Doval was optioned to Triple-A Sacramento on Friday.
Doval was called up Tuesday, and he allowed a hit and no walks while striking out four in two scoreless innings Thursday against the Rockies. He's recorded a 5.33 ERA in 25.1 relief innings in the minors and will head back to Triple-A after Anthony DeSclafani (shoulder) was reinstated from the 10-day injured list.
