Woo did not factor into the decision in Friday's 6-5 loss to the Angels, allowing four runs on nine hits and two walks over 3.1 innings. He struck out just one.

EDGE Analysis

Despite his fastball clocking in at 94.9 mph, up 0.2 mph from his season average, Woo looked rusty in his return from a hamstring injury against an unspectacular Angels lineup. The Seattle right-hander generated only six whiffs out of his 66 pitches and allowed a career-high nine hits. Even with this poor performance, Woo closes out the first half with a 2.45 ERA, 0.89 WHIP and 29:5 K:BB across 44 innings. He currently lines up to face the Angels again at home in his next start after the All-Star break.

The Mariners reinstated Woo (hamstring) from the 15-day injured list ahead of his start Friday against the Angels.

EDGE Analysis

Woo made his lone rehab start with High-A Everett on July 6, when he threw 45 pitches over 2.2 innings and allowed two runs on one hit and two walks while striking out two. In his eight starts prior to landing on the injured list June 25 with a strained hamstring, Woo went 3-1 with a 1.77 ERA, 0.69 WHIP and 28:3 K:BB across 40.2 innings. To make room on the 26-man roster for Woo, the Mariners optioned right-hander Eduard Bazardo to Triple-A Tacoma.

Manager Scott Servais said Tuesday that Woo (hamstring) will return from the injured list during Seattle's upcoming series against the Angels, Daniel Kramer of MLB.com reports.

EDGE Analysis

Servais didn't specify exactly what day Woo will return to start, though his turn in the rotation would come up Friday. The 24-year-old had been dominant in eight starts prior to landing on the IL with a strained hamstring, posting a 1.77 ERA and 0.69 WHIP in 40.2 innings. However, he threw just 45 pitches in 2.2 frames during his lone rehab start Saturday, so Woo will most likely be working under a relatively low pitch count in his return to a major-league mound.

Woo (hamstring) threw 45 pitches and allowed two runs on a hit with two walks and two strikeouts over 2.2 innings during his rehab start with High-A Everett on Saturday, Daniel Kramer of MLB.com reports.

EDGE Analysis

The 24-year-old rejoined the Mariners on Sunday, but manager Scott Servais was non-committal on whether the right-hander will require an additional rehab outing. The club wants Woo to be able to cover at least four or five innings before being reinserted into the big-league rotation, so it wouldn't be surprising if he's sent on another rehab outing to further build up his workload before being activated.

Woo (hamstring) will begin a rehab assignment with High-A Everett this weekend, Daniel Kramer of MLB.com reports.

EDGE Analysis

Woo came out of a bullpen session Wednesday with no concerns, clearing the way for him to make a rehab start. Mariners manager Scott Servais wouldn't rule out a return before the All-Star break for Woo, so it sounds like the right-hander could need just the one rehab outing if all goes well.

The Mariners placed Woo on the 15-day injured list Tuesday with a right hamstring strain, Shannon Drayer of SeattleSports.com reports.

EDGE Analysis

It's being classified as a low-grade strain, so perhaps Woo has a chance to return when his 15 days are up or shortly after. Emerson Hancock would normally be the obvious candidate to step into the Mariners' rotation in Woo's place, but his status is unclear after he exited his last start at Triple-A Tacoma with lower-back tightness. Jhonathan Diaz, who's struggled at the big-league level this season (5.06 ERA, 1.88 WHIP) but has an 8-1 record and 3.26 ERA at Tacoma, is another candidate.

Woo was removed from Monday's game against the Rays due to right hamstring tightness.

EDGE Analysis

Woo left his start with the team trainer after suffering what looked to be a right leg injury, and he's since been diagnosed with a hamstring issue. The team should have a better idea of whether he'll require a trip to the injured list after further evaluation, and he's set to undergo an MRI on Tuesday, per Daniel Kramer of MLB.com.

Woo left Monday's contest in the fourth inning due to an apparent right leg injury, Shannon Drayer of SeattleSports.com reports.

EDGE Analysis

Woo pitched three scoreless innings, allowing four hits while striking out three batters to open his outing Monday. He then surrendered a leadoff single to Richie Palacios in the bottom of the fourth inning and was removed thereafter with a right leg injury. Woo was visibly upset after tweaking something in his leg and a more exact diagnosis will likely come in the near future.

Woo (3-1) took the loss to the Guardians on Wednesday, allowing three runs on four hits and one walk with one strikeout over four innings.

EDGE Analysis

Woo struggled early, allowing an RBI single by Josh Naylor in the first inning and a two-run home run by Steven Kwan in the second. He rebounded with two scoreless innings but was pulled after just 64 pitches with a 3-0 deficit. Considering he hasn't pitched since June 6 with a forearm injury, the Mariners were likely just being cautious with Woo's workload. Woo still owns a sparkling 1.67 ERA and 0.61 WHIP in 37.1 innings, but his current 5.97 K/9 is well below his 9.55 rate last season. He tentatively lines up to face the Rays early next week.

Woo (forearm) is expected to start Wednesday on the road against the Guardians, Adam Jude of The Seattle Times reports.

EDGE Analysis

Woo was forced to miss his last scheduled start Tuesday versus the White Sox due to right forearm discomfort, but after a clean MRI, he appears set to return to the mound in Cleveland. The 24-year-old has produced a sparkling 1.07 ERA and 0.53 WHIP while striking out 24 batters over 33.2 innings in six starts this season.
