Arihara is scheduled to start Saturday's game against the Blue Jays at Globe Life Field.
After a three-start run following his Aug. 16 call-up from Triple-A Round Rock, Arihara shifted to the bullpen last week. He made one two-inning appearance in relief Sept. 3 but will now step back into the rotation after fifth starter Dallas Keuchel was recently released. Arihara owns a 5.29 ERA and 1.76 WHIP over 17 innings with Texas this season and doesn't profile as an inspiring fantasy option.
