Padres' Matt Waldron: Sent down after spot start

The Padres optioned Waldron to Triple-A El Paso on Wednesday.

Waldron will head back to the minors after he permitted four runs over 4.2 innings Monday while taking a loss in a spot start versus the Phillies. San Diego called up right-hander Eduarniel Nunez to replace Waldron on the 26-man active roster.
