Seattle Mariners starting pitcher Bryan Woo is set to throw off a mound Thursday for the first time since leaving the team’s Sept. 19 game at Houston with mild inflammation in his right pectoral muscle.

Mariners manager Dan Wilson told reporters during a Wednesday media session that he’s optimistic Woo (15-7, 2.94 ERA) will be on the roster for the team’s American League Division Series against either the Cleveland Guardians or Detroit Tigers.

Woo will not take part in the team’s intra-squad scrimmage, instead throwing a bullpen session. The team wants him to throw at least twice before he makes an ALDS start, pushing back his timeline to likely Game 3.

“Seems like things are going according to plan,” Wilson said.

Woo, 25, last threw five innings 12 days ago, leaving in the middle of warmups before starting his sixth inning of work. The right-hander has been a model of consistency this season for Seattle, throwing at least six innings in 27 of his 30 starts while finishing fourth in the AL in wins and fifth in ERA.

With Woo unlikely to start the first two games of the ALDS, the Mariners likely will turn to either Logan Gilbert, Luis Castillo and George Kirby to start their two home games to begin the postseason.
