

    He was hit by a pitch on a swing and left the game on Thursday. X-rays came back negative, but he will likely remain day-to-day for most of the weekend. Nick Sogard is handling first base tonight while Isiah Kiner-Falefa squeezes into the lineup at second base.

    Reds recalled RHP Julian Aguiar from Triple-A Louisville.

    One Julian replaces another as Julian Garcia heads to the injured list. Aguiar holds a cringe-inducing 6.27 ERA in 12 starts for Triple-A Louisville this season, having walked 31 in 58 innings after missing 2025 to Tommy John surgery. However, he was already on the 40-man roster, so here he is, likely to handle low-leverage work in the bigs.

    Reds placed RHP Julian Garcia on the 15-day injured list, retroactive to September 17, with right elbow loose bodies.

    Elbow issues for a pitcher is never what you want to hear. This ends Garcia’s season. He had a 3.33 ERA in 46 innings with the Reds, notching two saves and striking out 41. The 31-year-old is set to be a free agent after the season. Assuming this isn’t a long-term issue, he’ll likely get a shot to compete for a bullpen spot somewhere next year.

    Reds transferred 1B Spencer Steer from the 10-day injured list to the 60-day injured list.

    Steer was unlikely to play again this season either way, and this should just about end his ability to return since he was originally placed on the injured list on July 27. It’s a procedural move to free up a 40-man roster spot for new Reds infielder Oswaldo Cabrera.

    Chase DeLauter (wrist) is batting third for the Guardians in Friday’s game against the Athletics.

    He had sat out Tuesday and Wednesday’s games. DeLauter has been quite dinged up down the stretch; he’s played in just 10 September games so far. But he has hit .243/.333/.432 when able to play, with a homer and two stolen bases. He’s safe to activate in daily transaction leagues against A’s starter Mason Barnett.
