Woo (11-7) allowed one run on one hit and two walks while striking out seven over seven innings to earn the win Friday over the Athletics.
Woo gave up a solo shot to Brent Rooker in the first inning, but that was the extent of the damage. Woo followed that with 6.1 no-hit innings in one of the most dominant starts in an already impressive campaign. The 25-year-old has surrendered just six runs over 26 innings across his four starts in August. Overall, he's at a 2.94 ERA, 0.94 WHIP and 160:30 K:BB through 159 innings over 25 starts. The right-hander is projected for a tough home start versus the Padres next week.

Mariners' Bryan Woo: Bounces back Tuesday
Rotowire
Woo (9-6) allowed one run on two hits and struck out nine without walking a batter over seven innings to earn the win Tuesday over the White Sox.
While one of the two hits he allowed left the yard -- a solo shot from Lenyn Sosa in the first inning -- Woo was otherwise excellent to bounce back from giving up five runs in his last start. His nine strikeouts Tuesday also matched his season high, while it was the first time since May 24 versus the Astros that he was able to avoid issuing a walk. Woo is now at a 3.02 ERA, 0.94 WHIP and 136:25 K:BB through 140 innings over 22 starts this season. He is projected to make his next start at home versus the Rays.

Mariners' Bryan Woo: Yields four homers in loss
Rotowire
Woo (8-6) took the loss Wednesday against the Athletics, allowing five runs on eight hits and one walk while striking out six batters over 6.1 innings.
Though Woo completed at least six innings for the 21st consecutive time to begin the campaign, this was far from a strong outing. He tied a season-worst mark by allowing five runs and doubled his previous season-worst tally by surrendering four homers. All of the long balls were solo shots, so Woo was at least able to keep his team in the game. Woo hasn't earned a win in any of his past four starts, posting a mediocre 4.56 ERA despite a strong 1.01 WHIP during that span. He'll try to get back in the win column in his next start, which lines up to be a home matchup against the White Sox.

Mariners' Bryan Woo: Steady in no-decision
Rotowire
Woo allowed two runs on four hits and two walks while striking out six over six innings in a no-decision versus the Angels on Friday.
Woo allowed a two-run double to Jo Adell in the first inning but settled in from there. While he went a third start in a row without a win, Woo was able to bounce back pretty well after getting tagged for five runs (four earned) over six innings in his last start versus the Astros. The right-hander continues to be one of the steadiest innings-eating pitchers in the majors -- he still has yet to have a start shorter than six innings this season. He's maintained a 2.91 ERA, 0.95 WHIP and 121:24 K:BB across 126.2 innings over 20 starts. His next outing is projected to be on the road versus the Athletics next week.

Mariners' Bryan Woo: Flirts with no-hitter Thursday
Rotowire
Woo took a no-decision Thursday against the Yankees, giving up two runs on two hits and two walks in 7.1 innings. He struck out five.
It was a brilliant performance in the Bronx from Woo, who twirled seven hitless innings to begin his evening and retired 20 consecutive batters at one point before running into some trouble in the eighth. The right-hander has proven to be as reliable as any starter in the league in the first half, spinning at least six frames in 18 straight outings. Woo boasts a 2.75 ERA, 0.93 WHIP and 109:21 K:BB across 114.2 innings, and he's provided plenty of stability to a Seattle rotation hit hard by injuries.

Mariners' Bryan Woo: Strikes out nine in no-decision
Rotowire
Woo did not factor into the decision in Saturday's 3-2 extra-inning loss to the Rangers, allowing two unearned runs on five hits and two walks with nine strikeouts over six innings.
Woo allowed a homer following a two-out error in the third inning but was otherwise excellent, throwing 61 of 97 pitches for strikes and generating 18 whiffs. The 25-year-old will wrap up June with three consecutive quality starts and has impressively completed at least six frames in all 16 of his outings this season. He'll carry a 2.93 ERA, 0.97 WHIP and 96:17 K:BB across 101.1 innings into a favorable matchup versus the Royals next week.

Mariners' Bryan Woo: Falls to Baltimore
Rotowire
Woo (5-3) took the loss Thursday against the Orioles, allowing four runs on four hits and two walks over six innings. He struck out six.
Woo got off to a nice start Thursday, holding Baltimore to one run on just two hits through his first five innings. However, things would unravel in the sixth when Woo gave up three runs on back-to-back homers by Adley Rutschman and Gunnar Henderson. Woo's been hurt by the long ball recently -- he's given up four homers over 12.2 innings in his last two outings. Overall, the 25-year-old right-hander's ERA sits at 3.07 with a 0.96 WHIP and 69:11 K:BB across 12 starts (76.1 innings) this season.

Mariners' Bryan Woo: Gives up two homers Friday
Rotowire
Woo allowed three runs on six hits and a walk while striking out three over 6.2 innings in a no-decision versus the Twins on Friday.
The 12-6 extra-inning loss was a product of a bullpen meltdown. Woo wasn't at his best Friday, allowing multiple home runs for the first time in his 11 starts this season, but he left with a lead in the seventh inning. The 25-year-old right-hander is now at a 2.82 ERA, 0.95 WHIP and 63:9 K:BB across 70.1 innings. Woo's spot in the rotation is secure, so he won't be threatened by the return of Bryce Miller (elbow), who will start Saturday. Woo's next start is projected to be at home versus the Orioles.

Mariners' Bryan Woo: Suffers tough-luck loss
Rotowire
Woo (5-2) took the loss against the Astros on Saturday, allowing two unearned runs on nine hits and no walks while striking out five over six innings.
Woo allowed two unearned runs in the first inning, one stemming from his own error, but bounced back with five scoreless frames. The 25-year-old has now gone three straight starts without issuing a walk and has delivered quality starts in eight of 10 outings this season. He'll take a 2.40 ERA, 0.93 WHIP and 60:8 K:BB across 63.2 innings into a home matchup with the Twins next weekend.

Mariners' Bryan Woo: Hit by foul ball, should start Saturday
Rotowire
Mariners manager Dan Wilson said that Woo remains on track to make his next scheduled start Saturday against the Astros after being struck in the lower leg by a foul ball Thursday, Shannon Drayer of SeattleSports.com reports.
A hard-hit foul ball in the eighth inning of Thursday's game in Houston traveled into the Seattle dugout and struck Woo, who headed back to the clubhouse for further evaluation. According to Wilson, Woo sustained some bruising to his leg, but the Mariners don't believe the issue will put the right-hander's next turn through the rotation in jeopardy. Through nine starts this season, Woo has gone 5-1 with a 2.65 ERA, 0.87 WHIP and 55:8 K:BB across 57.2 innings.

Mariners' Bryan Woo: Gets back in win column
Rotowire
Woo (5-1) allowed a run on five hits and struck out five without walking a batter over seven innings to earn the win Sunday over the Padres.
Woo turned in another fantastic outing, with the lone run coming early on a Fernando Tatis solo shot to lead off the bottom of the first inning. Woo has allowed one run or fewer in five of his nine outings this season, and this was his seventh quality start. It was also the third time in four starts in May he hasn't issued a walk, as he continues to dominate with control. Woo is at a 2.65 ERA, 0.87 WHIP and 55:8 K:BB through 57.2 innings this season. His next start is projected to be on the road versus the Astros.

Mariners' Bryan Woo: Stellar in win over Rangers
Rotowire
Woo (4-1) allowed one hit and struck out eight without walking a batter over 6.1 scoreless innings to earn the win Friday over the Rangers.
Woo retired the first 14 batters he faced and ended with 64 of 87 pitches landing for strikes in the dominant outing. This was his fourth straight quality start and his fifth such performance in six starts overall. Woo has a 2.58 ERA, 0.83 WHIP and 38:7 K:BB over 38.1 innings. He showed plenty of potential over 121.1 innings in 2024, and he's arguably been even more reliable in 2025, which is especially valuable for a rotation missing George Kirby (shoulder) and Logan Gilbert (elbow). Woo's next start is projected to be a road outing versus the Athletics next week.

Rotowire
Woo (3-1) earned the win Thursday over the Red Sox, allowing two runs on three hits and a walk over six innings. He struck out eight.
It was another strong effort from Woo, who set a season-high with eight strikeouts while recording his fourth quality start in five outings. The right-hander's ERA is down to 3.09 with a 0.97 WHIP and 30:7 K:BB through 32 innings this season. Woo will look to keep rolling in his next start, currently slated for next week against the Angels.

Rotowire
Woo (9-3) allowed three hits and a walk while striking out eight over five shutout innings to earn the win over the Athletics on Friday.
Woo kept a scoreless line for the first time since Aug. 14 in his final start of the season. The 24-year-old had seven scoreless starts in 22 outings this season, establishing himself as a high-end starter with an emphasis on elite control in his second major-league campaign. He ends the year with a 2.89 ERA, 0.90 WHIP and 101:13 K:BB over 121.1 innings.

Mariners' Bryan Woo: Fades in sixth inning
Rotowire
Woo allowed four runs on seven hits and a walk while striking out four over six innings in a no-decision versus the Rangers on Sunday.
Woo was cruising until the sixth inning. He then gave up four runs, including a three-run home run by Wyatt Langford, on five hits and a walk in that frame, and the Mariners' bullpen couldn't maintain the lead over the late innings. There's some signs of fatigue for Woo -- he's allowed four or more runs in three of his last five starts after doing that just once in his first 16 games this year. He's still at a 3.02 ERA, 0.90 WHIP and 93:12 K:BB over 116.1 innings across 21 starts. His final start of the regular season is projected to be at home versus the Athletics.

Mariners' Bryan Woo: Pummeled for seven runs
Rotowire
Woo (8-3) took the loss Tuesday against the Yankees, allowing seven runs on nine hits and a walk while striking out seven over 4.2 innings.
Woo had his worst outing of the season, tying his season-high in hits allowed and setting a new high for runs allowed while failing to reach five innings for the first time since July 27. The Yankees got to him for a pair of runs in the first and second innings before Juan Soto and Jasson Dominguez went deep in the fourth and fifth, respectively, to add on another three runs. Woo still struck out seven, tying his season high, and he had 20 whiffs on the evening. He'll carry a 2.85 ERA, 0.88 WHIP and 89:11 K:BB in 110.1 innings into a meeting with the Rangers over the weekend.

Mariners' Bryan Woo: Has no-hitter broken up in seventh
Rotowire
Woo (8-2) picked up the win over the Padres on Wednesday, allowing two runs on two hits and one walk over 6.2 innings while striking out five.
Woo had a no-hitter going through the first six frames before giving up a solo homer to Fernando Tatis with one out in the seventh. The right-hander would then be relieved by Troy Taylor with two outs in the inning, though the former would still come away with his third win in his last four decisions. Woo has also produced quality starts in six of his last eight outings while posting a robust 45:4 K:BB over that stretch. On the downside, he's now surrendered at least one long ball in five consecutive starts.

Mariners' Bryan Woo: No help in loss
Rotowire
Woo (5-2) allowed two runs on two hits, two walks and a hit batsman while striking out five over 6.1 innings to take the loss versus the Dodgers on Monday.
Woo didn't allow a run to advance past first base over his first six innings, but Gavin Lux tagged him for a solo home run in the seventh. It was still a fourth straight quality start for Woo, who has allowed a total of five runs over 27 innings through four starts in August. He's now at a 2.12 ERA, 0.83 WHIP and 61:9 K:BB through 80.2 innings over 15 starts this season. He's projected for a home start versus the Giants this weekend.
Woo came away with a no-decision in Wednesday's 3-2 extra-inning loss to the Tigers, scattering four hits over seven scoreless innings. He struck out six without walking a batter.
The right-hander put together another brilliant performance, generating 29 called or swinging strikes among his 85 pitches, but Woo wound up settling for his third straight quality start and seventh of the season when his bullpen couldn't get the job done. Through three outings in August, he's delivered a 1.31 ERA, 0.73 WHIP and 19:1 K:BB through 20.2 innings, and he seems fully recovered from the hamstring issues that began bothering him in late June. Woo will face a tough test in his next start, which is scheduled to come on the road early next week against the Dodgers.

Mariners' Bryan Woo: May need another rehab start
Rotowire
Woo (hamstring) threw 45 pitches and allowed two runs on a hit with two walks and two strikeouts over 2.2 innings during his rehab start with High-A Everett on Saturday, Daniel Kramer of MLB.com reports.
The 24-year-old rejoined the Mariners on Sunday, but manager Scott Servais was non-committal on whether the right-hander will require an additional rehab outing. The club wants Woo to be able to cover at least four or five innings before being reinserted into the big-league rotation, so it wouldn't be surprising if he's sent on another rehab outing to further build up his workload before being activated.
