• Mariners' Bryan Woo: Racks up nine Ks over six frames

  Rotowire Mar 29, 2026

  Woo allowed two runs on four hits and one walk while striking out nine batters over six innings in a no-decision against Cleveland on Saturday. Woo held the Guardians scoreless through five innings, but Cleveland got to him for a pair of runs in the sixth. That proved to be the right-hander's final frame, and while that sixth inning ended up costing him a chance for the win, he did notch a quality start and give fantasy managers a hearty nine punchouts. Woo tossed 59 of 83 pitches for strikes in the start and racked up a robust 15 whiffs, buoying his case to be considered among fantasy's elite starting pitchers. He's lined up to next start against the Angels on the road.

• Mariners' Bryan Woo: Reaches six innings in final tuneup

  Rotowire Mar 23, 2026

  Woo allowed one run on three hits while striking out four without a walk over six innings in Sunday's Cactus League win over the White Sox. "Extremely locked in, extremely focused, the intent he has on the mound is next to none, and it's really a big part of what he does," manager Dan Wilson said after the game regarding Woo's performance, Ryan Divish of the Seattle Times reports. Divish notes that Woo induced 11 whiffs, including six with his four-seam fastball, on 73 total pitches (52 strikes) in his fourth and final start of spring training. The pitch count sets Woo up for a relatively normal workload in his 2026 regular-season debut this weekend at home against the Guardians. He is not the ace in Seattle, and in fact it appears he will slot in behind both Logan Gilbert and George Kirby, but Woo has a case as a fantasy ace after a top-five finish among fantasy starting pitchers in his age-25 breakout last season.

• Mariners' Bryan Woo: Available in relief for Game 5

  Rotowire Oct 16, 2025

  Woo will be available out of the bullpen Friday in Game 5 of the ALCS versus the Blue Jays, Tim Booth of The Seattle Times reports. Woo had been a candidate to start Game 5, but the Mariners will instead turn to Bryce Miller for their final home game of the series. The 25-year-old Woo has not appeared in a game since Sept. 19 due to right pectoral inflammation, but he's healthy now and will give Seattle some length in relief, if needed.

• Mariners' Bryan Woo: Tentatively in line for Game 5

  Rotowire Oct 13, 2025

  Woo (pectoral) is tentatively lined up to start Game 5 of the ALCS against the Blue Jays, Adam Jude of The Seattle Times reports. Woo was not on the Mariners' ALDS roster as he works his way back from right pectoral inflammation, but he is on the ALCS roster and had a successful live batting practice session Monday that he referred to as "a huge positive." If he recovers well from live BP, it sounds as though Woo will start on Friday in Game 5, if necessary. If that happens, he will have gone nearly a month between starts, as Woo's last appearance came Sept. 19 against the Astros.

• Mariners' Bryan Woo: Included on ALCS roster

  Rotowire Oct 12, 2025

  The Mariners added Woo (pectoral) to their active roster for the ALCS against the Blue Jays, Tim Booth of The Seattle Times reports. President of baseball operations Jerry Dipoto indicated Saturday that Woo was expected to make the roster after sitting out the past few weeks due to pectoral inflammation, so it's not a surprise the right-hander is active for the championship series. The 25-year-old was Seattle's best starting pitcher during the regular season with a 2.94 ERA, 0.93 WHIP and 198:36 K:BB across 186.2 innings, but he likely won't be available to pitch for the Mariners until later in the week when the series shifts to Seattle after the first two games in Toronto.

• Mariners' Bryan Woo: Expected to make ALCS roster

  Rotowire Oct 11, 2025

  President of baseball operations Jerry Dipoto said Saturday that Woo (pectoral) is expected to be included on the Mariners' ALCS roster, Adam Jude of The Seattle Times reports. Woo threw a bullpen session Friday as the latest step in his recovery from right pectoral inflammation, and the Mariners seemingly are pleased enough with his progress to feel comfortable including him in their pitching plans for the ALCS against Toronto. Dipoto noted that the 25-year-old righty likely won't be available for the first few games of the series, so his postseason debut will presumably come after the series moves to Seattle for Games 3 and 4.

• Mariners' Bryan Woo: Misses out on ALDS roster

  Rotowire Oct 4, 2025

  Woo (pectoral) isn't on the Mariners' roster for the ALDS, Bob Nightengale of USA Today reports. Woo missed the final couple of weeks of the regular season due to right pectoral inflammation. He tossed a bullpen session Thursday that the Mariners considered successful, but evidently not successful enough to include him in the team's pitching plans for its ALDS matchup against the Tigers. The 25-year-old will be eligible to return in the ALCS if Seattle advances.

  Rotowire Oct 2, 2025

  Woo's (pectoral) bullpen session went as planned Thursday, Curtis Crabtree of Fox 13 Seattle reports. There weren't many details provided about Woo's throwing session, but it was deemed a success by the team. More details about his availability should come Friday, as the Mariners want to see how Woo is feeling following a day of recovery before announcing their pitching plans for the ALDS.

• Mariners' Bryan Woo: Plays catch Thursday

  Rotowire Sep 25, 2025

  Woo (pectoral) played light catch in the outfield prior to Thursday's game against the Rockies, Adam Jude of The Seattle Times reports. Woo was originally slated to start Thursday, but he was instead limited to light throwing. The team didn't release an official update on his status, and he is still considered day-to-day. Per Daniel Kramer of MLB.com, Woo's regular season is likely over, and he is targeting Game 2 of the ALDS for a return to the mound.

• Mariners' Bryan Woo: Considered day-to-day

  Rotowire Sep 20, 2025

  Imaging revealed minor inflammation in Woo's right pectoral Saturday, Ryan Divish of The Seattle Times reports. It remains unknown whether Woo will be able to make his next start Thursday versus Colorado, but the M's will keep an eye on him over the next several days before making a decision. The team doesn't anticipate him spending time on the injured list, however, which makes it far more likely that he appears on the mound at some point before the end of the year.

• Mariners' Bryan Woo: Exits with trainer

  Rotowire Sep 19, 2025

  Woo was removed from Friday's game against the Astros with an apparent injury, Chandler Rome of The Athletic reports. Woo had made it through five innings of shutout ball Friday, but a Mariners trainer made the decision to pull the right-hander while he was warming up for the sixth. It isn't immediately clear what is bothering Woo, but the team should provide some details regarding his condition relatively soon.

• Mariners' Bryan Woo: Sets personal best in strikeouts

  Rotowire Sep 14, 2025

  Woo (14-7) allowed two runs on three hits and a walk while striking out 13 over six innings to earn the win over the Angels on Saturday. Woo's 13 strikeouts were the most he's had in any game in his big-league career, and the first time he's even reached double digits. He gave up both runs in the second inning, including one on a solo home run by Jo Adell. Woo has won six of eight starts since the beginning of August, allowing just 15 runs over 48.2 innings with a 64:10 K:BB in that in that span. He is now at a 3.02 ERA, 0.94 WHIP and 191:35 K:BB through 181.2 innings over 29 starts this season. He is lined up to make his next start in a pivotal road series versus the Astros.

• Mariners' Bryan Woo: Earns 13th win

  Rotowire Sep 9, 2025

  Woo (13-7) earned the win Monday, allowing two runs on three hits and no walks over six innings in a 4-2 victory over St. Louis. He struck out nine. Woo delivered six strong innings Monday, halting a brief two-start stretch of shorter outings after previously going six-plus in each of his first 25 starts. The right-hander has been one of MLB's most reliable arms this season, compiling a 3.02 ERA and 0.95 WHIP across 175.2 innings in 28 starts. While not overpowering with strikeouts (9.1 K/9), his nine punchouts Monday tied a season high, and his elite command (1.7 BB/9) continues to fuel his consistency.

• Mariners' Bryan Woo: Bounces back Tuesday

  Rotowire Aug 6, 2025

  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 Jul 31, 2025

  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: Flirts with no-hitter Thursday

  Rotowire Jul 11, 2025

  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 Jun 28, 2025

  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 Jun 5, 2025

  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 May 31, 2025

  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 May 24, 2025

  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.
