The Mariners announced that right-hander Casey Lawrence has cleared waivers and been sent outright to Triple-A Tacoma, thus reducing the team’s 40-man roster to a count of 39. The veteran of eight minor league seasons can reject in favor of free agency. Lawrence, 30, joined the Blue Jays organization in 2010 after going undrafted and ultimately worked his way to the Major Leagues for the first time in 2017. Toronto brought Lawrence to the Majors in early April but designated him for assignment a month later, leading to a waiver claim by the Mariners.
