Mariners' Bryan Woo: Overcomes early homer for 10th win
Woo (10-9) earned the win against the Red Sox on Tuesday, allowing one run on five hits and one walk while striking out seven across six innings.
Mickey Gasper hit a solo homer in the first inning, but Woo settled in to keep the Red Sox off the board for the rest of his outing. It was the third time in eight starts that Woo struck out at least seven batters, and he did enough to come away with his 14th quality start of the season, which is tied for sixth-most in the American League. He'll take a 4.25 ERA and 1.09 WHIP over 148.1 innings into his next start, which is lined up for this weekend at home against the Athletics.

Mariners' Bryan Woo: Stumbles vs. Phillies
Woo (9-9) took the loss Wednesday against the Phillies, allowing six runs on five hits and a walk over four innings. He struck out five.
Woo was limited to 76 pitches Wednesday after missing his last start due to shoulder soreness, though he may have gotten an early hook regardless -- the Phillies tagged Woo for six runs over the first two frames, highlighted by a pair of home runs. In his previous three starts, Woo had given up just two runs across 18 innings while posting a 0.67 WHIP. His ERA now sits at 4.36 on the season with a 1.10 WHIP and 142:30 K:BB over 25 starts (142.1 innings). Woo will look to bounce back his next time out, which is tentatively lined up for next week in Boston.

Mariners' Bryan Woo: Optimistic after bullpen session
Woo (shoulder) completed a successful bullpen session Sunday, Daniel Kramer of MLB.com reports.
Woo last pitched Aug. 16 against the Astros, exiting that contest after having tossed six innings of two-run ball while throwing 75 total pitches. The right-hander was lifted due to right shoulder soreness, and his next turn in the rotation was skipped. Woo came out of Sunday's bullpen session feeling optimistic about the shoulder, and he outlined that he doesn't think that his season is in jeopardy, but he still wants to be cautious. Woo is currently occupying a spot on the 26-man active roster, and if he can't pitch in the near future, he will need to be placed on the injured list. The Mariners are expected to make a decision on the 26-year-old's status the team's series opener against the Phillies on Monday.

Mariners' Bryan Woo: Confident he'll start Wednesday
Woo (shoulder) said Monday that he's "100 percent confident" he will make his scheduled start Wednesday against the Phillies at T-Mobile Park, Adam Jude of The Seattle Times reports.
Woo last pitched Aug. 16 against the Astros, with a sore right shoulder causing him to miss his most recent turn through the rotation this past weekend. He felt optimistic about his shoulder after throwing a bullpen session Sunday, and barring any setbacks, the right-hander looks set to re-enter the rotation for Wednesday's series finale. Over 24 starts this season, Woo has gone 9-8 with a 4.10 ERA, 1.08 WHIP and 137:29 K:BB across 138.1 innings.

Mariners' Bryan Woo: Will throw bullpen Sunday
Woo (shoulder) is scheduled to throw a bullpen session Sunday, Daniel Kramer of MLB.com reports.
Woo was removed from his most recent start last Sunday against the Astros after experiencing soreness in his right shoulder. The Mariners skipped Woo's subsequent turn in the rotation, but he was able to throw a bullpen session Thursday and will repeat the activity Sunday. How he comes out of Sunday's session will determine when the Mariners slot him back into their rotation during the upcoming week, per Kramer.

Mariners' Bryan Woo: Won't start against Cubs
Manager Dan Wilson said Friday that Woo (shoulder) will not start during Seattle's weekend series against the Cubs, Daniel Kramer of MLB.com reports.
Woo was removed from his most recent start Sunday against Houston after feeling soreness in his right shoulder, and although he was able to throw his normal between-starts bullpen session Thursday, the M's are still going to give the 26-year-old some extra time to recover. Wilson noted that he's optimistic Woo won't have to spend time on the injured list, though it's unknown when his next start will be. Kade Anderson will come up from Double-A to make his MLB debut Saturday, and Bryce Miller will move up in the rotation to start Sunday's series finale.

Mariners' Bryan Woo: Throws bullpen session Thursday
Woo (shoulder) threw his normal between-starts bullpen session Thursday, Zach Sweet of MLB.com reports.
Woo had to leave his last outing versus the Astros on Sunday after 75 pitches because of right shoulder soreness. However, Woo and the Mariners downplayed the issue at the time, and he appears in line to make his next scheduled start Saturday against the Cubs, provided he bounces back from Thursday's mound work with no hiccups.

Mariners' Bryan Woo: Dealing with shoulder soreness
Woo (shoulder) was lifted after throwing 75 pitches in Sunday's 3-2 win over the Astros, Shannon Drayer of SeattleSports.com reports.
Woo finished his day having tossed six innings, allowing two runs on three hits and walk while striking out five batters on his way to a win. The right-hander began experiencing right shoulder soreness, and as a result, he was removed from the game after six frames. Manager Dan Wilson described the decision as precautionary, and Woo said the soreness was "nothing he was concerned about." With the victory, Woo now owns a 9-8 record with a 4.10 ERA and 137 strikeouts over 138.1 innings in 24 starts this season.

Mariners' Bryan Woo: Tosses five scoreless frames
Woo did not factor into Tuesday's decision against the Yankees, allowing three hits and one walk while striking out five across five scoreless innings.
Woo worked around two baserunners in the first inning before allowing just two more Yankees batters on base over the next four frames. He sported a 6.32 ERA and 1.56 WHIP over 31.1 innings spanning six starts from June 24 to July 30, but he's kept his opponents scoreless in back-to-back starts and is up to seven consecutive outings in which he's struck out at least five batters. Woo will take a 4.15 ERA and 1.10 WHIP over 132.1 innings into his next start, which is lined up for this weekend on the road against the Astros.

Mariners' Bryan Woo: Strong showing in win
Woo (8-8) allowed three hits, one walk and three hit batsmen while striking out five over seven scoreless innings to earn the win over the Tigers on Wednesday.
While Woo didn't have his sharpest control, the Tigers weren't able to get a run off of him. He's now allowed just five runs (four earned) across his last 26.1 innings at home, but his success in those games has been offset by a 6.16 ERA on the road since the start of June. Overall, he has a 4.31 ERA, 1.12 WHIP and 127:27 K:BB through 127.1 innings across 22 starts this season. Woo's next start is projected to be on the road versus the Yankees.

Mariners' Bryan Woo: Surrenders five runs in loss
Woo (7-8) took the loss against the Dodgers on Thursday, allowing five runs on five hits and two walks while striking out eight batters over five innings.
The big blow against Woo was a three-run homer by Dalton Rushing in the fourth inning. Beyond that, the right-handed hurler pitched pretty well, racking up 17 whiffs among his 91 total pitches. Woo finished with eight punchouts -- his most since June 18 -- but he's taken two straight losses, giving up exactly five runs in exactly five frames in both defeats. He'll carry a disappointing 4.56 ERA into his next start, which lines up to be a home matchup against Detroit.
