Arihara cleared waivers and was outrighted to Triple-A Round Rock on Tuesday, Levi Weaver of The Athletic reports.
Arihara was DFA'd on Sunday after posting a 6.64 ERA, 1.43 WHIP and 24:13 K:BB across 10 starts with the Rangers. He didn't find any suitors on waivers, so he'll remain with Texas as minor-league depth for the time being. The right-hander signed a two-year, $6.2 million deal in the offseason, so the Rangers will certainly be looking for signs that he can turn things around heading into 2022.
