The Diamondbacks optioned Strowd to Triple-A Reno on Monday.
Arizona called Strowd up from Triple-A on Friday, but he didn't end up pitching out of the bullpen during the team's weekend series against the Dodgers. He'll head back down to Triple-A, where he's submitted a 6.63 ERA and 1.85 WHIP over 36.2 innings. In a corresponding move, Arizona reinstated Michael Soroka (glute) from the 15-day injured list ahead of his scheduled start Monday against Colorado.
