Castellani was returned to Triple-A Albuquerque following Tuesday's doubleheader against the Giants.

Castellani served as the 27th man in Tuesday's twin bill and made his season debut as the starter in the nightcap. The right-hander allowed two runs on five hits and four walks while striking out two in 3.1 innings. He didn't factor into the decision and will now head back to Triple-A Albuquerque with the minor-league season is underway.
