Mariners general manager Justin Hollander said Wednesday that the MRI on Woo's arm "was perfectly clean," and the right-hander could be reinserted into the rotation as early as next week, Daniel Kramer of MLB.com reports.

EDGE Analysis

The 24-year-old was scratched ahead of his scheduled start Tuesday against the White Sox due to what the team labeled as a "right forearm issue," but he doesn't appear to be dealing with anything too serious. It's unclear when exactly Woo will make his next start, though it seems the Mariners will attempt to avoid putting him on the injured list.

Woo was scratched from his scheduled start Tuesday against the White Sox as the Mariners await MRI results on his right arm, Adam Jude of The Seattle Times reports.

EDGE Analysis

The right-hander missed the first six weeks of the season with elbow inflammation and is now potentially dealing with another arm issue a month later. Woo has been dominant in six starts for Seattle with a 1.07 ERA, 0.53 WHIP and 24:2 K:BB over 33.2 innings, but his outlook is now up in the air as he continues to be evaluated.

Woo will not start Tuesday's game versus the White Sox, Shannon Drayer of Seattle Sports 710 AM reports.

EDGE Analysis

The Mariners have not yet said why Woo won't start as scheduled Tuesday, but an update on his status should come in the near future. In the meantime, Jhonathan Diaz will come up from Triple-A Tacoma to start in Woo's place.

Woo (3-0) picked up the win Thursday, allowing two hits and no walks with six strikeouts across six scoreless innings against Oakland.

EDGE Analysis

Woo threw a season-high 85 pitches Thursday, an encouraging sign for the 24-year-old after he missed all of April with elbow inflammation and exited his first start after his IL stint with forearm tightness. Even with a restricted pitch count, the right-hander has generated four consecutive quality starts and has fired 12 straight scoreless innings, giving him a 1.07 ERA and 24:2 K:BB through 33.2 innings. Woo's tentatively scheduled to face the White Sox on Tuesday.

Woo allowed three hits and struck out two without walking a batter over six scoreless innings in a no-decision versus the Angels on Friday.

EDGE Analysis

Woo needed just 66 pitches (47 strikes) to complete six frames, but that was all for his start. Trent Thornton and Taylor Saucedo combined to allow four runs in the seventh inning, wiping out the Mariners' lead and Woo's chance to earn his third win of the year, but this was still a stellar outing for the 24-year-old. He's now at a 1.30 ERA, 0.58 WHIP and 28:2 K:BB over 27.2 innings across five starts. The Mariners continue to manage his pitch count, but he's completed six innings in each of his last three starts thanks to his efficiency. Woo is projected for a road start in Oakland next week.

Woo did not factor into the decision Sunday against Washington, allowing three earned runs on five hits and zero walks over six innings. He struck out one.

EDGE Analysis

Woo finally showed some signs of weakness Sunday, surrendering his first home run of the season and allowing a season-high three earned runs. Even so, the 24-year-old needed just 70 pitches to notch his second consecutive quality start. Despite not topping 80 pitches in any outing this season, Woo sits at 2-0 with a sparkling 1.66 ERA and 0.60 WHIP in 21.2 innings this season. He is tentatively scheduled to start Friday's game against the Angels.

Woo (2-0) earned the win Tuesday, yielding two hits and no walks with seven strikeouts across six scoreless innings against the Yankees.

EDGE Analysis

Woo's been excellent to start 2024, allowing just one run across 15.2 innings after missing the first month of the campaign with elbow inflammation. The 24-year-old still seems to be on a pitch count, as he only threw 77 pitches Tuesday and hasn't exceeded 80 pitches in a start this year. He's projected to make another start Sunday at Washington.

Woo (1-0) picked up the win in Wednesday's 4-2 victory over the Royals, allowing one run on three hits and a walk over 5.1 innings. He struck out five.

EDGE Analysis

The right-hander pounded the zone, firing 60 of his 79 pitches for strikes, but after five scoreless innings Woo ran out of gas in the sixth and left the mound with runners on the corners and one out, clinging to a 2-1 lead. Gabe Speier was able to escape the jam, however, and the Seattle bullpen took care of the rest. Woo has been impressive in two starts since making his belated season debut, giving up just one run in 9.2 innings with an 8:2 K:BB, but he faces a tough test in his next outing -- a road start at Yankee Stadium early next week.

The Mariners list Woo (forearm) as their probable starter for Wednesday's game against the Royals in Seattle.

EDGE Analysis

Woo missed the first six weeks of the regular season with right elbow inflammation before returning from the 15-day injured list Friday after a trio of successful rehab starts. The right-hander was cruising through his first start of the season with the Mariners in Friday's 8-1 win over the Athletics, but he was lifted after 4.1 scoreless innings and 62 pitches upon experiencing forearm tightness. Though the fact that Woo is dealing with an injury that's seemingly related to the one that kept him on the shelf earlier this season isn't ideal, manager Scott Servais downplayed concern about the forearm issue after the game. The Mariners are still seemingly anticipating that Woo will be ready to go for his next turn through the rotation Wednesday, though fantasy managers will still want to keep tabs on his status leading up to the day of the game just to ensure the team hasn't scratched him from the start.

Woo said Friday that he has been dealing with tightness in his forearm, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Woo's forearm had reportedly given him problems during his rehab assignment when he sat down for a long period of time between innings. The issue returned during the fifth inning of his start against the A's, causing him to be pulled as a precaution. Manager Scott Servais said he expects Woo to be fine, and the right-hander will likely be able to make his next start -- tentatively scheduled for Wednesday against Kansas City.
