Woo was removed from his start Friday against Oakland due to an apparent injury, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Woo appeared to be reluctant to come out of the game, but the Mariners' training staff saw something they didn't like and decided to pull the right-hander. In his first start of the season after working his way back from elbow inflammation, Woo pitched 4.1 scoreless innings and struck out three batters while walking one. It remains unknown if his latest injury is related to his elbow, but clarification should come relatively soon.

The Mariners reinstated Woo (elbow) from the 15-day injured list prior to his start Friday versus Oakland.

EDGE Analysis

Woo will be making his season debut after missing the first month-plus of the season due to right elbow inflammation. The 24-year-old was spectacular during his rehab assignment, striking out 17 batters in 11.1 scoreless innings, and he'll get a chance to stay hot against a below-average Athletics lineup. Tyson Miller was designated for assignment in a corresponding move.

Woo (elbow) is expected to be activated from the 15-day injured list to start Friday's game against the Athletics, Shannon Drayer of Seattle Sports 710 AM reports.

EDGE Analysis

Woo has been on the injured list all year due to right elbow inflammation, but he has now been given the green light to make his season debut with the Mariners. The 24-year-old righty did not give up a run through 11.1 innings during his three rehab starts at Triple-A Tacoma, and he managed to strikeout 17 batters while walking none. Emerson Hancock is expected to be optioned to Tacoma once Woo is activated.

Woo (elbow) is expected to rejoin the Mariners' rotation during their upcoming homestand, Ryan Divish of the Seattle Times reports.

EDGE Analysis

Manager Scott Servais wasn't ready to give an exact date for Woo's return but noted that it will be a day which would allow for an extra day of rest for the team's other starters. That would seem to point to Woo starting Friday against the Athletics, but the exact plans should be revealed soon. Emerson Hancock will be optioned to Triple-A Tacoma when Woo returns.

Woo (elbow) struck out six and allowed three hits and no walks over five shutout innings in his third rehab start Saturday with Triple-A Tacoma.

EDGE Analysis

Woo was about as sharp as the Mariners could have hoped in what was likely the final start of his rehab assignment, as he built up to 66 pitches (44 strikes) while making quick work of the Triple-A Sacramento lineup. Provided Woo experiences no complications with his right elbow during a bullpen session within the next couple of days, he should be cleared to return from the 15-day injured list to make his 2024 Mariners debut later this week. Emerson Hancock has been filling in as the Mariners' No. 5 starter while Woo has been out, but Seattle could have room in the rotation for both hurlers if George Kirby (knee) is forced to the 15-day IL. Woo is likely to be activated to start either Thursday in Minnesota or Friday at home versus the Athletics.

Woo (elbow) fired 3.1 scoreless innings in a rehab start for Triple-A Tacoma against El Paso on Saturday, allowing two hits and recording six strikeouts.

EDGE Analysis

Woo was impressive for the second time in as many rehab starts, locating 31 of his 49 pitches for strikes and keeping his ERA unblemished over 6.1 rehab innings overall. Per MLB.com, Woo threw all five of his pitches and topped out at 95 mph; according to general manager Justin Hollander, the plan is for the young right-hander to make at least one more rehab start with a goal of reaching 85 pitches, after which activation from the injured list would be considered.

Woo (elbow) struck out five over three perfect innings in his first rehab start with Triple-A Tacoma on Sunday.

EDGE Analysis

Woo needed just 35 pitches to cruise through his three frames in a difficult pitching environment in Las Vegas. The velocity on his four-seamer was down a bit at 93.9 miles per hour, but that's not overly concerning considering it was his first game action in more than a month. Woo is in line for multiple rehab starts but could be ready to rejoin the Mariners rotation by early May.

Woo (elbow) is making a rehab start with Triple-A Tacoma on Sunday in Las Vegas, Ryan Divish of The Seattle Times reports.

EDGE Analysis

The right-hander went down with elbow inflammation late in spring training but has now been cleared for game action. Woo will likely require multiple starts in the minors before joining the Mariners, so he could make his season debut in early May.

Woo (elbow) threw an up-down bullpen session Friday and could head out on a rehab assignment with Triple-A Tacoma at some point next week, SeattleSports.com reports.

EDGE Analysis

The update comes via Mariners general manager Justin Hollander, who added Woo will need to get in a live batting practice as his next step before engaging in a three-inning rehab start. Woo would likely be set for two rehab starts overall with the Rainiers whenever he does make it down to the farm, per Hollander, and he then would be evaluated for possible activation.

Woo (elbow) has begun a throwing program, Shannon Drayer of Seattle Sports 710 AM reports.

EDGE Analysis

Woo was shut down for a little over a week with right elbow inflammation but is ready to get built back up. It shouldn't take too terribly long for that to happen since he was fully stretched out by late March, but the Mariners won't establish a timetable for Woo's return until he makes further strides.
