Mariners continue rolling as 4-3 win clinches series in Boston

The Seattle Mariners complete a successful nine-game road trip, by making it three series wins out of three after beating the Boston Red Sox.

The Seattle Mariners’ disappointing 3-7 start to the 2025 season was punctuated by a disappointing sweep in San Francisco, bringing back memories of last season when they had a losing record on the road for the first time in four years. As a result, there was plenty of trepidation ahead of the three-game road trip to Cincinnati, Toronto and Boston.

As it turned out though, these concerns proved irrelevant as the Mariners ended up going 6-3 and winning all three road series. Making this run even more impressive, was that each time they fell a game behind before rebounding, to highlight their mental resolve.

The final stop in Boston was targeted as arguably the toughest task of all, against a Red Sox team which seems finally ready to genuinely challenge again after three years without postseason baseball. However, even Alex Bergman and company couldn’t handle the freight train that is the Seattle Mariners these days, with the series being clinched with a tense 4-3 win in the rubber match.

Bryan Woo leading the Mariners rotation

At the heart of the victory on Thursday was Bryan Woo, who has arguably been the Mariners’ most consistent starter so far in 2025. Yes Logan Gilbert might have the lower ERA, FIP and WHIP, but Woo has four quality starts in his five outings, while no one else in the rotation has more than one.

Woo was the Mariners’ best starter by the conclusion of last year and he has mostly continued in the same vein so far this season. He pitched an efficient 6.0 innings at Fenway Park, throwing a season-high eight strikeouts and matching his low of three hits.

The only player who really gave Woo any issues was unsurprisingly Bregman, who had two hits and two RBI off the righty. In general though there’s no getting away from the reality this was an excellent outing for a pitcher who is theoretically meant to be number five in the Mariners’ ideal rotation.

When Woo departed the Mariners had a 4-2 lead, but things got a little tighter in the bottom of the eighth following a solo home run by Carlos Narvaez. However, the embattled Trent Thornton got some much-needed confidence when it came in to face Bregman and subsequently forced the out to end the inning.

With the Mariners unable to add onto their 4-3 advantage in the top of the ninth, it came down to that man Andrés Muñoz to seal the deal. And seal it he did, as he continued his remarkable stretch of no earned runs allowed in 2025, and making it a perfect 9-for-9 in save opportunities.

Dan Wilson praises the pitching

Mariners manager Dan Wilson was of course happy with the efforts of Woo and the rest of the pitching staff in the series finale. As per Molly Burkhardt of MLB.com, he said:

“We didn’t really let them up for air and we got enough in early, so that our pitching was able to hold onto and just a great way to cap off the road trip.”

Turning to the Mariners’ lineup, they have experienced an offensive renaissance ever since Randy Arozarena led the stunning comeback from 5-0 down to beat the Houston Astros 7-6. Since then the team has been almost galvanized, in turn helping the Mariners win five straight series.

Mariners get to Garrett Crochet early

There were those who understandably believed the Mariners would struggle against Garrett Crochet in Thursday’s rubber match. Instead they were more than a match for the southpaw, as he ended up having career highs of five walks and 110 pitches in his 5.0 innings of action.

Most importantly though Crochet gave up four earned runs. Mitch Garver got things going with a two-run double in the top of the first, followed by RBIs from AL Player of the Week Dylan Moore and Julio Rodríguez in the second inning.

Wilson shared his thoughts on what the Mariners did to unsettle Crochet and get him out of his gameplan. He said:

“Our guys were making him work, that’s what they do. They’re patient, but when they get their pitch, they’re aggressive. And he wasn’t in the zone early, got some guys on base that kind of made it worse, but they just continued to put up their at-bats and do what they do and get some key hits when we needed them and [were] able to hang onto the lead.”

Productive offense throughout the road trip

In respect of this philosophy at the plate, Wilson discussed what the lineup was able to achieve during the nine-game road trip as a whole. He said:

“I think we were able to hit some home runs in Toronto, we hit some home runs in Cincinnati and here we’ve been able to get runners on base like last night. We’re gonna grind out at-bats, we’re going to be tough at-bats all game long and that’s what our identity is.”

It will be interesting to see how the Mariners continue to perform offensively as they move forward. Their batting average on the season at the time of writing is only 22nd, while there is the ongoing issue of how playing at T-Mobile Park impacts them.

At the same time however, the Mariners are still proving to be extremely productive as evidenced by being tied-10th in the majors in OPS and — most importantly — 10th in runs scored. They will now prepare for a weekend series back home in Seattle against the Miami Marlins and leading the AL West ahead of Friday’s opener.
