The Chicago Cubs have made a pair of moves to bolster their bullpen, optioning pitcher Carl Edwards Jr. to Triple-A Iowa and recalling pitchers Allen Webster and Kyle Ryan to the big league roster.

The Cubs also placed pitcher Mike Montgomery on the 10-day injured list with a left lat strain, according to the team.

To make room for Webster on the 40-man roster, the Cubs designated pitcher Jen Ho-Tseng for assignemtn.

The big news of the day was the demotion of Edwards, who has struggled out of the gate after Major League Baseball determined that his new pitching delivery was an illegal motion. Edwards gave up six earned runs in four appearances for the Cubs, and will be sent back to Iowa to get his mechanics back in order.

With Montgomery, the Cubs are hopeful that he will only have to stay on the IL for 10 days. Montgomery has given up six runs, five of which were earned, in 2.2 innings of work this season.

Ryan has not pitched in the big leagues since 2017 when he was still with the Detroit Tigers. He has appeared in one game for the Iowa Cubs this season, giving up a run in 1.2 innings of work.

As for Webster, he appeared in three games for the Cubs last season, giving up two earned runs in three appearances. He posted a 1.50 ERA in nine games for the Cubs during spring training.
