The Mariners could potentially be exploring looking at Bryan Woo in the bullpen before the All-Star Break.

The Seattle Mariners are coming off back-to-back disappointing losses, which resulted in a series loss.

The Mariners lost 6-5 to the Miami Marlins in extra innings Tuesday and were shut out 2-0 against the Marlins on Wednesday.

Seattle will attempt to salvage the series in the finale at 3:40 p.m. PT on Thursday at loanDepot Park in Miami.

Following the series finale, which will feature starting pitcher Bryce Miller getting the nod, the Mariners will close out the first half with a three-game series against the Tampa Bay Rays at Tropicana Field in St. Petersburg, Fla.

Seattle announced its probable pitchers ahead of the series against Tampa Bay, but it made an interesting decision ahead of the final set ahead of the All-Star Break.

The Mariners will have Luis Castillo pitch in the first game of the series Friday, Logan Gilbert pitch in the second game of the series Saturday and Emerson Hancock take the mound in the series finale Sunday.

Following the series against the Rays, the M's will next play against the San Francisco Giants on July 17 at T-Mobile Park in Seattle.

Coming out of the break, the team could be making an interesting decision as it pertains to the bullpen.

Assuming 2025 All-Star Bryan Woo gets the first start coming out of the break, that will mark 10 days between his last start, which was in the first game of the series against Miami on Tuesday.

Woo struck out five, walked one and allowed four runs (three earned) on nine hits (one home run) in five innings pitched.

Despite not getting a start in the final four games of the first half, Woo could still make an appearance.

Per an report from the Seattle Times' Ryan Divish, the Mariners could still have Woo take the mound in the first half, albeit out of the bullpen.

"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 immediate and practical impact of Woo pitching out of the bullpen seems to be to keep him fresh and stretched out before the long layoff between starts, but there could be another impact, as well.

It's been reported that Seattle could be considering bring up top pitching prospects Kade Anderson and Ryan Sloan for the bullpen in the final stretch of the season, but the team still needs spots on the bullpen for either Matt Brash or Carlos Vargas (or both) upon their return from the injured list.

Ideally, the Mariners would have a 13-man pitching staff, with five starters and eight reliable relievers for the home stretch. Based on the current construction of the roster, this would leave Sloan, Anderson, Brash, Jose A. Ferrer, Gabe Speier, Andres Munoz and Eduard Bazardo as the bullpen. This would leave one spot in the bullpen for one of the team's current six-man rotation to move to the bullpen.

Luis Castillo has been seen as the likeliest candidate to move to the bullpen due to his struggles in the first two-and-a-half months of the season. However, Woo's home-away splits could incline the team to move Woo to the bullpen.

Woo has posted a 4.23 ERA this year and has struck out 102 batters in 104.1 innings pitched across 18 starts. He has a 2.10 ERA and has allowed an opposing slash line of .156/.195/.222 in 51.1 innings of work at T-Mobile Park. On the road, he's put up a 6.28 ERA and has allowed an opposing slash line of .295/.333/.461 in 53 innings of work.
