MLB: Mariners Down Astros for Biggest Series Win of the Season

8/16/26

(Houston, TX) Pretty much every series from here on out will be classified as a big series for the Seattle Mariners but the three-game set over the weekend was bigger than big. With a chance to take matters into their own hands and cut into their AL West deficit, the Mariners would need to treat this weekend as a playoff series. A series loss would be disaster and put them at least six games back in the division while a series win would cut it down to just four.

That is because the Mariners traveled to take on the Houston Astros for three games in their final trip to the Lone Star State this regular season. While the M’s have had a very difficult time in Arlington, Houston has been a different story. Dating back to last season, the M’s have won 6 of the last 7 in Houston and 10 of the last 11 overall with the Astros. The two teams taking the field this weekend were very different as the M’s could not have lower morale while Houston saw the opportunity to potentially bury one of the teams in the division trying to chase them down.

Astros 10, Mariners 7 (10 Innings) (Game One, August 14th)

The series began on Friday night with both teams looking to start the weekend off right and take control of the set themselves. For the pitching matchup, George Kirby would have the ball for the Mariners, looking to build upon his strong start to August. For the Astros, Peter Lambert would get the start and he entered Friday as the most reliable starter on the Houston roster so far in 2026.

Seattle would do something they haven’t done too much of on the road this season and that is get off to a fast start. In the top of the 1st, Randy Arozarena recorded the first hit of the game with a one-out double for his 25th double of the season. The very next batter would be Dominic Canzone and he roped a base hit to right to put the Mariners up 1-0 just three batters into the game. That was not all for the M’s as Julio Rodríguez doubled for the 17th time this season and Josh Naylor cashed in with a sacrifice fly to give Seattle a 2-0 lead before George Kirby ever took the mound.

It was not just the Mariners getting off to a hot start. Houston would also get a run on the board in the 1st and it came off the bat of the likely American League MVP winner. With the bases empty and one out, Yordan Alvarez continued his quest for the Triple Crown, boosting his home run and RBI total in one swing. Alvarez destroyed a changeup, hitting it 368-feet for his 36th home run of the season. The AL leader in homers had another as he got Houston on the board with Seattle still leading 2-1.

George Kirby did not seem to let that home run rattle him as he retired the next four Astros he faced to keep the bases empty with two outs in the 2nd. Then things unraveled quickly for the righty. Christian Walker hit a harmless single before Cam Smith did more damage with his third triple of the season to score Walker and tie the game at 2-2. It didn’t stay tied for long as Christian Vázquez walked before a Jeremy Peña single put Houston out in front. The Mariners elected to intentionally walk Yordan Alvarez but it didn’t pay off as Isaac Paredes came through with a two-run single. Houston put up four runs all coming with two outs to take a 5-2 lead.

Things settled in after that with Houston loading the bases with two outs in the 5th when the Mariners had to go to their bullpen and Michael Rucker got a grounder to end the threat. Seattle would get to Houston’s bullpen right away when lefty Bennett Sousa gave up a double to Josh Naylor to begin the 6th. He moved up to third but was still there with two outs when Victor Robles clutched up in Houston again. A base hit to left brought in Naylor and chipped away at the deficit with a 5-3 score.

Michael Rucker retired all four batters he faced and Gabe Speier also pitched a 1-2-3 7th to keep it a two-run game into the 8th. Bryan Abreu was in for the 8th. He would walked J-Rod who turned it into a double with his 16th stolen base of the season. Josh Naylor moved him to third with a groundout before Brendan Donovan brought him home with an RBI groundout to make it 5-4. Cal Raleigh kept the inning alive with a walk before Victor Robles reached on a bunt single. With two on and two outs, rookie Brock Rodden came to the plate and chose a great time for his first career hit. A double bounced into the seats as his family celebrated in the stands as Rodden tied the game at 5-5 late.

Seattle stranded a couple of runners in the 9th while Eduard Bazardo pitched scoreless innings in the 8th and 9th. We would go to extras with Enyel De Los Santos pitching the 10th for Houston and Brendan Donovan as the automatic runner. Victor Robles put the M’s in front with a triple to bring home Donovan and make it 6-5. The Mariners got the job done, putting up a crooked number with a sacrifice fly by Brock Rodden to make it 7-5 going into the home half of the 10th.

Andrés Muñoz pitched the bottom of the 10th to try to close it out and give the Mariners a pivotal game one win. Jeremy Peña would be the automatic runner and moved up on a groundout by Yordan Alvarez before scoring on an Isaac Paredes single to make it 7-6 with one out. Muñoz would strikeout Taylor Trammell for the second out and put the M’s in a gold spot. He quickly got two strikes on Jose Altuve and got him to chase a slider well off the plate that somehow dunked in for a single. A similar thing happened when Muñoz faced Daulton Varsho who snuck a game tying RBI single into left center. All of a sudden, the game came to a gut punching end as Christian Walker obliterated his 23rd home run of the season to left for a walk-off. Seattle was one strike away from a win twice and yet walked away with a devastating 10-7 loss in extras in the opener.

Mariners 10, Astros 5 (Game Two, August 15th)

After a gut wrenching series opener, the Seattle Mariners would hope to keep the bats hot and quiet the Houston Astros in game two on Saturday night. Emerson Hancock would have the start after a short outing at home against Tampa Bay. Opposite him would be Hayden Wesneski who was making just his fourth start of the season.

This time it was Houston getting off to a hot start in the bottom of the 1st. After Emerson Hancock retired the first batter, the next three reached with a walk to Yordan Alvarez and singles by Isaac Paredes and Daulton Varsho. With the bases loaded and one out Jose Altuve did enough to bring in a run with an RBI infield single to keep the bases loaded. Hancock minimized the damage with a couple of strikeouts but Houston had still netted a 1-0 lead early on.

Seattle immediately came back with their own offensive inning to help out Emerson Hancock a little bit. Julio Rodríguez and Josh Naylor both singled to start the inning to put runners on the corners with nobody out. Cole Young sent a bouncer that Hayden Wesneski had trouble making a play on to bring in J-Rod with an RBI infield single to tie the game at 1-1. Two batters later, Victor Robles stayed red hot with another triple, his second of the series and season, bringing home two more and putting Seattle in front. A two-out single by Brendan Donovan would score Robles and a four-run inning allowed Hancock to settle down with the M’s up 4-1.

Houston got a run back on a solo shot by Christian Vázquez for his sixth home run of the year. Things once again began to settle down offensively for both teams but only for an inning before Seattle woke back up. In the 4th, Cole Young reached with a single and Victor Robles on a walk but both remained on base with two outs. Brendan Donovan continued his nice game with a slap shot into left field to once again clutch up with two outs yet again. Seattle’s lead was back up to three at 5-2.

Despite a really tough start for Emerson Hancock, he dug his heels in and fought through his start and ended up with a strong outing this time around. A similar start as his one against the Rays, Hancock was in deep trouble early but fought through it and this time avoided trouble after that. Hancock ended up going seven innings with just those two early runs allowed while giving up five hits and two walks while striking out eight. It was a very gutsy outing for the young right-hander in a game that Seattle needed their starter to eat innings.

Seattle would open things up a bit more in the 8th. It came via a two-out rally as the bases were empty with two away when Victor Robles singled and stole second. Brock Rodden narrowly missed his first career home run with a shot off the wall in left center but did have his second RBI double of his early career. Rodden would then score on yet another two-out RBI single by Brendan Donovan to make it 7-2 M’s.

José A. Ferrer was on for the bottom of the 8th and it was a bumpy inning that got Houston back into it. A double by Jeremy Peña was followed by Isaac Paredes’ 16th home run of the season to make it 7-4. It did not really matter as a couple of singles in the 9th were followed by a Cole Young three-run blast for his 15th home run of the year to make it 10-4. Houston got one in the bottom of the 9th but the Mariners bats exploded in this one to even up the series with a 10-5 win.

Mariners 3, Astros 2 (Game Three, August 16th)

Sunday night baseball was quite the stage for the Seattle Mariners and Houston Astros rubber game on Sunday. With the entire nation watching before going back to work the next day, Bryan Woo would hope to build upon his recent good road start in the Bronx and put his road woes behind him. It would not be easy for the M’s as the Houston Astros would have ace Hunter Brown on the hill in the middle of his worst season of his young career.

Two batters into the game and the Mariners were already feeling good. Hunter Brown retired Brendan Donovan to start the game but Randy Arozarena was ready to do some damage. He worked a 2-2 count before a fastball just above the zone was deposited into the Crawford Boxes in left for his 17th long ball of the year. Arozarena mad it three home runs on the road trip and gave the Mariners a quick 1-0 lead.

Brock Rodden and Brendan Donovan continued to be thorns in the side of the Astros in the 3rd with back-to-back walks to begin the inning. Randy Arozarena would beat out a double play ball to put runners on the corners but would be caught stealing by Yainer Díaz for a huge second out while Rodden remained at third. Celebrating his 29th birthday on Sunday, Dominic Canzone had a nice day after doubling in the 1st. This time he came through with a two-out base hit to right to bring in Rodden. Seattle’s two out hitting continued to click as they made it 2-0.

Hunter Brown completely lost feel of the strike zone in the 4th and in a span of 13 pitches, walked three batters to load them up with two outs for Brendan Donovan. The pesky Donovan battled to a 2-2 count before taking a close pitch for strike three to end the threat and he elected to not use one of the two challenges the Mariners had. That momentum built for Houston in the 4th as Jeremy Peña went deep for his 14th home run of the season. What felt like an opportunity for a knockout shot for the Mariners turned into the Astros getting back into the game at 2-1.

Hunter Brown was done after five innings as the M’s allowed him off the hook on his five walks issued. Bennett Sousa was the first man out of the Houston bullpen for a lefty-lefty matchup with Josh Naylor that resulted in a base hit. Naylor would steal second as Cole Young struck out but was then thrown out trying to steal third to clear the bases with two outs. Cal Raleigh was at the plate and hit a towering fly ball out to left that would have been a fly out in any other ballpark other than Daikin Park. In Houston however it was the Big Dumper’s 13th home run of the season. Seattle would take what they could get and took a 3-1 lead.

Houston got that run right back on a Nick Allen leadoff homer for his second of the season to make it 3-2. The M’s would leave the bases loaded again in the 7th as Bryan Woo was done after six quality innings with just two solo homers allowed. Houston would put some pressure on Gabe Speier in the 8th on a two-out single by Yordan Alvarez but in a big move, Houston removed Alvarez from the game and put Cam Smith in as a pinch runner representing the tying run. Isaac Paredes then singled before Dan Wilson brought in Seranthony Domínguez to face Jose Altuve. Altuve put the first pitch in play with a little pop-up on the infield, but Domínguez fell down moving backwards as the ball dropped for an infield hit to load the bases. Daulton Varsho came to the plate with bases loaded and two outs but Domínguez won the battle with a strikeout to escape the jam and protect the Mariners lead.

Randy Arozarena led off the 9th with a double and despite Julio Rodríguez hitting a ball 413-feet, the M’s could not add on and kept a 3-2 lead into the bottom of the 9th. Andrés Muñoz was hoping for some redemption after a blown save on Friday and got immediate revenge on Christian Walker with a soft groundout. He would then put the tying run on via a walk to LaMonte Wade Jr. but bounced back with a strikeout of Yainer Diaz. With one out to get, Andrés Muñoz was not missing this opportunity and sat down former teammate Taylor Trammell to slam the door shut. It was a huge series win for the Mariners as they bounced back from a devastating loss in game one to take the series with a 3-2 win in the rubber game.

What’s Next

This is the biggest series win for the Seattle Mariners (59-66) all season as it gives them a little bit of momentum towards the last leg of the road trip. They cut into the AL West deficit themselves by taking care of Houston while Texas dropped two out of three to the Athletics, who moved past the Angels at the bottom of the AL West as the Halos lost two out of three to Kansas City. The Astros lead the Rangers by two games and the Mariners by four games while the A’s and Angels are both way back and out of the race. The M’s trail Baltimore for the final Wild Card by 2 1/2 games. Houston will welcome the Los Angeles Angels in their next series while Texas hosts the Washington Nationals.

Meanwhile the Mariners continue their gauntlet of an August schedule as they wrap up their nine-game road trip with a series in Milwaukee. The Brewers are the best team record wise in baseball at 77-48 and bounced back in a big way this weekend. After being swept in San Diego, the Brewers went into Los Angeles and took three out of four from the slumping Dodgers to firmly establish themselves atop the National League. Milwaukee is third in baseball in team ERA at 3.51. Milwaukee offensively does not do anything extremely well but they are pesky and put the bat on the ball and don’t have any weaknesses as a team either. The lineup is as balanced as they come and Milwaukee has become one of the most consistent teams in pro sports over the last decade.

Fortunately for the M’s, they will miss the likely NL Cy Young winner in Jacob Misiorowski. Seattle actually lucked out with the pitching matchups but things will still be very tough especially with the breakout season for former Mariner, Jake Bauers. Bauers played just 72 games for the M’s in 2021 but has shattered career highs in 2026 across the board. 21 home runs and 70 runs batted in has made Bauers a consistent middle of the order bat for Milwaukee. He hasn’t had really any super hot or super cold months but has been extremely consistent as Milwaukee has had some key players injured like Jackson Chourio and Brice Turang. They are going to score runs so the Mariners have to build upon the offensive momentum that they created in Houston.

• Game One, Tuesday 4:40pm- Bryce Miller (4-6, 3.39 ERA) vs. Kyle Harrison (9-3, 3.47 ERA)
• Game Two, Wednesday 4:40pm- Logan Gilbert (9-7, 3.28 ERA) vs. Dustin May (6-7, 4.13 ERA)
• Game Three, Thursday 11:10am- George Kirby (8-9, 3.89 ERA) vs. Robert Gasser (3-5, 4.54 ERA)
