The Seattle Mariners added another arm to the organization on Wednesday, agreeing to a minor-league deal with right-hander Simeon Woods Richardson and sending him to Triple-A Tacoma.
Woods Richardson arrives as a once-prominent prospect whose name had been sitting near the top of the pipeline for a while. MLB Pipeline ranked him among its top 100 prospects in both 2020 and 2021, and he reached the majors at 22 with the Minnesota Twins in 2022.
His big-league track record is already fairly extensive for a 25-year-old. Across parts of five seasons with Minnesota and Toronto, Woods Richardson has gone 14-17 with a 4.72 ERA and a 1.39 WHIP, striking out 272 and walking 136 over 320 2/3 innings in 73 appearances, including 61 starts.
Seattle has already seen plenty of the right-hander’s best work. In two starts against the Mariners - one in 2024 and one in 2025 - he held them scoreless over 11 innings and piled up 14 strikeouts.
This season has been a rough one overall. Woods Richardson opened the year with Minnesota and struggled through the first two months, going 0-7 with a 7.74 ERA in 12 outings, 10 of them starts. He allowed nearly as many walks, 25, as strikeouts, 26, while covering 47 2/3 innings.
Minnesota dealt him to Toronto for cash on June 3, and his stint with the Blue Jays was short-lived. He worked eight relief appearances for Toronto, posting a 3.93 ERA with 14 strikeouts and 12 walks over 18 1/3 innings. Toronto designated him for assignment on Aug. 28, and he elected free agency Tuesday after being outrighted to the minors.
A second-round pick in 2018, Woods Richardson brings a four-pitch mix built around a four-seam fastball, splitter, slider and curveball. His fastball averages 92.6 mph.

Mariners Just Created A Connor Joe Question Fans Can't Ignore
The Mariners latest roster shuffle left Connor Joe in a familiar but uneasy spot. After Seattle designated Joe and right-hander Nolan Kingham for assignment to make room for Lzaro Montes and Hoby Milner on the 40-man roster, both players cleared waivers and were outrighted to Triple-A Tacoma, keeping the move from being the end of the road for either player just yet.
Joe now has a decision to make, since he has the right to elect free agency, and the Mariners have not indicated whether he plans to stay in the organization or test the market. Kinghams path is more straightforward because his service time means he has to accept the assignment, but Joes situation is the one that lingers for Seattle, where every roster spot matters and every fringe move can hint at what comes next.

Mariners May Have Found A Better Use For Their Latest Pitching Add
The Mariners added another arm to their system by signing right-hander Simeon Woods Richardson to a minor-league deal and sending him to Triple-A Tacoma. Most of his big-league work has come as a starter, but he has also handled multiple roles this season, which makes him an interesting fit for a Seattle pitching staff that suddenly needs more flexibility.
With rotation depth thinned by an injury, the appeal here is less about where Woods Richardson has traditionally worked and more about where he might help most. Seattle can use pitching in just about any form right now, and his ability to cover innings gives the club another option if it wants to patch a game together out of the bullpen or lean on a bulk reliever while the roster sorts itself out.

Randy Arozarena Just Gave Mariners A Dangerous Reminder
Randy Arozarena spent the weekend reminding the Mariners why he changes the tone of a series so quickly. In Seattles 8-3 win over the Red Sox, he made an impact on both sides of the ball with key defensive plays and an RBI single, continuing a stretch in which he homered in the first two games and kept stacking up damage against Boston.
By the end of the series, Arozarena had six hits, two home runs, eight RBIs and four runs scored, the kind of all-around production that can tilt a lineup when it shows up at the right time. For a Mariners club trying to keep building momentum, his burst was a useful snapshot of what happens when he gets locked in, and it leaves the larger question of how long this version can keep rolling.
