Woo (pectoral) won't start in his usual rotation spot Thursday, Daniel Kramer of MLB.com reports.

EDGE Analysis

General manager Justin Hollander said Tuesday that the team still doesn't plan to place Woo on the injured list, and that the right-hander will instead play catch Wednesday or Thursday rather than start a game against the Rockies. A better idea of how far away the 25-year-old is from returning will likely emerge after his throwing session.

Imaging revealed minor inflammation in Woo's right pectoral Saturday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

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.

Woo was pulled from his start Friday against Houston due to pectoral tightness, Adam Jude of The Seattle Times reports.

EDGE Analysis

Woo pitched five scoreless innings, allowing just one hit and one walk while striking out seven batters before his pec forced him to come out of the game while warming up for the sixth. He's expected to undergo an MRI on Saturday to determine the severity of his injury, at which point more will be known about his chances to make his next start -- tentatively scheduled to come Thursday against the Rockies.

Woo was removed from Friday's game against the Astros with an apparent injury, Chandler Rome of The Athletic reports.

EDGE Analysis

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.

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.

EDGE Analysis

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.

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.

EDGE Analysis

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.

Woo didn't factor into the decision Tuesday against the Rays, allowing three runs on four hits and three walks across five innings. He struck out three.

EDGE Analysis

Woo's three strikeouts were his fewest in 14 starts and tied his season low, while his three walks were a season worst. The 25-year-old has now failed to complete six innings in back-to-back outings after doing so in his first 25 appearances of the campaign. Still, Woo boasts a 3.02 ERA and a 0.97 WHIP in 169.2 innings pitched this season. He's tentatively scheduled to face the Cardinals for his next start.

Woo (12-7) earned the win Wednesday over the Padres, allowing two runs on six hits and a walk over 5.2 innings. He struck out six.

EDGE Analysis

Woo held San Diego scoreless through five innings before giving up a pair of runs in the sixth, though the Mariners would manage to hang on for a 4-3 win, giving the right-hander his fourth victory in his last five outings. Despite the win, Woo failed to make it through six innings for the first time in 26 starts this season -- the right-hander's streak of 25 straight starts of six-plus innings marked a Seattle franchise record. Overall, Woo sports a 2.95 ERA with a 0.95 WHIP and 166:31 K:BB across 164.2 innings. Woo's currently scheduled to face the Rays on the road his next time out.

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.

EDGE Analysis

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, making this the first month where he's yet to sprinkle in a poor outing. 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.

Woo (10-7) took the loss against the Mets on Saturday, allowing one run on six hits and two walks with eight strikeouts over six innings.

EDGE Analysis

Woo gave up a run in the third inning but was otherwise sharp, throwing 65 of 101 pitches for strikes while holding the Mets to just one extra-base hit. The 25-year-old notched his 18th quality start and has now worked at least six innings in all 24 of his outings. He'll carry a 3.02 ERA, 0.97 WHIP and 153:28 K:BB across 152 innings into a road matchup with the Athletics next weekend.
