SEATTLE -- The Mariners reinstated left-hander Yusei Kikuchi from the injured list on Monday in time for the All-Star Game, though he will not participate in the event.
Minnesota Twins reliever Taylor Rogers was named as his replacement.
Kikuchi was selected to the American League All-Star team for the first time in his career and would have been Seattle's lone representative in Tuesday night's game at Coors Field.
The Mariners placed Kikuchi on the injured list on Sunday, but they did not disclose an injury, and manager Scott Servais said he could not comment but wasn't concerned about Kikuchi's status.
Seattle used the open roster spot to promote top catching prospect Cal Raleigh, who made his major league debut on Sunday against the visiting Los Angeles Angels.
The Mariners optioned infielder Donovan Walton to Triple-A Tacoma and designated for assignment reliever Will Vest in order to reinstate Kikuchi.
Kikuchi has been one of the top left-handers in baseball this season, his third since signing with the Mariners and moving to the major leagues from Japan. He is 6-4 with a 3.48 ERA and 98 strikeouts.
