Woo (forearm) played catch Monday, Shannon Drayer of Seattle Sports 710 AM reports.

EDGE Analysis

It has been less than a week since Woo landed on the injured list, and he has already been given the green light to throw, which backs up last week's report that the Mariners are not concerned about the injury. Woo could throw a bullpen session soon, and barring any setbacks could rejoin Seattle's rotation as early as next week.

Mariners general manager Justin Hollander said Tuesday that there are "no real concerns" with Woo's right forearm, Daniel Kramer of MLB.com reports.

EDGE Analysis

Woo was placed on the 15-day injured list Tuesday afternoon due to right forearm inflammation, but Hollander called that a precautionary move and expressed optimism that the 23-year-old will only have to miss a couple of weeks. Emerson Hancock is getting the call Wednesday to fill the rotation vacancy in Seattle.

Seattle placed Woo on the 15-day injured list Tuesday with right forearm inflammation.

EDGE Analysis

The severity of the issue is unclear, but Woo will miss at least a couple of turns through the rotation. The 23-year-old right-hander has turned in a 4.75 ERA, 1.24 WHIP and 60:17 K:BB in his first 11 major-league starts covering 55 innings. Emerson Hancock is likely to be called up from Double-A Arkansas to replace Woo in the rotation on Wednesday versus the Padres.

Woo pitched six innings against the Angels on Thursday, allowing two runs on four hits and two walks while striking out six batters in a no-decision.

EDGE Analysis

Woo got through five scoreless frames before the Angels tagged him for two runs in the sixth. The right-hander departed in line for a tough loss but was let off the hook when Seattle rallied for four runs in the ninth. Woo got back on track in the strikeout department, fanning six batters after failing to record a punchout over five frames in his previous outing. His quality start Thursday was the third of his rookie campaign so far.

Woo pitched five innings against Arizona on Saturday, allowing three runs on seven hits and two walks while striking out zero batters in a no-decision.

EDGE Analysis

Woo came into the contest with 54 punchouts over 44 big-league frames, so it was surprising to see him tally five innings without recording a single strikeout. Despite that oddity, the rookie righty managed a respectable showing, keeping Arizona off the scoreboard through three frames before allowing three runs over the fourth and fifth. Woo's ability to miss bats is perhaps his most alluring asset in fantasy, and it's logical to expect this outing to be an aberration in that regard. Still, Woo's a risky pitcher to roster in fantasy redraft leagues given a few shaky starts this season as well as the likelihood that he'll be shut down at some point to limit his workload.

Woo (1-3) allowed four runs on four hits and a walk over six-plus innings Sunday, striking out seven and taking a loss against Toronto.

EDGE Analysis

Woo tossed three scoreless frames before coughing up a two-run shot to Vladimir Guerrero in the fourth inning. Woo's given up multiple homers in two straight games after being taken deep just once in his previous four outings. Following a stretch of six consecutive starts allowing two or fewer runs, he's been tagged with 10 runs over his last two appearances. While his ERA rose to 4.91, he's sporting a strong 54:13 K:BB across 44 career MLB innings. Woo's next start is projected to be in Arizona.

Woo (1-2) allowed seven runs (six earned) on eight hits and three walks while striking out four over 3.1 innings to take the loss Tuesday versus the Twins.

EDGE Analysis

Woo hadn't given up more than two runs in any of his six previous starts, but he struggled after a 10-day gap between outings. The Twins got to him for two runs in the first inning and then piled on in the third and fourth. Woo is now at a 4.74 ERA, 1.26 WHIP and 47:12 K:BB over 38 innings through eight starts this season. He's lined up for a home start versus the Blue Jays this weekend.

Woo allowed two runs (one earned) on three hits and a walk while striking out four over six innings in a no-decision versus the Astros on Saturday.

EDGE Analysis

Woo was arguably a little sharper than opposing starter Framber Valdez, but both pitchers exited with the game tied 2-2. This was Woo's second straight quality start, and it took him just 78 pitches (50 strikes) to complete six frames. While the four strikeouts matched a season low, he's allowed no more than two runs in each of his last six outings. He's at a 3.63 ERA, 1.07 WHIP and 43:9 K:BB through 34.2 innings over seven starts. The Mariners intend to be careful with the 23-year-old rookie -- he'll likely begin the second half in the rotation, but it's expected he'll be shut down at some point before the end of the season to manage his workload.

Woo, who could still make one more start before the All-Star break Saturday at Houston, is expected to be shut down at some point in the second half of the season in order to preserve his arm, Daniel Kramer of the team's official site reports.

EDGE Analysis

The rookie right-hander has been outstanding after stumbling out of the gate against the dangerous Rangers in his first major-league start back on June 3, pitching to a 1-0 record, 2.36 ERA, 0.94 WHIP and 11.8 K/9 across the 26.2 innings covering his subsequent five outings. However, the Mariners have said all along they'll be careful with Woo, who, when factoring in the 44 frames he logged at Double-A Arkansas before his promotion, has already surpassed the 56 innings he pitched in 2022. General manager Justin Hollander has already alluded to the likelihood Woo will be shut down altogether at some point during the second half, adding "we're not just purely measuring innings; we're measuring stressful innings, how hard they're working in any given outing."

Woo allowed two runs on three hits and two walks while striking out seven over six innings, taking a no-decision in Monday's 6-5 win over the Giants.

EDGE Analysis

Woo pitched well and completed six innings for the first time, earning his first quality start. The right-hander has allowed two runs or fewer in each of his last five starts, though he has just one win to show for it. He's at a 4.08 ERA, 1.15 WHIP and 39:8 K:BB through 28.2 innings over six career starts. He's in line for one more start before the All-Star break, a weekend road outing versus the Astros.
