The Mariners may be staring at a bullpen wrinkle before the All-Star break, and Bryan Woo is right in the middle of it.
Seattle has dropped two straight to the Miami Marlins, first a 6-5 extra-inning loss on Tuesday and then a 2-0 shutout on Wednesday, and will try to avoid a series defeat in Thursday’s finale at 3:40 p.m. PT at loanDepot Park. Bryce Miller is scheduled to start that game.
After that, the final stretch of the first half sends the Mariners to Tropicana Field for three games against the Tampa Bay Rays. Seattle has already laid out its probable pitchers for that series: Luis Castillo on Friday, Logan Gilbert on Saturday and Emerson Hancock on Sunday.
Then comes the break, and that’s where things get interesting.
If Woo gets the first start after the All-Star break, he would be working with 10 days between outings after starting the opener of the Miami series on Tuesday. In that outing, the 2025 All-Star struck out five, walked one and gave up four runs, three earned, on nine hits, including one home run, over five innings.
That gap has opened the door for a possible bullpen appearance before the break, even though he is not scheduled to start again in the final four games of the first half.
“I think it’s something that we’ll look at, especially because he’ll have such a long layoff,” manager Dan Wilson said in Divish's article. “It might be advantageous for him to get out on the mound a little bit and throw.
But the right situation would have to present itself. We’d have to look at it as we go, but we certainly wouldn’t rule it out at this point.”
The most obvious reason for using Woo out of the bullpen would be simple enough: keep him fresh and stretched out before that long break between starts. But there’s another layer here, too.
Seattle has also been linked to the idea of bringing up top pitching prospects Kade Anderson and Ryan Sloan for bullpen work down the stretch, and the roster math gets tight once Matt Brash or Carlos Vargas, or both, return from the injured list.
The ideal setup for the Mariners would be a 13-man pitching staff with five starters and eight dependable relievers. Under the current structure, that would leave Sloan, Anderson, Brash, Jose A. Ferrer, Gabe Speier, Andres Munoz and Eduard Bazardo in the bullpen, which creates room for only one current member of the six-man rotation to shift into relief.
Castillo has looked like the most obvious candidate for that move because of his struggles over the first two and a half months of the season. But Woo’s home-away splits could also push Seattle to consider him for that role instead. After the Rays series, the Mariners return to action against the San Francisco Giants on July 17 at T-Mobile Park.

Mariners Dream Deadline Bat Comes With One Huge Catch
As the trade deadline draws closer, the Mariners are still looking for a lineup upgrade that can give their offense a better chance to carry them deeper into the season. ESPNs Jeff Passan recently pointed to Orioles outfielder Taylor Ward as the clubs best fit, citing the kind of on-base ability and walk rate Seattle has been chasing as it tries to add more traffic for the middle of the order.
The more intriguing name in the discussion is Red Sox first baseman Willson Contreras, who has been swinging a hot bat and would certainly change the look of the Mariners attack. The catch is obvious enough: Seattle would have to sort through an already crowded first-base and DH picture, which would put even more pressure on Dan Wilson to find playing time for everyone if the front office decides to push for a bigger splash.

Jerry Dipoto May Be Setting Up An Unusual Mariners Deadline Move
Jerry Dipoto is signaling that this deadline may not follow the usual seller-and-buyer script, with the Mariners executive suggesting more contender-to-contender deals could emerge because so many teams in the race have real needs to fill. For Seattle, the list is familiar: a left-handed bat and bullpen help remain priorities, and especially a high-leverage reliever if the market lines up right.
The wrinkle is that the Mariners also have pieces other contenders want, particularly starting pitching depth and left-handed bats, which could make them both shoppers and suppliers in the same week. ESPNs Jeff Passan said those kinds of deals are complicated to build, and he pointed to the possibility of Seattle using its prospect capital in the right kind of swap, a setup that would fit the kind of deadline move Dipoto has been willing to chase before.
