Silseth will be recalled from Triple-A Salt Lake on Wednesday to start against the Yankees, Erica Weston of Bally Sports West reports.
Silseth was optioned to Triple-A on June 3 and has since put up a 4.50 ERA and 1.14 WHIP through 22 innings across five starts. Despite the relatively unremarkable numbers, he'll be called upon to start Wednesday, joining the rotation as a replacement for Jaime Barria, who has been working out of the bullpen since the All-Star break. Silseth has only two major-league appearances this season that lasted at least three innings.
