The Toronto Blue Jays pitching staff received another shake-up on Monday.
Starter Easton Lucas was optioned to triple-A Buffalo while lefty reliever Josh Walker was called up to the big-league team, the Blue Jays said.
Lucas, 28, was roughed up in his most recent start, allowing seven hits and six earned runs while recording just five outs in a loss to the Seattle Mariners on Sunday.
The lefty filled the rotation spot vacated by Max Scherzer's injury through four turns. His first two starts featured a combined 10.1 innings of shutout baseball, but he allowed 14 runs in 6.2 innings over the last two.
Thanks to off days, Toronto won't require a fifth starter again until May 3 against Cleveland.
Walker, 30, spent last season with the New York Mets, making 10 relief appearances and recording a 5.11 ERA.
The Blue Jays signed him to a one-year deal in December. Walker will be active for Monday night's contest against the Houston Astros (8:10 p.m. ET / 5:10 p.m. PT), which you can catch live on Sportsnet and Sportsnet+.
