George Kirby nears throwing program start

George Kirby (shoulder) aims to start playing catch soon, per team updates, staying in Arizona for three more weeks of rehab after a March 7 shutdown for inflammation.

Fantasy Impact

Kirby, sidelined since March 7 with right shoulder inflammation and post-injection, eyes a catch start soon, targeting a mid-April Mariners return after rehab in Arizona. His timeline’s fluid. Fantasy managers in all leagues should roster him, expecting his ace-level skills to shine once back, though a mid-April debut means stashing him through early weeks.

George Kirby (shoulder) to open season on IL

George Kirby has been shut down from throwing due to right shoulder inflammation and will begin the season on the injured list, per team reports.

Fantasy Impact

Kirby’s outings left him lagging—his MRI was clean, and he pushed to keep throwing, but the Mariners shut him down with no return date set, paving the way for Emerson Hancock in the rotation. Fantasy managers should slide his SP2 value down a notch; stash him, but brace for an early absence.

George Kirby said he threw two cutters in his spring training debut on Wednesday against the Athletics.

Fantasy Impact

Kirby pitched into the second inning where he walked two hitters, which is unusual for him. He threw one cutter to Lawrence Butler leading off the game and one to Seth Brown that was fouled off. This is a pitch he added to his mix this offseason.
