The Diamondbacks optioned Waldschmidt to Triple-A Reno on Monday.
With Jordan Lawlar returning last week and Lourdes Gurriel (hamstring) being activated Monday, the Diamondbacks' outfield suddenly got crowded, pushing Waldschmidt back to the minors. The rookie has managed just a .180/.231/.262 batting line and 36.9 percent strikeout rate across his last 17 contests.
