Mariners Look to Avoid Sweep as Bryan Woo Anchors the Mound

For a Mariners rotation that’s been snakebitten by injuries this season, Bryan Woo has emerged as a surprising stabilizer. As Seattle tries to salvage the final game of its home series against the Baltimore Orioles on Thursday, all eyes turn to the 24-year-old righty — and for good reason.

Woo (5-2, 2.82 ERA) is currently the only pitcher in MLB to go at least six innings in every one of his starts this season — a remarkable feat of endurance and consistency. Through 11 starts, he hasn’t just held down the fort — he’s kept the Mariners in the thick of the AL West race.

“You don’t expect the injuries and stuff for our staff, as healthy and consistent as we’ve been the last couple years,” Woo said. “Really, just trying to hold it down until those guys get back and we get back to doing what we do.”

With Logan Gilbert, George Kirby, and Bryce Miller all spending time on the IL, Woo has stepped up in a big way — something few predicted heading into 2024.

A Wake-Up Call Sparked Woo’s Transformation

Rewind to August 2023, and Bryan Woo’s future in the rotation looked uncertain. After multiple IL stints and a stretch where he couldn’t get through five innings, he needed a reset.

That’s when catcher Cal Raleigh delivered a tough-love message: preparation was everything. “You’ve got to put in the work every day,” Woo recalled. “There’s no, ‘Oh, I’m going to take it easy for four days.’”

It was a lesson Woo took to heart. Since that turning point, he’s pitched six-plus innings in 17 of his last 18 starts, flipping the narrative from injury-prone to workhorse.

“He’s figured out how to prepare like a pro,” said Mariners pitching coach Pete Woodworth. “That was the turning point.”

Orioles Counter With Eflin in Search of Sweep

Trying to complete a sweep on the road, the Orioles will hand the ball to Zach Eflin (4-2, 4.46 ERA). Eflin is coming off his best outing of the year — seven scoreless innings in a 2-1 win over the White Sox. He allowed just four hits and struck out a season-high six.

Though Baltimore sits at the bottom of the AL East, they’ve caught fire, winning five straight and eight of their last 10. They rallied for a 3-2 win Wednesday night, thanks to a clutch two-run triple by Heston Kjerstad in the seventh.

Adley Rutschman added a 415-foot home run in front of a hometown crowd — the All-Star catcher grew up in Portland and starred at Oregon State.

“He’s home and there’s something to that,” said interim manager Tony Mansolino. “He looks really good right now.”
